Market Growth Drivers
Increasing prevalence of osteoarthritis among the aging population is accelerating the demand for knee replacement surgeries in the US. According to Zimmer Biomet, the growing geriatric population coupled with rising obesity rates have substantially increased osteoarthritis diagnoses, which is the leading cause prompting knee replacements.
Technological advancements in knee implants and minimally invasive surgeries are fueling market expansion. Companies like Stryker are launching AI-assisted robotic surgery platforms, such as the Mako System, which increases surgical accuracy, reduces hospital stays, and improves patient recovery rates.
Market Trends
Personalized and 3D-printed knee implants are rapidly gaining traction in the US market. Companies such as Smith & Nephew are investing extensively in patient-specific instrumentation and implants, which enhance fit and increase the longevity of knee replacements, thereby improving patient satisfaction and reducing revision rates.
Adoption of outpatient and ambulatory surgical centers for knee replacement procedures is on the rise. Johnson & Johnson's DePuy Synthes has reported an uptick in outpatient procedures, attributing the trend to enhanced pain management solutions and faster rehabilitation techniques that minimize hospitalization.
Market Opportunity
Expansion into underserved rural markets presents a lucrative growth opportunity. Companies like Zimmer Biomet are partnering with telemedicine providers and mobile surgical units to increase access to advanced knee replacement surgeries in remote regions.
Development of biodegradable and smart knee implants offers significant potential for future market expansion, as demonstrated by Stryker’s ongoing R&D initiatives aimed at reducing long-term complications and improving implant performance.
US Knee Replacement Market Revenue (USD Million), 2020 - 2035
The chart illustrates a steady upward trajectory in revenue from USD 6,900 Million in 2020 to USD 19,800 Million by 2035. The market demonstrates robust year-on-year growth thanks to technological innovation, increased procedure volumes, and an expanding elderly demographic. The CAGR of 6.5% reflects ongoing investments in R&D and surgical infrastructure upgrades, with the most substantial revenue acceleration projected after 2027 as outpatient and personalized implants capture greater market share.
US Knee Replacement Market by Region, 2025
The 2025 regional market share breakdown shows the Midwest leading at 29% owing to high elderly populations and better healthcare infrastructure, followed closely by the South at 27%. The West and Northeast account for 22% and 18% respectively, while other regions contribute a combined 4%. The Midwest dominance is due in part to significant investments by companies such as Stryker and Zimmer Biomet in regional surgical centers.
Recent Developments in the US Knee Replacement Market
In February 2024, Stryker announced the commercial launch of its next-generation Triathlon® SmartRobotics™ system. The new system, designed for enhanced intraoperative efficiency and patient outcomes, integrates artificial intelligence for personalized knee replacements, aligning with the growing precision medicine trend.
In March 2024, Zimmer Biomet established a partnership with Teladoc Health to expand tele-rehabilitation support for knee replacement patients post-surgery. The collaboration aims to improve remote patient monitoring, accelerate recovery times, and reduce the risk of post-operative complications by leveraging advanced digital health platforms.
In April 2024, Johnson & Johnson’s DePuy Synthes division received FDA clearance for its VELYS™ Robotic-Assisted Solution, which now offers expanded indications for total knee arthroplasty. The clearance supports broader utilization in outpatient and ambulatory settings, reflecting the market shift toward same-day discharge and minimally invasive procedures.
