Progression to Glenohumeral Arthritis after Arthroscopic Posterior Stabilization in a Young and High Demand Population

Video Transcription

Video Summary

In this video, the speaker discusses the limited data available on evaluating the progression to arthritis following arthroscopic anterior stabilization. Previous studies have reported rates between 8 and 22% of the patient population, with older age and recurrent instability events as risk factors. However, there is no available data on progression to arthritis in posterior shoulder instability cases. The study aimed to assess the progression to and risk factors for arthritis in two young patient populations undergoing arthroscopic shoulder stabilization. The study analyzed active-duty service members who underwent the procedure between 2004 and 2016. The incidence of glenohumeral arthritis was assessed, and risk factors were identified using Cox regression analysis. Results showed that older age at index surgery, number of anchors used, and revision surgery were risk factors for anterior progression to arthritis. In the posterior group, no significant risk factors were identified. The study suggests that early surgical intervention may be beneficial for younger patients with anterior shoulder instability. However, the low number of events in the posterior group limited statistical analysis, indicating that larger studies are needed. Overall, the rate of arthritis in young high-demand patients is low for both anterior and posterior shoulder instability groups. The strongest predictor for arthritis in the anterior group is revision surgery.
