The aim of knee replacement surgery is the long-term relief of pain and restoration of function.
Traditionally it has been observed that around 90 percent of total knee replacements still function well 10 or 15 years later. But today’s replacements might last longer than those numbers suggest, since the world of orthopaedic implants and surgical techniques are evolving at a quick pace. A recent study published in ‘The Lancet’ examined how long knee replacements last. As published in the April 2017 edition of the medical journal, researchers found that among nearly 55,000 people who had a knee replacement, only 3.9% required revision surgery within 10 years of surgery and 10.3% required revision by 20 years. The study showed that approximately 80% of Total Knee Replacements can last for as long as 25 years.
Unfortunately, it is difficult to predict how long your joint replacement will last and no one can be sure that your knee replacement will be the last operation needed on that joint. The life of your replaced knee depends on many factors such as your age, weight, and activity level and the occurrence of any complication like infection or a fall after the surgery. No operation is 100% successful, and nothing lasts forever but Knee replacement surgery is recognized as one of the safest and most successful types of surgery in all of medicine
