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.
The collateral ligaments are commonly injured structures in the knee. Injuries happen in many ways. Injury to a collateral ligament usually involves a significant force to the knee, such as a fall while skateboarding, skiing or a hard direct hit to the side of the leg or knee.Ligaments connect or attach bones to bones.he medial collateral ligament can tear in the middle of the ligament, where the medial collateral ligament attaches to the tibia, or where the medial collateral ligament attaches to the femur. If the force against the knee or leg is great enough other ligaments can tear as well.
