Isolated posterolateral corner injury is an uncommon injury that could be a source of unexplained knee pain and dysfunction. Most of these patients present instability caused by concomitant ligament injuries. Numerous studies have shown open approach posterolateral repair or reconstruction surgeries to restore posterolateral rotational stability. Still, there is a certain population of patients who present posterolateral rotation instability without significant injury to the fibular collateral ligament, popliteal fibular ligament, and popliteus tendon. The posterolateral capsular ligament is critical to provide posterolateral rotation stability. In this Technical Note, with video, we show a completely arthroscopic approach to stabilize the posterolateral corner, by stabilizing the posterior lateral joint capsule with the lateral meniscus attached to the rim of the lateral tibial plateau.
