Anterior shoulder stabilization in collision athletes: arthroscopic versus open Bankart repair.

BACKGROUND

Collision athletes are reported to be at high risk for redislocation after anterior stabilization of shoulder instability. Some authors have suggested that arthroscopic stabilization produces results similar to those of open stabilization.

PURPOSE: To evaluate the results of anterior shoulder stabilization in collision athletes and to compare the clinical results between the arthroscopic and open methods.

HYPOTHESIS: Open stabilization might produce better results than does arthroscopic stabilization in collision athletes.

STUDY

DESIGN

Cohort study; Level of evidence, 4.

METHODS

Forty-eight shoulders of 46 collision athletes were enrolled for this study. The mean age of the patients at the time of surgery was 20 years, and the mean follow-up period was 72 months (range, 30-136 months). Sixteen shoulders underwent arthroscopic stabilization; 32 shoulders had open repairs.

RESULTS

Visual analog scale, Rowe, and Constant scores improved after surgery, but no statistically significant difference was found between the arthroscopic and open repair groups. Thirty-seven athletes (83%) returned to near-preinjury sports activity levels (>/= 90% recovery) after operation. Two patients (4%) had subluxation and 6 (12.5%) had redislocation after surgery. The number of shoulders with postoperative subluxation or dislocation was 4 (25%) in the arthroscopic group and 4 (12.5%) in the open group (P = .041). Revision surgery was performed on 5 shoulders (10.4%).

CONCLUSIONS

There were 8 (16.5%) instances of postoperative instability among the collision athletes studied. The arthroscopic group yielded a higher failure rate than did the open group. The authors believe open stabilization to be a more reliable method for anterior shoulder instability in collision athletes.
