There is actually an association for the study of the population of patients experiencing arthrofibrosis post surgery. It is believed that prior surgeries to the joint predispose joint to form excessive scar tissue in subsequent surgeries. ( I did have two previous surgeries on the TKA knee). Also, there are some orthopedic surgeons who believe that a more “gentle” approach to physical therapy could benefit patients with a history of excessive scarring in joint. I believe that the use of continuous passive motion machines should be brought back into use for the arthrofibrosis patients post remedial surgeries.
I guess barring any medical breakthroughs in treating this problem, we, the unlucky, just have to continue our feeble and painful attempts to maintain and/or regain better flexion😕
