A 2026 study of adults with degenerative meniscal tears found that, compared with no surgery, a procedure to trim the torn parts of the meniscus did not improve pain, function, or quality of life. Treatment should prioritize physical therapy, anti-inflammatory drugs, and knee braces.

Total knee replacement can relieve pain and restore function for people with knee osteoarthritis. Innovations, such as robotic-assisted surgery, personalized 3D-printed implants, and enhanced protocols for rehabilitation and pain control, aim to further improve results.

A 2025 study found that for people with advanced knee osteoarthritis in which the damage is limited to one side of the joint, partial knee replacement is as effective as total knee replacement for pain relief and improved function and carries a similar need for additional surgeries within 10 years.

If total knee replacement is needed for both knees and symptoms in both are equally severe, bilateral knee replacement can be done, either in one surgery or in stages. Replacing both knees at once may be a good option for people under 75 with no major medical conditions and support at home.

In a 2025 study, people with knee osteoarthritis reported less pain and had less knee cartilage damage after changing their walking gait to reduce pressure on the inner part of the knee.

Complete recovery from total knee replacement surgery can take six to 12 months. Working with a physical therapist to regain strength and mobility, most people can return to normal daily function within three months. It's important to remain active once physical therapy concludes. Lower-impact activities, such as walking, hiking, biking, swimming, golfing, strength training, and aerobic activities, are recommended. High-impact activities, such as running, may shorten the life span of the implant.
