Rising Prevalence of Osteoarthritis
Rising prevalence of osteoarthritis, the most common cause of knee replacements, can drive the market growth. Osteoarthritis occurs when the protective cartilage that cushions the ends of bones wears down over time. This causes friction and irritation in the joint. The knee is one of the weight-bearing joints that bears the brunt of osteoarthritis due to factors like increased life expectancy, obesity, and physical inactivity among older populations. Aging global demographic profile with a large geriatric population base has resulted in a greater population prone to knee problems and in need of knee replacement surgery. Increasing life expectancy means many more years spent suffering from age-related joint degeneration. Knee osteoarthritis most commonly affects middle-aged to elderly individuals and is more common in women. Unless concrete preventive measures are taken at the community and healthcare system level to promote physical activity and weight management, rising prevalence of OA can boost demand for knee replacement procedures.
Key Takeaways from Analyst:
Global knee replacement market is expected to witness growth due to rising geriatric population worldwide who are more prone to knee injuries and conditions like osteoarthritis. However, high cost of knee replacement surgeries and prolonged recovery time post-surgery can hamper the market growth.
North America currently dominates the market, owing to the well-established healthcare infrastructure and technology in the region. However, Asia Pacific is likely to be fastest growing market due to improving healthcare facilities and rising medical tourism in countries like India, China, and Southeast Asian nations.
Within procedure segment, total knee replacement dominates as it provides a permanent solution to chronic knee problems. Noncompartmental or partial knee replacement procedure is growing at a higher rate due to the benefits of fewer complications and faster recovery time.
There has been huge demand for revision knee replacement surgeries as more number of young active adults opt for knee replacements. This offers opportunities for market players to develop innovative solutions catering to need for revision knee joints with high durability.
Market Challenges: High cost of knee replacement surgery
The high cost of knee replacement surgery can hamper the global knee replacement market growth. Knee replacement surgery is an expensive procedure, which costs around US$ 30,000 to US$ 50,000 in the U.S. The cost varies significantly based on the country, hospital, implant used and other factors. For many patients undergoing this surgery is simply not affordable due to the massive out-of-pocket costs involved despite having health insurance coverage. This financial barrier prevents thousands of patients from opting for knee replacement each year even if these people are in severe pain and the surgery is medically necessary and warranted. According to the study published by Centers for Disease Control and Prevention (CDC), about 25% of Americans who need knee replacement surgery have decided against it primarily due to concerns over the high costs. This has led to worsening of their knee conditions and deteriorating quality of life. A knee replacement, if delayed, may also require a more extensive and complex revision surgery in future which would further drive up the costs.
Market Opportunities: Biomarker discovery for rare neurological disorders
Advancements in minimally invasive procedures can offer opportunity for the global knee replacement market growth. Traditionally, knee replacement surgeries required making large incisions and cutting of muscles, in order to access the knee joint. However, newer minimally invasive techniques allow surgeons to perform partial or total knee replacements through much smaller incisions usually 4-6 cm in length. This has dramatically reduced surgery related pain, shortened hospital stay and improved recovery time for patients. According to a study published by American Association of Hip and Knee Surgeons in 2021, patients who underwent minimally invasive partial or total knee replacement using newer techniques reported almost 50% less pain during movement and walking within the first 2 weeks of surgery as compared to traditional methods. These people were also able to perform daily activities independently much earlier without external support. The average hospital stay was reduced by 2-3 days for such patients. Faster recovery means less disruption to daily lives and quicker return to normal routines. This has made minimally invasive knee surgery more attractive to an increasing number of active, younger patients who want minimal downtime from work or lifestyle.

Insights, By Procedure- Demand for joint replacement surgeries boosts total knee replacement segment growth
In terms of procedure, total knee replacement segment is estimated to contribute the highest market share of 60.1% in 2024, owing to increasing demand for joint replacement surgeries among aging populations globally. Total knee replacement procedures help alleviate chronic joint pain and restore mobility in patients suffering from severe osteoarthritis or other degenerative conditions of the knee joint. As life expectancy rises worldwide, there has been increase in number of elderly individuals experiencing joint disorders. This rising geriatric demographic boosts demand. Lifestyle diseases like obesity exacerbate knee problems and increases the workload on weight-bearing joints at a younger age. Growing health awareness also encourages more people to opt for total knee replacement at an early stage, before the cartilage wears away completely.
Insights, By Implant Type - Material innovations boosts adoption of mobile-bearing implants
In terms of implant type, mobile-bearing implants segment is estimated to contribute the highest market share of 50.12 % in 2024. Mobile implants allow more natural knee movement by maintaining flexibility in the insert that acts as a cushion between the femoral component and tibial component.
