How long is physiotherapy needed after knee replacement?

There is no single fixed period of physiotherapy after knee replacement because patients recover at different speeds. Rehabilitation generally begins very soon after surgery, often while the patient is still in hospital. Early goals include getting out of bed safely, walking with support, improving knee movement, and activating the muscles around the knee.

During the following weeks, exercises are usually progressed to improve bending and straightening, strength, balance, and walking ability. Many patients continue structured exercises for several weeks, while strengthening and mobility work may continue for a few months. Some need supervised physiotherapy for longer because of stiffness, weakness, balance problems, or other medical conditions.

The decision to reduce or stop formal physiotherapy should be based on function rather than a calendar date. A patient should be able to walk safely, manage daily activities, and continue an appropriate exercise programme independently. Regular follow-up helps identify whether additional physiotherapy is needed to improve movement or strength.

The quality and consistency of the exercises are usually more important than the total number of appointments. Patients who can safely perform the programme at home may need fewer supervised visits, while those with stiffness, weakness, balance problems, or slower progress may benefit from longer professional support. Any exercise plan should be adjusted if pain or swelling remains excessive.
