Knee flexion is up to 108 degrees, enough to do some range of motion cycling (not aerobic) on my exercise bike. A few days ago at my two week visit, I was cleared for easy walking on flat, and obviously, non-technical terrain. So, my movement world has enlarged. Until I can drive - probably another three weeks - my go to place will be laps on our gravel drive way. (Supplemented by some hiking on the roller ski track at MVH, when I can get Selden to do drop-offs.)
