There Is No Difference in Clinical Outcomes of Tibial-Based Versus Fibular-Based Posterolateral Corner Reconstruction: A Systematic Review.

Abstract

To evaluate and analyze the current literature regarding clinical outcomes after posterolateral corner reconstruction (PLCR) using fibular-based and tibial-based techniques. A systematic review of the literature was performed to evaluate patient-reported outcomes after PLCR. Embase, PubMed, and Scopus were searched from their respective inception through October 25, 2022. Studies containing patient-reported outcome scores of tibial and fibular-based PLCR were included. Outcomes collected from each study were summarized using t tests for consistently reported Tegner, Lysholm, and International Knee Documentation Committee Score. Twenty-four studies (16 with level of evidence IV, 6 with Level III, and 2 with Level II) met the inclusion criteria and included 669 patients in total. Four studies comprising 111 patients directly compared the results of tibial- and fibular-based PLCR. Mean clinical follow-up across all studies was 3.3 years. The 4 studies that reported on both tibial and fibular-based PLCR were found to have no significant differences in patient-reported outcomes with P values ranging from .0561 to .9881. Analysis of the available literature regarding tibial- and fibular-based posterolateral corner reconstruction suggests no clinical differences. Level IV, systematic review of Level II-IV studies.
