Treatment of rotator cuff tear in global stiff shoulder by arthroscopic 360° capsular release with concomitant rotator cuff repair / 中国骨伤

ABSTRACT

OBJECTIVE@#To evaluate the clinical effect of arthroscopic 360° capsular release with concomitant rotator cuff repair for patients with rotator cuff tears in global stiff shoulder.@*METHODS@#From December 2016 to December 2018, 247 patients full-thickness rotator cuff tear were treated with arthroscopic rotator cuff repair. Among them, 42 patients (17%) with global limitation of shoulder movement were treated with arthroscopic 360° capsular release operation at the same time of rotator cuff repair. The function of shoulder was evaluated by Constant-Murley score and visual analogue scales (VAS), flexion, abduction and external rotation on body side before and after operation. Sugaya classification was used to evaluatethe healing of rotator cuff. The number of shoulder dislocations during follow-up was recorded.@*RESULTS@#Thirty nine of the 42 patients were followed up for 12 to 36 (22±6) months. The patients were 43 to 73 (57±7) years old at the time of operation. The Constant- Murley score increased from (43.6±6.3) before operation to (87.5±2.8) at final follow-up (<0.001). VAS score decreased from (7.2±1.5) before operation to (1.0±0.9) at final follow-up (<0.001). The flexion of shoulder increased from (46±14)° before operation to (148±11)° after operation (<0.001), the abduction from (36±6)° before operation to (121±10)° after operation (<0.001), and the external rotation on body side from (5±10)° before operation to (42±8)° after operation(<0.001). One year after the operation, MRI showed thatⅠ-Ⅲ of Sugaya classification was clinical healing, 38 cases in total.@*CONCLUSION@#Arthroscopic 360° capsular release with concomitant rotator cuff repair was used to treat rotator cuff tear in global stiff shoulder. Themain observation indexes were improved after operation, and the clinical effect was definite.
