Cartilage breakdown may be caused by wear and tear over time. Cartilage does not heal when damaged. Instead, the body tries to heal by making more bone and this results in an irregular joint with extra bone spurs called osteophytes. The result is loss of motion due to irregular joint surfaces. In addition, the inflammation caused by the arthritis results in thickening and scarring of the joint capsule which also contributes to loss of motion.
Modified activity, e.g. eliminating weight lifting and physical therapy, which may help with flexibility, and use of anti-inflammatory medication. Cortisone injections may also be used to reduce pain.
Arthroscopic debridement will help remove some mechanical and chemical irritants in the shoulder in addition to the loose cartilage flaps or loose bodies. Alternatively, full shoulder joint replacement is the long term treatment with best results.
