Update had a Dr appointment today …. Been in therapy about 12 weeks measure was moving somewhat….. had to take two visits off went down 5 degrees… Dr told me today I am at flexion 70 extension 10 before revision two years ago I was 65 flexion close to same extension….dr explained to me that no surgery can fix this he went down two sizes and still my knee went back to where it wanted to be … he said simply the tissue around the knee is where it wants to be … he said scar tissue removal I go right back , if he removed the knee and but a hinge it would go back to this ….. it is bad luck but it happens …. But I am happy he explained and showed me the pictures …. I felt my body did not like the knee now I know it doesn’t ….. all I can do is exercise to keep any flexion , and pain away…..I respect him he could have used me as a cash cow but I appreciate his honesty….,good luck to everyone my surgery journey is over ….. I hope everyone finds there Dr and there answers
