Well had an Arthroscopy of my TKR on April 19, 4 months after the TKR due to excruitiang pain and stiffness. The surgeon found a large ball of scar tissue. I start back to PT today and cannot wait. My pain that I have is a normal post of pain and the stiffness is GBE and the locking up too. I feel like I am finally on my way to recovery. I use No assistive device and walk without a limp finally.
