Partial Knee Replacement

What is a Partial Knee Replacement?

Partial knee replacement is a surgical option for patients whose knee damage is limited to one area of the joint, typically caused by osteoarthritis or localized cartilage damage. In this procedure, only the affected compartment of the knee is replaced, while the healthy cartilage, ligaments, and bone in other parts of the knee are left intact. This differs from a total knee replacement, where the entire knee joint is replaced. By retaining much of your natural knee, the partial replacement can provide a more natural feeling post-surgery and preserve better knee function.

The surgery is done through smaller incisions than those required for a total knee replacement, reducing trauma to the surrounding tissues. This technique is often considered a minimally invasive procedure. During the surgery, the damaged portion of the knee is removed and replaced with a metal and plastic implant that mimics the movement of a healthy knee joint. This procedure can be performed on the inner (medial), outer (lateral), or kneecap (patellofemoral) part of the knee, depending on where the damage is located.

Benefits of Partial Knee Replacement

Partial knee replacement offers several advantages compared to total knee replacement. One of the key benefits is a shorter recovery time. Because less bone and tissue are disturbed during surgery, patients typically experience less pain and swelling postoperatively. Additionally, the smaller incisions lead to less scarring and a faster return to normal daily activities. Many patients are able to walk within a day or two following the procedure, and physical therapy helps to quickly regain strength and mobility.

Another important advantage is the retention of more of the natural knee structure, which can lead to a more natural feeling during movement. Patients often report better range of motion and a more stable knee joint. This procedure is particularly beneficial for younger, active patients with localized arthritis who are not yet ready for total knee replacement but are seeking pain relief and improved function. Furthermore, by preserving the healthy parts of the knee, there is potential for easier revision to a total knee replacement if it becomes necessary in the future.

Who is a Candidate for Partial Knee Replacement?

Partial knee replacement is typically recommended for patients with moderate osteoarthritis limited to one part of the knee. These patients often experience localized pain and swelling, but the rest of the knee joint remains healthy. Ideal candidates for this procedure are usually over the age of 45 and have tried conservative treatments, such as medications, injections, and physical therapy, but have not found lasting relief. Importantly, patients should still have a good range of motion in the knee and intact ligaments, as these factors contribute to the success of the surgery. During your evaluation, your surgeon will use X-rays and possibly an MRI to confirm the extent of arthritis and determine if a partial knee replacement is the best option.

This procedure is not suitable for patients with widespread arthritis or significant damage to more than one area of the knee. In those cases, a total knee replacement may be more appropriate. Additionally, patients with inflammatory conditions, such as rheumatoid arthritis, may not be good candidates for partial knee replacement, as the disease tends to affect multiple parts of the joint. An experienced orthopaedic surgeon will assess your condition, taking into account your age, activity level, and overall health, to make the best recommendation for your long-term knee function.

Recovery and Long-Term Outlook

Recovery from partial knee replacement is generally quicker than from total knee replacement. Most patients are able to stand and walk with assistance within a day or two of surgery, and many return home within 1 to 2 days. A tailored physical therapy plan will help you regain strength, flexibility, and balance, allowing you to return to light activities such as walking, driving, and swimming within a few weeks. High-impact activities, such as running and jumping, should be avoided to protect the implant and extend its lifespan.

The long-term outlook after partial knee replacement is highly positive for most patients. The implant used during surgery can last 10 to 15 years or longer, depending on activity level and overall knee health. Many patients experience significant pain relief, improved mobility, and better quality of life after the procedure. Regular follow-ups with your surgeon will help monitor the health of the implant and ensure long-term success. In the rare case that the arthritis progresses to other parts of the knee, a total knee replacement can still be performed in the future.
