Manipulation under anrthesia did work for me had twice still can not bend or straighten left leg had total knee repla cement?

Mechanical problem: Stiffness after (tkr) is a frustrating complication that has many possible causes.Component malposition, malrotation, or overstuffing of the joint has a greater chance of regaining motion than arthrofibrosis without a clear cause.Although surgical treatment with open arthrolysis, isolated component, or complete revision can be used to improve tkr motion, results have been variable

Talk to MD: If you still cannot bend your knee after two manipulations under anesthesia you need to talk to your surgeon.
