Partial knee replacement, also called partial knee arthroplasty or unicompartmental knee arthroplasty, is a type of knee replacement surgery that involves the replacement of only one part of the knee joint. The part of the knee joint to be replaced depends on the damage to the knee joint.
During the surgery, the surgeon may replace the medial part of the knee, the lateral part or the kneecap. It is very similar to total knee replacement, but the size and shape of the knee implant varies based on the part of the knee being replaced.
Partial knee replacement has smaller incisions compared to total knee replacement, therefore, it generally provides quicker recovery.

Partial knee replacement is most commonly performed in patients with knee arthritis that is limited to just one part of the knee joint. Your orthopedic doctor may recommend partial knee replacement surgery to you if you have severe knee pain that keeps you up at night or if it prevents you from performing your day to day activities.
However, to be eligible for partial knee replacement over total knee replacement, you must have arthritic degeneration or damage limited to one part of the knee, with an overall good range of motion and intact ligaments in the rest of the knee.
Before the surgery, you must prepare thoroughly to aid your recovery and prevent chances of future complications. Some preparatory steps to follow before partial knee replacement surgery are:

Before the surgery, the surgeon will perform a detailed diagnosis to determine whether the patient should have a partial or total knee replacement. Diagnostic tests to be performed before partial knee replacement are:
Once the diagnosis has been confirmed and the treatment plan has been determined, the surgeon will perform the surgery. The surgery can be performed under either spinal or general anesthesia. When the anesthesia has taken effect, the surgeon will make a 3-5 inch incision over the knee joint. Then, he will remove the damaged parts of the knee.
Following that, the surgeon will place the implant into its place and attach it using bone cement. Then, the incision will be closed and sutured. After the surgery, you will be moved to a hospital room for observation.
Compared to total knee replacement, partial knee replacement preserves more of the healthy bone and soft tissues in the knee joint. This allows the patient a shorter recovery period and protection from future complications. It also provides the patients better range of knee motion and function after recovery.
After partial knee replacement surgery, you may be able to go home on the same day or the next day. You can put a little weight on your knee right away, but you should use a cane or walker for support while walking.
Generally, the recovery period for partial knee replacement is shorter than total knee replacement. You will probably be able to walk without a support or assistive device around 3 to 4 weeks after the surgery. However, you need at least 3-4 months of physiotherapy to ensure complete joint movement after the surgery.
Though you can perform most exercises after physiotherapy, you should still avoid high-impact activities to prevent implant damage or displacement.
Some common tips you should follow for better recovery after partial knee replacement are:
There are two approaches a surgeon can follow for partial knee replacement surgery – open and minimally invasive. For open surgery, the surgery requires a large incision and significant damage to the tissues surrounding the operative site.
However, for minimally invasive surgery, the incision is smaller, which enables quicker recovery and protects the patient from potential complications after the surgery.
Your surgeon will choose the approach for your surgery based on the results of your diagnostic tests, your budget, age, recuperative ability, type of implant selected, etc.
The most common risks associated with partial knee replacement surgery are:
Yes, partial knee replacement is preferred over total knee replacement as it preserves more natural knee ligaments, thereby providing better range of motion and knee function after recovery.
According to various research studies, partial knee replacement has a success rate of over 90% over a period of 10 years. Many patients have had no joint problems even 20 years after the surgery.
No, partial knee replacement is not a treatment for arthritis. Instead, it helps get rid of damaged parts of a joint and restore the joint motion with the help of an implant.
Though, you can undergo partial knee replacement at any age if you need it and fulfill the patient selection criteria, the surgery is generally recommended to relatively younger people, i.e. between 55-64 years of age. This allows them better range of motion for a decade or so, before they need to replace the implant and get another surgery.
