When can I return to walking and sport after knee replacement?
Movement usually starts early under supervision, then progresses according to wound healing, strength, balance and pain. There is no single timetable for every activity or patient. Lower-impact activities are generally preferred; swimming requires a healed wound and clearance.

Build capacity before duration
Follow physiotherapy and walking-aid advice until movement is safe. Increase walking in short sessions and monitor pain or swelling afterward. Recovery differs with the procedure and previous fitness.
Choose suitable activities
Walking, stationary cycling and later swimming may suit many patients. Running, jumping and contact sports create greater loads and need individual discussion. Returning to tennis or similar activities depends on experience, balance and the form of play. Passing a particular number of weeks is not sufficient clearance for strenuous exercise.
When to stop and seek help
New severe pain, a fall or inability to bear weight needs assessment. Wound infection signs or sudden leg swelling require urgent contact. Chest pain or breathlessness warrants emergency care.
