Knee Replacement Flexion: What Knee Bend Should I Aim For?

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.

Knee bend is one of the main early rehabilitation goals

Flexion is the amount your knee bends. It affects sitting, stairs, getting in and out of a car and many everyday activities. Progress is influenced by pre-operative movement, swelling, pain, scar sensitivity and consistency with rehabilitation.

Do not compare one day with another

A swollen knee may temporarily bend less after a busy day. Look at the trend across several days rather than forcing the knee because a single measurement is lower.

Combine movement work with swelling control and strength

Range of motion exercises are important, but they work best alongside walking, quadriceps activation, pacing and swelling management. Rehabilitation should progress rather than becoming an endless attempt to force more bend.

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.
