Abstract
BACKGROUND Arthroscopic rotator cuff repair (ARCR) is one of the most commonly performed orthopaedic procedures; however, it is unclear how to manage patients with symptomatic retears. PURPOSE To perform a systematic review to evaluate the outcomes of revision ARCR in the literature. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS A systematic literature search based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was performed utilizing the Embase, MEDLINE, and Cochrane Library databases. Eligible for inclusion were clinical studies reporting on revision rotator cuff repair. Clinical outcomes were recorded. RESULTS The 17 included studies were composed of 888 shoulders in 885 patients. The mean age of the 885 patients was 58.6 ± 9.1 years, with a mean follow-up of 28.1 ± 22.1 months. The mean visual analog scale score was 2.1 ± 1.8, the mean American Shoulder and Elbow Surgeons score was 75.0 ± 18.3, and the mean Constant score was 67.4 ± 16.6. The overall rate of retears after revision was 25.3%, with an 8.0% reoperation rate including 2.7% undergoing reverse shoulder arthroplasty and 2.0% undergoing subsequent rotator cuff repair. Finally, the complication rate was 8.6%. CONCLUSION Revision ARCR improved patient-reported outcomes, with 92% of patients free from reoperations at a mean follow-up of 2 years. Overall, 78.4% of patients were satisfied at final follow-up; however, the rate of retears was found to be higher than after primary ARCR.

Abstract
BACKGROUND Infusion catheters facilitate a controlled infusion of local anesthetic (LA) for pain control after surgery. However, their potential effects on healing fibroblasts are unspecified. METHODS Rat synovial fibroblasts were cultured in 12-well plates. Dilutions were prepared in a solution containing reduced-serum media and 0.9% sodium chloride in 1:1 concentration. Each well was treated with 500 μl of the appropriate LA dilution or normal saline for 15- or 30-min. LA dilutions included: 0.5% ropivacaine HCl, 0.2% ropivacaine HCl, 1% lidocaine HCl and epinephrine 1:100,000, 1% lidocaine HCl, 0.5% bupivacaine HCl and epinephrine 1:200,000, and 0.5% bupivacaine HCl. This was replicated three times. Dilution of each LA whereby 50% of the cells were unviable (Lethal dose 50 [LD50]) was analyzed. RESULTS LD50 was reached for lidocaine and bupivacaine, but not ropivacaine. Lidocaine 1% with epinephrine is toxic at 30-min at 1/4 and 1/2 sample dilutions. Bupivacaine 0.5% was found to be toxic at 30-min at 1/2 sample dilution. Bupivacaine 0.5% with epinephrine was found to be toxic at 15- and 30-min at 1/4 sample dilution. Lidocaine 1% was found to be toxic at 15- and 30-min at 1/2 sample dilution. Ropivacaine 0.2% and 0.5% remained below LD50 at all time-points and concentrations, with 0.2% demonstrating the least cell death. CONCLUSIONS Though pain pumps are generally efficacious, LAs may inhibit fibroblasts, including perineural fibroblast and endoneurial fibroblast-like cells, which may contribute to persistent nerve deficits, delayed neurogenic pain, and negatively impact healing. Should a continuous infusion be used, our data supports ropivacaine 0.2%. LEVEL OF EVIDENCE Basic Science Study; Animal model.

BMC Musculoskelet Disord 2024; 25:302. [PMID: 38632573 PMCID: PMC11022446 DOI: 10.1186/s12891-024-07431-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2023] [Accepted: 04/09/2024] [Indexed: 04/19/2024] Open
Abstract
BACKGROUND In transtendinous full thickness rotator cuff tears (FTRCT) with remnant cuff, conventionally, cuff remnant of the greater tuberosity (GT) is debrided for better tendon to bone healing. However, larger cuff defect caused overtension on the repaired tendon. The purpose of this study was to compare the clinical outcomes and tendon integrity between remnant preserving and remnant debriding cuff repairs in the transtendinous FTRCT with remnant cuff. METHODS From March, 2012 to October, 2017, a total of 127 patients who had the transtendinous FTRCT with remnant cuff were enrolled in this study. Rotator cuff tears were repaired arthroscopically, with patients divided into two groups: group I (n = 63), where rotator cuff remnants were preserved during the repair, and group II (n = 64), where the remnants were debrided during the repair. Clinical outcomes were assessed at the last follow-up (minimum 2 years) using the UCLA score, ASES score, SST score, Constant Shoulder score, and range of motion (ROM). The analysis of structural integrity and tendon quality was performed using the Sugaya classification on postoperative MRI scans at 8 months after surgery. RESULTS At the final follow-up, UCLA, ASES, SST, and CS scores significantly improved from preoperative values to postoperative (all p < 0.05): UCLA (I: 19.6 ± 6.0 to 31.7 ± 3.2, II: 18.0 ± 5.7 to 31.5 ± 3.2), ASES (I: 54.3 ± 10.7 to 86.5 ± 12.5, II: 18.0 ± 5.7 to 85.8 ± 12.4), SST (I: 5.6 ± 2.8 to 10.2 ± 2.0, II: 5.0 ± 2.9 to 10.1 ± 2.5), CS (I: 74.0 ± 17.2 to 87.8 ± 9.7, II: 62.0 ± 19.2 to 88.3 ± 6.2). However, there were no significant differences between the two groups (p > 0.05). Also, remnant preserving cuff repair yielded significantly better tendon quality on postoperative MRI (p < 0.05). The incidence of re-tear (Sugaya's Type IV and V) was not significantly different between the two groups (I:17% vs. II:19%; p = 0.053). CONCLUSIONS Remnant preserving rotator cuff repairs, which facilitate tendon-to-tendon healing, are superior in terms of tendon quality and are the preferred option for transtendinous FTRCT.

Abstract
Background The goal of this study was to estimate the short-term (∼2 years) healthcare costs of failed primary arthroscopic rotator cuff repair (RCR) in the United States. Methods A review of current literature was performed to estimate the number of RCR performed in the United States in the year 2022 and the rate of progression of these patients to lose repair continuity, reach clinical failure, and progress to nonoperative intervention and revision procedures. A review of the current literature was performed to estimate the costs incurred by these failures over the ensuing 2-year postoperative time period. Results The direct and indirect healthcare costs of structural and clinical failure of primary RCR performed in 2022 are estimated to reach $438,892,670 in the short-term postoperative period. The majority of the costs come from the estimated $229,390,898 in nonoperative management that these patients undergo after they reach clinical failure. Conclusion The short-term healthcare costs of failed arthroscopic RCR performed in the United States in 2022 are predicted to be $438,892,670. Although RCR improves quality of life, pain, function, and is cost-effective, there remains great potential for reducing the economic burden of failed RCR repairs on the US society. Investments into research aimed to improve RCR healing rates are warranted. Clinical Relevance Although RCR improves quality of life, pain, function, and is cost-effective, this study provides evidence that there remains great potential for reducing the economic burden of failed RCR repairs on the US society. Investments into research aimed to improve RCR healing rates are warranted.

Abstract
BACKGROUND The extent of fatty infiltration and rotator cuff (RC) atrophy is crucial for the clinical results after rotator cuff repair (RCR). The purpose of this study was to evaluate changes in fatty infiltration and RC atrophy after revision RCR and to correlate them with functional outcome parameters. METHODS Patients who underwent arthroscopic revision RCR for symptomatic recurrent full-thickness tear of the supraspinatus tendon between 2008 and 2014 and were retrospectively reviewed with a minimum follow up of 2 years. Magnetic resonance imaging (MRI) was performed pre- and postoperatively to assess 1) tendon integrity after revision RCR according to Sugaya classification, (2) RC atrophy according to Thomazeau classification, and (3) fatty infiltration according to Fuchs MRI classification. Constant score (CS) and the American Shoulder and Elbow Surgeon (ASES) score were used to correlate functional outcome, tendon integrity, and muscle degeneration. RESULTS 19 patients (17 males and 2 females) with a mean age of 57.5 years (range, 34 to 72) were included into the study at a mean follow-up of 50.3 months (range, 24 - 101). At final evaluation, 9 patients (47%) presented with intact RCR and 10 patients (53%) suffered a re-tear after revision repair. No progress of fatty infiltration was observed postoperatively in the group with intact RC, atrophy progressed in only 1 out of 9 patient (11%). Fatty infiltration progressed in 5/10 patients (50%) and RC atrophy increased in 2/10 patients (20%) within the re-tear group. CS (42.7 ± 17.7 preop, 65.2 ± 20.1 postop) and ASES (47.7 ± 17.2 preop, 75.4 ± 23.7 postop) improved significantly from pre- to postoperatively (p < 0.001). A positive correlation between fatty infiltration and RC integrity was detected (r = 0.77, p < 0.01). No correlation between clinical outcome and tendon integrity or RC atrophy was observed. CONCLUSION Arthroscopic revision RCR leads to reliable functional outcomes even in case of a recurrent RC retear. An intact RCR maintains the preoperative state of fatty infiltration and muscle atrophy but does not lead to muscle regeneration. LEVEL OF EVIDENCE Level IV; Therapeutic study.

Abstract
PURPOSE Rotator cuff repair (RCR) is commonly performed and can have good functional outcomes. However, failure of RCR surgery can be challenging for both patient and surgeon alike. This study examines the outcomes of early revision RCR for the management of clinically failed RCRs. METHODS Thirty-six patients undergoing revision RCR within 1 year of primary surgery were evaluated. Range of motion (ROM) and patient-reported outcomes (PROMs) were assessed at baseline, post-primary RCR, and post-revision RCR. RESULTS Patients with a documented repair failure after primary RCR failed to improve in both ROM and PROMs compared to before primary RCR. Following early revision, RCR SANE (p = 0.024, p < 0.001), ASES (p = 0.004, p < 0.001), and SST (p < 0.001, p = 0.001) scores improved significantly compared to pre-primary and pre-revision scores, respectively. Documentation of a new traumatic injury did not affect clinical or functional outcomes compared to atraumatic re-tears. Number of tendons torn was positively correlated with higher SANE scores (r = 0.638, p = 0.008) and negatively correlated with SST score (r = -0.475, p = 0.03) and improvement in forward elevation (r = -0.368, p = 0.03) after primary RCR. There were significant correlations between number of tendons torn and improvement in SANE (r = 0.664, p = 0.007) and ASES scores (r = 0.468, p = 0.043) from post-primary RCR to post-revision RCR. CONCLUSION Early revision after failed RCR can lead to clinically significant improvement in functional outcomes. The presence of a traumatic re-injury does not appear to affect revision RCR outcomes as it does in the primary setting. Patients with early clinical failures of primary RCR may benefit from early revision RCR. LEVEL OF EVIDENCE III: Retrospective Case Series.

Abstract
BACKGROUND Few studies have investigated postoperative tendon integrity after reoperation for failed rotator cuff repair. The purpose of this study was to evaluate the anatomic and clinical outcomes of arthroscopic revision rotator cuff repair (AR-RCR) and identify the risk factors related to re-retear. METHODS Sixty-nine consecutive patients (mean age, 55 years) with primary failed open (38%) or arthroscopic (62%) cuff repairs underwent AR-RCR and were reviewed regarding clinical examination findings and imaging studies. Patients with massive cuff tears and upward humeral migration (acromiohumeral distance < 6 mm) or glenohumeral osteoarthritis were excluded. Revision repair was performed by a single, experienced shoulder surgeon. Complete footprint coverage was achieved in all cases using a single-row (70%), double-row (19%), or side-to-side (11%) technique. The primary outcome measure was tendon healing assessed with magnetic resonance imaging (57 cases) or computed tomography arthrogram (12 cases) performed at minimum 1-year follow-up. Secondary outcome measures included functional outcome scores, subjective results, and complications. The mean follow-up period was 43 months (range, 12-136 months). RESULTS The cuff tendons did not heal to the tuberosity in 36% of the shoulders (25 of 69) following revision cuff surgery. Absence of tendon healing was associated with poorer shoulder function (average Constant score, 69 ± 20 vs. 54 ± 18; P = .003) and a decreased Subjective Shoulder Value (72% vs. 54%, P = .002). Factors that were negatively associated with tendon healing were age ≥ 55 years (odds ratio [OR], 4.5 [95% confidence interval, 1.6-12.5]; P = .02), tendon retraction of stage 2 or higher (OR, 4.4 [95% confidence interval, 1.4-14.3]; P = .01), and fatty infiltration index > 2 (OR, 10.2; P < .0001). No differences in retear rates were found between single-row and double-row cases. In 36 shoulders, tissue samples were harvested and submitted for bacteriologic culture analysis; 13 (36%) showed positive findings for infection (Cutibacterium acnes in 12 of 13) and associated antibiotic treatment was given. Overall, 25% of patients had unsatisfactory clinical results and 22% were disappointed or dissatisfied. At last follow-up, 4 patients (5.7%) underwent reoperations, with a second AR-RCR in 1 and conversion to reverse shoulder arthroplasty in 3. CONCLUSION Despite careful patient selection and intraoperative complete footprint coverage, in this study the tendons did not heal to bone in 36% of cases after revision cuff surgery. The absence of tendon healing is associated with poorer clinical and subjective results. Patients aged ≥ 55 years and patients with larger tears (stage 2 or higher) and/or muscle fatty infiltration (fatty infiltration index > 2) have significantly lower rates of healing. Surgeons should be aware that structurally failed cuff repair may also be associated with low-grade infection.

Abstract
Failed rotator cuff repairs present a complex issue for treating surgeons. Many methods of management exist for this pathology including revision repair with biologic augmentation, repairs with allograft, tendon transfers, superior capsular reconstruction, balloon arthroplasty, bursal acromial reconstruction, and reverse total shoulder arthroplasty. This review discusses the current literature associated with these management options.

Abstract
Background Healing of the tendon itself is not always related to successful clinical outcomes after rotator cuff repair. It was hypothesized that certain radiologic factors affecting clinical outcomes could exist in case of the retear after arthroscopic rotator cuff repair (ARCR) and the radiologic factors could help predict clinical process. The purpose of this study was to identify the radiologic factors associated with clinical outcomes of the retear after ARCR. Methods Between January 2012 and December 2019, among patients with sufficient footprint coverage for ARCR, 96 patients with Sugaya classification 4 or higher retear on follow-up magnetic resonance imaging were included. The association between clinical outcomes such as American Shoulder and Elbow Surgeons (ASES) score, Constant score and range of motion and radiologic variables such as initial tear dimension, retear dimension, variance of tear dimension, critical shoulder angle, acromial index, and acromiohumeral distance was analyzed. Results Preoperatively, the ASES and Constant scores were 59.81±17.02 and 64.30±15.27, respectively. And at the last follow-up, they improved to 81.56±16.29 and 78.62±14.16, respectively (p<0.01 and p<0.01). In multiple linear regression analysis, the variance of the mediolateral dimension of tear had statistically significant association with the ASES and Constant scores (p<0.01 and p=0.01). Conclusions In patients with the retear after ARCR, the variance in the mediolateral dimension of tear had significantly negative association with the clinical outcomes. This could be considered to be reference as relative criteria and needed more sample and mechanical study.

Abstract
BACKGROUND Retears after rotator cuff repair (RCR) have been associated with poor clinical results. Meaningful data regarding the role of arthroscopic revision RCR are sparse thus far. PURPOSE/HYPOTHESIS To investigate results after arthroscopic revision RCR. We hypothesized that (1) arthroscopic revision RCR would lead to improved outcomes, (2) the clinical results would be dependent on tendon integrity and (3) tear pattern, tendon involvement, and repair technique would influence clinical and structural results. STUDY DESIGN Case series; Level of evidence 4. METHODS During a 40-month period, 100 patients who underwent arthroscopic revision RCR were prospectively enrolled in this multicenter study. Outcomes were evaluated preoperatively, at 6 months (6M), and at 24 months (24M) using the Constant score (CS), the Oxford Shoulder Score (OSS), and the Subjective Shoulder Value (SSV). Tendon integrity at 2 years was analyzed using magnetic resonance imaging. A total of 13 patients (13%) were lost to follow-up, and 14 patients (14%) had a symptomatic retear before the 24M follow-up. RESULTS All clinical scores improved significantly during the study period (CS: preoperative, 44 ± 16; 6M, 58 ± 22; 24M, 69 ± 19 points; OSS: preoperative, 27 ± 8; 6M, 36 ± 11; 24M, 40 ± 9 points; SSV: preoperative, 43% ± 18%; 6M, 66% ± 24%; 24M, 75% ± 22%) (P < .01). At 2 years, a retear rate of 51.8% (43/83) and a surgical revision rate of 12.6% (11/87) were observed. Mean full-thickness tear size decreased from 5.00 ± 1.61 cm2 to 3.25 ± 1.92 cm2 (P = .041). Although the Sugaya score improved from 4.5 ± 0.9 to 3.7 ± 1.4 (P = .043), tendon integrity did not correlate with better outcome scores. Previous open RCR, involvement of the subscapularis, chondral lesions of Outerbridge grade ≥2, and medial cuff failure were correlated with poorer SSV scores at 2 years (P≤ .047). Patients with traumatic retears had better CS and OSS scores at 2 years (P≤ .039). CONCLUSION Although arthroscopic revision RCR improved shoulder function, retears were frequent but usually smaller. Patients with retears, however, did not necessarily have poorer shoulder function. Patient satisfaction at 2 years was lower when primary open RCR was performed, when a subscapularis tear or osteoarthritis was present, and when the rotator cuff retear was located at the musculotendinous junction. Patients with traumatic retears showed better functional improvement after revision.

Follow-up on a Biological Revision Technique for Large, Recurrent, Retracted, Rotator Cuff Tears. J Am Acad Orthop Surg 2022; 30:e487-e494. [PMID: 34989716 DOI: 10.5435/jaaos-d-21-00556] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Accepted: 11/03/2021] [Indexed: 02/01/2023] Open
Abstract
INTRODUCTION Revision of large recurrent rotator cuff tears by simple repair has a structural failure rate of 40% to 90%. The author presents a minimum 2-year follow-up study of revision rotator cuff reconstructions using a bridging patch graft composed of autogenous biceps tendon saturated with concentrated autologous iliac bone marrow, to determine how the technique compares to the reported outcome of simple repair as a treatment alternative. METHODS The principal entrance criterion was a symptomatic rotator cuff retear with retraction creating a 3- to 5-cm defect. Twenty-five consecutive patients (with an average age of 62 years) were enrolled. Twenty-two (88%) were available for follow-up at 24 to 120 months (mean 68 months) for interview and examination. Questionnaires using Constant, American Shoulder and Elbow Surgeons, and University of California at Los Angeles (UCLA) Shoulder scores were completed. In the terminal 15 patients, the presence of viable marrow mesenchymal cells fixed to the tendon graft at the time of implantation was determined by histological verification. Rotator cuff integrity was evaluated by ultrasonography examination. The Wilcoxon rank-sum test was used to compare nonparametric preoperative with postoperative questionnaire outcome scores. RESULTS Twenty of 22 patients (91%) demonstrated an intact tendon construct. Two of 22 patients (9%) demonstrated structural failure. Viable mesenchymal cells were identified on all graft specimens in high concentration. All patients showed improved results: The mean Constant score increased from 13 to 76; American Shoulder and Elbow Surgeons from 17 to 81; UCLA from 6 to 29 (P < 0.001). DISCUSSION The autogenous graft/marrow technique consistently and successfully reconstructed a large, recurrent rotator cuff tear in a clinical setting where the primary cuff repair had failed. The observation that an autogenous tendon graft saturated with concentrated marrow has the biological potential to reconstruct a difficult soft-tissue defect in the shoulder strongly implies its potential as a reconstructive tool for other soft-tissue defects.

Abstract
BACKGROUND Concomitant full-thickness tear of the subscapularis tendon is often neglected during primary posterosuperior rotator cuff repair, and its significance has not been investigated by any previous clinical study. PURPOSE To investigate (1) the clinical and radiological outcomes of revision arthroscopic rotator cuff repair and (2) the number of neglected concomitant subscapularis full-thickness tears in the revision of posterosuperior rotator cuff retears and their structural integrity after repair. STUDY DESIGN Case series, Level of evidence, 4. METHODS This study retrospectively examined 58 patients who underwent arthroscopic rotator cuff revision for a retear of a previously repaired posterosuperior rotator cuff. Preoperative and postoperative functional scores and active range of motion (ROM) were assessed. The initial and most recent follow-up magnetic resonance imaging scans before revision and arthroscopic findings at the time of primary repair were reviewed to determine whether the concomitant subscapularis tear was newly developed or preexisting. Final confirmation of the tendon's full-thickness tear was made during the revision procedure. RESULTS At final follow-up, mean functional shoulder scores and ROM improved significantly compared with the preoperative values (P < .001). Among the 58 revision cases, 25 (43.1%) had a neglected full-thickness tear of the subscapularis tendon. The fatty infiltration grade of the neglected subscapularis tear progressed from a mean of 1.1 before primary repair to a mean of 1.6 before revision, and the change indicated statistically significant deterioration (P < .001). Despite clinical improvement after revision surgery, the retear rate was considerable in the re-repaired cuff tendons (37.9%) as well as for the repaired concomitant subscapularis tears (24%). CONCLUSION Among revision rotator cuff repairs, 43.1% had neglected subscapularis tears, and fatty infiltration of these initially neglected subscapularis tendons showed further progression at the time of revision. The retear rate after the repair of neglected subscapularis tears was higher than expected. Thus, detecting and treating subscapularis tear via meticulous preoperative evaluation and thorough inspection during primary arthroscopy are essential.

Abstract
The contemporary literature suggests that a primary feature of recurrence of rotator cuff tear after arthroscopic repair is failure of tendon healing, which can occur for multiple reasons, including compromised tissue quality. Recently, the use of augmentation implants, grafts, or scaffolds has emerged as a strategy to address the issue of deficient rotator cuff tissue. A resorbable bio-inductive collagen implant (REGENETEN; Smith & Nephew, Andover, MA) has been shown to increase tendon thickness when applied in rotator cuff repair. This article presents an experienced surgeon's tips for implanting this device. In addition, we review the current literature about this bio-inductive implant.

Abstract
BACKGROUND Primary rotator cuff repairs in complex cases (older patient age, larger tear sizes, chronic tears) and revision repairs are at high risk for failure of healing. PURPOSE To examine clinical outcomes and healing rates in complex and revision rotator cuff repairs with dermal allograft augmentation. STUDY DESIGN Case series; Level of evidence, 4. METHODS A retrospective study was made of cases performed by 3 fellowship-trained surgeons via a uniform technique involving rotator cuff repairs with allograft augmentation. In all cases, a 1.5-mm, human, decellularized dermal graft was tied on top of the tendon at the medial row and compressed to the rotator cuff footprint using a double-row technique. Postoperative magnetic resonance imaging (MRI) was performed at a minimum of 6 months and American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation (SANE), and 12-Item Short Form Health Survey scores were collected at a minimum of 2 years postoperatively. RESULTS A total of 35 patients (23 revision repairs, 12 primary complex repairs) were included. The mean patient age was 57.9 years (range, 41.0-70.5 years). All shoulders had 2-tendon tears (supraspinatus and infraspinatus), and 8 included the upper 50% of the subscapularis. At a minimum of 2 years after surgery (mean, 3.2 years), mean ASES and SANE scores improved from 42.4 and 35.3 to 77.6 and 73.5, respectively (P < .001). In the 23 patients (66%) with postoperative MRI evaluation, 11 (48%) had images showing the tendons were retorn. ASES (89.7 vs 66.4; P = .04) and SANE (84.1 vs 50.5; P = .02) scores were higher in healed patients than those with retears. The retear group had a higher degree of preoperative fatty atrophy of the infraspinatus (P = .024). CONCLUSION Double-row arthroscopic repair with dermal allograft augmentation of complex and revision rotator cuff tears led to improved functional outcomes. Approximately half of patients experienced a failure of healing, which was associated with poorer functional results.

Abstract
Rotator cuff pathology is the most common shoulder condition for which patients seek treatment. Schmidt et al covered the relevant anatomy, natural history, nonsurgical and surgical treatment, biological augmentation, and postoperative rehabilitation in their comprehensive review published in 2015. This current review builds upon the last update, discussing the most recent evidence-based medicine regarding rotator cuff repair: primary repair, revision repair, and reconstructive techniques for superior capsular reconstruction, subacromial balloon spacers, tendon transfer options (pectoralis major, latissimus dorsi, and lower trapezius), and reverse total shoulder arthroplasty.

Revision Rotator Cuff Repair Versus Primary Repair for Large to Massive Tears Involving the Posterosuperior Cuff: Comparison of Clinical and Radiological Outcomes. Orthop J Sports Med 2021; 9:2325967121998791. [PMID: 33959668 PMCID: PMC8060764 DOI: 10.1177/2325967121998791] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Accepted: 12/14/2020] [Indexed: 01/08/2023] Open
Abstract
Background: The retear rate after revision rotator cuff repair (rRCR) ranges from 50% to
90%. Patients who undergo primary RCR (pRCR) for large to massive rotator
cuff tear (mRCT) also have unpredictable outcomes. Purpose: To compare the clinical outcomes after rRCR for a posterosuperior rotator
cuff tear of any size with those after pRCR for mRCT and to identify the
risk factors for poor outcomes and retear after rRCR. Study Design: Cohort study; Level of evidence, 3. Methods: Among patients with posterosuperior cuff tear treated between 2010 and 2017,
the clinical outcomes of 46 patients who underwent rRCR were compared with
106 patients who underwent pRCR for mRCT. Between-group differences in
patient-reported outcomes (visual analog scale [VAS] for pain, VAS for
satisfaction and American Shoulder and Elbow Surgeons [ASES] and Constant
scores) at final follow-up were evaluated and compared with previously
published minimal clinically important difference (MCID) values.
Radiological outcomes were evaluated using magnetic resonance imaging or
ultrasonography at a minimum 1-year follow-up. Multivariate linear
regression analysis was performed to identify the risk factors for poor ASES
score, and multivariate logistic regression analysis was used to assess the
risk factors for retear after rRCR. Results: The mean follow-up was 26.4 months (range, 24-81 months). Although final VAS
for pain, VAS for satisfaction, and ASES scores in the rRCR group were
significantly worse than those in the pRCR group, the Constant score was
similar between the groups. These differences in outcomes did not exceed the
MCID threshold. The retear rate in the rRCR group was 50% compared with 39%
for the pRCR group (P = .194). In the rRCR group, risk
factors for worse ASES score were retear (P = .043;
r = –11.3), lower body mass index (P =
.032; r = 1.9), and lower preoperative VAS for pain
(P = .038; r = 2.3), and risk factors
for retear were preoperative high-grade fatty degeneration (Goutallier
grades 3 and 4) of the supraspinatus muscle (P = .026; odds
ratio, 5.2) and serum hyperlipidemia (P = .035; odds ratio,
11.8). Conclusion: Both study groups had similar clinical and radiological outcomes. Patients
with symptomatic failed rotator cuff repairs having high-grade fatty
degeneration of the supraspinatus muscle and/or serum hyperlipidemia had a
greater likelihood of retear after rRCR.

Abstract
Background. Large, massive irreparable rotator cuff tears lead to a significant decrease in the function of the shoulder joint together with the development of a pronounced pain syndrome. Such injuries are difficult to treat, and the number of relapses, when trying to restore them, is quite high. The installation of a subacromial balloon is the method of choice for this group of patients and allows restoring the function of the shoulder joint fairly successfully. Aim: to evaluate the results of the treatment of patients with massive irreparable rotator cuff tears injuries in a prospective study from 2016 to 2018. Methods. The results of the arthroscopic treatment of large, irreparable rotator cuff injuries in 25 patients (with the average age of 67 5 years) with the installation of a subacromial balloon are presented. In all the clinical cases, there was a pronounced (grades 34, according to the Goutallier classification) fatty dystrophy of the rotator cuff muscles (supraspinatus or in combination with subaspinatus). All the patients underwent the subacromial space release with a thorough bursectomy and subsequent installation of a subacromial balloon. Results. The average score on the UCLA scale was 14 3 points (1117) before the operation and 312 points (2933) 12 months after the operation, the results were considered good and excellent. Conclusion. The results obtained allow us to evaluate the described technique as low-traumatic, simple and fast in its accomplishment, aimed at the reduction of the pain syndrome and restoration of the upper extremity function.

Abstract
Background Arthroscopic rotator cuff repair techniques have almost replaced open repairs. Short- and mid-term studies have shown comparable outcomes, with no clear superiority of either procedure. The aim of this study was to compare the long-term clinical and imaging outcomes following arthroscopic or open rotator cuff repair. Methods Forty patients with magnetic resonance imaging (MRI)–documented, symptomatic supraspinatus or supraspinatus and infraspinatus tears were randomized to undergo arthroscopic or open rotator cuff repair. Clinical and radiographic follow-up was obtained at 6 weeks, 3 months, 1 year, 2 years, and >10 years postoperatively. Clinical assessment included measurement of active range of motion, visual analog scale score for pain, functional scoring according to the Constant-Murley score (CS), and assessment of the Subjective Shoulder Value. Imaging included conventional radiography and MRI for the assessment of cuff integrity and alteration of the deltoid muscle. Results We enrolled 20 patients with a mean age of 60 years (range, 50-71 years; standard deviation [SD], 6 years) in the arthroscopic surgery group and 20 patients with a mean age of 55 years (range, 39-67 years; SD, 8 years) in the open surgery group. More than 10 years’ follow-up was available for 13 patients in the arthroscopic surgery group and 11 patients in the open surgery group, with mean follow-up periods of 13.8 years (range, 11.9-15.2 years; SD, 1.1 years) and 13.1 years (range, 11.7-15 years; SD, 1.1 years), respectively. No statistically significant differences in clinical outcomes were identified between the 2 groups: The median absolute CS was 79 points (range, 14-84 points) in the arthroscopic surgery group and 84 points (range, 56-90 points) in the open surgery group (P = .177). The median relative CS was 94% (range, 20%-99%) and 96% (range, 65%-111%), respectively (P = .429). The median Subjective Shoulder Value was 93% (range, 20%-100%) and 93% (range, 10%-100%), respectively (P = .976). MRI evaluation showed a retear rate of 30% equally distributed between the 2 groups. Neither fatty infiltration of the deltoid muscle, deltoid muscle volume, nor the deltoid origin were different between the 2 groups. Conclusion In a small cohort of patients, we could not document any difference in clinical and radiographic outcomes at long-term follow-up between arthroscopic and open rotator cuff repair. The postulated harm to the deltoid muscle with the open technique could not be confirmed.

Abstract
BACKGROUND There are limited medium- and long-term studies investigating clinical outcomes following revision rotator cuff surgery. The aim of the current study was to analyze the medium-term pain and functional outcomes of a cohort of revision rotator cuff repairs. METHODS This was a multicenter, prospective cohort study of revision rotator cuff repairs undertaken between March 2009 and December 2010. Pain, function (Flex-SF), and postoperative data were collected at baseline; 6, 12, and 24 months; and 5 years. RESULTS A total of 125 revision rotator cuff repairs were included in this study. Average improvement in Flex-SF and pain from baseline to 5 years was 8.5 (P < .001) and 2.1 points, respectively (P < .001). The improvement was not as pronounced as those who underwent primary repair. Significantly lower pain scores were seen in nonsmokers (P < .001) and in those who underwent tenotomy rather than tenodesis (2 vs. 3.5, P < .05) for a damaged long head of biceps. Significantly higher function scores were seen in those with only 1 tendon involved (P < .05). The patient-reported retear rate was 32.6%, and the reoperation rate was 34.7%. CONCLUSION Revision rotator cuff repair provides significant improvement in both pain and function at 5 years postoperation, though not as good as primary repair. Superior clinical outcomes are seen in nonsmokers, those with only 1 tendon affected, and those who undergo tenotomy instead of tenodesis for a damaged long head of biceps tendon.

Abstract
BACKGROUND Revision open rotator cuff repair (ORCR) has been associated with unpredictable functional outcome with concerns of deltoid detachment. The aim of this study was to evaluate the clinical and imaging outcomes of revision ORCR. MATERIALS AND METHODS The study retrospectively reviewed 30 consecutive patients (mean age 60.4 ± 7.2 years) who underwent revision ORCR after failed rotator cuff repair. Pain visual analog scale (VAS), Constant and American Shoulder Elbow Surgeon (ASES) score were assessed preoperatively and at mean 58-month follow-up (range 24-120 months). The acromio-humeral distance (AHD) was measured on pre- and postoperative radiograph. Tear size and fatty infiltration of rotator cuff were evaluated by preoperative magnetic resonance imaging (MRI) study. The retear rate, change of fatty infiltration and deltoid origin integrity were evaluated by postoperative MRI. RESULTS There was significant improvement of pain VAS and functional outcome scores (all p < 0.001). AHD showed no significant change after surgery. On postoperative MRI, the retear rate was 43% (13/30). However, the size of the tendon defect was smaller than that of pre-revision tear (p = 0.006). The patients who had intact tendon had significantly better functional outcomes than those with retear. The intact group had significantly higher AHD both pre- and postoperatively than the retear group. There was no change of fatty infiltration after surgery. Four patients (13%, 4/30) showed thinning of deltoid origin on postoperative MRI, but showed no weakness on clinical examination. CONCLUSION Revision ORCR resulted in improved outcomes in pain relief and shoulder function, with low rate of subclinical deltoid thinning.

Abstract
BACKGROUND The incidence of revision rotator cuff repair (RCR) has increased along with the incidence of primary RCR over the past 2 decades. The purpose of this study was to perform a systematic review to analyze the clinical outcomes of revision RCR and chiefly to identify prognostic factors that may influence postoperative outcomes. METHODS The PubMed, MEDLINE (Ovid), Embase (Elsevier), and Cochrane Library (Wiley) databases were searched from database inception through November 2018 for studies assessing revision RCR. All studies were screened in duplicate for eligibility. Pooled analysis correlations between mean preoperative range-of-motion measures, American Shoulder and Elbow Surgeons (ASES) scores, and visual analog scale (VAS) pain scores and mean postoperative outcomes with revision RCR were examined via linear regression and reported with the strength of the Spearman correlation coefficient (rs). RESULTS A total of 22 studies met the inclusion criteria, including 3 level III and 19 level IV studies. Mean preoperative forward flexion had the greatest correlation with the mean postoperative ASES score (rs = 0.98). A strong positive correlation was also found between mean preoperative forward flexion and mean postoperative forward flexion (rs = 0.83). The mean preoperative VAS pain score was strongly correlated with the mean postoperative VAS pain score (rs = 0.88) and demonstrated a moderate negative association with the mean postoperative ASES score (rs = -0.48). Finally, the mean preoperative ASES score was moderately correlated with the mean postoperative ASES score (rs = 0.56). CONCLUSIONS The results of this systematic review demonstrate favorable clinical outcomes following RCR revision performed both in an open manner and arthroscopically. Preoperative forward flexion was identified as a possible prognostic factor for improved outcomes.

Abstract
PURPOSE Triceps-sparing (TS) approaches have been reported to provide improved triceps strength, better patient outcomes, and a lower incidence of complications in primary total elbow arthroplasty (TEA). It remains unclear whether the advantages of this approach are similar in the revision setting, especially in cases with prior triceps detachment. The purpose of this study was to compare triceps strength and clinical outcomes between TS and triceps-detaching (TD) approaches in revision TEA. METHODS All revision TEAs performed over a 17-year period with a minimum 1-year follow-up were retrospectively reviewed. Elbows with preoperative triceps insufficiency or subsequent component removal for infection were excluded. Patients were grouped according to the surgical approach performed at the last revision TEA. Outcome measures included triceps strength, range of motion, visual analog scale (VAS), Mayo Elbow Performance Score (MEPS), and Disabilities of the Arm, Shoulder, and Hand (DASH) scores. RESULTS Ten TS and 6 TD elbows were evaluated. Four elbows within the TS group had documented TD surgery prior to revision. Median follow-up was longer in the TD group (137 ± 75 months vs 53 ± 20 months). Functional strength and DASH scores were significantly better in the TS group. Arc of motion, VAS, and MEPS were similar between the TS and the TD groups. CONCLUSIONS The TS approach preserves greater postoperative functional triceps strength after revision TEA, regardless of the type of approach used previously.

Abstract
PURPOSE To evaluate the clinical success rate, along with risk factors for failure, in patients undergoing latissimus dorsi transfer for the treatment of massive, irreparable, previously failed rotator cuff tears. METHODS We performed a retrospective chart review of prospectively collected data from an institutional shoulder outcome registry. All patients who underwent latissimus dorsi transfer for previously failed rotator cuff repair between 2006 and 2013 with a minimum follow-up period of 1 year were included in the study. The indications for inclusion were large (≥2 tendons), retracted, chronic rotator cuff tears with fatty infiltration or atrophy for which prior surgical repair had failed. Preoperative and postoperative American Shoulder and Elbow Surgeons (ASES) and Simple Shoulder Test scores were collected, along with postoperative Single Assessment Numerical Evaluation scores. Complications and clinical failures (Δ in ASES score <17) were recorded. Patient demographic and tear characteristics were evaluated as potential risk factors for failure. RESULTS A total of 22 patients (mean age, 53 ± 6 years) were included in the study, with a mean follow-up time of 3.4 ± 1.1 years. Over 63% of patients (n = 14) reported undergoing 2 or more prior failed rotator cuff repairs. Patients undergoing latissimus dorsi transfer showed significant improvements in ASES scores (from 35.2 ± 21.9 preoperatively to 55.8 ± 22.9 postoperatively, P = .001), Simple Shoulder Test scores (from 3.5 ± 3.1 preoperatively to 5.2 ± 3.4 postoperatively, P = .002), and pain scores (from 5.9 ± 2.8 preoperatively to 4.6 ± 4.3 postoperatively, P = .002) at final follow-up. The complication rate after latissimus transfer was 27%. The rate of revision to reverse total shoulder arthroplasty was 13.6% (n = 3) after a mean of 2.7 years, and the clinical failure rate was 41% (n = 9) at final follow-up. An acromiohumeral interval of less than 7 mm (P = .04) and high-grade fatty infiltration (grade 3 or greater, P = .004) were significant preoperative risk factors for clinical failure. CONCLUSIONS Latissimus dorsi tendon transfer resulted in a clinical failure rate of 41% and complication rate of 27%, with an acromiohumeral interval of less than 7 mm and high-grade fatty infiltration being associated with postoperative failure. LEVEL OF EVIDENCE Level IV.

Biomechanical Analysis of Medial-Row All-Suture Suture Anchor Fixation for Rotator Cuff Repair in a Pair-Matched Cadaveric Model. Arthroscopy 2019; 35:1370-1376.

Abstract
PURPOSE To compare the biomechanical properties of all-suture suture anchors (ASSAs) with conventional suture anchors (CSAs) for double-row rotator cuff repair (RCR). METHODS Fourteen fresh-frozen human cadaveric shoulders were randomized into 2 RCR treatment groups: ASSA and CSA. All constructs received a double-row repair, with the lateral-row implants consisting of two 5.5-mm PEEK (polyether ether ketone) Footprint anchors. Each construct was loaded to a 10-N preload for 2 minutes, followed by cyclic loading from 10 to 160 N at a rate of 100 N/s for 100 cycles. Load-to-failure testing was performed immediately after cyclic loading testing at 1 mm/s from the zero position until failure. Cyclic creep, elongation amplitude, maximum load, stiffness, energy, and failure mode were recorded. RESULTS No significant difference in cyclic creep (P = .117) or elongation amplitude (P = .428) was found between the ASSA and CSA groups during cyclic testing. Three specimens in each group (43% in each) failed by the suture tearing through the tendon. The remaining specimens in each group failed by the anchor pulling out of the humeral head. The mean maximum load was 617.73 ± 177.77 N and 545.13 ± 212.98 N for the ASSA and CSA groups, respectively (P = .339). Maximum elongation before failure was not different between groups (P = .122). Mean energy and stiffness were not statistically different between the ASSA and CSA groups (P = .629 and P = .973, respectively). CONCLUSIONS In this cadaveric analysis with a simplified unidirectional experimental setup, failure mechanics and maximum load between the ASSA and CSA constructs were similar, with no difference in energy and stiffness. Although the ASSA group showed slightly larger elongation than the CSA group, these differences may not be clinically relevant. CLINICAL RELEVANCE This study provides a biomechanical head-to-head comparison of ASSAs and CSAs, indicating that ASSAs may be clinically equivalent to CSAs for use in an RCR.

Abstract
BACKGROUND The retear rate after primary rotator cuff (RC) reconstruction is high and commonly leads to poorer clinical outcomes and shoulder function. In the case of primary failure, revision RC reconstruction (RCR) has become increasingly important to re-create RC integrity and improve outcomes. To date, clinical and structural outcomes after RCR have not been sufficiently investigated and described at midterm follow-up. Hypothesis/Purpose: The purpose was to evaluate the clinical and radiological outcomes after revision RCR. It was hypothesized that revision RCR significantly improves clinical outcomes and that the outcomes positively correlate with tendon integrity on magnetic resonance imaging (MRI). STUDY DESIGN Case series; Level of evidence, 4. METHODS Patients who underwent revision RCR between 2008 and 2014 were retrospectively evaluated with a minimum follow-up of 2 years. Outcomes were assessed by a clinical examination, a visual analog scale for pain (VAS), the Constant Score (CS), the American Shoulder and Elbow Surgeons (ASES) score, and the Disabilities of the Arm, Shoulder and Hand (DASH) score. Tendon integrity was determined using 3-T MRI and graded according to the Sugaya classification. RESULTS Thirty-one of 40 patients (77.5%) were available for the final assessment at a mean follow-up of 50.3 ± 20.4 months. Clinical outcome scores significantly improved from preoperatively to postoperatively for the CS (39.7 ± 16.7 to 65.1 ± 19.7; P < .001), ASES (44.2 ± 17.7 to 75.2 ± 24.8; P < .001), and DASH (68.6 ± 15.1 to 21.5 ± 19.1; P < .001). The VAS score decreased from 6.1 ± 1.8 preoperatively to 1.3 ± 1.8 at final follow-up ( P < .001). MRI demonstrated a retear rate of 55.5%. No differences in CS, ASES, and DASH scores were detected between patients with an intact repair and failure. Abduction strength was not significantly different in patients with an intact repair and retears (55.5 N vs 44.0 N, respectively, P = .52). CONCLUSION Revision RCR improves clinical outcomes and shoulder function at midterm follow-up. The clinical outcome scores were comparable in patients with an intact repair and those with failed RC healing. Therefore, tendon integrity was not correlated with better clinical outcomes after revision RCR at final follow-up.

Abstract
Retears of the rotator cuff, following operative repair, is not an uncommon event. Various factors have been shown to influence recurrence including the technique of repair. Multiple techniques have been performed with varying results and complications. The repair technique significantly affects the rate and pattern of retears. Although risk of retears with double row and suture bridge techniques is relatively low, medial cuff failure is a potential complication which poses significant challenges when revision repair is undertaken. Modifications in surgical techniques in, both, double row and suture bridge repairs can help decrease the risk of medial cuff failure. Thorough analysis of retear rates and patterns reported, and their relation with the repair technique, provides new insights about the pathogenesis of rotator cuff retears, their future prevention and appropriate management.

Abstract
BACKGROUND The purpose was to assess the minimum 2-year patient-reported outcomes and failure rate of patients who underwent revision arthroscopic rotator cuff repair augmented with acellular human dermal matrix (AHDM) allograft for repairable retears. METHODS From 2008-2014, patients who underwent revision rotator cuff repair augmented with AHDM with greater than 2 years' follow-up by a single surgeon were retrospectively reviewed. Data regarding surgical history, demographic characteristics, and medical comorbidities were collected. Outcome data included American Shoulder and Elbow Surgeons (ASES) and Single Assessment Numeric Evaluation (SANE) scores, as well as rotator cuff healing on magnetic resonance imaging or ultrasound. Retears and subsequent surgical procedures were characterized. RESULTS A total of 28 patients met our inclusion criteria, and 23 (82%) were available for follow-up at 2 years. The mean age was 60.1 ± 9.3 years (range, 43-79 years), with a mean follow-up period of 48 ± 23 months. All patients had at least 1 prior rotator cuff repair. Of the 23 patients, 13 (56%) underwent postoperative imaging, and 4 of these 13 (31%) had a retear. A reoperation was performed in 3 of 23 patients (13%). Among the 6 patients with both preoperative and postoperative outcome scores, we saw improvement in the ASES score from 56 to 85 (P = .03) and in the SANE score from 42 to 76 (P = .03). The full cohort's mean postoperative ASES and SANE scores were 77 and 69, respectively. CONCLUSION AHDM allograft augmentation is a safe and effective treatment method for patients with full-thickness rotator cuff retears. Further research is needed with larger studies to confirm these findings from our small cohort of patients.

Abstract
OBJECTIVE To evaluate whether augmentation grafts using autologous fascia lata improve functional results for rotator cuff repairs and reduce the retear rate compared to those without augmentation. MATERIAL AND METHODS This is a prospective evaluation comprising 20 patients with a complete symptomatic rotator cuff tear. The operations were carried out from a superior approach performing a total cuff repair, for 10 patients we used a suture augmented with an autologous graft taken from their own fascia lata while unaugmented sutures were used for the other 10 patients. The follow-up period lasted for one year post-intervention. We measured variables for tear type, functionality and pain, both baseline and at 6 and 12-month follow ups. We evaluated retear incidence in each group as well as each group's pain and functionality response. RESULTS The improved pain levels in the non-graft group evolved gradually over time. Conversely, in the group with the augmentation grafts, average Constant-Murley shoulder outcome scores at six months were already above 10 and were maintained at 12 months. One retear occurred in the graft group and 2 in the group without grafts, thus presenting no significant differences. There were no significant changes in pain and function values at the one year follow up in either group. CONCLUSION Our preliminary results regarding rotator cuff augmentation surgery with autologous fascia lata showed a significant improvement in pain levels after 6 months compared to the patients with no augmentation, who required 12 months to reach the same values. After a year of follow up, there were no differences between the mean Constant and pain scores in either intervention group The number of retears in the non-graft group was greater than that in the group with grafts although the difference was not significant.

[PMID: 29202746 PMCID: PMC5715556 DOI: 10.1186/s12891-017-1874-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2017] [Accepted: 11/24/2017] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND Although a loss of rotator cuff integrity leads to the superior migration of the humeral head, the parameters that characterize the anterolateral migration of the humeral head have not been established. The purpose of this study was to investigate the correlation between the translation of the humeral head scale (T-scale) and clinical outcomes of rotator cuff repair, as well as the correlation between the T-scale and radiologic parameters. METHODS One hundred thirty-five consecutive patients with full-thickness rotator cuff tears underwent primary rotator cuff repair. The T-scale, which indicates the distance from the center of the humeral head to the lateral coracoacromial arch, was measured on axial computed tomography scans, and the acromiohumeral interval (AHI) was measured radiographically. The correlation of the two parameters with the clinical scores of the Japanese Orthopaedic Association and University of California-Los Angeles scores and active forward elevation (FE) were evaluated at the preoperative and postoperative stages, respectively. RESULTS The postoperative T-scale and AHI correlated well with the postoperative FE and clinical scores in the patients with large-massive tears but not in those patients with small-medium tears and preoperative large-massive tears. A significant correlation was observed between the postoperative T-scale and AHI. The T-scale was subject to cuff repair integrity. CONCLUSIONS We demonstrated that the postoperative T-scale was well correlated with the clinical results and postoperative AHI after rotator cuff repair for large-massive tears, indicating that poor outcomes are associated with combined superior and anterolateral migration of the humeral head following retears.

Characterizing the macro and micro mechanical properties of scaffolds for rotator cuff repair. J Shoulder Elbow Surg 2017; 26:2038-2046. [PMID: 28865966 DOI: 10.1016/j.jse.2017.06.035] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2017] [Revised: 05/18/2017] [Accepted: 06/19/2017] [Indexed: 02/01/2023]
Abstract
BACKGROUND Retearing after rotator cuff surgery is a major clinical problem. Numerous scaffolds are being used to try to reduce retear rates. However, few have demonstrated clinical efficacy. We hypothesize that this lack of efficacy is due to insufficient mechanical properties. Therefore, we compared the macro and nano/micro mechanical properties of 7 commercially available scaffolds to those of the human supraspinatus tendons, whose function they seek to restore. METHODS The clinically approved scaffolds tested were X-Repair, LARS ligament, Poly-Tape, BioFiber, GraftJacket, Permacol, and Conexa. Fresh frozen cadaveric human supraspinatus tendon samples were used. Macro mechanical properties were determined through tensile testing and rheometry. Scanning probe microscopy and scanning electron microscopy were performed to assess properties of materials at the nano/microscale (morphology, Young modulus, loss tangent). RESULTS None of the scaffolds tested adequately approximated both the macro and micro mechanical properties of human supraspinatus tendon. Macroscale mechanical properties were insufficient to restore load-bearing function. The best-performing scaffolds on the macroscale (X-Repair, LARS ligament) had poor nano/microscale properties. Scaffolds approximating tendon properties on the nano/microscale (BioFiber, biologic scaffolds) had poor macroscale properties. CONCLUSION Existing scaffolds failed to adequately approximate the mechanical properties of human supraspinatus tendons. Combining the macroscopic mechanical properties of a synthetic scaffold with the micro mechanical properties of biologic scaffold could better achieve this goal. Future work should focus on advancing techniques to create new scaffolds with more desirable mechanical properties. This may help improve outcomes for rotator cuff surgery patients.

Clinical outcome and prognostic factors of revision arthroscopic rotator cuff tear repair. Knee Surg Sports Traumatol Arthrosc 2017; 25:2157-2163. [PMID: 28035424 DOI: 10.1007/s00167-016-4392-7] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2015] [Accepted: 12/01/2016] [Indexed: 10/20/2022]
Abstract
PURPOSE The aim of this study was to evaluate the clinical outcome of arthroscopic rotator cuff revision surgery in a cohort of patients and to identify prognostic factors for this procedure. METHODS Fifty-one consecutive patients undergoing revision arthroscopic rotator cuff repair were prospectively followed over a minimum period of one year. Radiologic findings and clinical data regarding primary and revision surgery were collected. Clinical evaluation was performed pre- and post-operatively by means of Constant Score and Simple Shoulder Test. RESULTS Median age at the time of revision surgery was 60 years (range 36-77 years). Median follow-up was 25 months (range 12-58 months). There were 17 men (33.3%) and 34 women (66.7%). The majority of the tears affected the supraspinatus tendon alone (51%) or both the supra- and infraspinatus tendons (35.3%). Significant improvements were seen in terms of active forward elevation, active external rotation, pain, Simple Shoulder Test score, Constant Score, and post-operative satisfaction-age, gender, and time to revision surgery did not show significant predictive value. A smaller tear size and pre-operative elevation greater than 90° were demonstrated to be independent prognostic factors for better outcome. However, the mean increase in Constant Score was not related to the size of the tear, range of motion, or age. CONCLUSION The results of this study indicate that arthroscopic revision rotator cuff repair results in reliable improvement in shoulder function, pain, and satisfaction. Pre-operative active range of motion and tear size seem to determine final outcome. A similar increase in mean Constant Score can be achieved even in large tears in patients aged over 65 years.

Abstract
AIMS Advances in arthroscopic techniques for rotator cuff repair have made the mini-open approach less popular. However, the mini-open approach remains an important technique for repair for many surgeons. The aims of this study were to compare the integrity of the repair, the function of the shoulder and satisfaction post-operatively using these two techniques in patients aged > 50 years. PATIENTS AND METHODS We identified 22 patients treated with mini-open and 128 patients treated with arthroscopic rotator cuff repair of July 2007 and June 2011. The mean follow-up was two years (1 to 5). Outcome was assessed using the American Shoulder and Elbow Surgeons (ASES) and Simple Shoulder Test (SST) scores, and satisfaction. The integrity of the repair was assessed using ultrasonography. A power analysis ensured sufficient enrolment. RESULTS There was no statistically significant difference between the age, function, satisfaction, or pain scores (p > 0.05) of the two groups. The integrity of the repair and the mean SST scores were significantly better in the mini-open group (91% of mini-open repairs were intact versus 60% of arthroscopic repairs, p = 0.023; mean SST score 10.9 (standard deviation (sd) 1.3) in the mini-open group; 8.9 (sd 3.5) in arthroscopic group; p = 0.003). The ASES scores were also higher in the mini-open group (mean ASES score 91.0 (sd 10.5) in mini-open group; mean 82.70 (sd 19.8) in the arthroscopic group; p = 0.048). CONCLUSION The integrity of the repair and function of the shoulder were better after a mini-open repair than after arthroscopic repair of a rotator cuff tear in these patients. The functional difference did not translate into a difference in satisfaction. Mini-open rotator cuff repair remains a useful technique despite advances in arthroscopy.

Abstract
INTRODUCTION AND OBJECTIVES Rotator cuff re-ruptures appear in 38-65% of cases. In order to reduce this rate, many studies have been performed using different types of biomaterial for purely mechanical aims (re-inforce the suture) and/or biological agents (growth factor transporterts). The aim of this study is to review 22 cases treated with xenografts and analyse various current alternatives. MATERIALS AND METHODS A descriptive and retrospective study was conducted using the variables of age, sex, laterality, time of surgery, involvement in MRI, number of anchors, and final mobility results on the Constant and the University of California Los Angeles (UCLA) validated scales. RESULTS The study included 22 patients, with a mean age of 51.7±4.6 years. A mean of 2 anchors were used and 13 patients were treated with a porcine intestinal submucosa implant, 6 with equine pericardium, and 3 with porcine dermis. Final results were: 37.6±13 points for the Constant test, and 16.9±3.9 points on the UCLA scale. The follow up was 36±10.2 months. CONCLUSIONS In our experience, xenografts could provide good functional results and they would be a surgical alternative to tendon transfers in cases of massive tears. Further studies should be conducted with other biomaterials.

Abstract
This is a consensus statement on rehabilitation developed by the American Society of Shoulder and Elbow Therapists. The purpose of this statement is to aid clinical decision making during the rehabilitation of patients after arthroscopic rotator cuff repair. The overarching philosophy of rehabilitation is centered on the principle of the gradual application of controlled stresses to the healing rotator cuff repair with consideration of rotator cuff tear size, tissue quality, and patient variables. This statement describes a rehabilitation framework that includes a 2-week period of strict immobilization and a staged introduction of protected, passive range of motion during weeks 2-6 postoperatively, followed by restoration of active range of motion, and then progressive strengthening beginning at postoperative week 12. When appropriate, rehabilitation continues with a functional progression for return to athletic or demanding work activities. This document represents the first consensus rehabilitation statement developed by a multidisciplinary society of international rehabilitation professionals specifically for the postoperative care of patients after arthroscopic rotator cuff repair.

Abstract
Importance Recurrent tear after rotator cuff repair (RCR) is common. Conservative, and open and arthroscopic revisions, have been advocated to treat these failures. Aim or objective The purpose of this systematic review was to evaluate the different options for managing recurrent rotator cuff tears. Evidence review A search was conducted of level I through 4 studies from January 2000 to October 2015, to identify studies reporting on failed RCR. 10 articles were identified. The overall quality of evidence was very low. Findings Mid-term to long-term follow-up of patients treated conservatively revealed acceptable results; a persistent defect is a well-tolerated condition that only occasionally requires subsequent surgery. Conservative treatment might be indicated in most patients, particularly in case of posterosuperior involvement and poor preoperative range of motion. Revision surgery might be indicated in a young patient with a repairable lesion, a 3 tendon tear, and in those with involvement of the subscapularis. Conclusions and relevance The current review indicates that arthroscopic revision RCR can lead to improvement in functional outcome despite a high retear rate. Further studies are needed to develop specific rehabilitation in the case of primary rotator cuff failure, to better understand the place of each treatment option, and, in case of repair, to optimise tendon healing.

Platelet-Rich Plasma Reduces Retear Rates After Arthroscopic Repair of Small- and Medium-Sized Rotator Cuff Tears but Is Not Cost-Effective. Am J Sports Med 2015; 43:3071-6.

Abstract
BACKGROUND It has been suggested that platelet-rich plasma (PRP) improves healing after arthroscopic rotator cuff repair. The current literature provides ample but inconsistent data on this topic. PURPOSE To systematically review the current in vivo evidence for the use of platelet concentrates (PRP) in the arthroscopic treatment of rotator cuff tears to assess effectiveness, safety, and cost-effectiveness. STUDY DESIGN Meta-analysis and cost-effectiveness analysis. METHODS Published evidence from controlled, human trials of rotator cuff repair augmented with platelet concentrates was systematically gathered, and data on retear rates were extracted. Mathematical and clinical heterogeneity was evaluated, and fixed-effect meta-analysis was performed to calculate the risk ratio (RR) of retears and the number needed to treat (NNT). Subgroup analyses were made for small/medium tears (n = 404) and large/massive tears (n = 374). Cost-effectiveness was assessed using data from this meta-analysis and using cost data from the literature, including extensive sensitivity analyses, to calculate the incremental cost-effectiveness ratio (ICER). RESULTS Thirteen studies published between 2010 and 2014 were identified for analysis. The RR for retear for all patients was 0.87 (95% CI, 0.67-1.12; P = .286). For small- and medium-sized tears (<3 cm), the RR for retear was 0.60 (95% CI, 0.37-0.97), consistent with a significant difference in favor of PRP use (P = .038). This translated into an NNT of 14 (95% CI, 7-125). However, at an ICER of US$127,893 per quality-adjusted life year gained, assuming a 5% revision rate, the use of PRP was not cost-effective for small- and medium-sized tears. CONCLUSION In large tears, even with double-row repair, the beneficial effects of PRP alone are insufficient to compensate the progressed tissue damage. The study data suggest that PRP may promote healing of small- and medium-sized tears to reduce retear rates. However, despite the substantial biological effect, at current cost, the use of PRP is not cost-effective in arthroscopic repair of small- and medium-sized tears.

Abstract
This study compared the clinical outcomes following mini-open rotator cuff repair (MORCR) between early mobilisation and usual care, involving initial immobilisation. In total, 189 patients with radiologically-confirmed full-thickness rotator cuff tears underwent MORCR and were randomised to either early mobilisation (n = 97) or standard rehabilitation (n = 92) groups. Patients were assessed at six weeks and three, six, 12 and 24 months post-operatively. Six-week range of movement comparisons demonstrated significantly increased abduction (p = 0.002) and scapular plane elevation (p = 0.006) in the early mobilisation group, an effect which was not detectable at three months (p > 0.51) or afterwards. At 24 months post-operatively, patients who performed pain-free, early active mobilisation for activities of daily living showed no difference in clinical outcomes from patients immobilised for six weeks following MORCR. We suggest that the choice of rehabilitation regime following MORCR may be left to the discretion of the patient and the treating surgeon.

Abstract
Rotator cuff repairs have increased. Although clinical trials have examined the effect of immobilization and timing of passive range of motion (ROM) on patient outcomes and structural integrity, there is controversy as to the timing and progression for therapy. Primary goals are restoring function while maintaining the structural integrity of the repair. We advocate for a protocol of 4 to 6 weeks of immobilization, followed by protected passive ROM, which is followed by a gradual progression to active ROM and then appropriate resistance exercise program for most all rotator cuff repairs. The rate of progression should be adjusted individually.

Efficacy of informed versus uninformed physiotherapy on postoperative retear rates of medium-sized and large rotator cuff tears. J Shoulder Elbow Surg 2015; 24:1413-20.

Abstract
BACKGROUND It is important to perform the first 12 weeks of rehabilitation without risk of tearing a cuff tendon from its repair site. Our hypothesis was that performing early postoperative rehabilitation with a limitable pendulum exercise device can produce lower retear rate outcomes when it is combined with safe, informed physiotherapy compared with a standardized protocol of rehabilitation performed at home. METHODS By using an asymmetric arm support brace and an advanced accelerometer, we attempted to determine the benefits of small pendulum exercises (proposed by Long et al). This study enrolled 24 patients to use a monitoring device in standardized small pendulum exercises. Clinical outcomes and magnetic resonance images were evaluated preoperatively and 12 weeks after surgery. RESULTS While a patient performed pendulum exercises, a therapist used computer imagery to observe whether vertical acceleration was over a given threshold (identified as physiologic tremors), as a warning of and precaution associated with the increased risk of repair failure. Similar self-reported functional outcomes were reported in 2 areas. The rate of recurrent tears was significantly higher for both the medium-sized and large areas in the uninformed home rehabilitation group compared with the informed group. CONCLUSION The results of monitoring of pendulum exercises to develop informed physical therapeutic methodology were consistent with those of previously published literature. In this study, use of a monitoring device during early rehabilitation was associated with lower retear rates after rotator cuff repair.

Abstract
BACKGROUND The incidence of failed rotator cuff repairs remains high, especially in the setting of massive tears or revision repairs. The purpose of this study was to evaluate patient outcomes and repair integrity after augmentation with the repair patch, a poly-l-lactide synthetic polymer. METHODS Sixteen consecutive patients with massive or recurrent rotator cuff tears underwent open repair with synthetic poly-l-lactide patch augmentation. Two patients required the patch to bridge defects, and 1 patient retore after a motor vehicle accident and had revision surgery at another institution. The 13 remaining patients were retrospectively evaluated from 1.2 to 1.7 years (average, 1.5 years) after surgery by PENN, American Shoulder and Elbow Surgeons, and Single Assessment Numeric Evaluation scores. Magnetic resonance imaging was used to examine the integrity of the repair at a minimum of 1 year of follow-up. RESULTS The mean age was 57.3 years (42-68 years). Five patients (38%) had an intact rotator cuff at the time of follow-up. The remaining patients (62%) had full-thickness tears. PENN scores significantly improved from a preoperative score of 50.9 to 77.6 (P < .005). American Shoulder and Elbow Surgeons scores significantly improved from 32.8 to 74.2 (P = .0001). Single Assessment Numeric Evaluation scores at latest follow-up were 76.2. CONCLUSION Poly-l-lactide repair patch augmentation of massive and recurrent large to massive rotator cuff tears demonstrates significant improvement in shoulder outcome measures for this difficult population, despite a retear rate of 62%. Further investigation with larger, prospective long-term studies is needed to determine whether this technique provides a true benefit compared with traditional, nonaugmented repair.

Abstract
BACKGROUND Early passive range of motion (ROM) following arthroscopic cuff repair is thought to decrease postoperative stiffness and improve functionality. However, early aggressive rehabilitation may compromise repair integrity. Our purpose was to perform a systematic review to determine if there are differences between early and delayed rehabilitation after arthroscopic rotator cuff repair in terms of clinical outcomes and healing. METHODS We performed a literature search with the terms 'arthroscopic rotator cuff', 'immobilization', 'early', 'delayed', 'late', and 'rehabilitation' using PubMed, Cochrane Central Register of Controlled Trials, and EMBASE. Selection criteria included: level I/II evidence ≤ 6 months in duration, comparing early versus delayed rehabilitation following arthroscopic repair. Data regarding demographics, sample sizes, duration, cuff pathology, surgery, rehabilitation, functional outcomes, pain, ROM and anatomic assessment of healing were analyzed. PRIMSA criteria were followed. RESULTS We identified six articles matching our criteria. Three reported significantly increased functional scores within the first 3-6 months with early rehabilitation compared to the delayed group, only one of which continued to observe a difference at a final follow-up of 15 months. Four articles showed improved ROM in the first 3-6 months post-operatively with early rehabilitation. One noted transient differences in pain scores. Only one study noted significant differences in ROM at final follow-up. No study reported any significant difference in rates of rotator cuff re-tear. However, two studies noted a trend towards increased re-tear with early rehabilitation that did not reach significance. This was more pronounced in studies including medium-large tears. CONCLUSIONS Early rehabilitation after arthroscopic cuff repair is associated with some initial improvements in ROM and function. Ultimately, similar clinical and anatomical outcomes between groups existed at 1 year. While there was no significant difference between groups in anatomic failure of the repaired cuff, there may be a trend towards increased re-tear with larger tears.

Abstract
The goal of this study was to review the authors' initial experience with arthroscopic transosseous rotator cuff repair. Thirty-one patients with full-thickness rotator cuff tears underwent arthroscopic transosseous rotator cuff repair over a 15-month period. Preoperatively, demographics and subjective scores were recorded. Postoperatively, pain levels, subjective shoulder values, satisfaction scores, American Shoulder and Elbow Surgeons (ASES) scores, complications, and reoperations were noted with a minimum 2-year follow-up. The relationships between pre- and intraoperative variables and outcome scores were determined with univariate analysis. Average patient age was 56 years, and 23 patients (74%) were men. Twenty patients (65%) underwent primary rotator cuff repair, and 11 patients (35%) underwent revision repair. Average time to follow-up was 26 months. Average preoperative pain level and subjective shoulder value were 5.1 of 10 and 35%, respectively. Average postoperative scores included pain level of 0.9 of 10, subjective shoulder value of 84%, satisfaction score of 90.6 of 100, and ASES score of 86.3 of 100. There were 3 (9.7%) major and 2 (6%) minor complications. Patients undergoing revision rotator cuff repair had significantly worse outcomes (pain level, subjective shoulder value, ASES score; P<.05) compared with those undergoing primary repair, and cortical augmentation did not significantly affect outcome. Overall, outcomes after arthroscopic transosseous rotator cuff repair are good, although patients undergoing revision repair do not have the same outcomes as those undergoing primary cuff repair. The procedure is not without complications (9.7% major, 6% minor complications). Cortical augmentation may be used to supplement fixation, although it does not necessarily affect outcomes. Patients without such augmentation may be at increased risk for suture cutout through the bone.

Abstract
Outcomes following revision surgery for failed rotator cuff repairs are far less predictable than and are associated with decreased patient satisfaction compared with primary repairs. Extracellular matrix augmentation (ECM) may improve the biologic potential for healing during revision repair. The authors examined clinical outcomes and healing rates based on postoperative imaging of patients who underwent revision open rotator cuff repair with an ECM patch for symptomatic recurrent rotator cuff tear. Twenty-four (77%) of 31 patients with a mean follow-up of 50 months (range, 30-112 months) completed post-revision surgery outcome questionnaires at a mean of 5.3 years after revision surgery, and 16 patients (67%) underwent a physical examination and repeat imaging (ultrasound or magnetic resonance imaging) at a mean of 4.2 years after revision surgery. Ten (63%) of those 16 patients were found to have failed revision rotator cuff repair on imaging, with American Shoulder and Elbow Surgeons (ASES) outcome measures that were significantly (P=.04) better in patients with confirmed intact repairs than those with confirmed failed revision repair. Outcome measures for all patients (n=24) included a mean ASES score of 67.2 (SD, 27.9) and a mean Single Assessment Numeric Evaluation (SANE) score of 66.9 (SD, 26.0). Based on these scores, excellent results were achieved in 24% of patients, good in 13%, fair in 21%, and poor in 42%. Results of this investigation demonstrated that augmentation of revision rotator cuff repair with an ECM patch through an open approach showed no significant improvement in outcomes when compared to historical reports without augmentation.

Abstract
Rotator cuff repair (RCR) is a common procedure performed by orthopedic surgeons via arthroscopic, open, or mini-open techniques. While this surgery is considered to be of low morbidity, several potential complications can arise either intraoperatively or during the postoperative time period. Some of these complications are related to the surgical approach (arthroscopic or open), while others are patient dependent. Many of these complications can be managed through nonoperative means; however, early recognition and timely treatment is essential in limiting the long-term sequela and improving patient outcome. There are several different ways to classify complications after RCR repair: timing, severity, preventability, whether or not the pathology is intra- or extra-articular, and the type of treatment necessary. It is essential that the surgeon is cognizant of the etiology contributing to the failed RCR surgery in order to provide timely and proper management.

Abstract
BACKGROUND The arthroscopic suture-bridge technique has proved to provide biomechanically firm fixation of the torn rotator cuff to the tuberosity by increasing the footprint contact area and pressure. However, a marginal dog-ear deformity is encountered not infrequently when this technique is used, impeding full restoration of the torn cuff. PURPOSE To evaluate the structural and functional outcomes of the use of a modified suture-bridge technique to prevent a marginal dog-ear deformity compared with a conventional suture-bridge method in rotator cuff repair. STUDY DESIGN Cohort study; Level of evidence 2. METHODS A consecutive series of 71 patients aged 50 to 65 years who underwent arthroscopic rotator cuff repair for full-thickness medium-sized to massive tears was evaluated. Patients were divided into 2 groups according to repair technique: a conventional suture-bridge technique (34 patients; group A) versus a modified suture-bridge technique to prevent a marginal dog-ear deformity (37 patients; group B). Radiographic evaluations included postoperative cuff integrity using MRI. Functional evaluations included pre- and postoperative range of motion (ROM), pain visual analog scale (VAS), the University of California, Los Angeles (UCLA) shoulder rating scale, the Constant score, and the American Shoulder and Elbow Surgeons (ASES) score. All patients were followed up clinically at a minimum of 1 year. RESULT When the 2 surgical techniques were compared, postoperative structural integrity by Sugaya classification showed the distribution of types I:II:III:IV:V to be 4:20:2:4:4 in group A and 20:12:4:0:1 in group B. More subjects in group B had a favorable Sugaya type compared with group A (P < .001). The postoperative healed:retear rate was 26:8 in group A and 36:1 in group B, with a significantly lower retear rate in group B (P = .011). However, there were no significant differences in ROM and all functional outcome scores between the 2 groups postoperatively. When surgical techniques were compared across healed (n = 62) and retear (n = 9) groups, significantly fewer modified suture-bridge technique repairs were found in the retear group (P = .03). There were significant differences between healed and retear groups in functional outcome scores, with worse results in the retear group. CONCLUSION A modified suture-bridge technique to prevent a marginal dog-ear deformity provided better structural outcomes than a conventional suture-bridge technique for medium-sized to massive rotator cuff tears. This technique may ultimately provide better functional outcomes by decreasing the retear rate.
