Osteoarthritis
This form of arthritis is common in persons from 50 years of age. It can also occur in younger people. What happens is that the cartilage that keeps the bones in the elbow from rubbing against each other wears away
Rheumatoid Arthritis
This happens when your immune system attacks your joints. The synovial membrane covering the joints becomes inflamed. This can damage the cartilage and lead to stiffness and pain in the elbow.
Post-traumatic Arthritis
This begins to develop after a wrist injury, where fractures and tears may damage the cartilage. This causes pain in the elbow
Elbow Instability
The elbow may become unstable when the ligaments and muscles that hold the joint together becomes damage. Elbow dislocation can also cause instability. Elbow dislocation is usually caused by an injury to the elbow
Broken bones and severe fractures
This is a very common reason for elbow replacement. if your elbow bone gets badly broken or fractured, then a shoulder replacement surgery is required. The elbow may be shattered and the supply of blood to the bones interrupted, or fractures to the elbow did not heal properly. A replacement is necessary to bring back function and mobility to the elbow.
