The iliofemoral ligament is a main link between the two. Ligaments arenât meant to stretch but they can. If enough pressure is exerted on a ligament it can become overstretched or tear from poor mechanics or a blunt force injury like a torn acl in football. But ligaments can also become overstretched from poor posture.
1 Medial collateral ligament (MCL) - prevents lateral movement of the tibia on the femur when valgus (away from the midline) stress is placed on the knee.2  Runs between the medial epicondyle of the femur and the anteromedial aspect of the tibia. 3  Also has a deep attachment to the medial meniscus.
