Meta Analysis

Abstract

Background: Patellar fractures are about 1% of adult fractures. A growing tendency is evident in the age-specific incidence distribution. 55% of all patellar fractures considered comminuted fractures and surgically repaired.

Aim of the study: was to synthesise the available data addressing the safety and efficacy of modified cerclage wiring(MCW) and locked patellar plate (LPP) for the fixation of comminuted fracture patella.

Methodology: MEDLINE via PubMed, CENTRAL, and Google scholar databases were searched using the relevant keywords to discover the eligible citations. Screening, data extraction, and quality assessment were performed independently. The Open Meta-analyst software was used to perform the single-arm meta-analysis.

Results: We included 11 studies (LPP= 193 patients and MCW= 53 patients). Regarding LPP, the pooled data showed that the VAS score was 0.801, 95% CI (0.331 to 1.271), Knee flexion was 128.84°, 95% CI (121.05° to 136.62°), Lysholm score was 92.41, 95% CI (89.24 to 95.57), and Tegner score was 3.29, 95% CI (2.97 to 3.61). In terms of MCW, the knee flexion was 128.71°, 95% CI (125.32° to 132.09°), and the Böstman score was 28.37, 95% CI (27.71 to 29.04). The complication rate in patients treated with LPP was 3.9%, 95% CI (1.0% to 6.9%), whereas, in MCW patients.

Conclusion: The available evidence indicates that LPP operation safe and efficient in improving the clinical performance of cases with communicated patellar fracture, with satisfactory results, enhanced QoL, and low complication rate. MCW effectively achieved excellent performance in most treated patients, with no complications.
