Unicompartmental Knee Prosthesis Market: Introduction
According to the report, the global unicompartmental knee prosthesis market was valued at US$ 868 Mn in 2020 and is projected to expand at a CAGR of 3.5% from 2021 to 2031. Unicompartmental knee replacement is an active end-stage, unicompartmental symptomatic knee arthritis procedure. However, several aspects of the process are still being studied. These include patient requirements, implant design, and disparity between national registries, and individual case series in survival rates. These are expected to restrict the adoption of unicompartmental knee replacements.
Different types of unicompartmental knee prosthesis used for surgical procedure are fixed-bearing implant, mobile-bearing implant, medial pivot implant, and others. Unicompartmental knee prosthesis are made from different types of material such as stainless steel, cobalt-chromium alloys, titanium & titanium alloys, polyethylene, and ceramics.
The global unicompartmental knee prosthesis market is driven by increase in the geriatric population and surge in incidence of injuries related to accidents, sports, and adventure. North America dominated the global unicompartmental knee prosthesis market in 2020, and the trend is likely to continue during the forecast period. Highly structured health care industry, early adoption of new products, high prevalence rate of knee injuries, and presence of major players are expected to propel the unicompartmental knee prosthesis market in North America. Asia Pacific is likely to be a highly lucrative market for unicompartmental knee prosthesis during the forecast period. The market in the region is projected to expand at a high CAGR from 2021 to 2031.
Increase in Geriatric Population and Surge in Incidence of Injuries Related to Accidents, Sports, and Adventure to Drive Global Market
The rise in prevalence of knee disorders among the geriatric population is anticipated to propel the global unicompartmental knee prosthesis market during the forecast period. Cartilage of elderly people is prone to strain and fatigue due to less water content. This leads to arthritis and cushioning at the joints, which requires knee replacement procedure. Furthermore, other connective tissues, such as ligaments attached to the bones, become less flexible and more constrained. This is expected to drive demand for unicompartmental knee prosthesis among the geriatric population. The UN Population Division projected that the number of people aged 60 years and above will increase significantly during 2015–2030. In developed countries, the proportion of people aged 60 years and above has increased from 12% in 1950 to 22% in 2011, and is expected to reach 32% by 2050.
Accidents and incidental injuries are expected to drive the global unicompartmental knee prosthesis market during the forecast period. Knee injury is most common in sports players. Increase in knee injuries in sports such as football, basketball, and others is likely to drive the global market during the forecast period. Football is a sport that causes the most injuries, with an estimated 455,449 cases annually.
Fixed-bearing Implant to Dominate Global Unicompartmental Knee Prosthesis Market
In terms of type, the global unicompartmental knee prosthesis market has been classified into fixed-bearing implant, mobile-bearing implant, medial pivot implant, and others. The fixed-bearing implant segment dominated the global unicompartmental knee prosthesis market in 2020 and the trend is expected to continue during the forecast period. Fixed-bearing implants are most commonly used for unicompartmental knee replacement surgery. These are best suited for patients who are not overweight and who do not have an active lifestyle. Low cost of fixed-bearing implants is likely to drive the segment.
Medial pivot was the second largest segment in terms of market share in 2020. The medial pivot design incorporates a mobile bearing to more effectively replicate the natural function of the knee. It rotates, twists, bends, and flexes like a natural knee joint. These factors boost the growth of the segment.
Titanium & Titanium Alloys Held Significant Market Share
Based on material, the global unicompartmental knee prosthesis market has been divided into stainless steel, cobalt-chromium alloys, titanium & titanium alloys, polyethylene, ceramics, and others. The titanium & titanium alloys segment led the global unicompartmental knee prosthesis market in terms of revenue in 2020, and the trend is projected to continue during the forecast period.
Titanium alloys are the first choice of material for unicompartmental knee prosthesis due to high strength, low density, high immunity to corrosion, complete inertness to body environment, enhanced compatibility, low Young´s modulus, and high capacity to join with bone or other tissues.
Cobalt-chromium alloys was the second-largest segment, in terms of market share in 2020. Chromium alloys are the most commonly used materials in implant components. These metals are biocompatible, tough, durable, and will not break down inside the body. These factors boost the growth of the segment.
Use in Primary Surgical Procedure
In terms of application, the global unicompartmental knee prosthesis market has been bifurcated into primary surgical and revision surgical. The primary surgical procedure segment is likely to account for a major share of the global unicompartmental knee prosthesis market during the forecast period. Unicompartmental knee arthroplasty (UKA) is a treatment option for anteromedial osteoarthritis of the knee. The number of UKAs has increased constantly across the world in the last few decades. The segment is driven by increase in usage of unicompartmental knee prosthesis for primary surgical procedures.
The revision surgical procedure was the second-largest segment, in terms of market share in 2020. The increase in disposable income in developed countries has resulted in patients preferring revision surgery for unicompartmental knee replacement. This factor is projected to drive the segment during the forecast period.
Hospitals to be Highly Lucrative Segment
Based on end-user, the global unicompartmental knee prosthesis market has been divided into hospitals, orthopedic clinics, and ambulatory surgery centers. The hospitals segment led the market in terms of revenue in 2020, and the trend is anticipated to continue during the forecast period. Availability of most of the unicompartmental knee prosthesis devices and quick customer service are anticipated to drive the segment during the forecast period.
The ambulatory surgery centers segment held the second-largest share of the market in 2020. Increase in the number of ambulatory surgery centers in developed countries is expected to augment the segment during the forecast period.
North America to Dominate Unicompartmental Knee Prosthesis Market
In terms of region, the global unicompartmental knee prosthesis market has been segmented into North America, Europe, Asia Pacific, Latin America, and Middle East & Africa. North America dominated the global unicompartmental knee prosthesis market in 2020, followed by Europe. North America’s large market share can be ascribed to early adoption of technologically advanced products, increase in incidence of major knee diseases, new product launches, and presence of major players.
The unicompartmental knee prosthesis market in Asia Pacific is anticipated to expand at a high CAGR from 2021 to 2031. This can be ascribed to the presence of developing countries with commercial hubs, expanding business organizations, increase in geriatric population in countries such as China and Japan, improving health care infrastructure, and surge in investments by companies.
