Abstract: Objective To observe the clinical effect of arthroscopic repair on V type superior labral anterior posterior lesions. Methods Sixteen patients with V type superior labral anterior posterior lesions admitted to our hospital from March 2008 to December 2010 served as an experimental group and 16 patients with Bankart lesions served as a control group in this study.Their labral lesions were repaired by arthroscopy with absorbable lines.Their pain was scored according to the visual analogue scale(VAS) and their shoulder joint function was assessed according to the American Shoulder and Elbow Surgeons(ASES) Scoring System and the Rowe Shoulder Scoring System,respectively. Results The VAS,ASES and Rowe scores were higher in the two groups after operation than before operation(P<0.05).No dislocation occurred in all patients after operation.No significant difference was found in the outcomes between the two groups after operation(P>0.05). Conclusion Arthroscopic repair with absorbable line can achieve satisfactory clinical outcomes in patients with should joint dislocation due to V type superior labral anterior posterior lesions.
