I'm about 16 months out from TKA left knee. I experienced a great deal of scar tissue buildup and after very intense PT including any and all machines to improve my ROM. My extension is about 5 degrees and flexion is about 105. I can manage my life, but I still limp a bit and I'm not satisfied with my result. My surgeon states that because of my very tight knee joint (scar tissue mass and too thick plastic liner) he wants to swap out the liner/spacer with a thinner plastic liner (2-3 mm smaller). I would appreciate any knowledge and/or experiences with this procedure. All other components look terrific and in alignment. Should I agree to this revision or just suck it up and be grateful for a minor limp.
