What percent of people get manipulations after tkr?

Maybe 1-3 % or so.: Its getting less and less frequently done. I may have done maybe twice in the last 17 yrs or so, but saw it done during my training 10-12 times in about 2 years. You had a tib plateau fx, so you have had at least 3 surgeries (fixation of the fx, removal of hardware & tkr), so you have had plenty of scar tissue, to require manipulations.
