Hi I had a mua with my first tkr I was at 65 flexion could not get anywhere with therapy I was 6 weeks out of surgery….. for me made it worse … two or three days after procedure therapy told me stay home I was so swollen and lost flexion….. after that went for second opinion found out my tkr was 2-3 sizes too big with year went got another tkr now I am at 105 almost full extension ….. I suffer from scar tissue having to have tkr twice so I do mfr, graston and a lot of exercise…. Always work in progress lol but so much happier now ….. but don’t give up …. Be prepared mua is tuff may have set back at first but hopefully after swelling passes you will have move flexion …..good luck
