Preoperative dislocations do not influence recurrence rates after Latarjet procedures
The number of preoperative episodes of dislocation did not influence postoperative instability rates or recurrence rates after a Latarjet procedure, according to a retrospective study in the American Journal of Sports Medicine.
The investigators analyzed 308 patients aged at least 18 years at the time of surgery, with a minimum 2-year follow-up. All patients had undergone a primary Latarjet procedure for recurrent anterior glenohumeral joint instability between 2013 and 2015 in one of five institutions.
Researchers compared two cohorts of patients: a first-time dislocation group (n = 83) and a recurrent dislocation group (n = 225). Study data showed that patients were predominantly young (27.8 years) men (85.4%) who were involved in a sport activity either at the competitive level (33.1%) or recreational level (58.8%).
Three techniques were used for the surgeries, depending on the surgeon’s preferences: a mini-open technique using a drill guide (Arthrex), an arthroscopic technique using a specific guide (DePuy Mitek) and two cannulated cancellous screws, and an arthroscopic technique using two cortical buttons placed through a posterior drill guide. All patients had similar postoperative protocols.
Researchers assessed patients by a questionnaire on the number of episodes of preoperative dislocations, the time between the first dislocation and surgery, recurrence of dislocation, revision surgery, the Walch-Duplay score, the Simple Shoulder Test (SST) score, and the visual analog scale (VAS) score.
Study results revealed that, at the time of the last follow-up, rate of recurrence was not significantly different between the first-time dislocation group (4.8%) and the recurrent dislocation group (3.7%). Further, the rate of reoperation also was not significantly different:6.1% in the first-time dislocation group vs. 4% in the recurrent dislocation group.
