Prognostic Factors of the Latarjet Procedure

Objective To investigate the factors that influence the functional results of patients submitted to the Latarjet procedure. Methods Evaluation of 26 patients submitted to surgical treatment following the Latarjet technique due to traumatic recurrent anterior dislocation of the glenohumeral joint, with glenoidal bone loss greater than 20% and/or off-track injury. The minimum follow-up time was of 12 months. The Visual Analogue Scale (VAS), The Western Ontario Shoulder Instability Index (WOSI), and the Subjective Shoulder Value (SSV) scales, as well as objective data from the participants, were evaluated. Results Most patients (84.62%) did not present recurrence of the dislocation, and 92.31% were satisfied. Regarding the functional analysis, the physical component score (PCS) and the mental component score (MCS) found were within the mean quality of life of the population. The physical symptoms, according to the WOSI, presented the best percentage (8.5%), while the worst result was observed regarding lifestyle (20%). On the VAS, pain was classified as moderate (3/10) by 15.38% of the patients (4/26). In relation to sports, patients who practice sports showed improvement in SSV parameters, which had an inverse relationship with the number of relapses. It was also observed that the shorter the time between the first dislocation and the surgery, the greater the patient's satisfaction. Conclusion Early indication of surgical treatment of anterior glenohumeral instability may provide better subjective functional results to the patient.
