Arthroscopic subscapularis augmentation restored shoulder joint stability in athletes
Recently published results showed athletes with chronic anterior shoulder instability treated with arthroscopic subscapularis augmentation experienced restoration of joint stability.
Researchers used the VAS scale for pain, Rowe and American Shoulder and Elbow Surgeons (ASES) scores to assess outcomes of 110 athletes with a history of traumatic recurrent shoulder dislocations, glenoid bone loss ranging from 5% to 25%, anterior capsular deficiency and Hill-Sachs lesion treated with arthroscopic subscapularis augmentation. Researchers measured loss of shoulder external rotation with the arm at the side or 90° in abduction.
Researchers observed a Hill-Sachs lesion in 98 patients, and 57 patients had a capsular deficiency. Results showed traumatic redislocation in 2.7% of patients. According to results, VAS scores decreased from a mean of 3.5 to 0.5 at final follow-up. Researchers also noted an increase in the Rowe score from 57.4 to 95.3 and an increase in the ASES score from 66.5 to 96.5 at final follow-up. Results showed a mean deficit of external rotation of approximately 8° with the arm at the side and of approximately 4° with the arm 90° in abduction. – by Casey Tingle
