BACKGROUND: There are a variety of reported surgical techniques outcomes of chronic grade III posterolateral corner (PLC) @entity3331 . It is unknown if outcomes differ among the various surgical treatments. PURPOSE: To systematically review the literature and report subjective and objective outcomes for surgical treatment strategies for chronic grade III @entity130 to determine the optimal surgical technique. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: A systematic review of the literature including Cochrane, PubMed, Medline, and Embase was performed. The following search terms were used: posterolateral corner knee, posterolateral knee, posterolateral instability, multiligament knee, and @entity3031 . Inclusion criteria were outcome studies of surgical treatment for chronic @entity3331 with a minimum 2-year follow-up, subjective outcomes, objective outcomes including varus stability, and subgroup data on @entity130 . Two investigators independently reviewed all abstracts. Accepted definitions of varus stability on examination or stress radiographs, and the need for revision surgery, were used to categorically define success and failure. RESULTS: Fifteen studies with a total of 456 @entity1 were included in this study. The 15 studies included 5 with level 3 evidence and 10 with level 4 evidence. The mean age of the @entity1 in each study ranged from 25.2 to 40 years, the reported mean time to surgery ranged from 5.5 to 52.8 months, and the mean follow-up duration ranged from 2 to 16.3 years. Mean postoperative Lysholm scores ranged from 65.5 to 91.8; mean postoperative International Knee Documentation Committee (IKDC) scores ranged from 62.6 to 86.0. Based on objective stability, there was an overall success rate of 90% and a 10% failure rate of PLC reconstruction. A variety of surgical techniques were reported. CONCLUSION: @entity8638 were reconstructed in all studies, and while techniques varied, the surgical management of chronic @entity130 had a 90% success rate and a 10% failure rate according to the individual investigators' examination or stress radiographic assessment of objective outcomes. More than half of the 456 @entity1 had a combined posterior cruciate ligament-PLC injury. Surgical techniques included variations of fibular slings, capsular shifts, and anatomic-based techniques (fibular tunnel and tibial tunnel). Further research is needed to determine the optimal surgical technique for treating chronic grade III @entity130 .
