Global Knee Replacement Market Grows Steadily at a CAGR of 5.3%

Introduction

Knee replacement, also known as knee arthroplasty, is a surgical procedure in which a damaged or worn-out knee joint is replaced with an artificial implant. This procedure is typically performed to relieve pain and improve function in individuals suffering from severe knee arthritis or joint injuries. The surgery involves removing the damaged portions of the knee joint and replacing them with prosthetic components made from materials such as metal, plastic, and ceramics. Knee replacement can involve either partial or total joint replacement, depending on the extent of the damage. The procedure aims to restore mobility, alleviate pain, and improve the overall quality of life for patients.

Market Dynamics

Rising prevalence of osteoarthritis & joint disorders drives the global market

The growing prevalence of osteoarthritis and other joint disorders is a key driver of the knee replacement market. Patients who experience severe pain and limited mobility due to osteoarthritis, rheumatoid arthritis, or joint injuries often turn to knee replacement surgery when conservative treatments no longer provide relief.

• According to a February 2024 report by the American College of Rheumatology, the U.S. alone sees approximately 790,000 total knee replacements annually, with numbers expected to rise significantly due to an aging population. As non-surgical options like medications, physical therapy, and joint injections become less effective, knee surgery becomes the necessary next step for many individuals.

This trend underscores the increasing demand for knee replacements as healthcare professionals prioritize improving patient outcomes with advanced implant technologies and minimally invasive surgical techniques.

Advancements in biocompatible implant materials for knee replacement create tremendous opportunities

Recent advancements in biocompatible implant materials have greatly improved the longevity, integration, and clinical outcomes of knee replacements. Innovations in biomaterials, such as advanced alloys, smart implants, and 3D-printed components, are reshaping the knee replacement field. These materials not only enhance implant durability but also assist in post-operative monitoring, reducing complications and speeding up recovery.

• For example, in August 2024, Bonetech Medisys unveiled cutting-edge orthopedic technologies, including biomaterial alloys and smart implants, designed to enhance knee replacement results. These advancements provide a better fit and functionality, reducing the need for revision surgeries and improving long-term success rates.

As biocompatible implant materials continue to evolve, they present a significant opportunity to address the rising demand for customized, durable solutions in knee replacement.
