Partial Knee Replacement: Improve Knee Mobility & Restore Function
Arthritis is the inflammation of a joint that causes pain, swelling (inflammation) and stiffness. Osteoarthritis is the most common form of knee arthritis, in which the joint cartilage gradually wears away.
There are many treatments indicated for arthritis – both non-surgical and surgical. Your doctor may also recommend surgery if non-surgical treatment options such as medications, injections, and physical therapy fail to relieve the symptoms.
What Is Partial Knee Replacement Surgery?
Partial Knee Replacement Surgery, also known as unicompartmental knee replacement, is a minimally invasive surgery in which only the damaged compartment of the knee is replaced with an implant.
Total knee replacement was commonly performed for severe osteoarthritis of the knee, Partial Knee Replacement is a surgical option if the arthritis is confined to a single compartment of the knee.
The advantages of Partial Knee Replacement Surgery over total knee replacement include:
- Smaller incision
- Less blood loss
- Fast recovery
- Less postoperative pain
- Better overall range of motion
- Feels more like a natural knee
What Is the Surgical Procedure of Partial Knee Replacement Surgery?
The orthopedic surgeon performs Partial Knee Replacement Surgery according to the following procedure:
- The surgeon makes a small incision over the knee to expose the knee joint, removes only the damaged part of the meniscus, and places the implant into the bone by slightly shaping the shinbone and the thigh bone.
- The surgeon places the plastic component into the newly prepared area and secures it with bone cement.
- The surgeon removes the damaged region of the femur or thigh bone, and fixes the metal component in place using bone cement.
- The surgeon takes the knee through a range of movements, repairs the muscles and tendons, and closes the incision.
What Happens After Partial Knee Replacement Surgery?
Following Partial Knee Replacement Surgery, the patient may walk with the help of a walker or cane for the first two weeks after surgery. The patient will follow a physical therapy exercise program for four to six months to help maintain range of motion and restore strength.
What Are the Risks and Complications for Partial Knee Replacement?
As with any surgery, there are possible risks and complications for Partial Knee Replacement Surgery, which include: stiffness, infection, blood clots, ligament injuries, kneecap dislocation, wearing of the plastic liner, loosening of the implant, and damage to the nerves, blood vessels, and surrounding tissues.
