How effective is exercise therapy for knee osteoarthritis?

Knee osteoarthritis may make stairs, squatting, rising from a chair, or longer walks harder. Strengthening the thigh, hip, and trunk muscles can improve how you control these tasks. Mobility exercises may help you reach a more comfortable bend or straighten the knee, and aerobic activity supports overall endurance.

The right starting point depends on pain, swelling, stiffness, strength, balance, and the activities you want to resume. A clinician may also look at footwear, walking pattern, and other joints. Symptoms can fluctuate, so progress is judged by function and recovery as well as discomfort.

Common building blocks include sit-to-stand practice, supported squats, step-ups, quadriceps strengthening, hip strengthening, cycling, and walking intervals. Start with a level you can control, then add resistance, repetitions, or time in small steps. If swelling or pain remains noticeably worse the next day, reduce the load and review the technique or programme.

Consistency matters more than completing an exhausting session. During a flare, shorter bouts, slower movement, or water-based exercise may keep you active while the knee settles. Exercise can be combined with other care, including advice about pacing, aids, or medication when clinically appropriate.

Arrange medical or physiotherapy review if pain persists, the knee repeatedly gives way, swelling recurs, or daily activities are shrinking. Seek prompt help after an injury with inability to bear weight, a locked knee, sudden marked swelling, fever, redness, or severe unrelenting pain.

Ask which exercises target your limitations, how to adapt them during swelling, and how to measure progress beyond pain. Discuss walking, stairs, work, and sport goals so the programme reflects the tasks you actually need to perform.
