Knee Replacement Market Size & Forecast 2026–2034: A Global Shift Toward Mobility, Longevity, and Advanced Orthopedic Care
Rising osteoarthritis cases, robotic surgery adoption, and aging populations reshape the future of knee replacement worldwide
Global Knee Replacement Market Outlook
The global knee replacement market is projected to experience steady growth, expanding from US$ 13.82 billion in 2025 to US$ 21.48 billion by 2034, registering a Compound Annual Growth Rate (CAGR) of 5.02% during the forecast period from 2026 to 2034, according to Renub Research.
This growth is being fueled by the rising burden of osteoarthritis, expanding elderly populations, increasing sports injuries, and rapid advancements in implant materials and surgical technologies. As healthcare systems focus on improving quality of life and long-term mobility, knee replacement procedures are gaining widespread acceptance across both developed and emerging economies.
Understanding Knee Replacement Surgery
Knee replacement, medically referred to as knee arthroplasty, is a surgical procedure in which damaged or worn surfaces of the knee joint are replaced with artificial implants made from metal, ceramic, or medical-grade plastic. The procedure is primarily performed to relieve chronic pain, restore joint function, and enhance mobility in patients suffering from:
Osteoarthritis
Rheumatoid arthritis
Post-traumatic arthritis
Severe knee injuries
Knee replacement can be partial, where only the affected compartment is replaced, or total, where the entire joint is resurfaced. With advancements in minimally invasive techniques, robotic assistance, and personalized implants, patient outcomes and recovery times have improved significantly over the last decade.
Key Growth Drivers of the Knee Replacement Market
Rising Prevalence of Osteoarthritis and Joint Disorders
Osteoarthritis (OA) is the single most significant driver of the global knee replacement market. In 2019, approximately 528 million people worldwide were living with osteoarthritis, representing a 113% increase since 1990. Of all musculoskeletal disorders, OA accounts for nearly 50% of cases, and knee OA remains the leading cause of disability among older adults.
Aging populations, rising obesity rates, and sedentary lifestyles are accelerating joint degeneration worldwide. Additionally, sports injuries and post-traumatic arthritis are increasing demand among younger demographics. When conservative treatments such as medication and physiotherapy fail, knee replacement becomes the most effective long-term solution.
Advancements in Implant Design and Surgical Technology
Technological innovation has transformed knee replacement surgery from a high-risk, long-recovery procedure into a highly precise and predictable intervention. Modern implants now feature:

Day 4 of Quitting
If this is how sobriety feels, maybe it’s better to go through life a little buzzed… this, along with other hits like, I want to kill myself, I wish I was dead, and I’m going to throw myself off a bridge have been the only thoughts on rotation these past few days. I promise myself that if, in a month, I still feel like this (‘this’ meaning despondent, full of rage, and simultaneously numb) I can go back to smoking. Until mid-February though? Nicotine is off the table.
