Partial Knee Replacement – Info for Midland Patients

Knee osteoarthritis is a common condition that affects millions of people worldwide, causing pain, stiffness, and decreased mobility. When non-surgical treatments fail to alleviate the symptoms, knee replacement surgery may be necessary. However, traditional total knee replacement (TKR) is associated with significant risks and long recovery times. In recent years, partial knee replacement (PKR) has emerged as an alternative option, with several advantages over TKR. In this article, we will discuss the risks and benefits of PKR and why Perth Orthopaedic and Sports Medicine is a convenient choice for Midland patients considering this procedure.

What is Partial Knee Replacement?

PKR is a surgical procedure that involves replacing only the damaged or diseased parts of the knee joint. Unlike TKR, which involves replacing the entire joint, PKR targets only the affected compartment (medial, lateral, or patellofemoral) of the knee. PKR is less invasive than TKR, with smaller incisions, less bone and tissue removed, and faster recovery times.

Benefits of Partial Knee Replacement

Several studies have shown that PKR has several benefits over TKR. These include:

  1. Faster Recovery: PKR patients typically experience less pain, swelling, and stiffness post-surgery and have a shorter hospital stay than TKR patients.
  2. Greater Range of Motion: PKR allows for a more natural range of motion than TKR, as only the damaged compartment is replaced, leaving the rest of the knee intact.
  3. Better Functionality: PKR has been shown to improve knee function and overall quality of life for patients with isolated compartmental osteoarthritis.
  4. Lower Risk of Complications: PKR has a lower risk of complications such as infection, blood loss, and nerve damage than TKR.

Risks of Partial Knee Replacement

While PKR is generally considered safe, it does carry some risks. These include:

  1. Implant Failure: The prosthetic components used in PKR can wear out or loosen over time, requiring revision surgery.
  2. Infection: Like all surgical procedures, PKR carries a risk of infection, which can be serious and require further treatment.
  3. Limited Long-Term Data: While PKR has been shown to be effective in the short-term, there is limited data on its long-term effectiveness and durability.
