Results Average time of surgery was significantly shorter in ARTHRO than OPEN: respectively 110 and 120 minutes. The number of intra-operative complications was six (12.5%) in OPEN and five (8.1%) in ARTHRO. The results were comparable in both groups, with no significant difference between OPEN and ARTHRO group: satisfaction rate -96.8% and 91.9%, shoulder function -92.2% and 90%, Walch-Duplay score -83.9 and 76.7 respecively. A significant difference was reported in Rowe score: 87.8 in OPEN and 78.9 in ARTHRO. Another significant difference was found in the presence of Bsubjective apprehension^-a term referring to the subjective perception of instability with no signs of instability at clinical examination -28.7% in OPEN and 50% in ARTHRO. Range of motion in both groups were comparable, however patients in OPEN had significantly lower loss of external rotation in adduction to the side comparing to the contralateral shoulder: 7°versus 14°in ARTHRO. Recurrence was reported in three cases in each group: 6.2% in OPEN and 4.8% in ARTHRO. A revision surgery was performed in four patients (9.3%) in OPEN and six (9.7%) in ARTHRO. Radiographic evaluation showed a significantly lower rate (5%) of graft healing problems (fracture, non-union and osteolysis) after arthroscopic stabilisation, however a partial osteolysis of the proximal part of the bone block was significantly more frequent (53.5%). Conclusions The arthroscopic Latarjet stabilisation showed satisfactory and comparable results to open procedure. We recommend further investigation and development of arthroscopic technique.Level of evidence: III

PurposeThe goal of this study was to evaluate clinical and radiological outcomes after arthroscopic Latarjet stabilisation in anterior shoulder instability.MethodsNinety-three patients after primary arthroscopic Latarjet stabilisation were reviewed. Satisfaction, subjective shoulder value (SSV), Walch–Duplay and Rowe scores, and range of motion and stability were evaluated on clinical examination. Computed tomography (CT) was used to analyse graft position and fusion.ResultsNinety patients (96.8%) were available for clinical and 85 for CT evaluation. The mean follow-up was 23.7 months (13–50, SD 7.1) and age at surgery was 26.2 years (16–44, SD 5.6). Intraoperative complications were reported in eight patients (8.9%) and recurrence in three (3.3%). Significantly, two out of three patients with recurrence had intraoperative graft complications (p = 0.0107). Forty-one patients (45.6%) reported the feeling of “subjective return to sport anxiety”. External rotation with arm at the side was 59° (10–90°, SD 20) with 15° (0–70°, SD 17) of loss of rotation. These two factors correlated with results the most. Patient satisfaction was evaluated as 92% (40–100, SD 14) and SSV 90% (30–100, SD12). Revision rate after primary surgery was 10%. CT showed graft healing in 81 (95.3%) patients. A graft position between 2 and 5 o’clock was found in 70 (83.4%) patients and flush to the anterior glenoid rim in 34 (40.5%). Osteolysis of the superior part of the graft was found in 55 (64.7%) patients. CT evaluation showed no correlation with clinical results.ConclusionArthroscopic Latarjet stabilisation demonstrates satisfactory results in short-term follow-up; however, intraoperative graft-related complications are a risk factor for recurrence. “Subjective return to sport anxiety” and loss of external rotation with the arm at the side are factors worsening the results. Graft position imperfections and osteolysis of the superior part of the graft reported in CT evaluation do not influence the clinical results.
