Valued at USD 23.47 billion in 2024, the global joint replacement devices market is projected to reach USD 24.52 billion in 2025 and USD 37.01 billion by 2034, growing at a CAGR of 4.7% during the forecast period 2025–2034. Key players include Zimmer Biomet Holdings, Inc.; Stryker; Johnson & Johnson Services, Inc.; Smith+Nephew; and Arthrex, Inc. North America held the largest share in 2024.

What Joint Replacement Devices Do

Joint replacement devices, also known as prostheses, are used in arthroplasty, a surgical procedure in which an arthritic or damaged joint is replaced with artificial components. These components are made from metals, plastics or ceramics designed to mimic the movement of a healthy joint. They alleviate severe pain and restore mobility in patients with osteoarthritis or rheumatoid arthritis when less invasive treatments fail. Hip replacement and knee replacement devices are the most common types.

Geriatric Population Expands Procedure Volumes

The growing geriatric population is propelling the joint replacement devices market. United Nations data indicates that by the late 2070s, the global population aged 65 and above is projected to reach 2.2 billion, surpassing the number of children under age 18. Older adults often experience bone wear and tear that leads to osteoarthritis and rheumatoid arthritis, necessitating replacement surgeries. Greater access to healthcare services and insurance coverage makes these procedures more accessible, while manufacturers increasingly develop innovative, durable devices tailored to elderly patients.

Rising Prevalence of Osteoarthritis

According to a report in The Lancet, cases of osteoarthritis are projected to increase by 74.9% for the knee, 48.6% for the hand and 78.6% for the hip by 2050 compared with 2020. Osteoporosis further weakens bones, raising fracture risk, particularly in the hips and knees, while rheumatoid arthritis causes inflammation and joint deformity that make movement painful and difficult. These conditions drive the need for surgical interventions and, in turn, for joint replacement devices.

Knee Replacement Leads Product Segmentation

By product, the market covers hip replacement, knee replacement and other joint categories. The knee replacement segment dominated in 2024 because of the high prevalence of osteoarthritis and the increasing number of elderly individuals requiring surgical intervention. Millions of people worldwide suffer knee joint degeneration caused by aging, obesity and repetitive stress injuries. Minimally invasive knee replacement procedures are rising, and surgeons now use robotic-assisted surgery and customized implants to improve precision and patient outcomes.

Robotic-Assisted Orthopedic Surgery Gains Ground

Advancements in robotic-assisted orthopedic surgery boost demand for joint replacement devices. Robotic technology improves precision, control and consistency, leading to better implant alignment, reduced tissue damage and improved outcomes, and it has widened the range of patients who benefit, including those with complex anatomical challenges. Johnson & Johnson's DePuy Synthes offers the VELYS Robotic-Assisted Solution to enhance the precision and personalization of knee surgery. In June 2025, Johnson & Johnson MedTech introduced the KINCISE 2 Surgical Automated System in the US for primary and revision hip and knee procedures, and in May 2025, STAR hospital in India launched a robotic system for joint replacement devices surgery.

Regional Leadership and Key Players

North America dominated in 2024 on the strength of high osteoarthritis prevalence, a rapidly aging population and advanced healthcare infrastructure, while Asia Pacific is estimated to grow at a rapid pace. Well-established manufacturers and research institutions in North America have driven continuous advances in implant materials, robotic-assisted surgeries and minimally invasive techniques, and more individuals are seeking surgical solutions for joint-related disorders. Arthrex, Inc., founded in 1981 by Reinhold Schmieding in Munich and now headquartered in Naples, Florida, is privately held and specializes in minimally invasive orthopedic products. Through its DePuy Synthes division, Johnson & Johnson offers a comprehensive portfolio of joint reconstruction solutions, and in November 2024 Johnson & Johnson MedTech unveiled new joint reconstruction solutions at the AAHKS 2024 Annual Meeting in Dallas. Other major players include Acumed LLC, B. Braun, CONMED Corporation, Enovis, Smith+Nephew, Stryker and Zimmer Biomet Holdings, Inc.
