Partial Knee Replacement Surgery

An Effective Treatment for Knee Arthritis

What is the procedure called?

Partial knee replacement surgery, also known as unicompartmental knee arthroplasty (UKA), is a surgical procedure that involves replacing a damaged or arthritic portion of the knee joint with an artificial implant.

What type of procedure is it?

UKA is a minimally invasive procedure, meaning that it involves less cutting and disruption of the tissues and bone than traditional total knee replacement surgery. It is a less extensive surgery that only replaces the damaged part of the knee joint, rather than the entire knee joint.

How long does partial knee replacement surgery usually take?

The procedure typically takes between 1-2 hours to complete, depending on the complexity of the case.

When is it recommended to have this procedure done?

Partial knee replacement surgery is usually recommended for patients who have arthritis in only one part of the knee joint, usually the inner part. It is generally recommended for patients who have not experienced relief from nonsurgical treatments, such as medication, physical therapy, or bracing.

What happens during the surgery?

During the procedure, the damaged portion of the knee joint is removed and replaced with a metal and plastic implant. The procedure is typically performed under general anesthesia. The surgeon will make a small incision and use specialized instruments to remove the damaged tissue and insert the implant.

What do you need to do before the procedure?

Before the procedure, patients are advised to stop taking blood-thinning medication, such as aspirin, for several days. They may also need to undergo certain tests, such as blood work or imaging, to ensure they are healthy enough for surgery.

What should you do after the procedure?

Patients should follow their doctor’s instructions regarding post-operative care, which may include pain management, physical therapy, and exercise. They should also avoid high-impact activities and sports that put stress on the knee joint.

What are the post-procedural recommendations?

After the surgery, patients will need to stay in the hospital for a few days to allow for proper healing and rehabilitation. They may need to use crutches or a walker to assist with mobility. Physical therapy will also be prescribed to help the patient regain strength and range of motion.

What are the possible complications, and how likely are they to occur?

As with any surgical procedure, there are risks associated with partial knee replacement surgery, including infection, blood clots, and nerve or blood vessel damage. However, the risk of complications is generally lower with UKA compared to total knee replacement surgery.

How long will you need to stay in the hospital after the procedure?

Patients typically stay in the hospital for 1-3 days following the procedure, depending on their individual circumstances and the extent of the surgery.

How long will it take to fully recover after the procedure?

Recovery time varies from patient to patient, but most patients can expect to be able to resume normal activities within 3-6 weeks after surgery. However, it may take up to a year to fully recover and regain full range of motion.
In conclusion, partial knee replacement surgery is an effective treatment option for patients with arthritis in one part of the knee joint. Compared to traditional total knee replacement surgery, it is less invasive and involves a shorter recovery time. By addressing knee pain and stiffness, UKA can improve a patient’s quality of life and allow them to return to activities they enjoy. If you are experiencing knee pain and think you may be a candidate for partial knee replacement surgery, speak with your doctor to determine the best course of treatment.
