Recurrence and return to sport after surgery for shoulder instability: arthroscopic Bankart versus Latarjet procedure

BACKGROUND: Surgeons differ in their preferences concerning the best surgical technique for treating shoulder instability in sportspeople. The purpose was to evaluate the risk of recurrence and the likelihood of return to sport for the 2 principal shoulder stabilization techniques used to treat shoulder instability in sportspeople. METHODS: We screened sportspeople who had undergone shoulder stabilization for inclusion in this cohort study. For eligibility, patients had to have undergone surgery by one of the 2 techniques: Latarjet or arthroscopic Bankart between 2005 and 2011, and aged from 18 to 35 years. We excluded acromioclavicular dislocation, tendinous lesion, global or posterior instability, bone fracture or severe glenoid bone loss, neurological lesion, other surgical technique, and orthopedic treatment. Patients were contacted by telephone between 2009 and 2012 and asked to participate in follow-up after surgery. The primary endpoint was recurrence, evaluated by determining frequency and time to recurrence (or censoring) with Cox models. The secondary endpoint was the return to sport (training and competition). RESULTS: Follow-up telephone interviews were conducted with 120 sportspeople (response rate of 61.5%), one of whom was excluded due to the occurrence of a new contralateral dislocation before returning to sport after surgery (Latarjet n = 80, Bankart n = 39). The risk of recurrence was significantly higher (P < .001) for Bankart (n = 7, 17.9%) than for Latarjet (n = 2, 2.5%) interventions. Being under the age of 20 years was a significant risk factor for recurrence (P = .007). Return to sport was significantly more frequent among sportspeople undergoing Latarjet procedures, for both training (P = .031) and competition (P = .038), and was also significantly more rapid for training (P = .034) with a mean time to return to training of 5.1 months for Latarjet procedures, versus 6.4 months for Bankart procedures. CONCLUSION: The Latarjet surgical technique results in fewer recurrences than the Bankart technique, with a higher rate of return to sport (training, competition) and a faster return to training for sportspeople practicing potentially risky sports in competition. Age was also identified as an additional risk factor for recurrence. It is important to take these factors into account when considering the indications for surgery.
