Anyone had a polyethylene liner exchange for knee stiffness post TKA?

Approximately 16 months ago I had a left total knee replacement(TKA). I was a very motivated rehab patient (80 visits to PT and hours on many types of machines). Today I still limp (5 degrees extension and 105 degrees flexion). I can probably live with this, but I'm not particularly happy. My ROM should be better (no limp). My knee joint is without infection and well aligned and very stable. My surgeon confirms this and states that my joint is "tight" with no instability. He recommends a single component open surgery polyethylene liner exchange. He believes my implanted liner component is 2-3 mm too thick and has reduced my ROM arc. He believes a thinner liner will enable me to improve my ROM. Does anyone have any experience with this type problem and a recommendation or solution. My research has been unsuccessful in finding much information for my issue. Thank you very much!
