Our purpose was to compare the effectiveness of traditional treatment with immediate arthroscopic stabilization in young patients who have sustained a first traumatic anterior dislocation of the shoulder. Forty skeletally mature patients younger than 30 years of age were randomly allocated to immobilization for 3 weeks followed by rehabilitation (group T) or arthroscopic stabilization (within 4 weeks of injury) followed by an identical immobilization and rehabilitation protocol (group S). A blinded research assistant performed all follow-up evaluations. The dominant arm was involved in 35% of subjects. The injury occurred in a sporting event in 70% of subjects. At 24 months, there was a statistically significant difference in the rate of redislocation (T = 47%, S = 15.9%, p = 0.03). An intention-to-treat analysis comparing disease-specific quality of life using the validated Western Ontario Shoulder Instability (WOSI) index showed statistically significantly better results in the surgically treated group at the 33 months (T = 633.93 versus S = 287.1, p = 0.03) and no significant difference in range of motion. At an average 32 months follow-up, a significant reduction in redislocation and improvement in disease-specific quality of life is afforded by early arthroscopic stabilization in patients less than 30 year of age with a first, traumatic, anterior dislocation of the shoulder.
