Purpose The aim of the present retrospective study is to describe the results obtained at 2-year follow-up by using a porcine dermis-derived collagen membrane implanted as augmentation to treat large rotator cuff tears. Methods Thirty-five patients in total were included according to the following criteria: large or massive rotator cuff tear, confirmed during surgery, measuring between 3 and 5 cm in width and stage 1 to 2 fatty infiltration documented at magnetic resonance imaging (MRI). Patients underwent arthroscopic repair of the cuff augmented by the implantation of a porcine dermal collagen membrane. Patients were evaluated up to 24 months after surgery by the Constant score and MRI imaging to assess functional outcomes and re-tear rate. The results obtained were compared to those of a matched cohort of 35 patients operated by arthroscopic repair alone by the same surgical team. Results The application of the porcine membrane proved to be safe without scaffold-related adverse events documented. A statistically significant difference in the Constant score in favor of the treatment group was documented at the final evaluation (p = 0.036). Furthermore, a subgroup analysis revealed that patients treated by augmentation and presenting re-tear at MRI showed a significantly higher functional outcome compared with control patients with MRI evidence of re-tear (p = 0.0136). Conclusion Arthroscopic repair augmented by porcine dermal xenograft for the treatment of chronic and retracted rotator cuff tears with low-grade fatty degeneration proved to be safe and also effective, with higher functional score compared with the arthroscopic repair alone. Level of Evidence This is a Level III, retrospective cohort study.

Purpose: the aim of this study was to compare clinical outcomes of contracted immobile massive rotator cuff tears mobilised through an arthroscopic interval slide technique versus massive mobile cuff tears directly repaired without any mobilisation. Methods: twenty-five patients who underwent arthroscopic repair for massive rotator cuff tears with a minimum of 18 months follow-up were included. The patients were retrospectively divided into two groups. In group 1, a single or double interval slide was performed to achieve adequate tendon mobilisation. In group 2 (control group), massive rotator cuff tears were arthroscopically repaired without any additional release. Patients were evaluated with validated outcomes scores: subjective and objective Constant score, a Visual Analogue Scale (VAS) for pain, and single Assessment Numeric Evaluation (SANE). Results: the two groups were comparable in terms of age, gender and involvement of the dominant arm. The mean follow-up duration was 31 months in group 1 and 28 months in group 2 (p = 0.4). The two groups showed no significant differences in SANE and VAS results (group 1: SANE 77%, VAS 1.3; group 2: SANE 88%, VAS 1.6), or in total Constant score (group1: 66.5 ± 11; group 2: 75 ± 14; p = 0.1) and subjective Constant score (Group 1: 31 ± 5; group 2: 30.8 ± 7; p = 0.9). A significant difference was found for the objective Constant score, which was higher in the control group (group 1: 35.5 ± 7; group 2: 44 ± 8; p = 0.009). Conclusions: Subjective clinical outcomes of arthroscopic repair with or without interval slides did not differ and were satisfactory. Objectively, immobile cuff tears showed inferior results.The use of interval slides might be considered a first step or an alternative to more invasive procedures for low demanding patients. Level of evidence: Level III, retrospective comparative 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.

Background The surgical management of massive rotator cuff tears remains a challenge. It is suggested that, even in a massive tear that appears irreparable, attempting to repair it as much as possible can be helpful in improving functional outcomes. However the results can be short term and variable. The purpose of our study was to determine if human tissue allograft bridged repair of massive irreparable rotator cuff tears to achieve a complete repair produces similar outcomes compared to partial repair alone. Methods We prospectively reviewed outcome scores in 13 patients who underwent partial repair alone for massive irreparable rotator cuff tears and compared them to 13 patients who had partial repairs bridged with allograft. Oxford and Constant scores were compared pre-operatively and at a minimum follow-up of 2 years (range 2 years to 5 years). Results The mean improvement in the Constant score at final follow-up compared to pre-operative scores was 27.7 points in the partial repair group and 42.8 points in the allograft group ( p < 0.01). The Oxford Shoulder Score improved mean of 19.3 points in the partial repair group and 29 points in the allograft group ( p < 0.02) at 2 years. Conclusions Human tissue matrix allograft provides a better outcome for open bridging of irreparable rotator cuff tears than partial repair alone.

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.

Infraspinatus Tendon

Background: In shoulders with irreparable massive rotator cuff tears (RCTs) with high-grade fatty degeneration (Goutallier stage 3 or 4) of the supraspinatus tendon and low-grade fatty degeneration (Goutallier stage 1 or 2) of the infraspinatus tendon (ISP), arthroscopic patch grafting (PG) has been reported as superior to partial repair (PR) regarding the ISP retear rate at short-term to midterm follow-up. However, the longer term outcomes are unclear. Purpose: To compare clinical and structural outcomes in the PG and PR groups at a minimum of 7 years postoperatively. Study Design: Cohort study; Level of evidence, 3. Methods: We evaluated 24 patients in the PG group and 24 patients in the PR group. We primarily used the Constant score for clinical outcomes and performed magnetic resonance imaging for structural outcomes in the PG and PR groups. The risk factors for a retear of the ISP were identified by univariate and multivariate (forward stepwise selection method) logistic regression analyses. We primarily compared values at midterm follow-up (<4 years) with values at the final follow-up (minimum 7 years) for each patient. Results: The mean midterm and final follow-up times for the PG group were 41.0 and 95.1 months, respectively, compared with 35.7 and 99.3 months, respectively, for the PR group. We found significant differences for the midterm and final follow-up Constant total scores in the PG and PR groups (midterm follow-up: 79.1 vs 69.9, respectively [ P = .001]; final follow-up: 76.0 vs 65.3, respectively [ P = .006]) and in the Constant strength scores (midterm follow-up: 14.6 vs 8.5, respectively [ P < .001]; final follow-up: 13.1 vs 8.3, respectively [ P = .001]). Treatment group (PR) was a significant predictor of an ISP retear in the logistic regression analysis (odds ratio, 3.545; P = .043). Conclusion: Patients with low-grade massive RCTs treated with PG or PR improved significantly in terms of clinical outcomes at the midterm and final follow-up time points. However, Constant scores were significantly better in the PG group at the final follow-up.
