Even after successful arthroscopic Bankart repair and capsular shift, women, elite athletes and patients with frequent dislocations were at high risk of capsular restretching, according to study results.
Researchers evaluated the functional outcomes of 105 patients who underwent arthroscopic Bankart repair and capsular shift for anterior shoulder instability and computed tomography arthrography (CTA) at 3 months and 1 year postoperatively. Of the 105 patients, 27 patients also had preoperative CTA, which was used to compare preoperative and 3-month postoperative CTA measurements, while all 105 patients were used for all other comparisons.
The separate anterior and posterior capsular volume and cross-sectional area at the 5-o’clock position were measured using 3-D software and subsequently adjusted for each glenoid size. The researchers also evaluated the changes in capsular volume and cross sectional area at the 5-o’clock position over time, the factors related to higher change in anterior capsular volume and their correlation with outcomes.
