Partial Knee Replacement in Hilo, HI
If arthritis has damaged only one part of your knee, you may not need a full knee replacement. At Peter A. Matsuura, MD., Dr. Peter A. Matsuura performs partial knee arthroplasty, also called unicompartmental knee replacement, in Hilo, HI . By replacing only the worn section of the joint, this procedure preserves healthy bone, cartilage, and ligaments and may offer a quicker recovery and a more natural-feeling knee.
How Partial Knee Replacement Works
The knee has three main compartments: the inner (medial), outer (lateral), and front (patellofemoral). Arthritis sometimes affects only one of these areas. During a partial knee replacement, Dr. Matsuura removes the damaged cartilage and bone from the affected compartment and replaces it with metal and plastic implant components, leaving the healthy parts of the knee intact.
Who Is a Candidate?
You may be a good candidate for partial knee replacement if:
- Arthritis is limited to one compartment of the knee
- Your knee ligaments, including the ACL, are healthy and stable
- You have persistent pain despite medication, injections, bracing, and exercise
- Your knee has good range of motion without significant deformity
Dr. Matsuura uses a physical exam and in-office X-rays to determine whether a partial or total knee replacement is the best choice for you.
Potential Benefits
Because a smaller portion of the knee is replaced, partial knee replacement typically involves a smaller incision, less blood loss, and less disruption of surrounding tissue. Many patients report that their knee bends more naturally and feels more like their own knee after recovery.

Partial Knee Replacement FAQs
What is a partial knee replacement?
A partial knee replacement replaces only the damaged compartment of the knee with implant components while preserving the healthy bone, cartilage, and ligaments.
How is it different from a total knee replacement?
A total knee replacement resurfaces the entire joint, while a partial replacement targets only one compartment affected by arthritis.
Am I a candidate for partial knee replacement?
Candidates typically have arthritis in one area of the knee, stable ligaments, and good range of motion. Dr. Matsuura will evaluate your knee to determine the best option.
Is recovery faster than with a total knee replacement?
Many patients experience a quicker recovery because less tissue is disturbed, though recovery varies from person to person.
How long does a partial knee replacement last?
Many partial knee replacements last for many years. Longevity depends on factors such as activity level, weight, and overall health.
Will I need physical therapy?
Yes. Rehabilitation exercises are an important part of restoring strength and motion after surgery.
