Knee replacement is generally performed with an aim to reduce the pain and improve the mobility and functioning of the diseased or damaged knee joint. Although total knee replacement is an excellent option for such patients, for those patients whose only one part or compartment of the joint is damaged, unicompartmental knee replacement can prove to be more beneficial and natural procedure.
It is an option for a small percentage of patients with osteoarthritis of the knee whose arthritis is confined to any one of the three condyles (medial, lateral or patellofemoral) of the knee joint.
