Knee Replacement is Estimated to Witness High Growth Owing to Growing Prevalence of Knee Arthritis

The knee replacement market comprises knee implants and instruments used by orthopedic surgeons for replacing knee joints damaged due to arthritis, trauma, or other knee injuries. Knee replacements help relieve pain and restore mobility by resurfacing the cartilage surfaces at the ends of the femur and tibia bones, and sometimes part of the patella or kneecap bone. Metal alloys, ceramics and polyethylene polymers are commonly used materials in knee implants. Advantages of knee replacements include reduction in knee pain, ability to participate in sports and daily activities, improved quality of life, and restoration of knee movement. Knee arthritis, a degenerative joint disease which causes damage to the cartilage lining the knee joint, is a primary driver of knee replacements worldwide.

The Global knee replacement market is estimated to be valued at US$ 9.4 Bn in 2024 and is expected to exhibit a CAGR of 4.1% over the forecast period 2023 to 2030.
