Outcomes after Arthroscopic Repair of Anterior Shoulder Instability after Metal Anchor to Biodegradable Anchor Fixation

We reviewed 26 patients with anterior shoulder instability treated by arthroscopicBankart repair from October, 2006, to March, 2007, 15 patients with metal anchors and 11 patients withbiodegradable anchors. The average age was 27.4 years old (range: 17~55) and mean follow-up was 14months (range: 12~17 months). Functional outcome was evaluated using the Korean Shoulder Score forInstability (KSSI), Rowe’s Bankart Grading scale (RBGS), ASES score, and UCLA scores.
