I am in a similar place to you. I have less function and more pain than knee #1. I guess they are all different. My surgeon says that the implant is great and that difference in pain is just soft tissue healing. My surgeon doesn’t track pain after 2 months and my internist put me on Gabupentin . That has helped. I continue to walk and do PT at the gym every other day. The days of my gym workouts, I have difficulty sleeping due to pain. I don’t know if I am doing the right thing. I ice a lot and an still taking Tramdol. Life was better with oxycodone, but that’s no longer available to me. When walking, I focus on form. In the gym, I do light weights and focus on form. Here’s hoping we are both well soon.
