Unicompartmental / Partial Knee Replacement

What is Partial Knee Replacement?

Partial knee replacement, also known as unicompartmental knee replacement, is a surgical procedure in which only the damaged portion of the knee joint is replaced with artificial components. The healthy cartilage, bone, and ligaments in the rest of the knee are preserved, allowing for more natural knee movement compared to Total Knee Replacement.

What are the Benefits of Partial Knee Replacement?

Partial knee replacement offers several advantages for patients who have arthritis limited to one compartment of the knee. Benefits may include:

• Smaller incision and less tissue damage
• Less postoperative pain
• Faster recovery and rehabilitation
• More natural knee movement
• Preservation of healthy bone and ligaments
• Shorter hospital stay
• Less blood loss during surgery

When is Partial Knee Replacement Recommended?

Partial knee replacement may be recommended for patients with arthritis limited to one part of the knee joint, including:

• Osteoarthritis affecting one knee compartment
• Knee Pain localized to one side of the knee
• Good knee stability with intact ligaments
• Failure of conservative treatments such as medications, injections, or physical therapy
• Patients who are not yet candidates for Total Knee Replacement

What Does Preparation for Partial Knee Replacement Involve?

Preparation for partial knee replacement involves a thorough medical evaluation, physical examination, and imaging studies such as X-rays or MRI to confirm that arthritis is limited to one compartment of the knee. Patients may also require blood tests, medical clearance, and preoperative instructions regarding medications and physical therapy.

How is Partial Knee Replacement Performed?

Partial knee replacement is performed under anesthesia. During the procedure, the surgeon makes a small incision over the knee and removes the damaged cartilage and bone from the affected compartment of the knee. The damaged surfaces are then replaced with metal and plastic components to restore smooth joint movement while preserving the healthy parts of the knee. The incision is then closed after confirming proper alignment and stability.

What to Expect During Recovery After Partial Knee Replacement?

After partial knee replacement, patients usually begin walking with assistance shortly after surgery and start physical therapy to restore strength and knee motion. Recovery is typically faster than Total Knee Replacement because less bone and tissue are involved. Many patients return to normal daily activities within several weeks, although full recovery may take a few months.

What are the Risks and Complications of Partial Knee Replacement?

As with any surgical procedure, partial knee replacement has potential risks and complications, including:

• Infection
• Blood clots
• Knee stiffness
• Implant loosening or wear over time
• Nerve or blood vessel injury
• Persistent pain or swelling
• Progression of arthritis in other parts of the knee
