In a healthy elbow joint, the surfaces at the end of the humerus, ulna and radius ( the bones the end of which form the elbow hinge, are very smooth and covered with a strong protective tissue called cartilage. Arthritis can result from traumatic damage to the bone resulting in loss or damage to cartilage, or it can be the result of inflammation as is the case with Rheumatoid arthritis where cartilage is destroyed as the result of the body's own misguided immune reaction. When this happens the three bones rub directly together. This results in further damage to the bones surfaces which then become painful.
The knee is the elbow is not
The elbow is a hinge joint.
The three joints that make up the elbow are the radiohumeral, proximal radioulnar and the ulnohumeral.
The three main types of joints in the body are: ball-and-socket joints (hip and shoulder), hinge joints (knee and elbow), and pivot joints (neck).
Since joints are articulating surfaces, they are movable. Ball and socket joints are the shoulder and hip. Everything that moves is a joint of some kind...thumb, elbow, ankle, wrist, fingers, toes...
One way is to remove the damaged bone in the joints and replace it with total elbow replacement surgery. The decision to have this done should be made carefully and after having familiarized yourself as well as possible with the nature of your elbow joint and the in and outs of elbow replacement surgery. When undergoing total elbow replacement surgery, the natural joints are removed and replaced with an artificial hinge made of metal and plastic. This implant is inserted into the bone where the joint was forming a hinge and ending the painful contact that was being made between the forearm bones and the humerus.

the elbow and knee are hinge joints
In our joints our hinge joints are located between two bone our hinge joint is our elbow.
