Background: Some studies reporting clinical outcomes after transosseous-equivalent (TOE) repair have attributed type II rotator cuff failure to excessive bridging suture tension, as it can cause overloading on the medial row. In a previous biomechanical cadaveric study, increasing bridging suture tension over 90 N did not improve the contact area and ultimate failure load of the TOE construct, despite increasing the contact force and contact pressure. Purpose: To compare the clinical outcomes of different bridging suture tensions after TOE rotator cuff repair based on the results of a previous biomechanical study. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: A total of 78 patients who underwent arthroscopic rotator cuff repair for medium- to large-sized tears were prospectively enrolled and randomly divided into 2 groups according to the applied bridging suture tension: optimum tension group (96.3 ± 4.9 N) and maximum tension group (199.0 ± 20.3 N). Bridging suture tension was measured with a customized tensiometer, as used in the previous biomechanical study. The functional outcome was measured at the final follow-up (27.4 ± 5.9 months [range, 24-45 months]) using the visual analog scale for pain, American Shoulder and Elbow Surgeons score, Simple Shoulder Test, and Constant score, and the anatomic outcome was evaluated using magnetic resonance imaging or ultrasonography at least 12 months after surgery. Results: Overall, 64 patients (32 in each group) were analyzed. The functional outcomes improved significantly compared with preoperative values (all P < .05) but did not show significant differences between the 2 groups (all P > .05). Regarding the anatomic outcomes, the maximum tension group (n = 1; 3.1%) had a significantly lower healing failure rate than the optimum tension group (n = 9; 28.1%) ( P = .013). One patient in the maximum tension group had a type II failure. Conclusion: Maximum bridging suture tension in TOE repair for medium- to large-sized rotator cuff tears provided better anatomic healing with less risk of medial rotator cuff failure, which differs from the results of a previous time-zero biomechanical study.

Abstract: Introduction: In the case of rotator cuff tears, the severity of the muscle atrophy and fatty degeneration has an effect on the success of the repair and on the functional outcome after surgery. Aim: The ability of regeneration reduces with ageing; therefore, the study examined the atrophy and the fatty degeneration after rotator cuff repair in patients over 65. Method: Eleven patients over 65 years of age were involved whose surgery was performed at the Department of Orthopaedics of Semmelweis University between 2012 and 2015. Their average age was 71.9 years and the average follow-up period was 39.9 months. Tear sizes were C1 in 3 cases, C2 in 3 cases, C3 in 4 cases, and C4 in 1 case. Each patient had magnetic resonance examination before and after the repair; the muscle atrophy and fatty degeneration were evaluated together with the type of the tear. Visual analogue scale and Constant score were used for the assessment of the pain and the shoulder function. Results: The average Constant score was 75 points. The occupancy ratio – referring to the severity of the atrophy – did not show significant improvement. The change in fatty degeneration and the atrophy were examined in different groups according to the size of the tears. In each group, the results showed progression. Conclusions: After rotator cuff repair in patients over 65, fatty degeneration and muscle atrophy also show progression. No significant relationship was found between the size of the tear and fatty degeneration or between the size of the tear and muscle atrophy. Orv Hetil. 2019; 160(14): 533–539.

Abstract The critical shoulder angle (CSA) was introduced as a radiological parameter associated with a higher incidence of rotator cuff tears. As a logical consequence, correcting the CSA together with rotator cuff repair should prevent re-tear and provide reliable and good clinical results. We present an all-arthroscopic technique resecting the lateral edge of the acromion (lateral acromioplasty) in order to reduce and correct the CSA after preoperative planning. Preliminary results from 20 patients with an average age of 62 years after rotator cuff repair are reported showing good clinical outcome with a Constant score of 88 points and no re-tear after an average follow-up of 16 months. The CSA was reduced from 39.7° to 32.1°. Previous concerns regarding weakening of the deltoid origin were not confirmed and there were no complications linked to lateral acromioplasty.

Background Nontraumatic full-thickness rotator cuff tears are commonly initially treated conservatively. If conservative treatment fails, rotator cuff repair is a viable subsequent option. The objective of the present meta-analysis is to evaluate the shoulder-specific outcomes one year after arthroscopic or mini-open rotator cuff repair of nontraumatic rotator cuff tears. Methods A literature search was conducted in PubMed and EMBASE within the period January 2000 to January 2017. All studies measuring the clinical outcome at 12 months after nontraumatic rotator cuff repair of full-thickness rotator cuff tears were listed. Results We included 16 randomized controlled trials that met our inclusion criteria with a total of 1.221 shoulders. At 12 months after rotator cuff repair, the mean Constant score had increased 29.5 points; the mean American Shoulder and Elbow Score score increased by 38.6 points; mean Simple Shoulder Test score was 5.6 points; mean University of California Los Angeles score improved by 13.0 points; and finally, mean Visual Analogue Scale score decreased by 4.1 points. Conclusions Based on this meta-analysis, significant improvements in the shoulder-specific indices are observed 12 months after nontraumatic arthroscopic or mini-open rotator cuff repair.

Anchor Fixation

Objectives: All-suture anchor use for rotator cuff repair is increasing. Potential benefits of these anchors include less bone loss from anchor hole drilling and decreased injury to the chondral surface with anchor pullout. Minimal evidence exists comparing clinical outcomes of all suture to solid medial row anchor fixation in double row suture bridge rotator cuff repair. The purpose of this study was to compare patient-reported outcomes for rotator cuff tears treated with all-suture medial row anchors to those treated with more traditional solid anchors. The null hypothesis was that there is no difference in outcomes between the all-suture and solid anchor rotator cuff repairs. Methods: Three sports medicine fellowship trained surgeons performed rotator cuff repairs using the double row suture bridge technique with minimum 3 years of follow up. Patients were separated into two groups based on whether or not they received all-suture or solid anchor fixation for the medial row of their repair. All lateral row fixation was performed with solid anchors. Primary outcomes were evaluated with telephone follow-up and included the American Shoulder and Elbow Surgery Score (ASES), Single Assessment Numeric Evaluation (SANE), and Visual Analog Scale (VAS). The Rehabilitation protocol was the same for all subjects in the study. Results: 3 sports medicine fellowship trained orthopaedic surgeons performed 153 rotator cuff repairs. 91 of these subjects had all-suture fixation of the medial row and 62 received solid anchor fixation. Follow up was 3.6 years ± 0.6 for the all-suture group and 3.7 years ± 0.6 in the solid anchor group (p= 0.28). ASES scores were 92 ± 16 in the all-suture group and 90 ± 17 in the solid group (p =0.35). SANE scores were 91 ± 13 in the all-suture and also 91 ± 13 in the solid anchor cohort (p = 0.97). VAS scores were 1.1 ± 2.0 in the all-suture and 0.7± 1.8 in the solid anchor group (p=0.17). There were no significant differences between groups with regards to re-operation rate or anchor configuration. Conclusions: All suture anchors used in medial row fixation for double row suture bridge rotator cuff repairs have similar clinical outcomes to rotator cuff tears treated in similar fashion with solid medial row anchors.

Retear Rate

Background: The impact of diabetes on clinical and structural outcomes after rotator cuff repair remains controversial. Purpose/Hypothesis: The purpose of this study was to compare clinical outcomes and retear rates after rotator cuff repair in patients with and without diabetes. Our hypotheses were that adequate control of diabetes would decrease the retear rate after rotator cuff repair and that patients with diabetes would have worse clinical outcomes. Study Design: Systematic review; Level of evidence, 3. Methods: The PubMed, Embase, and Cochrane Library databases were searched for studies comparing outcomes in patients with and without diabetes after full-thickness rotator cuff repair. Clinical outcome analysis included the Constant score, the American Shoulder and Elbow Surgeons (ASES) score, and the University of California–Los Angeles shoulder rating scale; we compared preoperative, postoperative, and change in functional scores from baseline to final follow-up among the included studies. The pooled relative risk was calculated using a random-effects model for retear rates. Clinical outcomes were also pooled using a random-effects model. Results: Overall, 10 studies were included. Compared with patients without diabetes, patients with diabetes had a worse preoperative ASES score ( P = .009) as well as worse postoperative Constant score (final follow-up range, 9-103 months; P = .0003). However, there was no significant difference in the absolute mean change in clinical outcomes between patients with and without diabetes. Diabetes was associated with a higher retear rate (19.3% in patients without diabetes vs 28.2% in patients with diabetes; P < .0001). The retear rate according to the severity of sustained hyperglycemia in the subgroup analysis was 14.6% in patients without diabetes, versus 22.7% in patients with well-controlled diabetes (<7.0% of preoperative serum HbA1c level; P = .12) and 40.0% in patients with uncontrolled diabetes (HbA1c level ≥7.0%; P < .00001). Conclusion: This meta-analysis suggests that diabetes mellitus is associated with an increased risk of retears after rotator cuff repair, and improved blood glucose control may reduce the risk of retears in patients with diabetes mellitus. Although effective glycemic control was associated with a decreased risk of retears in patients with diabetes, we could not prove causation because of potential bias and confounding in the included studies.

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.

<p class="abstract"><strong>Background:</strong> Rotator cuff tears are a common source of shoulder pain. The incidence of rotator cuff damage increases with age and is most frequently due to degeneration of the tendon rather than injury from sports or trauma. Rotator cuff tear can be treated arthroscopically, arthroscopically assisted (mini-open) or by an open procedure. Because of the technical demands of arthroscopic repair many surgeons consider open repair for the treatment of rotator cuff tears. This study was done to evaluate the functional outcome of shoulder after open rotator cuff repair.</p><p class="abstract"><strong>Methods:</strong> 26 patients with partial and complete rotator cuff tears underwent open rotator cuff repair and acromioplasty. Cases were followed up at 3 months and 6 months intervals and shoulder function was assessed using Constant-Murley scoring system and compared with the preoperative scores and analyzed using SPSS software.<strong></strong></p><p class="abstract"><strong>Results:</strong> Mean preoperative constant score was 33.95±7.545 while the mean constant score at 6 months post-surgery was 79.83±8.51 which was highly significant according to paired t test. The difference between preoperative, 3 months and 6 months constant scores of complete and partial tear patients was found to be statistically significant.</p><p><strong>Conclusions:</strong> There was highly significant increase in Constant-Murley score after 6 months in patients treated by open rotator cuff repair. Open repair still stands as an effective treatment for rotator cuff tears and doing acromioplasty during the procedure adds to better outcome after surgery.</p>

Background: Since the establishment of biological augmentation to improve the treatment of rotator cuff tears, it is imperative to explore newer techniques to reduce the retear rate and improve long-term shoulder function after rotator cuff repair. This study was undertaken to determine the consequences of a gel-type atelocollagen injection during arthroscopic rotator cuff repair on clinical outcomes, and evaluate its effect on structural integrity.Methods: Between January 2014 and June 2015, 121 patients with full thickness rotator cuff tears underwent arthroscopic rotator cuff repair. Of these, 61 patients were subjected to arthroscopic rotator cuff repair in combination with an atelocollagen injection (group I), and 60 patients underwent arthroscopic rotator cuff repair alone (group II). The visual analogue scale (VAS) for pain and the Korean Shoulder Society (KSS) scores were evaluated preoperatively and postoperatively. Magnetic resonance imaging (MRI) was performed at 6 months postoperatively, to assess the integrity of the repair.Results: VAS scores were significantly lower in group I than in group II at 3, 7, and 14 days after surgery. KSS scores showed no significant difference between groups in the 24 months period of follow-up. No significant difference was obtained in the healing rate of the rotator cuff tear at 6 months postoperatively (<i>p</i>=0.529).Conclusions: Although a gel-type atelocollagen injection results in reduced pain in patients at 2 weeks after surgery, our study does not substantiate the administration of atelocollagen during rotator cuff repair to improve the clinical outcomes and healing of the rotator cuff.
