What are the advantages of unicompartmental knee arthroplasty?

Unicompartmental knee arthroplasty (UKA), also known as unicompartmental knee replacement (UKR), is a surgical procedure that is used to treat arthritis in one compartment of the knee. Unlike a total knee replacement, which replaces the entire knee joint, a UKA only replaces the damaged compartment of the knee.

UKA offers a number of potential advantages over a total knee replacement, such as:

  • Less invasive: UKA is less invasive than a total knee replacement, with a smaller incision and less bone removal. This can result in less pain and a faster recovery time.
  • Improved range of motion: UKA can help improve the range of motion of the knee, as it preserves the healthy compartments of the knee.
  • Lower risk of complications: UKA has a lower risk of complications such as infection, blood clots, and knee stiffness compared to total knee replacement.
  • Better for younger and more active patients: UKA may be a better option for younger and more active patients, as it allows them to maintain more natural knee function and potentially resume high-impact activities.
  • Long lasting: UKA has a good longevity, with an average lifespan of 15-20 years.
  • Cost-effective: UKA is a cost-effective option compared to total knee replacement as it requires less surgical time and less implant material.

It's worth noting that UKA may not be suitable for everyone, and it is important to discuss with a medical professional about the best option for each specific case. Factors such as severe arthritis, high body mass index, and certain medical conditions may make a person a better candidate for a total knee replacement.
