Knee injuries can vary from a sprain/strain injury, fracture or an injury to the cartilage or ligaments in the knee joint. If the knee ligaments or cartilage are torn, then surgery is usually recommended. Torn knee cartilage usually refers to a torn meniscus which cushions the knee joint. The common ligament injuries or tears that occur in the knee joint are:
- ACL Injury (Anterior Cruciate Ligament)
- MCL Injury (Medial Cruciate Ligament)
- PCL Injury (Posterior Cruciate Ligament)
Knee injuries can be caused by blunt trauma to the knee or, commonly, twisting of the knee joint while bearing weight or walking on an unstable surface. Very often the person who suffers a knee injury hears or feels a pop inside the knee followed by severe pain. In some cases, a knee injury can lead to traumatic arthritis in the knee joint. In the most severe cases of chronic knee pain, a knee replacement may be necessary.
