The knee joint is one of the largest joints in the body. The combination of the nature of its structure and the function that it is required to undertake makes it one of the most injured joints in the body. The knee joint consists of bone, cartilage, meniscus, ligaments, tendons and muscles. Any of these tissues can be involved in a knee injury.
Knee injuries can be the result of a single traumatic event or the accumulation of chronic stressors being placed on the knee over a prolonged period of time. Common knee injuries include fractures, osteoarthritis, meniscus injuries, chondromalacea patella, growth disorders, anterior and posterior cruciate injuries, collateral ligament injuries, muscle strains and dislocations.
Most frequently presenting symptoms include pain, stiffness or restriction in joint movement, heat, swelling, clicking or locking of the joint and weakness.
