Total Knee Replacement Market Set to Reach USD 80.6 Billion by 2035, Driven by Aging Population and Technological Advancements

The total knee replacement market, currently valued at USD 55.0 billion in 2025, is projected to expand to USD 80.6 billion by 2035. This growth represents a compound annual growth rate (CAGR) of 3.9%, signifying a strong and steady demand for knee arthroplasty procedures globally.

The increasing prevalence of knee-related disorders, such as osteoarthritis, is one of the driving factors for the expansion of the market. With the global population aging rapidly, the demand for joint replacements, particularly knee replacements, is on the rise. As the number of elderly individuals grows, so does the incidence of knee joint degeneration, leading to a surge in surgeries to alleviate pain and restore mobility.
