Knee Replacement Market Size, Share, and Growth Forecast Report 2024–2032

In-depth Analysis by Product Type, Implant Type, End-User, Region & Key Players

Executive Summary

The global knee replacement market is projected to reach US$ 16.46 Billion by 2032, up from US$ 10.75 Billion in 2023, registering a CAGR of 4.85% from 2024 to 2032. This growth is driven by an aging population, rising prevalence of osteoarthritis, technological innovations, and increasing awareness regarding joint health and quality of life.

Introduction to Knee Replacement Surgery

Knee replacement, or knee arthroplasty, is a surgical procedure designed to relieve pain and restore mobility in severely diseased or injured knee joints. Common conditions requiring this procedure include osteoarthritis, trauma, and degenerative joint diseases. The surgery involves replacing the damaged joint with prosthetics made of metal, plastic, or ceramic components designed to mimic natural movement.

Market Dynamics

Market Drivers

1. Aging Population

• According to the UN World Population Prospects 2022, individuals aged 65+ will make up 16% of the global population by 2050, compared to 10% in 2022.
• Elderly individuals are highly susceptible to osteoarthritis, increasing the demand for knee replacement surgeries.

2. Rising Osteoarthritis Incidence

• Obesity and sedentary lifestyles are accelerating osteoarthritis prevalence.
• PubMed Central (2022) indicates over 10% of those aged 60+ globally suffer from osteoarthritis.
• Increased awareness and diagnostic capabilities further elevate surgical demand.

3. Technological Advancements

• Innovations include:
• Robotic-assisted surgeries (e.g., Stryker’s Mako system)
• Smart implants (e.g., Zimmer Biomet’s Persona IQ)
• Advanced biomaterials offering longer durability and biocompatibility
• Minimally invasive surgeries reduce hospital stays and improve recovery outcomes.

Market Restraints

1. High Procedure Costs

• Total cost includes surgery, hospitalization, rehabilitation, and post-operative care.
• Limited insurance coverage and economic disparities restrict access, especially in low-income nations.

2. Surgical Risks and Complications

• Despite advancements, patients face risks such as:
• Infection
• Blood clots
• Implant failure
• Long recovery periods
• Pre-existing conditions like diabetes or obesity further complicate recovery.
