Cementless Partial Knee Implants Market

Cementless Partial Knee Implants Market Size

The global cementless partial knee implants market was valued at USD 789.7 million in 2024. The market is expected to reach USD 826.4 million in 2025 to USD 1.3 billion in 2034, growing at a CAGR of 5.5% during the forecast period. The high market growth is attributed to the rising infection rates contributing to a rise in knee revisions, increasing prevalence of osteoarthritis and rheumatoid arthritis, and growing preference for minimally invasive procedures.

The rising prevalence of osteoarthritis in the active and ageing population is one of the major factors fueling the market growth. According to a study conducted by The Lancet Rheumatology in 2021, 595 million people globally had osteoarthritis, with the knee joint being the most commonly impacted site. Cementless partial knee replacements are less invasive due to preserving healthy bone and ligaments, leading to quicker recovery and improved mobility compared to total knee replacement.

Furthermore, only the impaired section of the knee is treated in partial knee replacements. When performed through minimally invasive techniques, procedures tend to preserve more of the patient’s natural bone and ligaments, which improves post-operative mobility and makes the knee feel more natural. In addition, the design that eliminates the use of cement enhances biological fixation, which improves bone integration and, consequently, may increase the lifespan of the implant and circumvent certain complications associated with the application of bone cement.

Cementless partial knee implants are orthopedic devices used in unicompartmental knee arthroplasty (UKA) procedures where only one compartment of the knee joint (typically medial or lateral) is replaced without the use of bone cement to fix the implant components to the bone.

Cementless Partial Knee Implants Market Trends

The ongoing development of implant materials is aiding in unlocking growth opportunities for the market of cementless partial knee implants.

• Cementless modern smart implants are manufactured using titanium alloys, cobalt chromium, and other metals with a high degree of porosity. Cementless implants help encourage osseointegration, the biological process whereby bone directly integrates with the implant, removing the need for bone cement. This reduces the risk of inflammation resulting from cement debris and aseptic loosening.
  
• The bioactive surface coatings and plasma spray with porous structures help to better interface with living tissues, thus fostering improved biology. Rehabilitation assists patients who are able to actively participate; the quick recuperation for the active population and young patients is a boon.
  
• Clinically, there is now an adaptable option for the partially knee-installed versions that can be relied on as the changes made have resulted in improved patient satisfaction, as ranging motions, comfort, and mobility have markedly improved. Advanced materials have enabled anatomical design changes that make implants lighter while mimicking the natural biomechanics of joints.

Based on implant type, the market is segmented as fixed-bearing implants, mobile-bearing implants, medial pivot implants, and other implant types. The fixed-bearing implants segment is expected to drive business growth and expand at a CAGR of 5.3%, reaching over USD 876.2 million by 2034.

• Fixed-bearing devices are mechanically simpler than mobile-bearing systems, so they have less potential for mechanical failure. This makes them more popular among surgeons. Well-placed fixed-bearing implants have long-term survival rates of over 90% at 10 years, particularly in elderly, low-demand patients.
  
• In addition, mobile-bearing systems are usually more expensive than fixed-bearing systems because of greater complexity and additional components. The increased cost and complexity of mobile-bearing systems do not compensate for the decreased performance, which tends to limit their acceptance. Many orthopedic surgeons are trained in fixed-bearing systems, which accelerates their adoption, enhancing cost efficiency and overall system budget.
  

Based on material, the cementless partial knee implants market is segmented as titanium-based, cobalt-chromium alloys, polyethylene components, and other materials. The titanium-based segment is expected to drive business growth and expand at a CAGR of 5.4%, reaching over USD 781.8 million by 2034.

• Titanium’s biocompatibility aids in osseointegration, which is necessary for cementless implants where bone growth is required for implant integration. Compared to cobalt-chromium alloys, titanium implants have better adhesion with bone tissue and, therefore, greater resistance to loosening, which enhances the lifespan and stability of the implant.
  
• Titanium alloys have a greater strength-to-weight ratio and are, therefore, much lighter and also are not mechanically inferior to cobalt-chrome implants. This is advantageous for younger and active populations, like those undergoing partial knee replacements, who need ease of movement and comfort following the procedure.
  
• Furthermore, these implants are appropriate for individuals suffering from hypersensitivity to metals, increasing the demand for titanium implants in cases of personalized knee arthroplasty to mitigate immune reaction risks.

Based on end use, the cementless partial knee implants market is classified into hospitals, orthopedic centres, and other end users. The hospitals segment dominated the market with a revenue share of 59.9% in 2024.

• These institutions are usually the first to adopt new and innovative surgical procedures and implant technologies, thus making them a preferred site for cementless partial knee and other procedures.
  
• Modern operating and imaging facilities located in hospitals assist in better surgical planning and execution. This is important for the proper alignment and adaptation of cementless implants that depend on accurate placement and bone integration. In addition, many hospitals participate in or conduct clinical research and trials, which accelerates the adoption of newer advanced materials and designs for implants.
  
• Moreover, hospitals deal with a large patient population, especially elderly patients and those with co-existing medical problems, which makes them busy centers for orthopedic surgeries like partial knee replacement. Their ability to perform simple and complex cases consecutively leads to improved surgical and resource efficiency, which enhances the use of cementless implants.

The U.S. cementless partial knee implants market was valued at USD 324.9 million and USD 333.3 million in 2021 and 2022, respectively. The market size reached USD 353.7 million in 2024, growing from USD 343.1 million in 2023.

• The U.S. has one of the fastest demographic aging shifts in the world. As noted earlier, osteoarthritis of the knee, especially medial unicompartmental osteoarthritis, is a common problem in the elderly and remains one of the most frequent reasons for undertaking a partial knee replacement. For instance, as per a recent report published in Science Direct, there have been approximately 32.5 million cases of osteoarthritis in U.S. adults aged 18 and above in the year 2023.
  
• Additionally, there has been a noteworthy increase in outpatient orthopedic surgical procedures performed in the U.S. Ambulatory surgical centres routinely perform cementless partial knee replacements because of a historically good patient turnover due to shorter anesthesia times, minimal intraoperative blood loss, and postoperative recovery time.
  
• Further, the U.S. benefits from a well-established reimbursement infrastructure, with major private insurers and Medicare increasingly recognizing the cost-effectiveness of partial knee replacements over total knee replacements for appropriate cases.
