The tendon of the popliteus passes into the joint cavity through the capsule at the back of the lateral meniscus, on its way to the side of the femur. The tendon can be seen from inside the knee during an arthroscopy.

Rupture of the popliteus tendon
Isolated rupture of the popliteus tendon can occur during an injury, but this is uncommon.
Usually other structures of the posterolateral corner are also involved.
Peer-reviewed papersQuote from peer-reviewed paper:
"...isolated rupture of the popliteus tendon is uncommon. ...Diagnosis in the acute setting can be easily overlooked but an acute haemarthrosis and posterolateral pain in an otherwise stable knee should raise suspicion of this injury.

"....Missed injuries can increase the failure rates of both anterior and posterior cruciate ligament reconstructions, while untreated injuries may lead to chronic disability."
