@ssbionicknee, I was not aware you could be diagnosed that quickly with frozen shoulder. I had my torn rotator fixed on June 15th, 2018. I was not allowed to even move it or begin any PT until that 6 week mark, and my mobility was extremely limited and very painful. I just had an appointment a few weeks ago (around the 16 week mark) and was told mobility is often not fully regained until closer to a full year or slightly beyond. My progress in PT has been so slow that it is beyond frustrating. Like you, I had a knee replaced, and even though that recovery was hard for me (had to have two manipulations due to aggressive scar tissue), you are right that you at least get to start PT right away.

I am closer to the 20 week mark now for my surgery, and I can say I have finally started to make some big gains with my shoulder. I am finally back to lifting some weights and doing more aggressive exercises. The mobility is still not near 100% and it is still really stiff, I am making progress.

I only bring this up, because progress when i started PT at that 6 week mark was so slow and for weeks it felt like I was getting nowhere. I still have pain at 20 weeks, but it is not near as bad. I still am not sleeping uninterrupted because it is just impossible to get in the position that I preferred to sleep in before surgery.

@ssbionicknee, may I ask how they diagnose frozen shoulder? Did they take MRIs? Were you in an immobilizing brace for 6 weeks? My ROM after I came out of my immobilizer was next to zero as well, but they said that it was normal and that shoulders are the most difficult joint to rehab.
