Traditionally, knee replacements were reserved for patients who were elderly with severe knee arthritis. Concerns regarding patients who undergo knee replacement at a younger age are focused on the wear of the knee replacement components. Any patient who is in their 40’s and 50’s is considered “young” for a knee replacement. However, they may still be a candidate for a knee replacement if they understand the limitations of the implant and have failed non-operative treatment.
The average age of patients today undergoing a knee replacement is 65 years old. While patients under the age of 50 are the fastest-growing segment of the population undergoing knee replacement surgery, many orthopedic surgeons have reservations.
