Background: Because high failure rates have frequently been reported after arthroscopic rotator cuff repair (ARCR) of massive rotator cuff tears (mRCTs), we introduced the technique of ARCR with supraspinatus and infraspinatus muscle advancement (MA). However, for cases where the original footprint cannot be completely covered, additional surgery using an approved artificial biomaterial is performed. Purpose: To investigate the postoperative clinical outcomes and failure rate after MA-ARCR, with and without our reinforcement technique. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 74 patients (mean ± SD age, 68.7 ± 7.7 years) diagnosed with mRCT with a minimum postoperative follow-up of 2 years were included in the current study. Of these patients, 47 underwent MA-ARCR with polyglycolic acid (PGA) sheet reinforcement (study group), and 27 patients underwent MA-ARCR alone (control group). PGA reinforcement was performed when full coverage of the footprint could not be achieved by MA alone, but where the latter was possible, reinforcement was not required. Thus, the study group had significantly worse muscle quality than the control group ( P < .05). The pre- and postoperative range of motion (ROM), isometric muscle strength, acromiohumeral interval, and clinical outcomes were evaluated and compared between these 2 groups. Cuff integrity during the last follow-up period was assessed with magnetic resonance imaging, and the failure rate was calculated. In addition, the postoperative foreign body reaction was investigated in the study group. Results: In both groups, significant postoperative improvements were seen in acromiohumeral interval, clinical scores, ROM in anterior flexion, and isometric muscle strength in abduction, external rotation, and internal rotation ( P < .001 for all). The failure rate of the study group was 12.8% (6 patients) and that of the control group was 25.9% (7 patients). No significant differences were noted between the 2 groups on any of the data findings, even regarding the failure rate. Foreign body reactions in the early period were found in 3 patients, although these spontaneously disappeared within 3 months. Conclusion: Patients who underwent PGA patch reinforcement for MA-ARCR when the footprint could not be completely covered had clinical results similar to isolated MA-ARCR when the footprint could be covered. Both procedures resulted in significant improvement in symptoms and function compared with preoperatively.

Retear Rate

Background: Due to the highly organized tissue and avascular nature of the rotator cuff, rotator cuff tears have limited ability to heal after the tendon is reinserted directly on the greater tubercle of the humerus. Consequently, retears are among the most common complications after rotator cuff repair. Augmentation of rotator cuff repairs with patches has been an active area of research in recent years to reduce retear rate. Hypothesis: Graft augmentation with 3D collagen could prevent retears of the repaired tendon and improve tendon-bone healing in moderate to large rotator cuff tears. Study Design: Randomized controlled study; Level of evidence, 2. Methods: A prospective, randomized controlled study was performed in a consecutive series of 112 patients age 50 to 85 years who underwent rotator cuff repair with the suture-bridge technique (58 patients, control group) or the suture-bridge technique augmented with 3-dimensional (3D) collagen (54 patients, study group). All patients were followed for 28.2 months (range, 24-36 months). Visual analog scale score for pain, University of California Los Angeles (UCLA) shoulder score, and Constant score were determined. Magnetic resonance imaging was performed pre- and postoperatively (at a minimum of 24 months) to evaluate the integrity of the rotator cuff and the retear rate of the repaired tendon. Three patients in each group had biopsies at nearly 24 months after surgery with histological assessment and transmission electron microscopy. Results: A total of 104 patients completed the final follow-up. At the 12-month follow-up, the UCLA shoulder score was 28.1 ± 1.9 in the study group, which was significantly better than that in the control group (26.9 ± 2.1, P = .002). The Constant score was also significantly better in the study group (87.1 ± 3.2) than in the control group (84.9 ± 4.2, P = .003). However, at the final follow-up, no significant differences were found in the UCLA shoulder scores (29.4 ± 1.9 in the control group and 30.0 ± 1.6 in the study group, P = .052) or Constant scores (89.9 ± 3.2 in the control group and 90.8 ± 3.5 in the study group, P = .18). In terms of structural integrity, more patients in the study group had a favorable type I retear grade (18/51) than in the control group (10/53) ( P = .06). The postoperative retear rate was 34.0% in the control group and 13.7% in the study group, thus indicating a significantly lower retear rate in the study group ( P = .02). Biopsy specimens of the tendon-bone interface in 6 patients revealed more bone formation and more aligned fibers with larger diameters in the study group than in the control group. No intraoperative or postoperative complications were noted in either group. Conclusion: 3D collagen augmentation could provide effective treatment of moderate to large rotator cuff tears, providing substantial functional improvement, and could reduce the retear rate. This technique could also promote new tendon-bone formation, thus exerting a prominent effect on tendon-bone healing.

Cuff Repair

Background: Clinical outcomes and prognosis of large and massive rotator cuff tears are known to be unpredictable not only in degeneration of the rotator cuff, but also due to a high rate of retear.Methods: Totally, 81 patients who had undergone arthroscopic rotator cuff repair from May 2008 to February 2016 were evaluated in our study. Clinical and functional evaluations were performed with the Constant score and the University of California, Los Angeles (UCLA) score, as well as full physical examination of the shoulder. All patients were confirmed to have magnetic resonance imaging (MRI) of tendon healing at least 1 year postoperatively.Results: The average age at the time of surgery was 65 years (range, 47?78 years). The average duration of postoperative time in which a follow-up MRI was performed was 36.1 months (range, 12?110 months). Large tears were present in 48 cases (59.3%) and massive tears in 33 cases (40.7%). Overall, there were 33 retear cases (40.7%). All the average clinical outcome scores were significantly improved at the last follow-up (<i>p</i><0.001), although repair integrity was not maintained. Compared to type A, types C, and D of the Collin’s classification showed significantly higher retear rates (<i>p</i>=0.036).Conclusions: Arthroscopic rotator cuff repair yields improved clinical outcomes and a relatively high degree of patient satisfaction, despite the repair integrity not being maintained. Involvement of the subscapularis muscle or infraspinatus muscle had no effect on the retear rate.

Chemical Prophylaxis

Objectives: Venous thromboembolic disease (VTED) is a rare complication following arthroscopic rotator cuff repair (RCR). Historical rates of symptomatic VTED after arthroscopic shoulder surgery, DVT and PE, are 0.26%, and 0.01-0.21%, respectively. At present, the American Academy of Orthopaedic Surgeons (AAOS) and American College of Chest Physicians (ACCP) have no prophylaxis guidelines specific to shoulder arthroscopy. Despite this, many surgeons prescribe Aspirin (ASA) for chemical prophylaxis following RCR. The efficacy of ASA as a thromboprophylaxis after shoulder arthroscopy is unknown, but there are risks associated with its’ use. The purpose of this study is to evaluate the effectiveness of chemical prophylaxis (ASA) and mechanical prophylaxis vs. mechanical prophylaxis alone in preventing VTED following RCR. Methods: A total of 914 patients underwent RCR between the months of January 2010 and January 2015. A retrospective case control study was performed. The control group (n=484) consisted of patients treated with perioperative mechanical VTED prophylaxis (compression boots) and early mobilization. The study group (n=430) also utilized perioperative mechanical prophylaxis and early mobilization, and added chemical prophylaxis (ASA 81 mg daily) for four weeks after surgery. The primary outcome was symptomatic VTED (DVT/PE). Chart records were collected and evaluated for six months after surgery. Patient demographics and other surgical complications were also analyzed. Results: A total of 7 VTED events occurred during the study period, 6 DVTs and 1 PE. The total rate of VTED was 0.88%, DVT was 0.77%, and PE was 0.11%. There was no significant different between DVT (p=0.88, 95% CI= -1.36% - 1.65%) or PE (p=0.45, 95% CI = -0.77% - 1.50%) between the control and study groups. The control group (no ASA) recorded an incidence of 0.62% DVT and 0.00% PE. As compared to the study group (ASA), which recorded an incidence of 0.47% DVT and 0.23% PE. The control group had significantly greater number of documented current smokers (8.68% vs 3.72%, p= 0.0003). The study group had a statistically significant higher mean age of subject (59.1 vs 57.7, p=0.0055), as well as more subjects undergoing revision RCR surgery (4.67% vs 1.86%, p= 0.021). Conclusion: Based on our study of 914 patients, ASA does not provide a clinically significant reduction in VTED rates in patients undergoing RCR. We conclude that the use of mechanical prophylaxis and early mobilization is a sufficient method of VTED prophylaxis in this low risk population.

Background: Older patients with shoulder instability have a higher prevalence of rotator cuff tears and anterior capsular lesions. Simultaneous rotator cuff repair and labral repair are commonly performed to improve shoulder stability and function. Purpose: To investigate the clinical outcomes of arthroscopic rotator cuff repair for older patients with shoulder dislocations combined with massive rotator cuff tears and intact labral tissue. Study Design: Case series; Level of evidence, 3. Methods: A cohort consisting of 11 patients older than 50 years with shoulder dislocations and massive rotator cuff tears undergoing arthroscopic rotator cuff repair was identified between December 2015 and January 2018. Rotator cuff repair was performed after Bankart, superior labral anterior-posterior, and humeral avulsion of the glenohumeral ligament lesions were excluded during arthroscopic surgery. Preoperative and 12-month postoperative outcomes including modified University of California Los Angeles (UCLA), American Shoulder and Elbow Surgeons (ASES), Western Ontario Shoulder Instability Index (WOSI), and visual analog scale for pain scores as well as range of motion (ROM) were recorded. Results: The supraspinatus tendon was torn in all patients. Also, 36.4% of the patients had 3 rotator cuff tendons torn. For shoulder function, the preoperative UCLA score (12.1 ± 2.5 [range, 9-16]) and ASES score (35.4 ± 12.7 [range, 24-44]) significantly improved to 29.4 ± 4.3 (range, 24-35; P < .001) and 79.4 ± 16.0 (range, 45-95; P < .001), respectively, at 12 months postoperatively. None of the patients experienced shoulder redislocations at 12 months after surgery. For shoulder stability, the postoperative WOSI score (156.8 ± 121.0 [range, 45-365]) was significantly better than was the preoperative score (713.0 ± 238.6 [range, 395-1090]) ( P < .001). For comparisons between preoperative and postoperative ROM, forward flexion, abduction, and external and internal rotation at the side significantly improved. Conclusion: For patients older than 50 years with shoulder dislocations combined with massive rotator cuff tears and an intact labrum, arthroscopic rotator cuff repair alone achieved satisfactory functional outcomes and ROM without the recurrence of dislocations.

Cuff Repair

Background: Several treatment options are available for stable massive rotator cuff tears, including partial repair with or without tissue augmentation, tendon transfer, superior capsular reconstruction (SCR), and reverse shoulder arthroplasty. Purpose/Hypothesis: The purpose of this study was to compare the outcomes and effectiveness of partial rotator cuff repair with SCR using the long head of the biceps tendon (PRCR-SCRB) and SCR with a tensor fasciae latae autograft (SCRTF) for the treatment of rotator cuff tears with severe fatty degeneration. The hypothesis of this study was that SCRTF would be superior to PRCR-SCRB in functional and anatomic outcomes. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 26 consecutive patients with massive and fatty degenerative rotator cuff tears were treated surgically. Patients were divided into either the PRCR-SCRB group (n = 14) or SCRTF group (n = 12). Functional outcomes were assessed at final follow-up, and the acromiohumeral distance (AHD) was measured. Results: All functional scores significantly improved in both groups at final follow-up. The PRCR-SCRB group showed better overall outcomes in terms of the visual analog scale for pain; American Shoulder and Elbow Surgeons score; and Quick Disabilities of the Arm, Shoulder and Hand, but these differences were not statistically significant. Better outcomes were found for only the AHD for the PRCR-SCRB group without statistical significance ( P = .4). No statistical difference was found in terms of retear rate. Conclusion: PRCR-SCRB had comparable outcomes and improvement in AHD compared with SCRTF without the need for additional graft harvesting.
