Long-term outcome of arthroscopic debridement of massive irreparable rotator cuff tears

Revision rates and progression to shoulder arthroplasty after arthroscopic repair of massive rotator cuff tears

PURPOSE

The purpose of this systematic review was to assess the rate of progression to reverse total shoulder arthroplasty (RTSA) and to other interventions as revision surgeries after an arthroscopic repair of a massive rotator cuff tear (MRCT). Additionally, the review aimed at defining the best arthroscopic approach for the treatment of MRCTs in terms of failure and revision rates.

METHODS

The purpose of this systematic review and meta-analysis was to evaluate the rates of progression to reverse total shoulder arthroplasty in patients who underwent primary arthroscopic repair of an MRCT with different arthroscopic procedures. A meta-analysis was performed to compare the rate of progression to revision surgery and reverse total shoulder arthroplasty.

RESULTS

Eighteen articles were included in the qualitative synthesis and 14 articles were included in the meta-analysis. Overall, 934 patients and 950 shoulders were involved in the review. Seven-hundred and thirty patients and 735 shoulders were included in the meta-analysis. The proportion of revisions to reverse total shoulder arthroplasty was 0.9%, 3.3% and 0.1% for complete repair, partial repair and superior capsular reconstruction, respectively. No statistically significant differences were found across the groups in terms of progression to reverse total shoulder arthroplasty (n.s.). The average proportions of revisions to interventions different than reverse total shoulder arthroplasty. were 0.9% for complete repair, 2.0% for partial repair and 2.0% for superior capsular reconstruction again, no statistically relevant difference was found among the groups (n.s.).

CONCLUSIONS

The current review finds no statistically significant differences in the progression to reverse total shoulder arthroplasty or other revision procedures among partial repair, complete repair and superior capsular reconstruction for massive irreparable rotator cuff tears. It is crucial to understand the long-term outcomes of different surgical techniques for massive rotator cuff tears, particularly regarding failure rates and progression to further procedures.

A composite PET-matrix patch enhances tendon regeneration and tendon-to-bone integration for bridging repair of the chronic massive rotator cuff tears in a rabbit model

In recent years, bridging repair has emerged as an effective approach for the treatment of massive rotator cuff tears (MRCTs). The objective of this study was to develop a composite patch that combines superior mechanical strength and biocompatibility and evaluate its potential for enhancing the outcomes of bridging repair for MRCTs. The composite patch, referred to as the PET-matrix patch (PM), was fabricated by immersing a plain-woven PET patch in decellularized matrix gel and utilizing the freeze-drying technique. The results demonstrated that the PM has reliable mechanical properties, with a maximum failure load of up to 480 N. The decellularized matrix sponge (DMS), present on the surface of the PM, displayed a loose and porous structure, with an average pore size of 62.51 μm and a porosity of 95.43%. In vitro experiments showed significant elongation of tenocytes on the DMS, with cells spanning across multiple pores and extending multiple protrusions as observed on SEM images. In contrast, tenocytes on the PET patch appeared smaller in size and lacked significant elongation. Additionally, the DMS facilitated the proliferation, migration and differentiation of tenocytes. In a rabbit model of chronic MRCTs, the PM group showed superior outcomes compared to the PET group at 4, 8 and 12 weeks after bridging repair. The PM group displayed significantly higher tendon maturing score, larger collagen diameter in the regenerated tendon and improved tendon-to-bone healing scores compared to the PET group (P < 0.05). Moreover, the maximum failure load of the tendon-bone complex in the PM group was significantly higher than that in the PET group (P < 0.05). In summary, the PM possesses reliable mechanical properties and excellent cytocompatibility, which can significantly improve the outcomes of bridging repair for chronic MRCTs in rabbits. Therefore, it holds great potential for clinical applications.

Subacromial Balloon Placement Demonstrates No Advantage Over Debridement in the Treatment of Massive Irreparable Rotator Cuff Tears: A Dual-Armed Systematic Review and Meta-analysis of Over 1000 Patients

BACKGROUND

In recent years, the placement of a subacromial balloon (SAB) spacer has emerged as a treatment option for massive irreparable rotator cuff tears (MIRCTs); however, there is significant controversy regarding its utility in comparison with other surgical interventions.

PURPOSE

To compare outcomes after SAB spacer placement versus arthroscopic debridement for MIRCTs.

STUDY DESIGN

Dual-armed systematic review and meta-analysis (level IV evidence).

METHODS

A literature search of PubMed (MEDLINE), Scopus, and CINAHL Complete databases for articles published before May 7, 2022, was conducted to identify patients with MIRCTs undergoing the 2 procedures. For the SAB arm, 14 of 449 studies were considered eligible for inclusion, while 14 of 272 studies were considered eligible for inclusion in the debridement arm.

RESULTS

In total, 528 patients were eligible for inclusion in the SAB arm and 479 patients in the debridement arm, and 69.9% of patients undergoing SAB placement also underwent concomitant debridement. Decreases in the visual analog scale (VAS) pain score and increases in the Constant score were found to be significantly larger after debridement (-0.7 points [P < .001] and +5.5 points [P < .001], respectively), although the Patient Acceptable Symptom State for the VAS was not achieved after either procedure. Both SAB placement and debridement significantly improved range of motion in forward flexion/forward elevation, internal and external rotation, and abduction (P < .001). Rates of general complication were higher after debridement versus SAB placement (5.2% ± 5.6% vs 3.5% ± 6.3%, respectively; P < .001); however, there were no significant differences between SAB placement and debridement in rates of persistent symptoms requiring a reintervention (3.3% ± 6.2% vs 3.8% ± 7.3%, respectively; P = .252) or reoperation rates (5.1% ± 7.6% vs 4.8% ± 8.4%, respectively; P = .552). The mean time to conversion to reverse total shoulder arthroplasty was 11.0 versus 25.4 months, respectively, for the SAB versus debridement arm.

CONCLUSION

While SAB placement was associated with acceptable postoperative outcomes in the treatment of MIRCTs, there was no clear benefit over debridement alone. Shorter operative times coupled with better postoperative outcomes and longer times to conversion to reverse total shoulder arthroplasty rendered debridement a more attractive option. While there may be a role for SAB placement in poor surgical candidates, there is burgeoning evidence to support debridement alone without SAB placement for the treatment of MIRCTs.

Outcomes of Isolated Biceps Tenodesis/Tenotomy or Partial Rotator Cuff Repair Associated with Biceps Tenodesis/Tenotomy for Massive Irreparable Tears: A Systematic Review

Irreparable large to massive rotator cuff tears (MIRCTs) are a prevalent cause of shoulder pain and dysfunction, and nonoperative treatment may not always be effective. Various surgical options exist, with isolated biceps tenotomy/tenodesis (BT) or arthroscopic partial repair with associated biceps tenotomy/tenodesis (PCR-BT) being the most common. The aim of this study was to systematically review the available data on the clinical and functional outcomes of BT and PCR-BT in patients with MIRCTs.

METHODS

MEDLINE, Embase, and CENTRAL databases were searched for studies on the treatment of MIRCT. We included studies with BT or PCR-BT with a minimum follow-up of 24 months. The MINORS (Methodological Index for Nonrandomized Studies) score was used to assess study quality. Outcomes included were the visual analog scale for pain, functional scores such as Constant-Murley and American Shoulder and Elbow Surgeons, range of motion, radiological measurements, and complications.

RESULTS

A total of 1101 patients (506 had a BT and 595 had a PCR-BT) from 22 studies were included (cases series = 13, case-control = 7, randomized control trial = 1, prospective cohort study = 1). The mean MINORS score was 13.2 ± 3.2. The mean age and follow-up were 67 ± 6.8 years and 4.58 ± 1.1 years (range, 2, 12), respectively. The VAS improvement showed at the last follow-up for PCR-BT (range, 1.97, 5.8) and BT (range, 4, 6.1). CMS was improved at the final follow-up for PCR-BT (range, 13, 47.6) and BT (range, 10.8, 28). Regarding the ASES, it has demonstrated significant improvements for PCR-BT (range, 31.81, 44.8) and BT (range, 30,45.8). For forward flexion, PCR-BT showed improvement (range, -14°, 59.4°), as well as the BT group (range, 2°, 27.9°).

CONCLUSIONS

This systematic review demonstrated that both BT and PCR-BT improve functional outcomes and reduce pain at midterm follow-up for MIRCT. Since we know that a failed cuff repair would worsen the shoulder, it might be beneficial in terms of the risk-benefit ratio to not repair in certain patients with MIRCT.

Management of Irreparable Posterosuperior Rotator Cuff Tears-A Current Concepts Review and Proposed Treatment Algorithm by the AGA Shoulder Committee

Posterosuperior rotator cuff tears range among the most common causes of shoulder complaints. While non-operative treatment is typically reserved for the elderly patient with low functional demands, surgical treatment is considered the gold standard for active patients. More precisely, an anatomic rotator cuff repair (RCR) is considered the most desirable treatment option and should be generally attempted during surgery. If an anatomic RCR is impossible, the adequate choice of treatment for irreparable rotator cuff tears remains a matter of debate among shoulder surgeons. Following a critical review of the contemporary literature, the authors suggest the following evidence- and experience-based treatment recommendation. In the non-functional, osteoarthritic shoulder, treatment strategies in the management of irreparable posterosuperior RCT include debridement-based procedures and reverse total shoulder arthroplasty as the treatment of choice. Joint-preserving procedures aimed at restoring glenohumeral biomechanics and function should be reserved for the non-osteoarthritic shoulder. Prior to these procedures, however, patients should be counseled about deteriorating results over time. Recent innovations such as the superior capsule reconstruction and the implantation of a subacromial spacer show promising short-term results, yet future studies with long-term follow-up are required to derive stronger recommendations.

Early Treatment of Shoulder Pathology Is Necessary but Not Enough Is Being Performed

Delayed treatment of shoulder instability results in bone loss requiring more-complicated surgery, in turn resulting in less-optimal outcomes. Similarly, delayed treatment of repairable rotator cuff tears results in irreparable tears requiring more-complicated surgery and resulting in less-optimal outcomes. Delayed treatment of shoulder pathology is a problem. Solutions include education and research investigation.

Method for the treatment of patients with massive tears of the rotator cuff

Rotator cuff tears are the most common cause of shoulder pain and dysfunction in older patients. Tear with retraction greater than 5cm or with the involvement of two and more tendons are considered massive. According to the literature, the incidence of massive injuries of the rotator cuff ranges from 10 to 40%. The formation of massive injuries is a long process leading to a pronounced pain syndrome, loss of function and, as a result, to pseudo-paralysis of the affected limb. There is no consensus concerning the treatment of this category of patients. Conservative methods of treatment are applicable for patients with a low activity. Among the surgical methods of treatment, the preference is given to the proximal capsule reconstruction, subacromial balloon arthroplasty, reverse arthroplasty and muscle-tendon transfers. However, today there is no single tactic of surgical treatment of patients with rotator cuff massive tears. We propose a new surgical method for this shoulder joint pathology arthroscopically-associated transposition of the tendon of the latissimus dorsi muscle using an autograft of the long peroneal muscle tendon. As a description of the new method, we present a successful clinical case of the treatment of a patient with chronic massive rotator cuff injury of the right shoulder and secondary upper subluxation of the right humerus head. This method allows to increase the efficiency of treatment of a massive tear of the rotator cuff tendons, to restore the correct biomechanics of the shoulder joint, to reduce the pain and to restore the function of the affected limb.

Nonarthroplasty options for massive, irreparable rotator cuff tears have improvement in range of motion and patient-reported outcomes at short-term follow-up: a systematic review

PURPOSE

To compare various nonarthroplasty treatment options for massive, irreparable rotator cuff tears, including allograft bridging/augmentation, debridement, partial repair, superior capsule reconstruction (SCR), subacromial balloon spacer, and tendon transfer.

METHODS

A comprehensive search was conducted through the PubMed, MEDLINE, and EMBASE databases for all articles pertaining to nonarthroplasty treatment options for irreparable rotator cuff tears. Inclusion criteria included manuscripts published between 2009 and 2020 with at least 1 year follow-up and Level I-IV evidence. Articles were separated into six groups: debridement, arthroscopic and open repair, allograft bridging/augmentation, SCR, subacromial balloon spacer, and tendon transfer. Data points included range of motion (external rotation, abduction, forward flexion, and internal rotation), visual analog scale (VAS) pain score, American Shoulder and Elbow Surgeons (ASES) score, Constant score, rate of revision surgery, and rate of conversion to arthroplasty.

RESULTS

A total of 83 studies and 3363 patients were included. All treatment options had statistically significant improvements in postoperative range of motion and patient-reported outcomes. Debridement had statistically significantly greater postoperative abduction and forward flexion range of motion, as well as better VAS pain scores, compared to the other treatment options. The SCR subgroup had the greatest improvement in ASES scores postoperatively. The overall revision rate was 7.2% among all surgical options, with the allograft bridging/augmentation group having the lowest rate of revision at 0-8.3%. The overall rate of conversion to arthroplasty was 7.2%, with debridement having the greatest rate of conversion at 15.4%.

CONCLUSION

All six nonarthroplasty treatment options for irreparable rotator cuff tears resulted in statistically significant improvements in range of motion and patient-reported outcomes at 1 year follow-up or more, with low rates of revision and conversion to arthroplasty. Debridement had statistically significantly greater postoperative abduction and forward flexion range of motion, as well as better VAS pain scores, compared to the other treatment options. However, these conclusions should be interpreted with caution due to the heterogeneous nature of the data, lack of prospective randomized control trials, and short-term follow-up. The findings of this study highlight the complexity of irreparable, massive rotator cuff tears, and the need for an individualized approach when treating these patients.

Biceps-incorporating rotator cuff repair with footprint medialization in large-to-massive rotator cuff tears

PURPOSE

In large-to-massive rotator cuff tears (MRCTs), incorporating the long head of the biceps tendon (LHBT) with arthroscopic partial rotator cuff and margin convergence can improve clinical outcomes and preserve the acromio-humeral interval (AHI) during mid-term follow-up. The purpose of this study was to evaluate mid-term clinical and radiological outcomes of arthroscopic biceps-incorporating rotator cuff repair with partial release of the LHBT and footprint medialization through the Neviaser portal in MRCTs.

METHODS

This study enrolled 107 patients (38 males and 69 females, mean age: 64.9 ± 8.6 years) with MRCTs. A novel arthroscopic biceps-incorporating repair was performed by footprint medialization, with a partially released biceps tendon covering central defects. Clinical outcomes such as pain VAS, KSS, ASES, UCLA, SST and CS scores and ROM were evaluated at a mean follow-up time of 35 months (range 12-132 months). Serial radiographs with a mean postoperative MRI follow-up duration of 33 months were used to evaluate AHI, tendon integrity, fatty infiltration (FI) and muscle hypotrophy.

RESULTS

Postoperative pain VAS, KSS, ASES, UCLA, SST, and CS scores and ROM (except external rotation) were improved significantly. AHI also improved significantly from 8.6 to 9.3 mm. According to Sugaya's classification, type I, II, III, IV, or V healing status was found in 30 (28.0%), 29 (27.1%), 26 (24.3%), 14 (13.1%), and 8 (7.5%) patients, respectively. The retear rate was 22 (20.6%).

CONCLUSIONS

Novel biceps-incorporating cuff repair with footprint medialization yielded satisfactory outcomes in MRCT patients at the 3-year follow-up. A partially released, repaired biceps tendon provided superior stability with preserved AHI similar to that of anterior cable reconstruction.

Application of virtual touch tissue imaging quantification in diagnosis of supraspinatus tendon injury

OBJECTIVE

To explore the value of virtual touch imaging and quantification (VTIQ) shear wave elastography (SWE) in diagnosis of supraspinatus tendon tear.

METHODS

Eighty patients with unilateral supraspinatus tendon tear underwent shoulder arthroscopy were prospective studied. Tendinopathy, partial-thickness tear or full-thickness tear of supraspinatus tendon were diagnosed according 2D ultrasound examination. Sensitivity, specificity and accuracy of ultrasonic diagnosis of supraspinatus tendon tear were calculated by arthroscopy as the gold standard. VTIQ was applied to measure the shear-wave velocity (SWV) of both normal and affected supraspinatus tendon. The differences of SWV in three types of supraspinatus tendon tear and receiver operating characteristic (ROC) curves were analyzed.

RESULTS

Among 80 patients, there were 20 tendinopathy, 31 partial tears and 29 full-thickness tears diagnosed by shoulder arthroscopy. Sensitivity, specificity and accuracy of 2D ultrasound in diagnosis of tendinopathy, partial tear and full-thickness tear groups were 78%, 90%and 83%; 71%, 86%and 73%; 86%, 88%and 88%, respectively. SWV of 80 supraspinatus tendon tears was 4.59±1.00 m/s, which was lower than that of normal supraspinatus tendon (4.59±1.00 m/s vs. 6.68±1.05 m/s, P < 0.01). SWV of supraspinatus tendon in tendinopathy, partial tear and full-thickness tear groups respectively were 5.66±0.97, 4.66±1.00, and 3.78±0.55 m/s, all lower than that of the contralateral normal supraspinatus tendon (all P < 0.05). In addition, the analysis of variance and pairwise comparison showed that SWV of supraspinatus tendon among three different degree of injury was statistically significant (all P < 0.001). The cutoff thresholds of SWV was 4.83 m/s to identify tendinopathy tear from partial tear and was 4.08 m/s to identify full-thickness tear from partial-thickness tear.

CONCLUSION

VTIQ SWE with SWV might identify degree of supraspinatus tendon tear and improve the value of ultrasonography, which should be further evaluated in large multicenter studies.
