Joint Solutions: Partial Knee Replacement

If only one section (compartment) of your knee has deteriorated due to osteoarthritis, our specialists may recommend that you undergo a partial knee replacement—also known as partial knee resurfacing surgery, unicompartmental knee replacement and unicondylar knee replacement. This can be performed by minimally invasive techniques including computer guided robotic assisted surgery, called MAKOplasty®.

With this minimally invasive procedure, we replace only the damaged section of your knee with a prosthesis (implant). The rest of the joint remains intact. There are a number of advantages to a partial, as opposed to total knee replacement, including:

  • A smaller incision;
  • More healthy bone and tissue preservation;
  • Greater range of motion;
  • Less pain, blood loss and potential need for transfusion;
  • Shorter recovery time; and
  • Much easier transition to a total knee replacement, should that become necessary down the road.

Returning to a Pain Free, Active Life—Sooner and Faster

Many people will be able to go home the day after the procedure. You can expect to use a walker or cane for two roughly two weeks, and be able to drive in two to three weeks. Most of our patients can return to activities such as golfing, dancing and bowling in four to six weeks.  It’s important to note that these are just estimates and that recovery and healing times vary with each person.

Partial knee replacement should relieve the osteoarthritis crippling the affected section of the knee. However, we cannot guarantee that arthritis will not develop elsewhere in the joint, which may require surgical revision or a total knee replacement.

All knee replacements can wear out over time, including total knee replacements. How long a particular implant lasts varies from patient to patient and depends on a number of factors, such as the patient’s weight, activity level and the accuracy of the implant’s placement. But recent studies have shown that for appropriately selected patients, partial knee replacements can last 10 years or more.
