The lateral ligament or lateral collateral ligament or LCL for short connects the femur or thigh bone to the top of the fibula bone in the lower leg. The ligament itself is a narrow strong cord of collagen fibres and its function is to provide stability to the outside of the knee.
The posterior cruciate ligament (PCL) is a ligament within the knee. Ligaments are tough bands of tissue that connect bones. Ligaments are tough bands of tissue that connect bones. The PCL -- similar to the anterior cruciate ligament (ACL) -- connects the thigh bone (femur) to your shin bone (tibia). Although it is larger and stronger than the ACL, the PCL can be torn.
Injuries of the muscles and tendons surrounding the knee are caused by acute hyperflexion or hyperextension of the knee or by overuse. These injuries are called strains. Strains are graded similarly to sprains, with first-degree strains stretching muscle or tendon fibers but not tearing them, second-degree strains partially tearing the muscle tendon unit, and third-degree strains completely tearing it.
The result can be severe knee pain. What Is Tendinitis? Tendinitis is an inflammation of the tendon, a flexible band of tissue that connects the muscles to the bones. The pull of the muscles is transmitted to the bone by the tendons, which allows movement.
Unfortunately, it's quite common. In fact, a meniscal tear is one of the most frequently occurring cartilage injuries of the knee. So what is the meniscus? It's a piece of cartilage in your knee that cushions and stabilizes the joint. It protects the bones from wear and tear. But all it takes is a good twist of the knee to tear the meniscus.
