In the randomized clinical trial, 196 patients with traumatic unidirectional anterior shoulder instability underwent open (Fig. 1) or arthroscopic (Fig. 2) repair (open, n = 98; arthroscopic, n = 98). Both groups consisted of 80 males and 18 females. The mean age in the open group was 27.8 years; in the arthroscopic group, it was 27.2 years. Expertise-based randomization allowed the participating surgeons to perform their preferred surgical technique for the repairs.

Investigators analyzed baseline characteristics and found no statistically significant differences regarding gender distribution, operative side, hand dominance, age, participation in sports, or WOSI scores between the two groups. On average, arthroscopic procedures were completed in 1 hour and 1 minute, while the open procedures took an average of 1 hour and 17 minutes.
- Both open and arthroscopic approaches for treating traumatic anterior shoulder dislocation have similar functional and quality of life outcomes.
- Using an open, rather than arthroscopic, technique results in a lower rate of recurrence in patients with recurrent shoulder instability.
- The presence of a Hill Sachs lesion and younger age are likely associated with recurrent instability.
