Like in the shoulder joint, younger patients suffering from osteoarthritis may benefit from surgery that puts off the need for full knee joint replacement. This type of surgery is suitable for people with severe abnormalities in knee alignment causing a misbalance in the kinematics and weight bearing, building up an uneven amount of pressure on one side of the joint and its cartilage.  The joint preservation surgery aims at getting the knee ‘back in line’ so that it is more balanced.
