Sports injuries can affect the ligaments and tendons around the knee. Ligaments are the thick bands of rubbery tissue connecting bones at the knee joint. Tendons connect the knee muscles to the bone.
Sports injuries affecting the knee are more common in activities such as football, netball, skiing, lacrosse, hockey, rugby, running, squash and tennis. Common problems include sprains, strains and ligament or tendon injuries.
One of the most frequent ligament injuries affecting the knee is a tear of the anterior cruciate ligament (ACL), which is an increasing problem in children. Other common problems include tendon injuries, meniscal tears, and kneecap (patella) instability.
