Glenoid bone loss and Hill‐Sachs width percentage score are useful to select optimal operation for the treatment of glenohumeral instability in overhead athletes: Arthroscopic Bankart repair with remplissage versus open Latarjet

Abstract

PurposeGlenohumeral instability with combined bone lesion in contact and overhead athletes with subcritical bone loss is challenging to treat with high recurrent instability. Treatment options are arthroscopic Bankart repair with remplissage and Latarjet operations. However, there is no consensus on their effectiveness. This study aims to compare the clinical outcomes and return to sports after both operations and whether evaluating the glenoid bone loss and Hill‐Sachs width to calculate the total bone loss can help determine the appropriate operation.MethodsIn this retrospective comparative analysis, 30 athletes who underwent index arthroscopic Bankart repair with remplissage (n = 16) or Latarjet procedure (n = 14) between 2017 and 2020 were included. Computed tomography (CT) and magnetic resonance imaging (MRI) were routinely performed. The quick Disabilities of the Arm, Shoulder and Hand (qDASH), American Shoulder and Elbow Surgeons (ASES), instability severity index (ISI) scores and range of motion (ROM) were recorded preoperatively and at a mean follow‐up of 53 months (SD = 12). Follow‐up included time‐to‐return sports, self‐perceived sports performance level and complications/recurrent dislocations.ResultsPreoperative qDASH, ASES, ISI scores, ages and genders were similar. The Latarjet group had significantly larger glenoid bone loss, Hill‐Sachs width and total bone loss (p < 0.01). Both groups had significant improvement in patient‐reported outcomes (PROs) after the operations (p < 0.01). Athletes with a total bone loss <25% underwent arthroscopic Bankart repair with remplissage and total bone loss ≥25% underwent Latarjet procedure, and there were no differences between the groups in terms of postoperative PROs, ROM, time‐to‐return sports and performance. There were no re‐dislocations.ConclusionArthroscopic Bankart repair with remplissage or Latarjet procedure can adequately address glenohumeral instability with combined bone lesions. Patients with total bone loss scores greater than or equal to 25 may particularly benefit from the Latarjet procedure, while the minimally invasive arthroscopic Bankart repair with remplissage can yield equally satisfying scores for total bone loss less than 25.Level of EvidenceLevel III.
