Among 12 physical therapy approaches for knee osteoarthritis compared in a 2025 study, three stood out. Knee braces, followed by hydrotherapy (exercise in water) and exercise (strength training and aerobics), were best for reducing pain and stiffness and improving physical function.

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.

Muscles that support the knee—primarily in the legs and hips—need a certain amount of elasticity to work properly. That "give" allows the joints to move through their range of motion easily. If the muscles are tight, they might cause chronic knee pain. Stretching leg muscles can improve flexibility and reduce knee discomfort. Experts recommend doing dynamic stretching before workouts and static stretching afterward. One should consult a doctor if pain persists after a few weeks.

Braces help some people cope with the pain, swelling, and stiffness of knee osteoarthritis. Examples include a knee sleeve, a compressive or stretchy tube that provides warmth and might help reduce knee swelling; an unloader brace, a long frame that fits on top of the leg and helps reduce pain by redistributing pressure on the knee; and a patella tracking brace, which combines the approaches of both knee sleeves and unloader braces to reduce knee pain, swelling, and pressure at the kneecap (patella).
