What are the benefits of a Partial Knee Replacement?

Choosing a unicompartmental knee replacement can offer several advantages over a total knee replacement, provided you are a suitable candidate. The benefits often include:

Less Invasive Surgery

The procedure typically involves a smaller incision and less disruption to the surrounding bone and soft tissues. This means less surgical trauma, resulting in a quicker and more comfortable recovery. While the transfusion rate in total knee replacement is low (<1%), historically, unicompartmental knee replacement has an even lower transfusion rate.

Faster Recovery and Rehabilitation

Patients who undergo a partial knee replacement often experience a faster recovery. Many can walk with minimal assistance soon after surgery and return to their daily activities more quickly. Hospital stays are generally shorter, and the rehabilitation process is often less intensive compared to a total knee replacement.

More Natural Knee Movement

Because two-thirds of your knee remains untouched, the joint often feels more ‘natural’ after a partial knee replacement. The ligaments that help stabilise your knee are preserved, which helps maintain more normal joint kinematics and can result in a better range of motion.

A Bone-Preserving and Soft Tissue Sparing Option

Since only a small portion of the bone is removed, a unicompartmental knee replacement is considered a bone-preserving procedure. This can be beneficial for younger, more active patients, as it leaves more bone if conversion to a total knee replacement becomes necessary later in life.
