Fat-suppressed coronal 7A axial 7B and sagittal 7C proton-density-weighted images of the knee demonstrate a significant posterolateral corner knee injury with a tendon avulsion at the femoral attachment of the popliteus arrow a complete tear of the mid-substance fibular collateral ligament short. The popliteus tendon originates from the femur just below the fibular collateral ligament and extends inferiorly and obliquely through the. The popliteus muscle arises from the proximal posterior surface of the tibia and has insertions into the posterior portion of the lateral meniscus and the femur both deep and anterior to the lateral collateral ligament.

It was first described by Barnes in 1995 1. The popliteus musculotendinous unit is unique in that the distal muscular attachment is designated the insertion and the tendinous proximal femoral attachment is designated the origin. A cause of pain on the outside of the knee Popliteus tendinitis also known as popliteus tendinopathy or tenosynovitis is a rare cause of pain at the back andor outside of the knee.

The hamstrings refer to three long posterior leg muscles which are the biceps femoris semitendinosus and semimembranosus. A high index of sucpicion and accurate palpation of the lateral aspect of the knee lead one to the diagnosis. The popliteus therefore functions to provide both static and dynamic stability to the PLC of the knee joint.
