Asymptomatic acromioclavicular joint XXXX in arthroscopic rotator cuff tendon repair: a prospective randomized comparison study.

@entity1 @entity625 @entity158
HYPOTHESIS: Arthroscopic acromioclavicular joint (ACJ) resection for asymptomatic @entity625 combined with rotator cuff repair leads to more @entity158 relief and decrease reoperation rate when inferiorly directed osteophytes present at the undersurface of ACJ. MATERIALS AND METHODS: Between January 2006 and May 2008, a total of 83 @entity1 (83 shoulders), 40 males and 43 females, who were planned to have arthroscopic repair of a tear measuring 1-3  cm in the anterior-posterior dimension with advanced @entity625 with inferiorly directed osteophytes at the undersurface of the ACJ on MRI were entered into this study. @entity1 were randomized into two groups. Group 1 included 31 @entity1 , who underwent arthroscopic distal clavicle resection combined with rotator cuff repair. Group 2 included 52 @entity1 , who underwent isolated rotator cuff repair. @entity1 were evaluated preoperatively and postoperatively using the University of California Los Angeles (UCLA) score and the American Shoulder and Elbow Surgeons (ASES) score. @entity158 , tenderness on ACJ, and cross body adduction test were compared between groups. RESULTS: The mean follow-up was 31.7  months (range 34-38). The UCLA scores and ASES scores were lower in group 1 at week 6 (p  <  .05), and week 12 (p  <  .05), but higher at the last follow-up at 2  years (p  <  .05) postoperatively. VAS score was higher in group 1 at week 6 (p  <  .05), and at week 12 (p  <  .05), but lower in group 2 at the last follow-up (p  <  .05). Only in group 2, two (3.8%) cases developed @entity158 during follow-up and one (1.9%) case underwent reoperation for additional ACJ resection. CONCLUSIONS: This study shows that distal clavicle resection combined with rotator cuff repair for asymptomatic @entity625 with inferiorly directed osteophytes lower functional scores due to @entity158 in early postoperative periods, but better functional outcomes with @entity158 relief and no reoperation rate were observed after 2  years.
