How Should I Sleep After a Knee Replacement?

This article provides general physiotherapy information for people recovering from surgery. Follow the advice of your own surgeon and rehabilitation team where it differs from general guidance.

Sleep disturbance is extremely common early in recovery

Pain, swelling, stiffness and difficulty finding a comfortable position can all disturb sleep after knee replacement. Night symptoms can remain bothersome even when daytime walking is improving.

Positioning should be comfortable and protect movement

Follow the advice given by your surgical team. In general, avoid creating a habit of keeping the knee permanently bent just because that position feels easier. Comfortable support, regular daytime movement and sensible swelling management can help.

Night pain does not mean rehabilitation has failed

Recovery is rarely linear. A more active day can increase night discomfort. Monitor the overall trend and contact your healthcare team if pain is severe, rapidly worsening or associated with concerning new symptoms.

A structured rehabilitation programme can make progression clearer

Recovery involves more than one exercise or milestone. The full physiotherapist-written rehabilitation eGuide brings the stages, exercises, progressions and practical recovery guidance together in one structured programme.
