Arthroscopic Repair In Treatment Of Medium And Small Rotator Cuff Tear Under Post Type

Objective To study the methods and evaluate the recently clinical outcomes of arthroscopic repair for medium and small rotator cuff tear under Post type. Methods A retrospective analysis of preoperative, intraoperative and postoperative rehabilitation programs of 76 patients with rotator cuff tears, who are treated consecutively between 2013 to 2014 at our hospital, was carried out to evaluate the outcome of arthroscopic techniques. The adapted cases were selected through the inclusion and exclusion criteria, and intraoperative details were concluded. The range of motion, the visual analog pain scale scores(VAS), the rating scale of the University of California at Los Angels(UCLA), and the rating of Constant-Murley were determined as the evolution criteria. Result 31 cases met the acceptance standards. These cases include 11 cases of male and 20 cases of female with average age of 54.2(43-67). The follow-up visit period lasted from 12 to 30 months, on average of 15.7 months. Pre-operation: VAS score was 8.4; the total active motion of shoulder joint showed 95.2°on average in anteflexion upward, 40.5°in body side extorsion, 32.7°in body front adduction and 37.1°in intorsion; the total passive motion of shoulder joint showed 117.2°on average in anteflexion upward, 46.3°in body side extorsion, 41.5°in body front adduction and 42.4°in intorsion. UCLA score was 12.3 and Constant-Murley score was 43.6. Intraoperative treatment: 19 cases of removal of synovial membrane of glenohumeral joint; 5 cases of joint capsule release, among which 4 cases were involved with upper joint capsule and 1 case with lower capsule; 2 cases of pure removal of longhead of bicipital tendon, 3 cases of fixing longhead of bicipital tendon and 2 cases of cutting down longhead of bicipital tendon; 31 cases of clean subacromial bursa; 26 cases of acromion shaping; 14 cases of coracoacromial arch; 6 cases of coracoids shaping and 31 cases of rotator cuff reparing. Post-operation: VAS score was 3.7; the total active motion of shoulder joint showed 157.3°on average in anteflexion upward, 73.3°in body side extorsion, 54.4°in body front adduction and 57.3°in intorsion; the total passive motion of shoulder joint showed 168.3°on average in anteflexion upward, 78.8°in body side extorsion, 58.7°in body front adduction and 61.5°in intorsion. UCLA score was 28.5 and Constant-Murley score was 85.9. All indicators before and after operation P<0.05 have statistical significance. Conclusion Different operation methods for the arthroscopic treatment of rotator cuff injury need to be adopted to the pathological change under the scope, the treatment effect of small and medium size rotator cuff injury under Post type is satisfactory.
