Kim SJ, et al. - Researchers probed the outcomes after arthroscopic stabilization for recurrent traumatic shoulder subluxation in subjects having excessive joint laxity but no history of dislocation. They noted satisfactory overall functional outcomes after arthroscopic stabilization of recurrent shoulder subluxation, despite excessive joint laxity. Nonetheless, in patients with excessive joint laxity plus a glenoid bone defect size of more than approximately 15%, arthroscopic Bankart repair could not be reliable.

Methods

• Authors included 23 patients with glenoid bone defects less than 20% who had undergone arthroscopic stabilization of recurrent shoulder subluxation and were available for at least 2 years follow-up.
• They evaluated the outcomes with the subjective shoulder value (SSV), University of California Los Angeles (UCLA) shoulder score, Rowe score, and sports/recreation activity level.

Results

• Findings suggested that the overall functional scores improved significantly (p < 0.001) vs preoperative scores: SSV improved from 49.1 to 90.4; Rowe score improved from 36.7 to 90.2; and UCLA shoulder score improved from 26.3 to 32.5, postoperatively.
• As per the data, the rate of patient satisfaction was 87% (20/23 patients).
• They noted the sports/recreation activity level (return to premorbid activity level; grade I = 100% to grade IV = less than 70%) to be grade I in 7 patients, grade II in 11, grade III in 3, grade IV in 2.
• Results demonstrated the incidence of any glenoid bone defect to be 61% (14/23 patients), and the mean glenoid bone defect size to be 8%.
• Out of these 14 patients, 8 (35%) exhibited 15–20% glenoid bone defects.
• In 2 patients (9%) who had 15–20% glenoid bone defect, instability reoccurred.
