Abstract Background: It is not yet clear whether muscle atrophy and fat degeneration have improved after successful arthroscopic rotator cuff repair. Therefore, in this study, the quantitative MRI measurement was performed to evaluate the changes of muscle atrophy and fat degeneration before and after surgery more accurately and to analyze the correlation between changes in muscle atrophy and fat degeneration and clinical outcome.Materials and Methods: From March 2013 to March 2017, 40 patients who had no retear up to 1 year after rotator cuff repair were taken before surgery, 3 days after surgery, and 1 year after surgery. Supraspinatus muscle atrophy and fat infiltration were measured quantitatively in Conventional Y view and Supraspinatus origin view. The measurement items were muscle area , occupation ratio, degree of fat degeneration (%) and area of fat degeneration (㎣). Postoperative clinical results were measured by ASES score and Constant score at 1 year. Correlation between values and scores was analyzed. Results: Inter-measurement reliability was high (ICC = 0.933, Cronbach-α = 0.963). There was no significant change in muscle atrophy in Conventional Y-view at 1 year after surgery (Occupation ratio:P = 0.2770; Muscle area(㎣) P = 0.3049) and muscle atrophy in Supraspinatus origin view(Muscle area(㎣) P = 0.5953). Fatty Infiltration (%) and fat area (㎣) measured with conventional method on Y-view and showed significant difference (P = 0.0001). Fatty Infiltration (%) and fat area (㎣) measured with modify method on Y-view and SOV-view showed no significant difference (all P >0.05). Postoperative constant score and ASES showed significant improvement compared to preoperative (P = 0.0001), but there was no correlation between fat infiltration and muscle atrophy. (P = 0.653) Conclusion: Clinical outcome (ASES, Constant score) was significantly improved after rotator cuff repair surgery. Clinical outcome (ASES, Constant score) does not have correlation with FI & MA. Muscle Atrophy does not have change 1-year after surgery. Fatty Infiltration was improved in Y-view measured by conventional method. Keywords: Fatty infiltration, Muscle atrophy, Arthroscopic rotator cuff repair, Supraspinatus origin view, Y-view

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 Purpose: Aim of the present study was to prospectively evaluate the elbow flexion and supination strengths, and the functional outcomes of patients after arthroscopic rotator cuff repair combined with simultaneous biceps tenodesis.Methods: Nineteen patients who underwent arthroscopic rotator cuff repair and biceps tenodesis with at least 24 months follow-up were included. Patients were evaluated using a visual analogue scale (VAS) for bicipital groove pain, American Shoulder and Elbow Surgeons (ASES), and constant scores(CS), biceps apex distance (BAD), elbow flexion and supination strengths.Results: VAS for biceps groove measurement averages of postoperative 6th, 12th and 24th month were lower in comparison to pre-operative data and were considered to be statistically significant (p<0.05). Constant score, an average of all post-operative measurements and scores were found higher than pre-operative values and was considered to be statistically significant (p<0,01). There was a significant difference in the comparison of operated and contralateral forearm supination and elbow flexion muscle strength measurements at postoperative 3rd and 6th-month follow-up (p<0.01).Conclusion: Arthroscopic biceps tenodesis into the anchors of lateral row combined rotator cuff repair provides an increase in strength of elbow flexion and forearm supination, while decreases pain. Level of Evidence: Level IV
