PARTIAL KNEE REPLACEMENT

“One of my favourite surgeries. Many technical details with little margin for error. A small incision, and the patients feel great after recovery.“

Knee replacement surgery is a common procedure in Singapore. You may know of a relative or friend who has had the surgery. It is usually indicated for late stage arthritis, where the cartilage in our knees is worn out. While many are familiar with a total knee replacement, less have heard of a partial knee replacement or “half knee replacement”.

WHAT IS A PARTIAL KNEE REPLACEMENT?

A partial knee replacement can be an alternative to a total knee replacement. The surgery can done for patients with arthritis in mainly one compartment of the knee. Surgery aims to replace the diseased cartilage in the affected compartment, preserving the knee’s native ligaments and restoring it’s pre-disease alignment. This allows better stability and movement of the knee, as well as a more natural feeling for the patient after surgery. Most commonly, the medial compartment of the knee is affected by arthritis, giving pain and discomfort with movement and activity.

WHY SHOULD PATIENTS CONSIDER A PARTIAL KNEE REPLACEMENT (PKR)?

SMALLER INCISION WITH LESS TISSUE DAMAGE

The surgery uses a direct approach to the medial compartment. In most cases, the scar for the PKR is about half the length of a total knee incision. Work is confined to a single compartment and done with precise instruments, resulting in less bone loss and surrounding tissue damage.

SHORTER HOSPITAL STAY, A FASTER RECOVERY

Patients undergoing this surgery have a shorter length of stay in hospital. The average PKR patient stays for just 2 days, and has a lower 30 day readmission rate to hospital as compared with TKR patients 1 .

THE OXFORD PARTIAL KNEE

The Oxford Partial Knee was designed for patients with predominantly medial compartment knee arthritis. With knee implants and joint replacements, it’s all about track record and longevity. Every patient wishes to know “How long will my implant last? Will I need another surgery?”

EXCELLENT TRACK RECORD

In 2021, the Oxford Partial Knee celebrates it’s 45th anniversary. Since the first implantation in 1976, the implant has evolved, together with its instrumentation, to become widely adopted across the world. The UK National Joint Registry (NJR) in 2020 has published 10 year results on the Oxford Uncemented implant. It has been proven to be the best performing partial knee replacement implant on the NJR with the lowest revision rate at 10 years.

A MORE NATURAL KNEE

The anterior cruciate ligament and surrounding cartilage is preserved, restoring natural kinematics and movement. Compared with TKR patients, patients who undergo a PKR demonstrate a more physiological gait at 1 year after surgery. They also have better patient reported outcomes and Forgotten Joint Scores than their TKR counterparts.

Dr Kau was one of the early adopters of the Oxford Partial Knee in Singapore since 2016. He has worked with Zimmer Biomet on the Oxford Partial Knee and is a local and regional instructor to help educate surgeons in Singapore, Thailand and Malaysia on the application and surgery for the Oxford Partial Knee.
