Partial Knee Replacement Surgery
Partial knee replacement, also called a unicompartmental knee replacement, is a procedure that may be considered for treatment of severe arthritis of the knee.
Traditionally, patients have undergone total knee replacement (also called "arthroplasty") for severe arthritis of the knee joint. In a total knee replacement, all cartilage is removed from the knee joint, and replaced with a metal prosthetic implant.
Partial knee replacement uses a smaller incision and has faster recovery time as it is a minimally invasive procedure.
You don’t have to choose between the pain of doing nothing and the pain of a total knee replacement. When it comes to knee conditions, you may have the option of a partial knee replacement procedure is far less invasive than a total replacement.
The goal the surgery is to decrease pain and restore function with the least amount of pain and discomfort possible. If you have osteoarthritis that is limited to just one part of your knee you may be a candidate for partial knee replacement.
Your knee is divided into three major compartments: The medial (the inside part of the knee), the lateral (the outside part), and the patellofemoral (the front of the knee between the kneecap and thighbone).
In a unicompartmental knee replacement, only the damaged compartment is replaced with metal and plastic. The healthy cartilage and bone in the rest of the knee is left alone.
Research studies have shown that partial knee replacement performs very well in the vast majority of patients who are able to receive this procedure
Advantages of partial knee replacement over total knee replacement
- Quicker recovery
- Less pain after surgery
- Less blood loss
- Less hospital time
- More natural feel
It’s less painful, with a smaller incision and less bone and soft tissue are removed. The knee feels much more natural with up to 2/3 of your own knee remaining, and the recovery is much faster, too.
A partial knee replacement operation typically lasts between 1 and 2 hours. Your surgeon will make an incision at the front of your knee, then explore the three compartments of your knee to check that the cartilage damage is limited to one compartment and that your other ligaments are intact.
Since a partial knee replacement procedure is done through a less invasive incision the hospitalization time is shorter, and rehabilitation and return to normal activities is faster.
Patients usually experience less postoperative pain, less swelling, and have easier rehabilitation than patients undergoing total knee replacement.
