Partial Knee Replacement

When arthritis or an injury causes chronic knee pain, simple daily tasks can become a struggle. For patients whose joint damage is limited to one specific area, a partial knee replacement—clinically known as unicompartmental knee arthroplasty—may be a viable solution. When this procedure is appropriate for the patient, it often allows for a recovery process that feels more natural than a full knee replacement.

What is a Partial Knee Replacement?

In a partial knee replacement procedure, the surgeon focuses only on the affected section of the knee—typically the medial (inner), lateral (outer), or patellofemoral (front) compartment—removing the worn-out cartilage and bone. Because the healthy ligaments and bone in the rest of the joint are left intact, the damaged area is replaced with a small prosthetic made from high-grade plastics and metal.

By preserving more of your original anatomy, this approach often results in a joint that feels more like your natural knee after you have recovered.

Who Should Have a Partial Knee Replacement?

This surgical option is ideal for individuals whose arthritis is confined to a single compartment of the knee. You may be a strong candidate if you:

• Experience stiffness and pain localized to one specific area of the joint
• Have healthy, intact ligaments (particularly the ACL)
• Have already attempted conservative treatments—such as medications, injections, or physical therapy—without sufficient relief
• Wish to preserve as much of their natural knee structure as possible

If pain during your daily routine becomes constant and non-surgical options are no longer effective, it may be time to explore surgical intervention. Your orthopedic specialist will evaluate your condition to determine if a partial or total knee replacement is the best path forward. It is important to note that arthritis is a progressive disease; because partial replacements typically do not last as long as total ones, there is typically a distinct possibility that a full replacement could be required in the future.

How Well Does a Partial Knee Replacement Work?

For the right candidate, partial knee replacement is a highly effective treatment. Many patients report several advantages over a total replacement, including:

• A more rapid recovery period
• A joint that feels more natural during movement
• Reduced levels of postoperative pain
• Smaller surgical incisions and less disruption to the surrounding soft tissue

While total knee replacements are more common, the general recovery process is similar.
