Overview
New York, NY – Feb 04, 2026 – The Global Knee Replacement Market size is expected to be worth around US$ 16.19 billion by 2034 from US$ 9.75 billion in 2024, growing at a CAGR of 5.2% during the forecast period 2025 to 2034. North America held a dominant market position, capturing more than a 43.7% share and holds US$ 4.26 Billion market value for the year.
Knee replacement surgery has become a widely adopted and clinically validated procedure for patients suffering from severe knee pain and reduced mobility caused by osteoarthritis, rheumatoid arthritis, or joint injury. The procedure involves replacing damaged or worn knee joint surfaces with artificial implants designed to restore function, relieve pain, and improve overall quality of life.
With advancements in medical technology, modern knee replacement procedures are characterized by high success rates, improved implant durability, and shorter recovery timelines. The use of advanced imaging, precision surgical techniques, and biocompatible materials has significantly enhanced surgical outcomes. As a result, patients are experiencing improved joint stability, increased range of motion, and long-term pain relief.
The growing prevalence of knee-related disorders, particularly among the aging population, has contributed to the rising demand for knee replacement surgeries worldwide. In addition, increasing awareness of treatment options and improved access to orthopedic care are supporting broader adoption of the procedure. Minimally invasive techniques and enhanced rehabilitation protocols are further improving patient satisfaction and post-surgical recovery.
Healthcare providers continue to emphasize patient evaluation, personalized treatment planning, and post-operative physiotherapy as critical factors for successful outcomes. Knee replacement surgery is generally recommended when non-surgical treatments such as medication, physical therapy, and lifestyle modification no longer provide adequate relief.

Regional Analysis
North America continues to dominate the knee replacement market, supported by a high volume of patients requiring surgical intervention and strong adoption of advanced and robotic-assisted technologies. The availability of sophisticated healthcare infrastructure and relatively high procedure costs further supports regional leadership. In addition, the strong presence of major industry participants contributes to sustained market growth.
In June 2024, Johnson & Johnson MedTech announced that DePuy Synthes received FDA 510(k) clearance for the VELYS Robotic-Assisted Solution for use in Unicompartmental Knee Arthroplasty, expanding beyond its earlier approval for Total Knee Arthroplasty. This advancement is expected to accelerate adoption of robotic-assisted knee procedures.
Europe represents a substantial market due to a large eligible patient base, while the Asia-Pacific region is expected to witness notable growth, driven by rising knee disorders and improving access to orthopedic care.
Emerging trends in knee replacement
Fast shift to outpatient and ambulatory surgery centers (ASCs)
- Knee replacement is being moved from long hospital stays to same-day or short-stay care, supported by better pain control and faster rehab.
- In US Medicare joint replacements, the share done in hospital outpatient settings increased from ~14% to ~72% by 2023 (2018–2023 trend).
Registry data also show average length of stay fell from 2.9 days (2012) to 1.1 days (2023) for TKA.
Rapid growth of robotic-assisted knee replacement
- Robotic use in primary TKA reached 15.9% in 2023, and it increased materially versus 2022 (12.5%).
- A US utilization study reported robotic TKA rising from 0.01% (2008) to 8.5% (2020) and projected robotic TKA could reach ~70.1% by 2030 (model-based projection).
Cementless fixation is gaining share (selected patients)
- Cementless fixation in primary TKA increased to ~21.8% (2023) in AJRR reporting.
Implant design mix is changing (medial-congruent growth)
- Medial congruent primary TKA designs reached 32.1% of cases in 2023 (up from 24.1% in 2022 and 2.3% in 2017).
- Posterior-stabilized designs remained large at 40.8% (2023) but declined vs 2022.
Material upgrades and insert innovation are becoming standard
- Highly cross-linked polyethylene remained the largest insert material at 45.9% in primary TKA (2023).
- Patellar resurfacing is still common (87.0% of primary TKA in 2023), though it has declined over time.
Infection remains the leading driver of revision burden
- The most common reason for revision TKA in 2023 was infection (32.5%), followed by mechanical loosening (24.4%).
- In older patients with cemented constructs, AJRR highlights show overall revision rising from 0.83% at 1 year to 2.60% at 10 years (typical range ~2–3% at 10 years).
