Arthroscopic Bankart shoulder stabilization in athletes: return to sports and functional outcomes

Purpose

The aim of this study was to evaluate return to sports after arthroscopic Bankart stabilization.

Methods

This is a retrospective study including all athletes aged <50 years who underwent arthroscopic stabilization in 2010 and 2011 (m, 36; f, 10; mean age 28.9 ± 8.1 years; follow-up 24.4 ± 7.7 months). Sixteen patients were practicing competitive sports and 30 recreational sports. Level and delay of return to sports, sports classification according to Allain, Western Ontario Shoulder Instability Index (WOSI) score, patient satisfaction, apprehension level and avoidance behaviour were noted.

Results

95.7 % returned to the same level after an average of 9.8 ± 5.4 months. Sports level was unchanged or better in 82.6 %, lower in 8.7, and 4.5 % changed sport because of their shoulder. Patients with more than 10 dislocations returned to sports and to their preoperative level later than patients with <10. Male athletes returned to preoperative sports levels faster than female athletes (p < 0.001). The WOSI score and also its item “sports” were worse in those who had not returned (p = 0.0002 and 0.006, respectively). Satisfaction correlated with the WOSI score (p = 0.0004) while 93.3 % were satisfied/very satisfied. The decrease in the apprehension level was significant (p < 0.00001). 36.9 % still experienced avoidance behaviour.

Conclusions

Most athletes resumed their main sport often at the same level, but the threshold of 10 dislocations should be considered a risk factor for longer return to sports at any level. The WOSI score is a valuable outcome score after Bankart stabilization. Postoperative avoidance should be distinguished from apprehension.
