The short answer
After knee replacement, a supervised exercise programme helps restore movement and strength. The exercise selection and progression should match your recovery. General online demonstrations cannot replace instructions from the surgeon and physiotherapist treating you.
Understanding the problem
Early rehabilitation often includes work on knee movement, muscle activation and walking. Different exercises have different purposes. Quality of movement and an appropriate level of loading matter; forcing the knee is not automatically more effective.
Care and next steps
Ask the therapist to watch your technique and explain how often to perform each prescribed exercise. Report worsening symptoms and follow the team's advice about acceptable discomfort. Do not add resistance or abandon walking aids solely to match another patient's progress.
Prepare for your consultation
Keep a short record of the exercises prescribed, the date they changed and any questions. At review, demonstrate the exercise you find hardest instead of only saying the programme is difficult. Explain the space and support available at home. Ask which functional goal the next stage addresses, such as getting out of a chair or managing a necessary flight of stairs.
Common questions
Should I copy a knee exercise video exactly?
Only use exercises and progression that your treating team has confirmed are suitable for you.
