When Would I Need a Partial Knee Replacement?

Does your knee ache constantly? Maybe you’ve been diagnosed with arthritis in a part of your knee. You’ve tried the traditional treatments: medication, cortisone shots, and physical therapy.

You might have even lost some weight so you’re placing less pressure on the knee, but nothing has helped. It may be time for a partial knee replacement. 

New advances in partial knee replacements over the past few years are giving this type of surgery excellent results. Our board-certified surgeons at The Center for Orthopedics and Sports Medicine, P.A. perform the most advanced partial knee replacement procedures available today

These procedures give you a knee that feels natural and provides a renewed range of motion and ease of mobility. 

How does the doctor decide on a partial knee replacement?

Your board-certified orthopedic surgeon reviews your complete medical history and your past and current medications. He asks you which movements you can and can’t do because of your knee pain. 

Your physician performs a physical exam of the knee and moves it in different positions to determine when and where the pain occurs. You’ll go through a series of range of motion movements. 

X-rays further show where the damage is in your knee. You may also need an MRI to determine the status of cartilage damage. If the pain is on only one side of the knee joint or only on your kneecap and your ligaments aren’t badly damaged, you may be a candidate for a partial knee replacement, also called a unicompartmental knee replacement. 

If you wait until your arthritis is too advanced and you have arthritis throughout your knee that severely limits your mobility, your physician is going to advise you that a partial knee replacement won’t be adequate; you’ll need a full knee replacement. 

Pain and arthritis on one side of the knee joint 

If your pain and arthritis damage is on the inside of your knee, nearest to your other knee (medial arthritis) or on the outside of the knee (lateral arthritis), you’re a likely candidate for this surgery. A partial knee replacement also requires that the anterior cruciate ligament (ACL) be intact and that you still have an adequate ability to move the knee. 

Partial knee replacements at The Center for Orthopedics and Sports Medicine, P.A. for arthritis on the sides of the knees use implants inserted between the end of the femur and the top of shin bone. 

The procedure is called the Oxford® unicondylar knee replacement. The Oxford procedure removes very little bone and cartilage, leaving as much of your natural knee intact as possible. This minimally invasive procedure provides a relatively quick recovery and enables your knee joint to bend and move as naturally as possible. 

Pain and arthritis in the kneecap

If the pain is in your kneecap rather than on one side of your knee, you may also be a candidate for a different kind of partial knee replacement. Our surgeons use a recent surgical advance, the arthrosurface patellofemoral hemicap procedure, which replaces the kneecap. 

Research shows that when candidates for partial knee replacement are selected properly, the procedures have excellent results for both young and older people.
