Artificial Hip Knee Joints Market Size, Share and Forecast Trends - Growth Analysis and Outlook Report 2026-2030

Artificial hip and knee joints are prosthetic implants that replace deteriorated joint surfaces, most often in patients with osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, or hip/knee fractures. These implants are typically made from metal alloys, polyethylene, and ceramics, and are fixed to bone either with bone cement or via cementless press-fit designs. Demand for both primary and revision procedures is rising as life expectancy increases and patients expect to remain physically active later in life.

• •2025 market value is approximately USD 23.37 billion globally.
• •Long-run compound annual growth rate is around 4.0%.
• •Hip and knee replacements together account for the bulk of joint reconstruction procedures worldwide.

Demographic ageing is the single largest demand driver, because osteoarthritis prevalence rises sharply after age 60 and is the leading indication for joint replacement. Rising obesity rates are also increasing the incidence of knee and hip degeneration, while patients are opting for surgery earlier and at younger ages. At the same time, advances in bearing surfaces, minimally invasive techniques, and robotic-assisted surgery are improving outcomes and broadening the eligible patient pool.

• •Ageing populations in North America, Europe, and parts of Asia are expanding the pool of eligible patients.
• •Growing obesity is accelerating joint degeneration, particularly in the knee.
• •Technological improvements such as robotic-assisted arthroplasty and improved polyethylene liners are supporting higher procedure volumes.

The market is generally split by joint type (hip vs. knee), fixation method (cemented, cementless, hybrid), material (metal-on-polyethylene, ceramic-on-ceramic, ceramic-on-polyethylene), and end user (hospitals, orthopaedic clinics, ambulatory surgery centres). North America currently represents the largest regional market, followed by Europe, while Asia-Pacific is the fastest-growing region as healthcare access, disposable income, and procedure volumes expand in China, India, Japan, and South Korea.

• •Knee replacements account for a slightly larger share of procedure volume than hip replacements in most developed markets.
• •Cementless fixation is gaining share in younger, more active patients.
• •Asia-Pacific is the highest-growth region thanks to improving healthcare infrastructure and rising procedure uptake.

What are the recent trends and outlook?

Looking ahead through 2030 and beyond, the market outlook is shaped by the dual pressures of rising demand and constrained healthcare budgets. Outpatient and same-day discharge joint replacement is expanding, supported by improved perioperative protocols and reimbursement reforms, while 3D-printed patient-specific implants are moving from niche to more routine use. Continued procedure volume growth is expected, particularly in emerging markets, which should keep the sector on a steady 4-5% annual growth trajectory.

• •Outpatient and ambulatory surgery centre joint replacements are growing faster than inpatient procedures in the US.
• •3D-printed and patient-specific implants are an emerging area of competitive differentiation.
• •Emerging markets in Asia and Latin America offer the strongest long-term volume growth potential.
