Background

Primary dislocation of the patella is a common acute knee disorder in children, adolescents and young adults. While primary dislocation of the patella has traditionally been treated non-operatively, primary operative repair of the medial patella-stabilizing soft tissues has been popularized more recently and thought to reduce the risk of dislocation. However, several studies have shown substantial rates of redislocation with longer follow-up time, irrespective of treatment. The purpose of this systematic review was to compare operative and non-operative treatment for primary dislocation of the patella, regarding redislocation rates and symptoms.

Methods

Based on a systematic literature search of the medical literature from 1950 to 2010, three randomized and two quasi-randomized controlled clinical trials comparing surgical stabilization with non-operative treatment for patients with primary patellar dislocation were selected. The Risk of Bias Tool (Cochrane Handbook, 2008) was used to assess the quality of the studies included. Study results were pooled using the fixed-effects and random-effects models with mean differences and risk ratios for continuous and dichotomous variables, respectively. Heterogeneity across studies was assessed with Q test and I-square statistic. A sensitivity analysis was performed by assessing the change on effect size by eliminating each single trial.
