The knee is the largest joint in your body – made up of the lower end of the thigh bone (femur), which glides on the upper end of the shin bone (tibia). The kneecap (patella) slides in a groove on the end of the thigh bone. Cartilage covers the ends of the femur, tibia and back of the kneecap. Joint fluid lubricates the knee, making it move smoothly. Ligaments and muscles help keep the knee strong and stable.

If you are experiencing pain or arthritis in your knee, your doctor may recommend partial knee replacement, also known as unicompartmental knee arthroplasty, to get you back to your normal routine and enjoying life. Unlike total knee replacement, in which the entire joint is removed, partial knee replacement surgery involves just the inside (medial) or outside (lateral) compartments of the knee, which are replaced with artificial parts.

Before considering partial knee replacement surgery, Norton Orthopedic Care specialists offer a treatment plan consisting of medications, physical therapy and/or other treatment options. We may recommend partial knee replacement when you have severe arthritis in one side of one knee and nonsurgical treatments have not provided relief.

Norton Joint Care: Education to Empower Your Journey

We understand total knee replacement surgery may sound intimidating. If surgery has been recommended for you, you may have many questions. The Norton Joint Care program includes comprehensive education and rehabilitation components, so you will know what to expect before, during and after surgery. Participation in the program typically results in less pain and a quicker recovery time. Teams of caregivers, including physicians, coaches, nurses, care managers, physical therapists, music therapists and others, are dedicated to helping you return to your full potential with your new joint.
