Partial Knee Replacement, also called a Unicompartmental Knee Replacement, is a surgery that may be considered for the treatment of arthritis of the knee. Here, only the damaged compartment is replaced with metal and plastic. The healthy cartilage and bone in the rest of the knee are left alone. It preserves almost 70% of the knee with its natural ligaments. There are three compartments in the knee:
- The medial compartment (the inside part),
- The lateral compartment (the outside part) and
- The patellofemoral compartment (the front of the knee between the kneecap and thighbone).
Advantages:The advantages of partial knee replacement include:
- Much Quicker recovery as the patient starts walking almost immediately and is up and about his or her regular activities in practically no time.
- If both knees are involved, then the other knee also can be performed early or at the same setting, thus accelerating the recovery from both knees even earlier.
- Less pain after surgery as it is performed by a Minimally invasive technique and there is hardly any tissue trauma, during surgery.
