Knee Replacement Market Size, Share, Trends, Growth 2024-2032

Knee replacement surgery, also known as knee arthroplasty, is a procedure that involves replacing a knee joint with artificial parts to alleviate pain and restore function typically lost due to severe arthritis or injury. In 2023, the global knee replacement market was valued at USD 10.09 billion. It is projected to grow at a Compound Annual Growth Rate (CAGR) of 4.9% during 2024-2032, expected to reach USD 15.51 billion by the end of the forecast period. This growth is primarily fueled by an aging population, technological advancements, and an increased prevalence of conditions that impair mobility such as osteoarthritis.

  • Johnson and Johnson Services Inc.: Known for its comprehensive approach to patient care, offering a wide range of implants and surgical technologies.

Frequently Asked Questions (FAQ) about the Global Knee Replacement Market

1. What is knee replacement surgery? Knee replacement surgery, also known as knee arthroplasty, involves replacing damaged or diseased parts of the knee joint with artificial components to relieve pain and restore function. This surgery is typically recommended for patients suffering from severe arthritis or significant knee injuries.

2. What are the different types of knee replacement surgeries? There are three main types of knee replacement surgeries:

  • Total Knee Replacement (TKR): Replaces all compartments of the knee joint.
  • Partial Knee Replacement (PKR): Only one part of the knee joint is replaced, suitable for patients with limited knee damage.
  • Revision Knee Replacement: Involves replacing an old knee prosthesis with a new one, usually due to wear and tear or infection.

3. What advancements are impacting the knee replacement market? Recent advancements include:

  • Robotic-Assisted Surgery: Provides surgeons with enhanced precision and better control during the procedure.
  • 3D Printing: Allows for custom implants tailored to the specific anatomy of each patient, improving fit and comfort.
  • Smart Implants: Equipped with sensors that monitor the health of the knee and the performance of the implant.

4. What are the main drivers of the knee replacement market? Key drivers include:

  • Aging Population: Increases in the elderly population result in higher prevalence of joint-related conditions that necessitate knee replacement.
  • Technological Innovations: Continuous improvements in surgical techniques and implant materials enhance the effectiveness of knee replacements.
  • Increased Demand for Improved Mobility: Growing global emphasis on maintaining an active lifestyle fuels the demand for knee surgeries.

5. What are the risks associated with knee replacement surgery? Common risks include:

  • Infection: Although rare, infections can occur at the surgery site.
  • Blood Clots: Patients may develop clots in the leg veins after surgery, which can pose serious health risks.
  • Implant Problems: Implants may wear down over time or loosen, potentially requiring revision surgery.
