How Does Partial Knee Replacement Surgery Work?

Partial knee replacement surgery offers a less invasive option for patients with knee pain or damage confined to a specific area of the knee. If you're like many people facing a knee replacement, you may have questions about the difference between full knee replacement vs. partial knee replacement. In broad terms, a partial knee replacement is isolated to one compartment of the knee that has become compromised in some way, while a full knee replacement is used to replace the entire knee joint.

At Southwest Hip and Knee in Tempe, AZ, board-certified orthopedic surgeon Dr. Amber Randall specializes in advanced knee replacement techniques. By utilizing Kinematic® preoperative imaging and robotics during surgery, Dr. Randall customizes each procedure to fit the patient's unique anatomy, ensuring precise and accurate results. Keep reading to learn how partial knee replacement surgery works and how it can help you regain mobility and comfort.

What is partial knee replacement surgery?

Partial knee replacement, also known as unicompartmental knee replacement, is a procedure designed to replace only the damaged or diseased portion of the knee. Unlike total knee replacement, where the entire joint is replaced, partial knee replacement focuses on restoring function to one specific compartment of the knee, typically the inner or outer side. This allows for the preservation of healthy bone, cartilage, and ligaments in the unaffected areas.

Am I a candidate for partial knee replacement?

Patients who are ideal candidates for partial knee replacement often have damage limited to one part of the knee due to conditions like osteoarthritis. By addressing only the damaged portion, partial knee replacement offers a less invasive alternative with a quicker recovery time than a full knee replacement. To determine whether you may qualify for partial vs. full knee replacement, Dr. Randall will perform a thorough evaluation and consultation.

What happens during partial knee replacement?

Partial knee replacement surgery at Southwest Hip and Knee is performed using advanced techniques to ensure precision and accuracy. Dr. Randall utilizes Kinematic® preoperative imaging and robotics to plan and guide the procedure and fit the surgery to each patient's individual anatomy. During the procedure, robotics are used to guide the surgical instruments with precision. This allows Dr. Randall to remove only the damaged tissue and bone, preserving as much healthy tissue as possible. Once the damaged tissue is removed, the custom-fit implant is placed in the knee. The implant is designed to mimic the natural movement of the knee, allowing for smoother motion and less discomfort.

What are the benefits of partial knee replacement?

Partial knee replacement offers several advantages for patients when compared to a full knee replacement. Some of the key benefits of partial knee replacement vs. full replacement include:

• Less invasive surgery
• Quicker recovery time
• Preservation of healthy tissue
• Reduced risk of complications
• Improved range of motion

Because partial knee replacement surgery involves a smaller incision and less disruption to the surrounding tissues, most patients experience a faster recovery and less postoperative pain. Additionally, by preserving more of the natural knee structure, many patients report a more natural-feeling knee joint after surgery.

How long does recovery take after partial knee replacement?

Partial knee replacement recovery is typically quicker than a total knee replacement. Most patients are able to walk with assistance within a day or two of the surgery. Physical therapy is an important part of the recovery process and helps to restore strength and mobility to the knee. While individual recovery times vary, most patients can expect to return to normal activities within six weeks. Dr. Randall will provide a personalized recovery plan based on your specific needs and monitor your progress to ensure a smooth and successful recovery so that you can get back to the activities you love as soon as possible.
