Total Knee Replacement Market Size & Industry Report, 2033

Total Knee Replacement Market Overview

Global Total Knee Replacement market size is anticipated to be worth USD 7340.59 million in 2024 and is expected to reach USD 10085.84 million by 2033 at a CAGR of 3.6%.

The total knee replacement market is witnessing a consistent surge in global demand, driven by the rising prevalence of osteoarthritis and an aging population. In 2023, over 2.8 million total knee replacement procedures were performed globally, with the United States alone accounting for approximately 1.05 million surgeries. The number of individuals aged 60 years and older surpassed 1.1 billion globally, and with osteoarthritis affecting more than 240 million people worldwide, the need for surgical interventions has increased significantly.

Total knee replacement devices are being upgraded with innovations such as 3D-printed implants, patient-specific instrumentation, and robotic-assisted surgical tools. Robotic-assisted knee surgeries increased to over 190,000 procedures globally in 2023, with a projected rise in robotic integration across Europe and Asia. Hospitals and ambulatory surgical centers now represent over 90% of all knee replacement procedures performed, with shorter post-operative recovery times enhancing demand in outpatient settings. In 2024, over 27% of total knee replacements in the U.S. were conducted in ambulatory surgical centers.

Additionally, the transition from metal-based to advanced polymer or hybrid implants has led to over 15% growth in customized and minimally invasive knee replacement systems. These technological shifts are reshaping the landscape of knee arthroplasty procedures.

Key Findings

Top Driver reason: Increasing geriatric population coupled with the rising incidence of osteoarthritis.

Top Country/Region: The United States leads with over 1.05 million total knee replacements performed annually.

Top Segment: Hospitals account for over 65% of total knee replacement procedures worldwide.

Total Knee Replacement Market Trends

One of the most prominent trends in the total knee replacement market is the adoption of robotic-assisted surgeries. In 2023, more than 190,000 knee surgeries globally were conducted using robotic platforms, an increase from 155,000 in 2021. Robotic-assisted systems help improve precision, reduce implant misalignment, and shorten patient recovery time by 15–20%. The United States, Japan, and Germany are leading adopters of robotic technologies.

The demand for minimally invasive surgeries is also shaping the market. Approximately 700,000 minimally invasive total knee replacement procedures were conducted globally in 2023, reducing hospitalization duration by an average of 1.5 days compared to traditional methods. This trend aligns with patient preferences for reduced scarring and quicker mobility.

Moreover, patient-specific implants created through 3D imaging and CT scans are gaining traction. In 2024, over 130,000 patient-specific implants were used globally, allowing for improved anatomical fit and reduced implant failure rates.

Biocompatible materials such as polyethylene, cobalt-chromium, and ceramic components are now preferred over traditional metals. Approximately 42% of implants used in 2023 included a combination of polyethylene and ceramic components to improve durability and reduce allergic responses.

Outpatient surgeries performed in ambulatory surgical centers (ASCs) increased by over 20% between 2021 and 2023, reaching nearly 850,000 procedures in 2023. This shift is supported by enhanced surgical protocols, anesthesia techniques, and cost containment strategies.

Total Knee Replacement Market Dynamics

DRIVER

Increasing geriatric population and prevalence of osteoarthritis

Globally, the number of people aged over 60 is expected to reach 1.4 billion by 2030. Osteoarthritis affects over 240 million people worldwide, with knee osteoarthritis accounting for over 80% of total cases. In the U.S. alone, more than 32.5 million adults suffer from osteoarthritis. The condition is a primary driver of total knee replacement procedures, with approximately 85% of all knee surgeries attributed to osteoarthritis. Countries like India and China are also witnessing a spike in osteoarthritis cases, with India accounting for over 5.8 million knee replacements annually by 2023. As life expectancy increases, demand for joint-preserving and joint-replacing interventions continues to accelerate.

RESTRAINT

High cost of total knee replacement surgeries and post-operative care

Total knee replacement remains one of the most expensive elective surgical procedures. In North America, average procedural costs range between $35,000 and $50,000 per surgery. These costs increase with the inclusion of robotic assistance, customized implants, and post-surgical rehabilitation, which may add an additional $8,000 to $15,000. In countries with limited insurance coverage or government support, high out-of-pocket expenses act as a significant barrier to surgery. In low- and middle-income countries, less than 15% of patients in need of knee replacements can afford the procedure, limiting access and adoption.

OPPORTUNITY

Expansion of ambulatory surgical centers and minimally invasive techniques

Ambulatory surgical centers (ASCs) have emerged as a viable alternative to hospital-based surgical care. In 2023, over 850,000 knee replacements were performed in ASCs globally, reflecting a 20% increase from 2021. These centers offer reduced procedure costs, faster turnaround times, and shorter hospital stays—averaging 1.2 days versus 3.4 days in traditional hospitals. The availability of minimally invasive techniques further supports the growth of ASCs, as these methods lower the risk of complications and enable same-day discharge. With over 5,500 ASCs operating in the U.S. alone, this segment presents a massive opportunity for knee implant manufacturers.

CHALLENGE

Limited access to orthopedic care in rural and underdeveloped regions

One of the major challenges in the total knee replacement market is the uneven distribution of skilled orthopedic surgeons and surgical infrastructure. Sub-Saharan Africa, Southeast Asia, and parts of Latin America report fewer than 0.2 orthopedic surgeons per 10,000 people. Additionally, in 2023, over 35% of rural populations in India and Africa did not have access to a joint replacement center within 100 km. Even with portable surgical kits and mobile surgical units, logistical and economic limitations restrict deployment in remote areas. This healthcare gap hampers global market penetration despite increasing demand.

Total Knee Replacement Market Segmentation

The total knee replacement market is segmented based on the type of implant systems and healthcare settings where procedures are performed. In 2023, primary knee systems made up over 85% of the total volume, while hospitals accounted for 65% of global procedures.

By Type

Primary Knee Systems: These systems are used in initial knee replacement surgeries and accounted for more than 2.4 million procedures in 2023. These implants are preferred for patients with end-stage osteoarthritis or rheumatoid arthritis and are available in cruciate-retaining, posterior-stabilized, and mobile-bearing variants. Technological advancements have enhanced wear resistance and implant longevity, leading to a 96% success rate at 10 years post-surgery.
Partial Knee Systems: Partial knee replacements accounted for over 350,000 procedures in 2023. These implants are recommended when only one compartment of the knee is damaged. They offer quicker recovery and less bone removal. Patients undergoing partial knee replacement typically return to physical activity within 6 to 8 weeks, compared to 10–12 weeks for total replacements. The rising trend of early intervention and improved imaging supports the demand for partial implants.

By Application

Hospitals: Hospitals performed more than 1.8 million total knee replacements globally in 2023. Large orthopedic centers and multi-specialty hospitals dominate this segment due to access to advanced infrastructure, robotic assistance, and trained personnel. Hospitals also cater to complex and high-risk patients requiring intensive post-operative care.
Ambulatory Surgical Centers: ASCs performed over 850,000 total knee procedures globally in 2023. These centers have gained popularity due to reduced hospital stays, lower procedural costs, and enhanced patient turnover. In the U.S., more than 28% of total knee replacements now occur in ASCs, driven by Medicare policy changes and surgeon preferences.
