Abstract
BACKGROUND Rotator cuff disorders include a broad spectrum of pathological conditions including partial-thickness and full-thickness tears. Studies have shown partial-thickness rotator cuff tear (PTRCT) prevalence to be twice that of full-thickness tears. In the working population, PTRCTs are one of the most common causes of shoulder pain and often result in occupational disability due to pain, stiffness, and loss of shoulder function. Treatment of PTRCTs remains controversial. The purpose of this study was to consolidate the existing high-quality evidence on best management approaches in treating PTRCTs using both nonoperative and operative approaches. METHODS A scoping review with best evidence synthesis was performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. MEDLINE (OVID), EMBASE (OVID), Cochrane Library (Wiley), SCOPUS, Web of Science Core Collection, CINAHL Plus with Full Text (EBSCOhost), PubMed Central, and Science Direct were searched from 2000 to March 3, 2023. Level 1 studies, and systematic reviews and meta-analyses that included level 1 and 2 studies, were included. RESULTS The search yielded 8276 articles. A total of 3930 articles were screened after removing 4346 duplicates. Application of inclusion criteria resulted in 662 articles that were selected for full-text review. Twenty-eight level 1 studies, 1 systematic review, 4 meta-analyses, and 1 network meta-analyses were included in the best evidence synthesis. Nonoperative strategies included injections (ie, platelet-rich plasma, corticosteroid, prolotherapy, sodium hyaluronate, anesthetic, and atelocollagen), exercise therapy, and physical agents. Operative interventions consisted of débridement, shaving of the tendon and footprint, transtendon repair, and traditional suture anchor repair techniques with and without tear completion. Both nonoperative and operative strategies demonstrated effectiveness at managing pain and functional outcome for PTRCTs. The evidence supports the effectiveness of surgical intervention in treating PTRCTs regardless of arthroscopic technique. CONCLUSION The results of this scoping review do not support superiority of operative over nonoperative management and suggest that both strategies can be effective at managing pain and functional outcome for PTRCTs. Surgery, however, is the most invasive and costly approach, with the highest risk of complications such as infection. Other variables such as patient expectation, treating practitioner bias, or preference may change which modalities are offered and in what sequence.

Abstract
PURPOSE Rotator Cuff (RC) lesions are classified in full-thickness and partial-thickness tears (PTRCTs). To our knowledge, no studies investigated the mean size of shoulder tendons in healthy and PTRCT patients using MRI scans. The aim of the study was to provide data to obtain and compare the mean value of tendon sizes in healthy and PTRCTs groups. METHODS From 2014 to 2020, 500 were included in the study. They were divided into two groups: Group 1 (100 subjects) was composed of people positive for partial-thickness rotator cuff tears (PTRCTs), while the 400 subjects in Group 2 were negative for PTRCTs. RESULTS Overall, of the patients included in the study, 231 were females and 269 were males. The mean age of the patients was 49 ± 12.7 years. The mean thickness of the supraspinatus tendon (SSP) was 5.7 ± 0.6 mm in Group 1, 5.9 ± 0.6 mm in Group 2 (p < 0.001). The mean length of the ISP tendon was 27.4 ± 3.2 mm in Group 1, 28.3 ± 3.8 mm in Group 2 (p = 0.004). The mean width of the SSP tendon was 17 ± 1.6 mm in Group 1, 17.6 ± 2 mm in Group 2 (p = 0.004). The mean width of the infraspinatus tendon (ISP) tendon was 17.7 ± 1.4 mm in Group 1, 18.3 ± 2.1 mm in Group 2 (p = 0.02). CONCLUSION The anatomical data present in this paper may serve as a tool for surgeons to properly manage PTRCTs. The findings of the present study aimed to set the first step towards reaching unanimity to establish international cut-off values to perform surgery. Additionally, they could widely increase diagnostic accuracy, improving both conservative and surgical approaches. Lastly, further clinical trials using more accurate diagnostic MRI tools are required to better define the anatomical differences between PTRCT and healthy patients. LEVEL OF EVIDENCE Level II, Retrospective Comparative Trial.

Abstract
BACKGROUND Conservative management has emerged as an attractive option for partial thickness rotator cuff tears (PT-RCTs). A single algorithmic treatment strategy for patients with symptomatic PT-RCT has not yet been developed. This systematic review aims to ascertain whether a conservative approach to PT-RCTs yields positive results in terms of clinical outcomes and functional recovery. METHODS This is a systematic review of the literature on patients with PT-RCTs receiving conservative treatment with physiotherapy, platelet-rich plasma (PRP) injections, collagen injections, hyaluronic acid (HA) injections, or corticosteroids injections coupled with polydeoxyribonucleotide (PDRN). Outcomes such as the Visual Analog Scale (VAS) for pain, American Shoulder and Elbow Surgeons and Constant-Murley Score evaluations, as well as the Shoulder Pain and Disability Index and Euro Quality of Life-5D questionnaires were reported following a conservative approach. RESULTS Eleven studies were included. Six articles explored the outcomes of patients with PT-RCT treated with PRP injections. Significant improvements in VAS for pain were observed. Two studies examined collagen injections and reported variations in VAS for pain and Constant-Murley Score. Sodium hyaluronate and HA injections were studied in two other articles, showing notable improvements in American Shoulder and Elbow Surgeons scores. Corticosteroid and PDRN injections also displayed favorable outcomes. In addition, physical therapy protocols demonstrated improvements in VAS for pain and strength, particularly with eccentric rehabilitation. CONCLUSIONS Conservative management of PT-RCTs, involving physical therapy, PRP injections, collagen injections, corticosteroid injections, HA injections, and PDRN in jections, demonstrates favorable clinical outcomes. In addition, favorable results are observed in terms of decreased tear width and improved strength recovery, at least during a short-term follow-up. Unfortunately, long-term insight into the structural integrity of conservatively treated rotator cuff tendons following a partial injury has not been thoroughly evaluated yet. STUDY DESIGN LEVELS OF EVIDENCE Level IV-systematic review.

Abstract
OBJECTIVE Patch technology has been the new technique in the treatment of partial thickness of the rotator cuff tear (PTRCTs) to address the limitation of traditional techniques. Compared with allogeneic patches and artificial materials, coracoacromial ligament is obviously closer to their own biology. The purpose of the study was to evaluate the functional and radiographic outcomes following arthroscopic autologous coracoacromial ligament augment technique for treatment of PTRCTs. METHOD This study included three female patients with PTRCTs who underwent arthroscopy operation in 2017 with an average age of 51 years (range from 50 to 52 years). The coracoacromial ligament implant was attached to the bursal side surface of the tendon. The clinical results were evaluated by American Shoulder and Elbow Surgeons (ASES) score, Simple Shoulder Test (SST), acromiohumeral distance (AHD) and muscle strength before and 12 months after operation. Magnetic resonance imaging (MRI) was performed 24 months after operation to assess the integrity of the anatomical structure of the original tear site. RESULT The average ASES score improved significantly from 57.3 preoperatively to 95.0 at 1-year follow-up. The strength improved significantly from grade 3 preoperatively to grade 5 at 1 year. Two of three patients underwent the MRI at 2-year follow-up. Radiographic released the complete healing of rotator cuff tear. No implant-related serious adverse events were reported. CONCLUSION The new technique of using autogenous coracoacromial ligament patch augment provides good clinical results on patients with PTRCTs.

Abstract
Background Augmentation with subacromial bursa has not been fully established in bursal-sided partial-thickness rotator cuff tears (PT-RCTs). Purpose To compare the results of acromioplasty + arthroscopic debridement versus acromioplasty + augmentation with subacromial bursa for Ellman type 2 PT-RCTs involving 25% to 50% of the tendon surface area. Study Design Cohort study; Level of evidence, 3. Methods Included were 40 patients (mean age, 47.8 years) with Ellman type 2 PT-RCTs whose symptoms did not regress despite 3 months of nonoperative treatment. The patients underwent either acromioplasty + debridement (group A; n = 18) or acromioplasty + augmentation (group B; n = 22). Outcome scores (visual analog scale [VAS] pain score, Constant-Murley score [CMS], and American Shoulder and Elbow Surgeons [ASES] score) were obtained preoperatively and at 6, 12, and 18 months postoperatively. Magnetic resonance imaging (MRI) scans performed at 6 months postoperatively were used to determine the integrity and state of healing. Results There were no significant differences between groups A and B in preoperative VAS, CMS, or ASES scores, and patients in both groups saw significant improvement at each follow-up time point on all 3 outcome scores (P = .001 for all). Scores on all 3 outcome measures were significantly better in group B than group A at each postoperative time point (P < .05 for all). Postoperative MRI scans revealed persistent partial tears in 5 of 18 patients in group A compared with 2 of 22 patients in group B (P < .05). Conversion to full-thickness tear (3/18 patients) was seen only in group A. Conclusion Patients who underwent biological augmentation of their PT-RCTs had improved outcome scores compared with those treated with acromioplasty and debridement alone.

Abstract
BACKGROUND The prevalence of partial-thickness rotator cuff tears (PTRCTs) has been reported to be 13% to 40% within the adult population, accounting for 70% of all rotator cuff tears. Approximately 29% of PTRCTs will progress to full-thickness tears if left untreated. The long-term clinical course after arthroscopic repair of PTRCTs is not well known. PURPOSE To investigate minimum 10-year patient-reported outcomes (PROs) after arthroscopic rotator cuff repair (RCR) of the supraspinatus tendon and to report reoperation and complication rates. STUDY DESIGN Case series; Level of evidence, 4. METHODS Patients were included who underwent arthroscopic RCR of a PTRCT performed by a single surgeon between October 2005 and October 2011. Arthroscopic RCR was performed with a transtendon repair of partial, articular-sided supraspinatus tendon avulsions, bursal-sided repair, or conversion into a full-thickness tear and repair. PRO data were collected preoperatively and at a minimum 10 years postoperatively. PRO measures included the American Shoulder and Elbow Surgeons score, Single Assessment Numeric Evaluation score, the shortened version of Disabilities of the Arm, Shoulder and Hand score (QuickDASH), the 12-Item Short Form Health Survey Physical Component Summary, and patient satisfaction. Subanalyses were performed to determine if tear location or age was associated with outcomes. Retears, revision surgery, and surgical complications were recorded. RESULTS In total, 33 patients (21 men, 12 women) at a mean age of 50 years (range, 23-68) met criteria for inclusion. Follow-up was obtained in 28 (87.5%) of the 32 eligible patients ≥10 years out from surgery (mean, 12 years; range, 10-15 years). Of the 33 PTCRTs, 21 were articular sided and 12 were bursal sided. Of the 33 patients, 26 underwent concomitant biceps tenodesis. At follow-up, the mean PROs were significantly improved when compared with preoperative levels: American Shoulder and Elbow Surgeons score from 67.3 to 93.7 (P < .001), Single Assessment Numeric Evaluation from 70.9 to 91.2 (P = .004), QuickDASH from 22.3 to 6.6 (P < .004), and 12-Item Short Form Health Survey Physical Component Summary from 44.8 to 54.2 (P < .001). Median postoperative satisfaction was 10 (range, 5-10). No patient underwent revision surgery. CONCLUSION Arthroscopic repair of PTRCTs results in excellent clinical outcomes and high patient satisfaction at minimum 10-year follow-up. Furthermore, the procedure is highly durable, with a clinical survivorship rate of 100% at 10 years.

Abstract
Rotator cuff tear including SSP (Supraspinatus) tendon tears are a very common and often painful condition with several therapeutic options such as tendon repair. Reflected by the high retear rates, the preoperative selection of patients suitable for surgery or conservative treatment, which often yields comparable results, remains difficult. Using contrast-enhanced ultrasound (CEUS), it is possible to quantify the SSP muscle perfusion as a surrogate parameter for its vitality and healing capabilities. In this study, we enrolled 20 patients who underwent an SSP repair for a preoperative and two postoperative (6 months and 1 year) clinical and sonographic exams including CEUS. Along with functional improvement (p < 0.001, Constant score), we found a significant increase in CEUS-assessed muscle perfusion after tendon repair (p < 0.001). Furthermore, weak preoperative muscle perfusion was associated with a higher risk of a retear (χ2 = 0.045) and a moderate trend toward lower postoperative shoulder function that did not reach significance (r = 0.435; p = 0.055, DASH score). If confirmed in larger studies, CEUS might be a valuable additional diagnostic method for a precise selection of patients who most likely profit from a tendon repair and those who can be treated conservatively with an equally good outcome.

Abstract
The role of biological augmentation in arthroscopic rotator cuff repair surgery has increased over the years. It has shown favorable healing rates and functional outcomes. Patch augmentation is commonly applied in repairs of massively retracted cuff tears, full-thickness tears, revision repair, or open cuff surgery. There is a paucity of literature on the use of patch augmentation when dealing with a chronic degenerate tendon associated with small-sized cuff tears. In recent years, the resorbable bioinductive bovine collagen implant has gained popularity for its application in partial-thickness tears via an isolated bioinductive repair fashion, without traditional rotator cuff repair. These bioinductive implants, albeit promising in their biological properties for tendon repair, lack structural strength and do not confer similar biomechanical advantages as human dermal allograft. We share our surgical technique for an arthroscopic patch augmentation involving human dermal allograft, using a single-lateral row surgical fixation, to address a degenerate cuff tendon with small-sized rotator cuff tear. We believe that our use of a human dermal patch augmentation conferred increased biomechanical advantage and reduced costs while delivering favorable outcomes for patients in our value-driven care.

Abstract
Background: In large-sized rotator cuff tears, tendon repair with incomplete footprint coverage is performed frequently as a way of tension-free or low-tension repair. Purpose: To compare clinical outcomes after arthroscopic repair of large-sized rotator cuff tears between patients with complete versus incomplete footprint coverage. Study Design: Cohort study; Level of evidence, 3. Methods: Among 297 patients who underwent arthroscopic surgery for a large-sized rotator cuff tear, we selected 58 patients (<50% coverage; mean age, 63.34 ± 6.8 years; 34 men and 24 women) with incomplete footprint coverage. Using propensity score matching, another 58 patients with complete footprint coverage (mean age, 63.4 ± 8.03 years; 34 men and 24 women) were selected after 1:1 matching for age, sex, and tear size—the main demographic and prognostic factors of outcomes after rotator cuff repair. Clinical outcomes were compared on magnetic resonance imaging or ultrasonography at minimum of 6 months postoperatively, and functional outcomes were compared using range of motion and pain visual analog scale; American Shoulder and Elbow Surgeons; Constant; University of California, Los Angeles; and Simple Shoulder Test scores at a minimum of 2 years postoperatively. Results: A total of 18 patients in the incomplete footprint coverage group (31.0%) and 20 patients in the complete footprint coverage group (34.5%) showed healing failure, with no significant difference between groups (P = .843). In addition, there were no differences in functional outcomes between groups (P > .05 for all). Conclusion: Whether the rotator cuff footprint was completely covered did not affect clinical outcomes in conventional arthroscopic repair of large-sized rotator cuff tears.

Abstract
OBJECTIVE To evaluate the influencing factors that affect early pain after arthroscopic rotator cuff repair. METHODS A clinical data of 592 patients who met the selection criteria and underwent arthroscopic rotator cuff repair between June 2018 and October 2020 were retrospectively analyzed. There were 239 males and 353 females, with an average age of 58.1 years (range, 32-81 years). Before operation and at 3 days, 6 weeks, and 3 months after operation, the pain degree of patients was evaluated by visual analogue scale (VAS) score; and the patients were divided into no pain or mild pain group and moderate to severe pain group according to the postoperative VAS score. Preoperative and intraoperative related factors were included for univariate analysis, including age, gender, body mass index, preoperative VAS score, history of frozen shoulder, history of hypertension, history of diabetes, history of smoking, affected tendons (supraspinatus, infraspinatus, or subscapularis tendon injury), supraspinatus muscle atrophy, fatty infiltration, operation time, degree of rotator cuff tear, number of anchors, and whether to perform acromioplasty. The influencing factors of postoperative pain were screened; further logistic regression was used to conduct multivariate analysis to screen for risk factors. RESULTS Moderate to severe pain occurred in 440 patients (74.3%) at 3 days after operation, 382 patients (66.2%) at 6 weeks, and 141 patients (23.8%) at 3 months. Multivariate analysis showed that the women, partial-thickness rotator cuff tear, and acromioplasty were risk factors for pain at 3 days after operation ( P<0.05); the women, combined with fatty infiltration, partial-thickness rotator cuff tear, and acromioplasty were the risk factors at 6 weeks ( P<0.05); and the women, combined with fatty infiltration, and partial-thickness rotator cuff tear were risk factors at 3 months ( P<0.05). CONCLUSION Among patients undergoing arthroscopic rotator cuff repair, women, those with smaller rotator cuff tears, combined with fatty infiltration, and acromioplasty have more severe pain within 3 months after operation, and attention should be paid to postoperative analgesia in these patients management, providing an individualized approach to rehabilitation, and closer follow-up.

Abstract
PURPOSE Post-operative shoulder stiffness (SS) is a common complication after arthroscopic rotator cuff (RC) repair. The aim of this prospective study is to evaluate the role of surgical risk factors in the development of this complication, with special focus on the characteristics of the RC tears. METHODS Two-hundred and twenty patients who underwent arthroscopic RC repair for degenerative posterosuperior RC tears were included. Surgery-related risk factors for development of post-operative SS belonging to the following five categories were documented and analyzed: previous surgery, RC tear characteristics, hardware and repair type, concomitant procedures, time and duration of surgery. The incidence of post-operative SS was evaluated according to the criteria described by Brislin and colleagues. RESULTS The incidence of post-operative SS was 8.64%. The treatment of partial lesions by tear completion and repair technique was significantly associated with development of post-operative SS (p = 0.0083, pc = 0.04). A multivariate analysis revealed that treatment of partial lesions in patients younger than 60 years was associated to a higher risk of developing post-operative SS (p = 0.007). Previously known pre-operative risk factors such as female sex and younger age were confirmed. No other significant associations were documented. CONCLUSION The treatment of partial lesions of the RC may lead to a higher risk of post-operative SS than the treatment of complete lesions, in particular in patients younger than 60 years. Possible explanations of this finding are the increased release of pro-inflammatory cytokines caused by the additional surgical trauma needed to complete the lesion and the different pain perception of the subgroup of patients who require surgical treatment already for partial tears. EVIDENCE A higher risk of post-operative SS should be expected after tear completion and repair of partial lesions, especially in young patients. Appropriate pre-operative counseling and post-operative rehabilitation should be considered when approaching this subgroup of RC tears. LEVEL OF EVIDENCE Prognostic study, level II.

Abstract
Objective: To perform a comparative analysis of the results of arthroscopic surgical treatment of partial and complete rotator cuff (RC) injuries. Methods: Eighty-four shoulders with partial or complete RC tear that underwent arthroscopic repair were retrospectively evaluated using UCLA and Constant scores, assessment of strength, and range of motion. Fifty-seven shoulders with complete injuries and 27 with partial injuries were identified. Results: Age (p = 0.007) was higher in those with complete lesions (mean 61.4 ± 7.9 years), compared to those with partial lesions (mean 56.5 ± 7.1 years). The complete injuries group showed a higher elevation difference in relation to the contralateral shoulder compared to the partial injuries group (partial injuries: −1.1% vs complete injuries: −16.5%), statistically significant difference (p = 0.0004). In addition, complete lesions presented 96.5% of excellent and good results and a median of 35 in the UCLA score and partial lesions presented 84.6% of good/ excellent results and a median of 34. The Constant score showed 91.2% of satisfactory results in complete lesions and 77% in partial ones. Conclusion: Arthroscopic repair shows satisfactory functional results for both partial and complete rotator cuff injuries, with similar outcomes between groups.

Abstract
Partial thickness rotator cuff tears (PRCTs) are a challenging disease entity. Optimal management of PRCTs continues to be controversial. Although advances in magnetic resonance imaging and ultrasonography have aided in early diagnosis, arthroscopic evaluation remains the benchmark for diagnosis. Conservative treatment is often the first line of management for most patients; however, evidence suggests that surgical intervention may limit tear progression and the long-term sequelae. Surgical decision making is driven by factors such as age, arm dominance, etiology, activity level, tear thickness, and tear location. Many surgical options have been described in the literature to treat PRCTs including arthroscopic débridement, transosseous, in situ repair techniques, and tear completion and repair. Biologic supplements have also become an attractive alternative to aid in healing; however, the long-term efficacy of these modalities is largely unknown. This article will provide a detailed review of the etiology and natural history of PRCTs, as well as diagnosis, and current management to guide clinical decision-making and formulate an algorithm for management of PRCTs for the orthopaedic surgeon.

Abstract
Purpose The purpose of this study was to prospectively collect safety and efficacy data in a large group of patients undergoing arthroscopic repair of full-thickness rotator cuff tears augmented with a resorbable bioinductive bovine collagen implant designed to promote healing. Methods Seventeen centers across the United States enrolled patients in an institutional review board-approved registry to collect outcomes data on the implant. Patients undergoing surgical management of full-thickness rotator cuff tears augmented with the implant were enrolled. Inclusion criteria were age of ≥21 years, willingness to participate and the ability to read and speak English. Exclusion criteria included hypersensitivity to bovine-derived products. Patients were assessed before and after surgery at up to 1 year with outcomes including the single-assessment numeric evaluation (SANE), Veterans RAND 12-Item (VR-12) mental components and physical components (VR-12 PCS), American Shoulder and Elbow Surgeons (ASES), and Western Ontario Rotator Cuff (WORC) outcome measures. Ad hoc analyses were performed to compare these outcomes at all time points depending on tear size (small/medium vs large/massive). Serious complications were collected. Results Of 210 patients enrolled, 192 had 1-year follow-up data available. The patients experienced statistically significant improvement between baseline and 1 year for mean SANE, VR-12 PCS, ASES, and WORC scores (40.0-82.0, 33.5-47.3, 46.2-87.8, and 36.2-81.0, respectively; P < .001 for all results). Ad-hoc analysis demonstrated that similar results were obtained at 1 year regardless of tear size. Twenty patients (10.4%) experienced serious complications (10.4%), including revision surgery (n = 18), proximal humerus fracture/partial subscapularis tear resulting from multiple falls (n = 1), and adhesive capsulitis (n = 1). Conclusions The safety and efficacy of a bioinductive implant in the surgical management of full-thickness rotator cuff tears at 1 year was shown in this study. Implant efficacy appears to be comparable regardless of the underlying tear size. Level of Evidence Level IV, therapeutic case series.

Abstract
Objective To compare the effects of arthroscopic debridement and repair in treating Ellman grade II bursal‐side partial‐thickness rotator cuff tears. Methods This is a single‐center, prospective, randomized controlled trial. From September 2017 to April 2019, 78 patients underwent arthroscopic debridement (35 patients) or repair (43 patients) due to Ellman grade II bursal‐side partial‐thickness rotator cuff tears. Twenty‐six men and 52 women were included in the study, with an average age of 56.31 years (range, 42 to 74 years). After the acromioplasty was formed, the debridement group only performed stump refreshing and surrounding soft tissue cleaning, while the repair group converted the partial tears into full‐thickness tears and then sutured them by single row or suture bridge technique. The visual analogue scale (VAS), Constant‐Murley shoulder (CMS), American Shoulder and Elbow Surgeons (ASES), and University of California, Los Angeles (UCLA) scores were used to evaluate clinical results preoperatively and at 6, 12, and 18 months postoperatively. Magnetic resonance imaging was used to assess the integrity of the rotator cuff, muscle atrophy, and fat infiltration. Results A total of 85 patients met the inclusion criteria and were randomly divided into the debridement group (41 patients) and the repair group (43 patients). During the 18‐month follow‐up period, a total of seven patients were lost to follow‐up. The functional scores of both groups were significantly improved: the VAS score decreased 5.06 and 4.63 in the debridement group (5.77 preoperative to 0.71 postoperative) and the repair group (5.49 to 0.86) (P < 0.05). Moreover, the CMS, ASES, UCLA scores increased 51.63, 58.24, 20.57 in debridement group (39.46 to 91.09, 34.14 to 92.38, 13.29 to 33.86), and increased 48.14, 60.53, 20.93 in repair group (43.63 to 91.77, 33.10 to 93.63, 12.58 to 33.51) (P < 0.05). No significant differences were found in functional scores between the two groups at 6, 12, and 18 months postoperatively (P > 0.05). The magnetic resonance imaging showed no re‐tears, and no difference was observed in the degree of muscle atrophy and fat infiltration between the two groups (P > 0.05). Except for four cases of shoulder stiffness, no other obvious surgery‐related complications were found. Conclusion For Ellman grade II bursal‐side partial‐thickness rotator cuff tears, both the debridement and repair groups achieved good results during 18‐month follow‐ups, with no difference between the two groups.

Abstract
Background: Surgical treatment of partial-thickness rotator cuff tears remains challenging and controversial, with several traditional options including debridement with acromioplasty, transtendon or in situ repair, and take-down and repair. A resorbable bioinductive bovine collagen implant has shown promise as an alternative treatment option for partial-thickness tears. Purpose: Data from a registry were analyzed to further establish that the implant contributes to improved patient-reported outcome (PRO) scores across a large number of patients treated for partial-thickness rotator cuff tears. Study Design: Case series; Level of evidence, 4. Methods: A total of 19 centers in the United States enrolled patients >21 years old with partial-thickness tears of the rotator cuff in a comprehensive prospective multicenter registry. PRO scores were recorded preoperatively and postoperatively at 2 and 6 weeks, 3 and 6 months, and 1 year: American Shoulder and Elbow Surgeons, Single Assessment Numeric Evaluation, Veterans RAND 12-Item Health Survey (physical and mental component scores), and Western Ontario Rotator Cuff scores. Revisions were reported throughout the study. Results: The registry included 272 patients with partial-thickness tears (49 grade 1 tears, 101 grade 2 tears, and 122 grade 3 tears), 241 who underwent isolated bioinductive repair (IBR; collagen implant placed after bursectomy without a traditional rotator cuff repair), and 31 who had take-down and repair with bioinductive augmentation. Patients experienced statistically significant and sustained improvement from baseline for all PRO scores beginning at 3 months. Among patients with grade ≥2 tears, those with take-down and repair had significantly inferior scores at 2 and 6 weeks for most PRO scores as compared with those who underwent IBR, but the difference was no longer significant at 1 year for all but the physical component score of the Veterans RAND 12-Item Health Survey. There were 11 revisions, which occurred at a mean ± SD of 188.7 ± 88.0 days after the index surgery. There were no infections. Conclusion: This registry analysis further establishes across a large data set that this resorbable bioinductive bovine collagen implant improves PROs in all grades of partial-thickness tears, whether used as IBR or in conjunction with take-down and repair. IBR may offer improved early clinical outcomes (≤6 weeks) and comparable outcomes at 1 year when compared with a more invasive “take-down and repair” approach.

Abstract
BACKGROUND Current surgical treatment options for partial-thickness tears (eg, takedown and repair, in situ repair) are limited by the degenerative nature of the underlying tendon and may require extensive intervention that can alter the anatomic footprint. The complexity of available techniques to address these issues led to the development of a resorbable collagen implant, which can be used to create a bioinductive repair of partial-thickness tears. METHODS We prospectively enrolled 33 patients with chronic, degenerative, intermediate-grade (n = 12), or high-grade (n = 21) partial-thickness tears (11 articular, 10 bursal, 4 intrasubstance, and 8 hybrid) of the supraspinatus tendon in a multicenter study. After arthroscopic subacromial decompression without a traditional rotator cuff repair, a bioinductive implant was secured over the bursal surface of the tendon. Clinical outcomes were assessed using American Shoulder and Elbow Surgeons (ASES) and Constant-Murley scores (CMS) preoperatively and at 3 months, 1 year, and 2 years postoperatively. Magnetic resonance imaging was performed to assess postoperative tendon healing and thickness at the original tear site. RESULTS At 2-year follow-up, mean ASES and CMS scores improved both clinically and statistically at 1 and 2 years, compared with baseline, for intermediate- and high-grade tears. There was magnetic resonance imaging evidence of new tissue fill-in within the original baseline tear in 100% of the intermediate-grade tears and 95% of the high-grade tears. In 90.9% of the intermediate-grade tears and 84.2% of the high-grade tears, this new tissue fill-in represented at least an additional 50% of the volume of the initial lesion. From baseline to 2-year follow-up, the mean tendon thickness increased by 1.2 mm (standard deviation, 1.3; P = .012) and 1.8 mm (standard deviation, 2.2; P = .003) in the intermediate- and high-grade tears, respectively. The analysis of tear grade and location revealed no statistically significant difference in the change in mean tendon thickness at any time point. One patient with a high-grade articular lesion demonstrated progression to a full-thickness tear; however, the patient was noncompliant and the injury occurred while shoveling snow 1 month after surgery. Neither tear location nor treatment of bicep pathology affected the ASES or CMS scores at any follow-up point. No serious adverse events related to the implant were reported. CONCLUSION Final results from this 2-year prospective study indicate that the use of this resorbable bovine collagen implant for isolated bioinductive repair of intermediate- and high-grade partial-thickness rotator cuff tears of the supraspinatus is safe and effective, regardless of tear grade and location.

Abstract
PURPOSE The purpose was to evaluate the clinical and radiological results of knotless repair with flat-braided suture in full small-sized supraspinatus tendon tears (< 1 cm). METHODS A consecutive series of 54 patients with isolated small supraspinatus tendon tear (< 1 cm and Goutallier index < 2) was evaluated in the study. Patients underwent a knotless arthroscopic repair using flat-braided suture (2 mm wide). Minimal follow-up required was 5 years. Changes in Murley-Constant score, ASES score, strength, and pain relief were assessed. The Sugaya score was used to confirm the tendon repair on MRI. Data were analyzed in two subgroups: technique with additional U point for dog ear deformity (group 1) and technique without additional U point (group 2). The immobilization period was 3 weeks long. Passive mobilization was immediate. RESULTS Fifty-four patients were included. Mean age was 57 ± 4 years. The average follow-up was 68 ± 10 months. Average preoperative score of Constant was 51.2 ± 8.5 and 83.1 ± 14.6 at the end of the follow-up (p < 0.001). Mean VAS went from 5.8 ± 1.8 to 1.9 ± 2.1 (p < 0.001). Average forward elevation of the shoulder went from 86.3° ± 9 preoperatively to 169.6° ± 15.9 at the end of the follow-up (p < 0.001). The strength score was significantly higher post-operatively (18.4 vs. 8.3, p < 0.001.). The ASES score was significantly improved 49.1 ± 13.1 vs. 88.6 ± 15.8, p < 0.001). The MRI assessment revealed 94% of Sugaya 1-2. No significant difference was observed between group 1 and 2 regarding all clinical outcomes. Two complex regional pain syndromes were described with a favorable evolution. Three patients presented a retear requiring an iterative arthroscopic repair. CONCLUSION The use of a knotless arthroscopic construct with flat-braided suture for small supraspinatus repair achieved excellent structural and clinical results. This technique is fully adequate for the arthroscopic treatment of such tears, enabling early mobilization. LEVEL OF EVIDENCE Level III.

Purpose To assess the mechanical properties, tendon resistance to suture cutout, and knot size of a broad variety of high-strength sutures and tapes available for arthroscopic rotator cuff repair. Methods Nine different types of high-strength sutures and tapes for arthroscopic rotator cuff repair were studied: 6 were tapes (FiberTape, Hi-Fi Tape, Permatape, SutureTape, UltraTape, and XBraid TT), and 3 were sutures (Dynacord, FiberWire, and Ultrabraid). First, mechanical tensile testing of suture loops (n = 6) was performed. Second, the suture material was passed through an intact human cadaveric rotator cuff tendon (supraspinatus or infraspinatus), and cyclic as well as load-to-failure testing was performed, 8 times for each suture or tape. Statistical analysis of groups (tapes vs sutures) and between each suture and each tape was performed. Results Material testing revealed significant differences with superior mechanical properties of tapes compared with sutures regarding load for 3 mm of displacement (201 N vs 84 N, P < .0001), displacement at 200 N (3.6 mm vs 6.6 mm, P < .0001), stiffness (46 N/mm vs 25 N/mm, P < .0001), and ultimate load to failure (509 N vs 288 N, P < .0001). FiberTape showed the highest ultimate load to failure (805.5 ± 36.1 N), the highest load necessary for 3 mm of displacement (376.2 ± 19.1 N), and the lowest displacement at a 200-N load (2 ± 0.1 mm). Permatape had the highest stiffness (58.5 ± 5.3 N/mm). FiberTape had the highest knot height (9.5 ± 1.3 mm) and knot width (3.8 ± 0.7 mm) of a suture loop with 7 square knots. The typical failure mode in the cadaveric study part was tendon cut through. Conclusions Biomechanical in vitro testing showed that high-strength suture tapes compared with regular high-strength sutures have significantly better mechanical properties in both dry-laboratory testing and human cadaveric rotator cuff tendon pullout testing. FiberTape outperformed the other tapes and the sutures used in this analysis. Nonetheless, differences in tendon testing appeared to be less substantial than in dry-laboratory testing, and FiberTape had the highest knot height and width. Clinical Relevance FiberTape revealed the most favorable biomechanical performance in dry-laboratory and rotator cuff tendon testing. It may provide the best repair strength in vivo; however, it also has the largest knot size.

Abstract
PURPOSE Osteoarthritis (OA) in the glenohumeral joint is a concomitant lesion with rotator cuff tear that commonly occurs in older patients. The authors aimed to evaluate the effect of associated OA on the treatment outcome of rotator cuff repair. METHODS A total of three hundred and forty-eight patients who underwent full-thickness arthroscopic rotator cuff repair were retrospectively reviewed, and the data were prospectively collected. The severity of OA was evaluated using the Samilson and Prieto method preoperatively and the Outerbridge classification intraoperatively. The patients were divided into the small-to-medium group and large-to-massive group according to rotator cuff tear size and were evaluated for presence or absence of OA. The postoperative clinical outcomes were assessed using the visual analog scale for pain, simple shoulder test (SST), University of California-Los Angeles, Constant, and American Shoulder and Elbow Surgeons (ASES) scoring systems at baseline and at final follow-up. RESULTS Forty-five patients were diagnosed with glenohumeral OA (12.9%). Overall, no significant differences were observed in demographic and baseline data between the two groups according to the presence or absence of OA. The clinical symptoms of both groups significantly improved at the final follow-up. At the final follow-up, no significant differences were found in the VAS for pain, SST, UCLA, Constant, and ASES scores between the two groups. In the large-to-massive tear group, patients with OA had significantly inferior clinical results compared with those without OA. CONCLUSION The clinical outcome scores improved after rotator cuff repair regardless of the presence of concomitant OA. However, glenohumeral OA should be considered as a potential negative prognostic factor in patients with large-to-massive rotator cuff tears. LEVEL OF EVIDENCE III.

Abstract
Background and Objectives: Different arthroscopic procedures are used for partial-thickness rotator cuff tears (PT-RCTs), but there is still no evidence on the superiority of one procedure over the other. The aim of this study was to evaluate the clinical outcomes and the rate of complications of a tear completion repair (TCR) technique. Materials and Methods: Patients who had undergone arthroscopic TCR technique for PT-RCTs with a follow-up of at least 2-years after surgery were included. The TCR technique involved the removal of the "critical zone" and creating microfractures to biologically support tendon healing. Functional outcomes were assessed prospectively by the Constant score (CS) and active and passive range of movement (ROM). Pain and patient satisfaction were measured using a visual analog scale (VAS). Complication rates were recorded, and tendon integrity was assessed with magnetic resonance imaging (MRI) or ultrasound performed at least 2-years after surgery. Results: Eighty-seven patients with a median age of 57 years were followed-up for a median of 5 years. The CS score improved from 53.5 preoperatively to 94.0 postoperatively (p < 0.001). Median VAS score decreased from 8.6 to 1.0 (p < 0.0001). Median patient satisfaction was 9.3. The overall complication rate was 14.9%. Conclusions: Patients with PT-RCTs of the supraspinatus tendon treated by the TCR technique with "critical zone" removal and biological stimulation by microfractures showed good functional results with excellent strength recovery, a high degree of patient satisfaction, and resolution of painful symptoms at mid-term follow-up.

Abstract
PURPOSE The effect of smoking on preoperative and postoperative outcome scores as well as quality of life measurements after arthroscopic rotator cuff repair (ARCR) has not been fully understood, and studies regarding this are lacking in the literature. This study aimed to evaluate the effect of smoking on function and quality of life after ARCR. METHODS Two-hundred patients who underwent full-thickness ARCR with a minimum 1-year follow-up period were included and evaluated retrospectively. The patients were divided into two groups: smokers (Group 1, 59 patients) and nonsmokers (Group 2, 141 patients). Pre- and postoperative Constant Murley (CM) scores, American Shoulder and Elbow Surgeons (ASES) scores, visual analogue scale scores (VASs), and Short-Form 36 health survey (SF-36) scores were used to evaluate functional and quality of life outcomes. The correlation between the smoking amount (pack-years) and outcomes was evaluated. RESULTS A total of 200 patients included into study (90 male and 110 female) with mean age of 62.68 ± 3.98. There was no statistically significant difference between the two groups regarding preoperative scores, except in the ASES score (P = 0.021 ) Additionally, there was a statistically significant difference between the groups regarding postoperative CM score, ASES score, and VAS, and in physical functioning and role limitations due to physical health domains of the SF-36 (P = 0.029, P = 0.038, P = 0.021 and P = 0.020, respectively). There were small to moderate negative correlations between amount of smoking and preoperative physical functioning, role limitations from emotional problems, energy/fatigue, emotional well-being, and pain domains of the SF-36. However, there were moderate to strong negative correlations between amount of smoking and postoperative SF-36 domains. CONCLUSION Preoperative and postoperative functional outcome scores, and quality of life measurements are negatively affected from smoking. As the amount of smoking increases, postoperative results are negatively affected. LEVEL OF EVIDENCE 3.

Abstract
Objective To investigate the effect of unilateral rotator cuff repair on the contralateral shoulder in patients with bilateral rotator cuff tears. Methods A clinical data of 46 patients with bilateral rotator cuff tears met the criteria between May 2016 and May 2019 was retrospectively analyzed. Of 46 patients, 23 patients underwent bilateral conservative treatment (conservation group), 23 patients underwent unilateral arthroscopic rotator cuff repair, and conservative treatment on the contralateral side (operation group). There was no significant difference in gender, age, disease duration, degree of rotator cuff tear, and comorbidities between 2 groups ( P>0.05). Before operation and at 6 and 12 months after operation, the degree of the rotator cuff tear was measured by MRI, and the shoulder function was evaluated by the visual analogue scale (VAS) score, University of California Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and range of motion (ROM) (forward flexion, external rotation, external rotation at 90° of abduction, and internal rotation). The evaluation results of the non-surgical side of shoulders in the operation group were compared with one side of shoulders in the conservation group. Results All incisions healed by first intention without any complication after operation. All patients were followed up 12 months. MRI reexamination showed that the degree of rotator cuff tear of the contralateral shoulder in the operation group increased significantly after operation ( P<0.05). There was no significant difference between the operation group and the conservation group before operation ( P>0.05), but the rotator cuff tear of the contralateral shoulder in the operation group was more serious than that of the conservation group at 6 and 12 months after operation ( P<0.05). At 6 and 12 months after operation, the VAS score, UCLA score, and ASES score significantly improved when compared with the preoperative scores in 2 groups ( P<0.05). There was no significant difference in the VAS score, UCLA score, and ASES score between 2 groups before operation ( P>0.05). The function scores in the conservation group were better than those in the operation group at 6 and 12 months after operation ( P<0.05). There were significant differences in the ROM of shoulder between pre- and post-operation in 2 groups ( P<0.05). And there was no significant difference between 2 groups at pre- and post-operation ( P>0.05). Conclusion For patients with bilateral rotator cuff tears, the unilateral rotator cuff repair can aggravate the rotator cuff tear of contralateral shoulder.

Abstract
Background: Arthroscopic rotator cuff repair can be quite complex and time consuming, particularly early in the surgeon’s learning curve. Hypothesis: Patients who have undergone rotator cuff repair with shorter operative times will be less likely to have a rotator cuff retear at 6 months postoperatively. Study Design: Case-control study; Level of evidence, 3. Methods: This study was an analysis of data from 1600 consecutive patients (670 partial-thickness and 930 full-thickness tears) who had rotator cuff repair performed by a single surgeon utilizing an arthroscopic, single-row, knotless inverted mattress suture anchor technique. All patients underwent ultrasound at 6 months postoperatively to determine repair integrity. Moving average analysis was performed for the variables of operative time and case number to evaluate the surgeon’s learning curve. Results: For early cases, the mean operative time was approximately 35 minutes. After approximately 450 cases, the operative time plateaued at approximately 20 minutes. The mean operative time for the cohort (±SEM) was 22 ± 0.3 minutes, and the mean retear rate was 13%. Increased operative time was associated with a retear (r = 0.18; P < .001). Multiple logistic regression analysis revealed that the variables with the most independent effect on retears were larger tear size (Wald statistic = 36; P < .001), lower case number (ie, less surgeon experience) (Wald statistic = 28; P < .001), older patient age (Wald statistic = 23; P < .001), full-thickness tears (Wald statistic = 13; P < .001), and lower surgeon-rated repair quality (Wald statistic = 8; P = .004). Operative time was not a significant independent factor contributing to retears. Conclusion: Operative time and rotator cuff retear rates decreased as surgical team experience increased. The hypothesis of this study, however, was not supported. The reduced retear rate was not related to a reduction in operative time per se but rather to improved surgical team experience and patient factors, such as improved healing with smaller tears in younger patients.

Abstract
HYPOTHESIS We aimed to report the clinical outcomes of arthroscopic débridement vs. repair for Ellman grade II bursal-side partial-thickness rotator cuff tears. METHODS Patients who presented with Ellman grade II bursal-side partial-thickness rotator cuff tears from September 2015 to August 2017 were included. On the basis of preoperative findings and patient preference, 20 patients underwent débridement whereas 26 underwent arthroscopic repair. The visual analog scale (VAS), Constant-Murley shoulder, American Shoulder and Elbow Surgeons, and University of California-Los Angeles scores were assessed. Magnetic resonance imaging and B-mode ultrasonography were performed preoperatively and at 6, 12, and 24 months postoperatively. RESULTS All 46 patients were available throughout follow-up. At 2 years postoperatively, the VAS score had improved from 6.42 ± 1.56 to 0.65 ± 0.51 in the débridement group and from 6.26 ± 1.32 to 0.75 ± 0.42 in the repair group. The VAS score differed significantly between the 2 groups at 6 months postoperatively. All patient-reported outcomes improved in both groups. The American Shoulder and Elbow Surgeons score (P = .009), Constant-Murley shoulder score (P = .014), and University of California-Los Angeles score (P = .030) differed significantly between the 2 groups (higher in the débridement group) at 6 months postoperatively. Finally, 44 patients having intact tendon repairs with no interval worsening of partial-thickness tears underwent postoperative scheduled magnetic resonance imaging and B-mode ultrasonography examinations. CONCLUSION Arthroscopic débridement and repair of Ellman grade II bursal-side partial-thickness rotator cuff tears achieved comparable clinical scores and low retear rates during 2 years of follow-up. However, débridement achieved better results, especially within 6 months postoperatively, and achieved a favorable prognosis up to 2 years postoperatively.

Abstract
PURPOSE OF THE REVIEW To discuss tear- and patient-related factors that influence the healing potential of rotator cuff tears and to clarify the terminology surrounding this topic. RECENT FINDINGS Over the last few years, further insight has been gained regarding rotator cuff tear features that are associated with poor healing rates after rotator cuff repair. Some of these features have been incorporated in prediction models developed to accurately predict rotator cuff healing rates utilizing preoperative risk factors weighted by importance. Rotator cuff tears may be considered functionally irreparable based on their size, chronicity, absence of adequate tendon length, atrophy, and fatty infiltration. Furthermore, advanced age, use of tobacco products, diabetes, and other patient-related factors may impair tendon healing. Careful analysis and discussion of all these factors with patients is essential to determine if surgical repair of a rotator cuff tear should be recommended, or if it is best to proceed with one of the several salvage procedures reviewed in this topical collection, including augmentation of the repair, superior capsular reconstruction, tendon transfers, and other.

Abstract
BACKGROUND Arthroscopic rotator cuff repair (ARCR) is one of the most commonly performed orthopaedic surgical procedures; however, patient-reported outcomes have varied greatly in the literature. PURPOSE To identify preoperative factors that affect outcomes and to develop prognostic tools for predicting functional outcomes in future ARCR cases. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients were included who underwent ARCR for repairable full-thickness rotator cuff tears with at least 2 years of follow-up. Twelve predictors were entered as candidate predictors in each model: age, sex, workers' compensation (WC) status, previous cuff repair, tear size, tear shape, multiple-tendon involvement, tendon stump length, Goutallier classification, critical shoulder angle, length of follow-up, and baseline subjective outcomes score. Postoperative American Shoulder and Elbow Surgeons (ASES), 12-Item Short Form Health Survey Physical Component Summary (SF-12 PCS), QuickDASH (short version of Disabilities of the Arm, Shoulder and Hand), and patient satisfaction were each modeled through proportional odds ordinal logistic regression. Model results were presented with marginal covariate effect plots and predictive nomograms. RESULTS Overall, 552 shoulders fit inclusion criteria. The mean age at surgery was 60.2 years (range, 23-81 years). Twenty-five (4.5%) shoulders underwent revision cuff repair or reverse arthroplasty at a mean 1.9 years (range, 0.1-7.9 years) postoperatively. Overall, 509 shoulders were eligible for follow-up, and minimum 2-year postoperative patient-reported outcomes were obtained for 449 (88.2%) at a mean 4.8 years (range, 2-11 years). The ASES score demonstrated significant improvement from pre- to postoperative median (interquartile range): 58 (44.9-71.6) to 98.3 (89.9-100; P < .001). Women demonstrated significantly higher 2-year reoperation rates than men (5.8% vs 1.6%; odds ratio, 2.8 [95% CI, 0.73-9.6]; P = .023). Independently significant predictors for lower postoperative ASES scores included previous ARCR (P < .001), female sex (P < .001), and a WC claim (P < .001). Significant predictors for worse QuickDASH scores included WC claim (P < .001), female sex (P < .001), previous ARCR (P = .007), and ≥7 years of follow-up time. Significant predictors for lower SF-12 PCS scores included WC claim (P < .001), female sex (P = .001), and lower baseline SF-12 PCS. Last, significant independent predictors of patient satisfaction included previous ARCR (P = .004), WC claim (P = .011), female sex (P = .041), and age (P = .041). CONCLUSION Excellent clinical outcomes and low failure rates were obtained after ARCR by using careful patient selection and modern surgical techniques for ARCR. Female sex, WC claim, and previous ARCR were significant predictors of poorer outcomes in at least 3 patient-reported outcome models. Prognostic nomograms were developed to aid in future patient selection, clinical decision making, and patient education.

Abstract
Supraspinatus (SSP) tendon tears represent a common indication for shoulder surgery. Yet, prediction of postoperative function and tendon retear remains challenging and primarily relies on morphologic magnetic resonance imaging (MRI)-based parameters, supported by patients' demographic data like age, gender, and comorbidities. Considering continuously high retear rates, especially in patients with larger tears and negative prognostic factors, improved outcome prediction could be of high clinical value. Contrast-enhanced ultrasound (CEUS) enables an assessment of dynamic perfusion of the SSP muscle. As a potential surrogate for muscle vitality, CEUS might reflect functional properties of the SSP and support improved outcome prediction after tendon repair. Fifty patients with isolated SSP tendon tears were prospectively enrolled. Preoperatively, SSP muscle perfusion was quantified by CEUS and conventional morphologic parameters like tear size, fatty infiltration, and tendon retraction were assessed by MRI. At six months follow-up, shoulder function, tendon integrity, and muscle perfusion were reassessed. The predictive value of preoperative CEUS for postoperative shoulder function and tendon integrity was evaluated. 35 patients entered the statistical analysis. Preoperative CEUS-based assessment of SSP perfusion significantly correlated with early postoperative shoulder function (Constant, r = 0.48, p < 0.018) and tendon retear (r = 0.67, p < 0.001). CEUS-based subgroup analysis identified patients with exceptionally high, respectively low risk for tendon retear. CEUS-based assessment of the SSP seemed to predict early shoulder function and tendon retear after SSP repair and allowed to identify patient subgroups with exceptionally high or low risk for tendon retear. © 2019 The Authors.

Abstract
PURPOSE The purpose of this study was to investigate the clinical results of arthroscopic rotator cuff repair in patients with anterior greater tubercle cyst in magnetic resonance imaging (MRI). METHODS The cyst-present group comprised 38 patients with anterior greater tubercle cyst in MRI, and age- and sex-matched 30 patients without cyst in humeral head were included in the control group. The cystic group was divided into two groups, smaller than 5 mm (21 patients) and larger than 5 mm (17 patients), according to the cyst size. A total of three groups were created. In the evaluation of clinical outcomes, modified University of California at Los Angeles (UCLA) and the Western Ontario Rotator Cuff Index (WORC) were used. The visual analog scale (VAS) was used to assess pain. One-way analysis of variance was used to compare VAS, UCLA, and WORC scores among the groups. RESULTS There was a statistically significant difference in the clinical results of VAS, UCLA, and WORC among the cystic and noncystic groups in the anterior greater tubercle ( p < 0.05). There was also a statistically significant difference in the clinical results of UCLA, WORC, and VAS scores according to the cyst sizes in the anterior greater tubercle cyst group ( p < 0.05). CONCLUSION Anterior greater tubercle cysts have negative effects on rotator cuff repair results. If the anterior greater tubercle cyst size is greater than 5 mm, the negative effects of rotator cuff repair results are more pronounced. An understanding of anterior greater tubercle cysts has a critical importance for rotator cuff surgery planning.

Abstract
Background Rotator cuff repair is one of the most common surgical procedures performed on the shoulder. Previous studies have indicated that pain and disability can vary significantly between patients with similarly appearing rotator cuff tears on diagnostic imaging. Prior literature has compared functional outcomes between operative and nonoperative treatments as well as variability in surgical techniques. However, few studies have examined postoperative outcomes based on patient factors such as sex. Purpose To compare patient-reported outcomes after rotator cuff repair between men and women. Study Design Cohort study; Level of evidence, 2. Methods A total of 283 patients (153 male, 130 female) who underwent primary arthroscopic rotator cuff repair were included in this study; of those, 275 patients (97.2%) completed 1-year follow-up. Patient-reported pain visual analog scale (VAS), Veterans RAND 12-item Health Survey (VR-12 mental and physical components), American Shoulder and Elbow Surgeons (ASES), and Single Assessment Numeric Evaluation (SANE) scores were collected preoperatively and at 2 weeks, 6 weeks, 3 months, 6 months, and 1 year postoperatively using an electronic outcomes system. Results Women reported higher VAS pain scores when compared with men preoperatively (P < .01) and at 2 weeks (P < .01), 6 weeks (P < .01), and 3 months (P = .02) postoperatively. Additionally, women experienced a greater overall change in the mean VAS score preoperatively when compared with 1 year postoperatively (P < .01). The use of narcotic pain medication 2 weeks after surgery was greater in women (P = .032). Women had significantly lower preoperative VR-12 mental scores (P = .03) and experienced a greater increase in the mean VR-12 mental score preoperatively when compared with 1 year postoperatively (P < .01). Men had higher ASES scores preoperatively (P < .01) and at 3 months postoperatively (P < .01). Women experienced a greater overall change in the ASES score preoperatively when compared with 1 year postoperatively (P < .01). Conclusion Women reported greater pain and decreased shoulder function compared with men during the initial 3 months after arthroscopic rotator cuff repair. There were no sex-based differences in patient-reported outcomes at 1-year follow-up. The results of this study indicate that there are sex-related differences in the early postoperative recovery of patients undergoing rotator cuff repair, contributing to postoperative expectations for both clinicians and patients alike.

Abstract
PURPOSE We compared preoperative and postoperative measures among workers' compensation board (WCB) recipients and non-recipients and determined the impact of WCB receipt on the 1- and 2-year outcomes of rotator cuff repair. METHODS We retrospectively reviewed patients with full-thickness rotator cuff tears who underwent arthroscopic repair between September 2011 and September 2014. Patients were divided into two groups based on WCB status: WCB recipients and non-recipients. All patients returned for follow-up functional evaluations at 1 and 2 years after the operation. Four outcome measures were evaluated: visual analog scale (VAS) pain score, American Shoulder and Elbow Surgeons (ASES) score, the Shoulder Rating Scale of the University of California at Los Angeles (UCLA), and range of motion (ROM). RESULTS Seventy patients (38 males, 32 females) were evaluated, 20 of whom were WCB recipients. At 1 year after the operation, ASES, UCLA, and VAS scores as well as abduction ROM (Abd-ROM) had improved significantly in both groups. However, non-recipients showed significantly greater improvement than did WCB recipients in ASES, UCLA, and VAS scores and in forward flexion ROM and Abd-ROM ( p = 0.000, 0.009, 0.002, 0.046, and 0.020, respectively). However, at 2 years after the operation (after the end of WCB), there were no significant differences in any clinical outcome between WCB recipients and non-recipients ( p = 0.057, 0.106, 0.075, 0.724, and 0.787, respectively). CONCLUSION Although workers' compensation recipients who underwent arthroscopic rotator cuff repair had worse outcomes while receiving WCB benefits, the outcomes were similar after WCB benefits ended.

Abstract
BACKGROUND Fatty infiltration of the rotator cuff musculature increases in larger tears and is a factor in retearing. However, tearing may recur even in patients with small original tears and little fatty infiltration of the rotator cuff musculature. We devised a system to classify the rotator cuff tendon stump by magnetic resonance imaging (MRI) signal intensity and investigated prognosis-related factors associated with retear based on other MRI findings. METHODS We analyzed and compared the signal intensity of the rotator cuff tendon stump and deltoid on preoperative T2-weighted fat-suppressed MRI in 305 patients who underwent primary arthroscopic rotator cuff repair. We also investigated the tear size, Goutallier stage, and global fatty degeneration index. RESULTS In a type 1 stump, the tendon stump had a lower (darker) signal intensity than the deltoid. In type 2, the signal intensities of the tendon stump and deltoid were equivalent. In type 3, the signal intensity of the tendon stump was higher (whiter) than that of the deltoid. Multiple regression analysis of the association between retear and other parameters identified stump type (odds ratio [OR], 4.28), global fatty degeneration index (OR, 2.99), and anteroposterior tear size (OR, 1.06) as significant factors. The retear rates were 3.4% for type 1 stumps, 4.9% for type 2, and 17.7% for type 3. CONCLUSIONS Type 3 stumps had a significantly higher retear rate, suggesting that stump signal intensity may be an important indicator for assessing the stump's condition. Our stump classification may be useful in choosing suture techniques and postoperative therapies.

Abstract
Background: Arthroscopic rotator cuff repair is a common but technically difficult
surgical technique. This study describes a novel arthroscopic rotator cuff
repair technique where the repair was performed while visualized entirely
from the glenohumeral joint. A single-row knotless tension band inverted
mattress suture technique was utilized with fixation obtained via suture
anchors. The technique was relatively easy to perform and demonstrated good
repair strength and footprint compression in an ex vivo ovine model. Purpose: To evaluate the safety and efficacy of this technique in 1000 consecutive
patients. Study Design: Case series; Level of evidence, 4. Methods: This study was a retrospective analysis of prospectively collected data in
1000 consecutive patients. Included patients underwent primary arthroscopic
rotator cuff repair by a single surgeon performing the undersurface repair
technique and attended 6-month follow-up with ultrasound evaluation to
determine repair integrity. Exclusion criteria were irreparable tears,
incomplete repairs, tendon reconstruction with a synthetic patch, and
revision cases. Results: The only complication was retear. The overall retear rate at 6 months
following repair with the undersurface technique was 8.5%. The mean ± SEM
operative time for the technique was 16 ± 0.3 minutes (range, 4-75 minutes).
There were no infections. Smaller tears were repaired faster and had better
healing rates. Conclusion: The novel all-inside arthroscopic rotator cuff repair technique was safe and
significantly faster and provided better healing rates than other repair
techniques. The retear rate of 8.5% is, to the authors’ knowledge, the
lowest reported rotator cuff retear rate in a large cohort of patients based
on a single technique.

Abstract
OBJECTIVES The reliability of ultrasonic strain elastography (SEL) used to detect abnormalities in the supraspinatus tendon is unclear. Thus, the aim of this study was to investigate the reliability of SEL in the supraspinatus tendon. DESIGN An intra-rater and inter-rater reliability study. SETTING A single-centre study conducted at the University of Southern Denmark. PARTICIPANTS Twenty participants with shoulder pain and MRI-verified supraspinatus tendinosis and 20 asymptomatic participants (no MRI). PRIMARY AND SECONDARY OUTCOME MEASURES Raw values (RAW) and ratios (deltoid muscle (DELT) and gel pad (GEL) as reference tissues) were calculated and mean values of measurements from three regions of the supraspinatus tendon were reported. Colour scale ratings and number of yellow/red lesions from the three areas were also included. RESULTS Intra-rater reliability showed intraclass correlation coefficients (ICCs) for RAW, DELT and GEL: 0.97 (minimal detectable change (MDC): 0.28 (6.36% of the mean)), 0.89 (MDC: 2.91 (20.37%)) and 0.73 (MDC: 1.61 (58.82%)), respectively. The ICCs for inter-rater reliability were 0.89 (MDC: 0.47 (10.53%)), 0.78 (MDC: 3.69 (25.51%)) and 0.70 (MDC: 1.75 (62.63%)), respectively.For colour scale ratings, intra-rater reliability (linear weighted kappa) ranged from 0.76 to 0.79, with the inter-rater reliability from 0.71 to 0.81. For the number of lesions, intra-rater reliability ranged from 0.40 to 0.82 and inter-rater reliability from 0.24 to 0.67. CONCLUSIONS Intra-rater and inter-rater reliability were excellent for raw values and for ratios with deltoid muscle as the reference tissue, and good for ratios with gel pad as the reference tissue. The reliability of colour scale ratings was substantial-to-almost perfect, and for the number of lesions fair-to-almost perfect.Although high reliability was found, validity and responsiveness of these elastographic methods needs further investigation. ETHICS APPROVAL The study protocol was approved by the Ethics Committee for the Region of South Denmark (S-20160115) and reported to the Danish Data Protection Agency (2014-41-3266).

Abstract
Background Investigation of the use of preoperative MRI for providing prognostic information regarding clinical outcome following rotator cuff repair has been limited. Purpose To determine whether patients with more severe rotator cuff tears of the shoulder at preoperative MRI have a greater degree of residual pain and disability after rotator cuff repair. Materials and Methods This retrospective study included a cohort of 141 patients who underwent surgical repair of a full-thickness rotator cuff tear at a single institution between April 16, 2012, and September 3, 2015. The mean patient age was 56.8 years, and there were 100 men (mean age, 56.1 years) and 41 women (mean age, 56.3 years). Patients completed the Disabilities of the Arm, Shoulder, and Hand (DASH) survey (lower score indicates less pain and disability) before and 1 year after surgery. One musculoskeletal radiologist blinded to the DASH scores measured the maximal anterior-posterior width and medial-lateral retraction of the rotator cuff tear on the preoperative MRI and assessed tendon degeneration and composite muscle atrophy and fatty infiltration using categorical grading scales (grade 0 indicates no tendon degeneration or muscle atrophy and fatty infiltration, and higher grades indicate incrementally more severe tendon degeneration or muscle atrophy and fatty infiltration). Generalized estimating equation models were used to determine the association between preoperative MRI findings and the postoperative DASH score. Results There was a significant positive association (P < .05) between the measured tear width (estimate, 2.05), measured tear retraction (estimate, 3.52), and tendon degeneration grade (estimate, 1.59) and the postoperative DASH score. There was no significant association (P = .49) between the composite muscle atrophy and fatty infiltration grade (estimate, 0.31) and the postoperative DASH score. Conclusion Patients with larger rotator cuff tears, more tendon retraction, and more severe tendon degeneration have worse clinical outcome scores 1 year after rotator cuff repair. © RSNA, 2019.

Abstract
Background The purpose of this study is to determine the pre-operative factors that are associated with reparability of the large-sized and massive rotator cuff tears. Methods Sixty-six patients were included in this prognostic study. Demographic data, radiographic and MRI parameters were collected. Arthroscopic rotator cuff repair was performed for all included patient. Complete rotator cuff repair was achieved when the tendon covered up at least 50% of the anatomical footprint. The receiver operating characteristic (ROC) curve was analysed to define the cut-off level of each significant factor. Results Eleven large-sized rotator cuff tears and fifty-five massive rotator cuff tears were defined from MRI. Fifty-four patients were in the complete repair group, and twelve patients were in the partial repair group. The mean duration between MRI and surgery of 5.5 weeks. Reparability was correlated with age, mediolateral (ML) and anteroposterior (AP) tear size, rotator cuff arthropathy, superior migration of humeral head, fatty infiltration and atrophy of the supraspinatus muscle, and fatty infiltration of infraspinatus muscle (p < 0.05). The ROC curve defined a cut-off level of each predicting factor which included age of ≥65 years, mediolateral tear size of ≥36 mm, anteroposterior tear size of ≥22 mm, Hamada’s rotator cuff arthropathy of ≥class2, acromiohumeral interval of ≥6 mm, ≥stage3 supraspinatus fatty infiltration, the presence of supraspinatus muscle atrophy, and ≥ stage1 infraspinatus fatty infiltration. In multivariated regression analysis, age, acromiohumeral interval, and anteroposterior tear size were statistically associated with the reparability. The intra- and inter-observer reliabilities were moderate to excellent. Conclusion Age, ML tear size, AP tear size, rotator cuff arthropathy, superior migration of humeral head, fatty infiltration of supraspinatus and infraspinatus muscles and supraspinatus muscle atrophy all correlate with reparability of large to massive rotator cuff tear.

Abstract
PURPOSE To analyze clinical outcomes, return to sports, and complications in a series of patients with painful partial-thickness rotator cuff tears treated with arthroscopic in situ repair with suture anchors who had a minimum of 8 years of follow-up. METHODS Sixty-two patients who had undergone an arthroscopic in situ repair for partial-thickness rotator cuff tears were evaluated. All injuries involved the supraspinatus tendon. Clinical assessment consisted of glenohumeral range-of-motion measurement and the American Shoulder and Elbow Surgeons score. Pain was rated by using a visual analog scale. We assessed return to sports and the level of performance achieved after surgery. Postoperative complications were also assessed. RESULTS Mean age was 52.4 years (range, 32 to 67 years), and mean duration of follow-up was 10.4 years (range, 8 to 12 years). All active range-of-motion parameters improved significantly (P < .0001). The American Shoulder and Elbow Surgeons score improved from 45.6 to 85.1; and the visual analog scale scores improved from 6.4 to 1.6 (P < .0001). Thirty patients participated in sports before injury: 21 were recreational athletes and 9 were competitive athletes. Twenty-six (87%) were able to return to sports, and 24 (80%) returned to the same level they had achieved before injury. No significant difference regarding functional outcomes or return to sports was found between patients with articular-sided tears and those with bursal-sided tears. No revision surgeries were performed. Three patients had postoperative adhesive capsulitis that responded favorably to physical therapy. CONCLUSIONS During long-term follow-up, arthroscopic in situ repair of partial-thickness rotator cuff tears produces excellent functional outcomes in more than 80% of patients, and revision rates are low. Most patients return to their chosen sport at the same level they had achieved before injury. The results are equally favorable for articular-sided and bursal-sided tears.

Abstract
Objective The aim of this study was to evaluate factors associated with the needle breakage of antegrade suture passer and the effect of intratendinous remnant needle tip on clinical outcomes after rotator cuff repair. Methods We retrospectively reviewed 283 patients (138 men and 145 women; mean age: 59.7 ± 9.3 years) who underwent arthroscopic repair for full-thickness rotator cuff tear. We evaluated the characteristics of 16 patients in whose needle tip had been broken and embedded and remained in the rotator cuff (remnant needle group) and compared them with the remaining 267 patients (control group). Afterwards, another 64 patients were selected from control group (1:4 matching) after propensity score matching (PSM). The groups were compared anatomically with MRI or ultrasonography and functionally (serial pain VAS and ROM; ASES, Constant, UCLA and SST scores) at a minimum follow-up of 1 year. Results The remnant needle group showed preoperative thicker tendon (6.72 mm vs 5.33 mm, p = 0.047), higher tendinosis (mean grade, 1.88 vs. 1.43, p = 0.029), and more frequent delaminated tears (p = 0.035) compared with control group. When we compare the clinical outcomes after PSM, the initial pain VAS of the remnant needle tip group was higher up to 3 months (pain VAS: 4.13 ± 2.07 vs 2.48 ± 1.61 (p = 0.032) at 5 weeks and 3.79 ± 2.12 vs 2.25 ± 1.76 (p = 0.044) at 3 months), however the difference disappeared after 6 months postoperatively. In final evaluation, there was no significant differences in every outcome parameters (all p > 0.05). Conclusion Breakage of the needle of the antegrade suture passer occurred more frequently in the thicker tendon, higher tendinosis, and delaminated tears. The retained broken needle tip was associated with higher pain scores during the early postoperative period, but revealed no difference in final outcomes by using PSM.

Abstract
INTRODUCTION Partial-thickness rotator cuff tears are a common cause of shoulder pain and disability. Arthroscopic repair is an effective treatment for partial articular supraspinatus tendon avulsion (PASTA) lesions, and transtendon repair and completion of the tear and repair are the surgical techniques commonly used to treat such lesions. Our aim was to retrospectively evaluate the minimum 24-month clinical and radiological results of PASTA. MATERIALS AND METHODS Patients suffering from PASTA lesion who underwent arthroscopic repair with a minimum 24-month follow-up were included in this study. The Constant and Murley score (CMS) was used to assess the patients' functionality pre- and postoperatively. The postoperative patient assessment included the simple shoulder test (SST). Postoperative tendon integrity was evaluated by ultrasound examination. RESULTS 151 patients (153 shoulders) were retrospectively evaluated 73.9 (24-142) months after a completion-repair (94 cases) or transtendon repair (59 cases) of a PASTA lesion. The CMS significantly improved from 47.7 (22-63) preoperatively to 84.2 (62-100) postoperatively (p < 0.001). The mean postoperative SST score was 10.1 (5-12), and 95% of patients were satisfied with the surgery. No significant differences were noted between the two techniques in terms of postoperative CMS, SST score and satisfaction. Seventy-four and 43 cases treated with completion and repair and transtendon repair, respectively, performed ultrasound examination 66.1 (24-142) months after surgery. The overall retear rate was 13.7%, supraspinatus retears were observed in ten shoulder subjected to completion and repair (13.5%) and six shoulders subjected to transtendon repair (13.9%), and no significant differences were noted between the two techniques as for CMS (p = 0.896), SST (p = 0.973), satisfaction (p = 0.621) and retear (p = 0.999). Males and younger patients had a higher postoperative CMS (p values < 0.001), and SST score (p < 0.001 and p = 0.038, respectively). CONCLUSIONS Arthroscopic repair of PASTA lesion achieves high rates of repair integrity regardless of repair type and high levels of functional recovery and patient satisfaction 6 years after surgery.

Abstract
BACKGROUND Limited information is available regarding the characteristics of delaminated rotator cuff tears as compared with nondelaminated tears. Furthermore, there is conflicting information regarding the effects of delamination on the anatomic healing of repaired cuffs. PURPOSE To evaluate the characteristics and anatomic outcomes of delaminated rotator cuff tears in comparison with nondelaminated tears to determine whether delamination is a negative prognostic factor affecting rotator cuff repair outcomes. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Between 2010 and 2014, 1043 patients were enrolled in the study to assess the prevalence of delamination. Among them, the findings from 531 patients who underwent magnetic resonance imaging or computed tomographic arthrography at least 1 year after surgery were included to determine whether delamination was a negative prognostic factor affecting the anatomic outcomes of arthroscopic rotator cuff repair. Delamination was assessed intraoperatively and defined by distinguishable edge cleavage tearing or interstitial horizontal gap between the articular and bursal surfaces of the torn tendon. One of 3 repair techniques (modified Mason Allen, single row, or double row) was used according to tear configuration and tendon mobilization. The authors evaluated visual analog scale scores for pain and satisfaction and American Shoulder and Elbow Surgeons scores to quantify clinical outcomes. RESULTS The incidence of delamination was 42.9% (447 of 1043). As compared with those with nondelaminated tears, patients with delaminated tears were older ( P < .001) and had longer symptom duration ( P = .019), larger tear sizes and retractions ( P < .001 for both), higher grades of fatty infiltration of the rotator cuff muscles (all P < .001), and poorer tendon quality ( P < .001). The overall healing failure rate was 19.0% (101 of 531). In univariate analysis, the rate of healing failure for the repaired cuffs was significantly higher in the delaminated group (delaminated tears, 60 of 238, 25.2%; nondelaminated tears, 41 of 293, 14.0%; P = .001). However, results of subgroup and multivariate analyses showed that the presence of delamination was ultimately not an independent risk factor for the failure of cuff healing. Between the delaminated and nondelaminated groups, there was no significant difference in postoperative functional outcomes. CONCLUSION The results suggest that delaminated rotator cuff tears might represent chronic degenerative tears of longer symptom duration, with larger tear sizes and higher grades of fatty infiltration in older patients. It appears that delamination could be a confounding factor, not an independent prognostic factor, affecting rotator cuff healing.

Abstract
BACKGROUND Scoring systems integrating possible prognostic factors and predicting rotator cuff healing after surgical repair could provide valuable information for clinical practice. PURPOSE To determine the prognostic factors predictive of rotator cuff healing after surgical repair and to integrate these factors into a scoring system. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS The authors reviewed the records of 603 patients who, at least 12 months after primary rotator cuff repair by a single surgeon, had magnetic resonance imaging or computed tomographic arthrography to assess repair integrity. The mean age at the time of surgery was 60 years (range, 39-81 years), and 378 patients were women (62.7%). Previous known or suggested factors affecting cuff integrity were analyzed through univariate and multivariate analyses. Factors identified in the multivariate analysis were integrated in a scoring system based on odds ratios (ORs). RESULTS The overall healing failure rate was 24%. The following independent risk factors were identified in the multivariate analysis: age >70 years at the time of surgery ( P = .003, OR = 2.71), size of the tear in anteroposterior dimension ( P = .033, OR = 1.94) and retraction ( P = .000, OR = 4.56), fatty infiltration of infraspinatus exceeding grade 2 ( P = .001, OR = 2.91), low bone mineral density (T score ≤ -2.5, P = .04, OR = 1.95), and high level of work activity ( P = .036, OR = 2.18). A 15-point scoring system comprised the following: 4 points for retraction; 3 points for fatty infiltration of infraspinatus; and 2 points for anteroposterior tear size, age, bone mineral density, and work activity, weighted according to multivariate analysis ORs. Patients with ≤4 points had a 6.0% healing failure rate, and those with ≥5 and ≥10 points had 55.2% and 86.2% healing failure rates, respectively. CONCLUSION A numerical scoring system including significant clinical and radiological factors was designed to predict healing of the rotator cuff after surgical repair. This scoring system helped predict the adequacy of the repair and assist in deciding the appropriate treatment options.

Abstract
BACKGROUND Movement toward a value-based health-care system necessitates the development of performance measures to compare physicians, hospitals, and health-care systems. Patient-reported outcomes (PROs) are a potential metric. However, valid use of PROs hinges on the ability to risk-adjust for baseline patient differences across a surgeon's panel of patients. The purpose of this study was to propose an approach for baseline risk adjustment and evaluate the importance of risk adjustment when comparing surgeons' performance of rotator cuff repair. METHODS Patients (n = 995) treated with arthroscopic rotator cuff repair by 34 surgeons from 2010 to 2017 were identified from a large sports medicine clinical data registry. A linear regression model was used to adjust for baseline PROs, patient demographics, and clinical characteristics to predict American Shoulder and Elbow Surgeons (ASES) change scores for each surgeon. A risk-adjusted performance measure was calculated as the difference between the average unadjusted ASES change scores and the risk-adjusted predicted ASES change scores across all patients treated by a surgeon. RESULTS The differences between unadjusted and risk-adjusted performance scores varied widely across surgeons (range, -13.8 to 10.3 ASES points). Use of the risk-adjusted performance scores resulted in a dramatic change in the relative ranking of surgeons, compared with the ranking based on the observed ASES change scores, with 31 of the 34 surgeons' rank changing following risk adjustment. On average, the observed ASES scores improved from 49.5 ± 17.5 at baseline to 78.0 ± 22.5 at 6 months across all surgeons. In the risk-adjustment model (R = 0.44), male sex, Workers' Compensation status, higher scores on the Veterans RAND 12-item Health Survey (VR-12), lower baseline ASES scores, fair and poor tendon quality, and night pain all had a significant effect on the predicted ASES change scores (p < 0.05). CONCLUSIONS Our results show wide variation of nearly 25 points in the risk-adjusted 6-month ASES performance difference from the highest to the lowest-performing surgeons. Additionally, 91% of surgeons' rank changed following risk adjustment. This suggests that performance measurement that does not account for baseline patient characteristics would likely result in incorrect conclusions about a surgeon's relative performance based on PROs.

Abstract
BACKGROUND No study to date has directly evaluated rotator cuff repair results among smokers. PURPOSE To evaluate whether smoking affects healing after arthroscopic rotator cuff repair through propensity score matching (PSM). STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Among 249 patients who underwent arthroscopic repair of full-thickness rotator cuff tears, 34 current heavy smokers were selected with a smoking history >20 pack-years (mean ± SD pack-years, 33.91 ± 12.13). Characteristics between current heavy smokers and nonsmokers were compared. According to the PSM technique, 34 nonsmokers were selected after 1:1 matching for age, fatty infiltration, and tear size-the main prognostic factors of outcomes after rotator cuff repair. Each patient's outcome evaluation was completed anatomically at a minimum of 6 months (magnetic resonance imaging or ultrasonography) and functionally at a minimum of 1 year (pain visual analog scale, range of motion, American Shoulder and Elbow Surgeons, Constant, University of California, Los Angeles, and Simple Shoulder Test scores), and every outcome was analyzed in the matched smoker and nonsmoker groups. RESULTS Current heavy smokers had a higher incidence of male sex ( P < .001), heavy manual work ( P = .025), high bone density ( P = .036), and poor tendinosis grade ( P = .028). After adjustment for the confounding variables by PSM, the matched smoker group showed a significantly higher healing failure rate than the matched nonsmoker group (29.4% vs 5.9%, P = .023). However, we failed to detect significant differences in the functional outcomes between the matched groups ( P > .05). CONCLUSION Smoking affected healing failure after arthroscopic rotator cuff repair. Attention should be paid to smokers, especially current heavy smokers, in cases of rotator cuff repair surgery.

Abstract
Different regenerative medicine approaches for tendon healing exist. Recently, especially gene therapy gained popularity. However, potential mutagenic and immunologic effects might prevent its translation to clinical research. Chemically modified mRNA (cmRNA) might bypass these limitations of gene therapy. Therefore, the purpose of this study was to evaluate the early healing properties of Achilles tendon defects in rats treated with basic fibroblast growth factor (bFGF) cmRNA. Forty male Lewis rats were used for the study and randomly assigned to two study groups: (1) treatment with cmRNA coding for bFGF and (2) noncoding cmRNA control. Protein expression was measured using in vivo bioluminescence imaging at 24, 48, and 72 h, as well as 14 days. Animals were euthanized 2 weeks following surgery. Biomechanical, histological, and immunohistological analyses were performed with the significance level set at p < 0.05. Protein expression was evident for 3 days. At 14 days, bioluminescence imaging revealed only little protein expression. Biomechanically, tendons treated with bFGF cmRNA showed a construct stiffness closer to the healthy contralateral side when compared with the control group (p = 0.034), without any significant differences in terms of load to failure. Hematoxylin and eosin staining detected no side effects of the treatment, as signs of inflammation, or necrosis. Furthermore, it revealed the shape of the nuclei to be more oval in the bFGF group in the tendon midsubstance (p = 0.043) with a reduced cell count (p = 0.035). Immunohistological staining for type I, II, III, and IV collagen did not differ significantly between the two groups. In conclusion, this pilot study demonstrates the feasibility of a novel messenger RNA (mRNA)-based therapy for Achilles tendon defects using chemically modified mRNA coding for bFGF.

Abstract
BACKGROUND Treatment of partial-thickness cuff tears remains controversial. Although conservative therapy may treat symptoms, these defects do not spontaneously heal and conversion to a full-thickness lesion with subsequent repair may alter the tendon footprint. The ability to induce new tissue formation and limit tear progression in intermediate- and high-grade partial-thickness tears without surgical repair may represent a significant advancement in the treatment paradigm for these lesions. METHODS We prospectively enrolled 33 patients with chronic, degenerative, intermediate-grade (n = 12) or high-grade (n = 21) partial-thickness tears (11 articular, 10 bursal, 4 intrasubstance, and 8 hybrid) of the supraspinatus tendon in a multicenter study. Following arthroscopic subacromial decompression without repair, a bioinductive implant was attached over the bursal surface of the tendon. Clinical outcomes were assessed using American Shoulder and Elbow Surgeons and Constant-Murley scores preoperatively and at 3 and 12 months postoperatively. Magnetic resonance imaging was performed to assess postoperative tendon healing and thickness at the original tear site. RESULTS At 1-year follow-up, clinical scores improved significantly (P <.0001) and the mean tendon thickness increased by 2.0 mm (P <.0001). Magnetic resonance imaging evidence of complete healing was found in 8 patients and a considerable reduction in defect size was shown in 23, whereas 1 lesion remained stable. In 1 noncompliant patient with a high-grade articular lesion, progression to a full-thickness tear occurred while shoveling snow 1 month after surgery. No serious adverse events related to the implant were reported. CONCLUSIONS Arthroscopic implantation of a bioinductive collagen scaffold is a safe and effective treatment for intermediate- to high-grade partial-thickness rotator cuff tears of the supraspinatus tendon.

Abstract
PURPOSE The optimum treatment strategy for the surgical management of partial-thickness rotator cuff tears (PTRCT) is evolving. In this study, two research questions were sought to be answered: "Does the repair technique for PTRCTs involving >50% of the tendon thickness have an effect on structural and functional outcomes of arthroscopic repair?" and "Is there a difference in outcomes of arthroscopically treated articular- and bursal-sided PTRCTs?". METHODS A systematic review according to the PRISMA statement was conducted to identify all literature published reporting on outcomes of arthroscopic treatment of PTRCTs classified with the Ellman classification with minimum 2-year follow-up. Prospective randomized trials were eligible for quantitative synthesis. A total of 19 studies, published between 1999 and 2015, met the inclusion criteria of this systematic review. Two studies reporting outcomes of articular-sided PTRCTs with prospective randomized study design were included in quantitative synthesis calculations. RESULTS Arthroscopic repair of PTRCTs >50% thickness results in significant pain relief and good to excellent functional outcomes. When in situ repair was compared with repair of the tendon after completion to full-thickness RCT, there were no significant differences in functional or structural outcomes or complication rates. The best treatment method for low-grade PTRCTs remains unclear. CONCLUSIONS The repair technique (in situ repair versus repair of the tendon after completion to full-thickness RCT) did not significantly affect the outcomes for arthroscopic repair of PTRCTs >50% thickness. The current literature contains evidence for inferior outcomes and higher failure rates after arthroscopic debridement of bursal-sided compared to articular-sided PTRCTs, and some evidence suggests that repair of lower-grade bursal-sided tears may be beneficial over debridement.

Abstract
BACKGROUND High-grade partial-thickness rotator cuff tears (hPTRCTs) are frequently encountered in the shoulder. However, little information is available on the prevalence or timing of tear progression. Purpose/Hypothesis: The purpose was to prospectively evaluate the structural progression of hPTRCTs with a minimum follow-up of 1 year using magnetic resonance imaging (MRI). The hypothesis was that a substantial portion of hPTRCT patients would experience tear progression or evolution to a full-thickness rotator cuff tear. STUDY DESIGN Case series; Level of evidence, 4. METHODS Between May 2010 and December 2015, 362 patients were diagnosed with hPTRCT (tear involvement >50% of the mediolateral length of the footprint) of the supraspinatus and were treated nonoperatively. Among these patients, 81 underwent follow-up MRI at least 1 year after initial presentation, and these patients were included in the final analysis. Initial and follow-up MRIs were used to determine whether tears had improved, had not changed, or had progressed. A change in tear involvement of >20% was defined as a significant change. Patients were categorized as follows: (1) a decrease in tear involvement of >20% (improved), (2) an increase or decrease of ≤20% (no change), or (3) an increase in tear involvement of >20% (progressed). Demographic data and morphologic data were analyzed to identify variables related to tear progression. Among them, severity of tendinosis was graded using MRIs: grade 1 (mild tendinosis), mild focal increase in tendon signal; grade 2 (moderate tendinosis), moderate focal increase in tendon signal; and grade 3 (marked tendinosis), marked generalized increase in tendon signal. RESULTS At initial diagnosis, 23 were articular-side (28%) and 58 were bursal-side (72%) hPTRCTs. The study cohort was composed of 51 women and 30 men, and the mean patient age was 62.3 years (range, 41-77 years). Follow-up MRI was performed at a mean 19.9 ± 10.9 months (range, 12-52 months). A significant change in tear involvement was observed at follow-up. In 13 patients (16%, 2 articular-side and 11 bursal-side tears), tears were classified as progressed (the progressed group); in 48 patients (59%), tears exhibited no change (the unchanged group); and in 20 patients (25%, 9 articular-side and 11 bursal-side tears), tears were improved (the improved group). Univariate analysis showed initial tendinosis grade was significantly different in the 3 groups (grade 1, 2, and 3: 5, 4, and 4 in progressed; 36, 11, and 1 in unchanged; 10, 8, and 2 in improved group, respectively, P = .007). CONCLUSION Although progression of hPTRCT in the long term is uncertain, after 1-year follow-up with MRI, tears progressed in 16% of the tears in this study. Furthermore, some tears were healed or reduced in size, which indicates that decisions to undertake surgical repair at time of presentation may be excessive.

Abstract
PURPOSE To investigate clinical outcomes in patients who underwent arthroscopic repair of isolated partial-thickness rotator cuff tears (PTRCTs) of the supraspinatus tendon with a minimum follow-up period of 5 years. METHODS All patients who had undergone arthroscopic repair of isolated PTRCTs at least 5 years earlier were included. Preoperatively and postoperatively, the American Shoulder and Elbow Surgeons, QuickDASH (short version of Disabilities of the Arm, Shoulder and Hand questionnaire), and Short Form 12 Physical Component Summary scores were collected, along with postoperative satisfaction (10-point scale) and return to activity. The associations between (1) patient age and outcome scores and (2) location of partial-thickness tear (articular vs bursal sided) and outcome scores were evaluated. Failure was defined as revision surgery of the rotator cuff repair. RESULTS The study included 24 shoulders (24 patients comprising 9 women and 15 men). Follow-up data were available on 20 shoulders (7 women and 13 men, 83% follow-up) at a mean of 6 ± 1 years postoperatively. The mean age at index surgery was 55 ± 11 years; 6 bursal- and 14 articular-sided tears were repaired. No patient required revision surgery. All scores significantly improved from preoperatively to postoperatively (P < .05); the median satisfaction rating (1, not satisfied; 10, completely satisfied) was 10 (range, 1-10). Neither patient age nor tear location correlated with outcome scores (P > .05). Seventeen patients indicated that they participated in previous recreational activity. Of these patients, 13 (76%) returned to the original level or a similar level of activity, 3 (18%) returned to activity at a lower level, and only 1 (6%) indicated an inability to return to activity. CONCLUSIONS Patients undergoing arthroscopic repair of PTRCTs can expect excellent clinical outcomes with low failure rates at midterm follow-up given that no patient progressed to revision rotator cuff repair during follow-up. The return-to-activity rate was very high after repair of isolated PTRCTs. Neither patient age nor tear location was associated with outcome scores. LEVEL OF EVIDENCE Level IV, retrospective case series.
