Manipulation under anaesthesia (MUA) is a procedure to improve the range of movement of a stiff joint, performed while the patient is anaesthetised to relax all the muscles.


How MUA is performed

The patient is anaesthetised and a femoral block may be performed to offer pain relief even after the patient awakes. During the anaesthetic, the surgeon bends and straightens the knee a number of times to break the adhesions. When the knee is able to bend to about 120 degrees it is held flexed for a minute or so. Then the bending and straightening is performed again. After the procedure, motion may be continued with a CPM machine and adequate pain relief.
