The global knee implants market is experiencing strong and sustained growth, driven primarily by the rising prevalence of osteoarthritis, rheumatoid arthritis, and degenerative joint diseases, as well as the growing elderly population worldwide. Increasing awareness of joint replacement procedures and higher demand for improved mobility and quality of life are further accelerating the adoption of knee implants.
Continuous technological advancements are significantly improving surgical precision, reducing complication rates, and extending implant durability. These innovations are enhancing patient outcomes and strengthening physician confidence in next-generation knee replacement solutions.
Healthcare systems are also shifting toward outpatient and same-day knee replacement models, supported by improved pain management protocols and minimally invasive methods. This transition is increasing procedure volumes by lowering costs and reducing the need for extended hospital stays, ultimately boosting the demand for efficient, high-performance implant systems.
Additionally, growing investments in orthopedic infrastructure across emerging markets are broadening access to knee arthroplasty. Countries in Asia-Pacific, Latin America, and the Middle East are rapidly expanding joint-replacement capabilities as healthcare spending increases and insurance coverage improves. With rising knee-related disease burdens, ongoing advancements in implant design and surgical technologies, and expanding global adoption, the Knee Implants market is solidifying its position as a critical pillar of modern orthopedic and mobility-restoration therapy.
Key Market highlights
- North America accounted for approximately 40.2% of the global Knee Implants market in 2024, retaining its position as the leading regional contributor. This dominance is supported by a high prevalence of osteoarthritis, widespread availability of advanced orthopedic centers, strong adoption of robotic-assisted and minimally invasive knee replacement procedures, and favorable reimbursement structures in the United States and Canada.
- The Asia-Pacific region held around 19.1% of the global market in 2024 and is expected to be the fastest-growing region over the next decade. Growth is driven by increasing healthcare investment, rapid expansion of orthopedic surgery capacity, rising incidence of knee osteoarthritis due to aging populations, and improved access to joint-replacement procedures in China, India, Japan, and South Korea.
- By product, the total knee replacement (TKR) segment dominated the global knee implants market, accounting for approximately 40.2% of total revenue in 2024. TKR remains the most widely performed joint-replacement procedure worldwide due to its proven long-term efficacy, broad clinical applicability, and ability to substantially improve patient mobility and quality of life. Advances such as patient-specific implants, improved polyethylene bearing surfaces, robotics-assisted surgery, and minimally invasive techniques continue to strengthen the segment’s leadership by enhancing surgical precision, reducing recovery times, and improving implant longevity.

Global Knee Implants Market: Executive Summary
Global Knee Implants Market Dynamics: Drivers & Restraints
Driver: Increasing Prevalence of Osteoarthritis & Joint Disorders
The growing prevalence of osteoarthritis and other degenerative joint disorders is a primary driver of the global knee implants market. As populations age and lifestyle-related risk factors such as obesity, reduced physical activity, and longer life expectancy increase, more individuals experience chronic knee pain, cartilage deterioration, and mobility limitations. For instance, according to the World Health Organization (WHO), osteoarthritis affects over 300 million people globally, and the number of people requiring knee replacement is expected to rise sharply over the next decade.
In the United States alone, the American Academy of Orthopaedic Surgeons (AAOS) reports that nearly 700,000 total knee replacement surgeries are performed annually, with projections exceeding 1.2 million by 2030. Similarly, in India, the growing elderly population and rising awareness of joint replacement procedures have led to a surge in knee arthroplasty procedures. This expanding pool of patients has increased demand for advanced implant technologies, such as patient-specific implants, robotics-assisted surgery, and minimally invasive knee replacement techniques. Consequently, the rising burden of joint disease is accelerating the adoption of knee implants worldwide, driving sustained growth in the global Knee Implants market.
Restraint: High Cost of Surgery & Implants
The high cost of knee replacement surgery and implants limits market growth. In the U.S., a single procedure can cost $35,000–$70,000, while advanced technologies like robotic-assisted surgery raise costs further. In developing countries, limited insurance and out-of-pocket expenses restrict access, even when implant prices are regulated. These economic barriers reduce patient uptake and slow the adoption of premium implants, restraining overall market expansion.

Global Knee Implants Market Segmentation Analysis
The global knee implants market is segmented by type, component type, end-user and region.
Type: The total knee replacement segment is estimated to have 40.2% of the knee implants market share.
The Total Knee Replacement (TKR) segment is dominant in the global knee implants market because it addresses the most severe cases of knee joint degeneration, offering proven long-term functional outcomes and pain relief. Unlike partial knee replacements, TKR restores the entire knee joint, making it suitable for patients with widespread cartilage loss, deformities, or advanced osteoarthritis.
For instance, in the United States, nearly 700,000 total knee replacement operations are performed annually, as reported by the American Academy of Orthopaedic Surgeons (AAOS), and that number is projected to increase to more than 1.2 million by 2030. This high volume underlines TKR’s central role in managing advanced joint disease.
Moreover, advancements such as robotics-assisted surgery, patient-specific implants, and improved polyethylene materials have enhanced the precision, reliability, and lifespan of TKR implants, reinforcing its market leadership. As patients and surgeons increasingly adopt these innovations, the TKR segment continues to drive growth across the global knee implants industry.
