How long does a unicompartmental knee replacement last?

The lifespan of a unicompartmental knee replacement (UKR) can vary depending on a number of factors, such as the patient's age, weight, activity level, and overall health. However, on average, a UKR can last for 15-20 years.

  • It's important to note that UKR is not suitable for everyone, and it is important to discuss with a medical professional 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.
  • Like any joint replacement, UKR does have a risk of wearing out or loosening over time, and revision surgery may be necessary if this occurs.
  • Regular follow-up appointments with the orthopedic surgeon and physical therapy are important to monitor the knee and to ensure optimal function and longevity of the implant.
  • It's also important to note that a patient's compliance with post-operative guidelines, like weight management, avoiding high-impact activities, and taking medications as prescribed, can significantly impact the longevity of the implant.
