Abstract

The PCL is the primary restraint to posterior translation of the tibia on the femur1 and is also a secondary restraint to valgus, varus, and external rotation stress to the knee joint. It is most commonly injured with a posterior directed force applied to the proximal tibia, as in a dashboard injury. Injury can also result from hyperextension and hyperflexion stress. This case report describes a lesser known mechanism of PCL injury involving torsional stress to the proximal tibia. Sports physicians must be aware that PCL injury may occur to mechanisms other than dashboard injury and posterior forces applied to the proximal tibia. Prompt diagnosis may result in hastened recovery, and future knee disability may be mitigated.
