コンタクトスポーツ選手の鏡視下 Bankart 修復術後のスポーツ復帰

抄録

The purpose of this study was to evaluate clinical results of arthroscopic Bankart repair for contact sports athletes with recurrent anterior shoulder instability. We retrospectively studied 19 patients (21 shoulders) who were treated with arthroscopic Bankart repair and were followed-up for more than 1 year postoperatively. The average age at the time of surgery was 19.8years old (range, 16 to 34), the average follow-up was 38.5 months (range, 12 to 69). Indication of arthroscopic Bankart repair was that we could repair AIGHL-Labrum complex and glenoid bone loss was 25% or less. We evaluated the clinical outcome by JSS shoulder instability score, level of return to sports activities, the recurrence rate of dislocation, satisfaction level and complications. The average postoperative JSS score was 79.8. Although all patients returned to contact sports, 39% could not return to preinjury sports activity levels. 3 patients had recurrence of dislocation, and 7 reported fear of recurrence when tackling. Satisfaction was 14 satisfied, 3 slightly satisfied, 4 slightly unsatisfied. There was one patient with ER limitation, postoperatively. Previously, we had treated contact sports athletes with recurrent anterior shoulder dislocation with the modified Bankart and Bristow procedure. Although the recurrence rate was low, the range of motion was limited in almost half the patients. Although in this study was all patients returned to contact sports activities, the recurrence rate was 14.3% and incomplete return was 39%. We think arthroscopic Bankart repair is not satisfactory for contact sports athletes.
