Management of combined injuries of the posterior cruciate ligament and posterolateral corner of the knee: a systematic review

Abstract

Background

Approximately 60% of posterior cruciate ligament (PCL) injury are associated with a posterolateral corner (PLC) tear.

Sources of data

We performed a systematic review of the literature according to the PRISMA guidelines. The following key words were searched on Medline, Cochrane, EMBASE, Google Scholar, and Ovid: 'posterior cruciate ligament' or 'PCL' with 'posterolateral corner' or 'PLC' and 'chronic'; 'injury'; 'management'; 'reconstruction'; 'outcomes'; 'complications'.

Areas of agreement

There was a statistically significant improvement of all clinical scores after surgery regardless of the procedure performed to reconstruct both PCL and PLC.

Areas of controversy

No randomized control trials were identified on the topic. Standardized methods of functional outcomes assessment are necessary to improve communication on the functional results of the management of PC–PLC.

Growing points

Single stage surgical reconstruction of PCL and PLC is recommended in patients with posterolateral rotatory instability of the knee.

Areas timely for developing research

Adequately powered randomized trials with appropriate subjective and objective outcome measures are necessary to reach definitive conclusions.
