A type of arthritis that occurs when articular cartilage, usually behind the knee, deteriorates. The golfer will typically feel a dull, achy pain and might experience swelling.
2. MENISCUS TEARS
This disc-shape cartilage between the thigh and shin bones often tears as a result of being compressed as the knee joint rotates. The golfer will feel a sharp, biting pain.
Decades of joint stress can result in a significant loss of cartilage, often on the inner and outer edges of the knee, causing bone-on-bone contact and deep-aching or sharp pain.
4. TORN ANTERIOR CRUCIATE LIGAMENT
This connective tissue in the middle of the joint can rip if the knee goes beyond its normal range of motion. A popping sound usually accompanies a tear, and swelling will occur within a few hours.
5. TORN MEDIAL COLLATERAL LIGAMENT
This ligament is located on the inner portion of the joint. Stress placed on the lead knee through impact can rip the tissue, but this is rare and the injury can heal without surgery. Swelling, soreness and bruising on the inside portion of the knee are common symptoms.
