Stiffness after knee replacement: when the plan needs review

A knee that will not bend comfortably after replacement can make a chair, a staircase or a car seat feel like an obstacle. More force is not automatically the answer. Before choosing another procedure, the team needs to explain why movement is limited and whether the problem is still changing. The degree measured on one day is only part of that assessment.

Record movement and what it means in daily life

Bring the physiotherapist's dated measurements if they are available, including both bending and straightening. Explain whether the range has gradually improved, stopped improving or become worse after an initially better period. A note that the knee is “stiff” does not convey those different courses or the impact on ordinary activities.

Describe what prevented rehabilitation from progressing: pain, difficulty obtaining therapy, a wound problem or instructions to limit movement. This is not an exercise in assigning blame. The reviewer needs to understand the treatment actually completed rather than assume that every patient followed an identical recovery schedule from the first postoperative day.

Scar tissue is one possible explanation

AAOS describes adhesions, or arthrofibrosis, among the causes of stiffness after knee replacement. It also notes that infection or the size and position of components can lead to restricted movement. Those situations cannot all be solved by the same procedure. Nuffield Health similarly distinguishes soft-tissue tightness from a mechanical block when assessing suitability for manipulation.

Ask the clinician to state the leading explanation and whether another cause still needs investigation. If imaging or laboratory tests are requested, the question should be specific. Repeating a general rehabilitation prescription without addressing a new concern may not resolve the reason that progress has stalled.

What manipulation under anaesthesia is intended to do

Manipulation under anaesthesia, often abbreviated MUA, moves the knee while the patient is anaesthetised to address restrictive adhesions. It is not a replacement of the prosthesis. AAOS explains that component-related problems are not corrected simply by manipulation. The procedure therefore needs an appropriate diagnosis as well as a discussion of its risks and expected benefit.

Timing matters to the assessment, so persistent stiffness should be reviewed promptly with the operating team rather than left until an overseas trip becomes convenient. There is no single date in this guide that determines whether you personally should have MUA. Ask how time since surgery affects the available options in your particular case.

The recovery plan starts before the procedure

Both AAOS and Nuffield emphasise the role of subsequent rehabilitation in maintaining movement. An improved range in the operating room is not the whole treatment result. Before agreeing to MUA, establish who will organise therapy, how pain management will be coordinated and how the team will assess progress after you leave hospital.

Describe any barriers that made the first course difficult. If therapy cannot be accessed near home, that problem needs a workable answer before another intervention. Do not attempt forceful bending yourself or ask someone to reproduce a manipulation at home; the procedure takes place under medical supervision after assessment of suitability.

If another procedure is proposed instead

A recommendation for release of scar tissue or revision surgery should explain why it is addressing something that manipulation would not. Have the team separate the intended work on tissues from any proposed change to the implant. Ask which daily tasks the expected gain in movement might help and which limitations may remain.

For an opinion in Turkey, send the original operative record, follow-up notes, rehabilitation measurements and current imaging. Clarify whether the appointment is to establish the cause or to discuss an already supported treatment proposal. New drainage, a hot swollen knee with worsening symptoms or feeling systemically unwell needs prompt local assessment; severe acute illness requires emergency care. Do not assume every postoperative difficulty is ordinary stiffness.
