Abstract

Objective: Mobile bearing dislocation following Oxford Unicompartmental Knee Arthroplasty (UKA) is one of the most common causes of revision surgery. However, there have been no studies on the predisposing factors for this complication. Hence, in this study, we evaluated the preoperative risk factors for mobile bearing dislocation.
Methods: A total of 478 knees underwent Oxford UKA from 2010 to 2016 in our institution. Among these, 20 knees had mobile bearing dislocation, but only 19 knees were included in this study as there was no pre-operative MR data for one knee. By matching sex and age, thirty-eight knees were selected for the control group, which did not have dislocation. Demographic data, preoperative risk factors including meniscal extrusion, and radiological calculations were evaluated. Using multivariate logistic regression analysis and a receiver operating characteristic curve, we determined significant risk factors.
Results: Mean Medial Meniscus (MM) extrusion was 4.6 mm in the dislocation group and 3.5 mm in the control group. Regression analysis showed that only MM extrusion was a significant factors in bearing dislocation (odds ratio, 1.592; 95% confidence interval, 1.067 to 2.375) the cut-off value was 3.16 mm.
Conclusion: Pre-operative medial meniscal extrusion is a significant risk factor in mobile bearing dislocation after Oxford UKA.
