3 years later, knees made for dancing

¶Going down steep steps can be difficult and may require a sideways, one-foot approach. A normal knee bends at an angle of about 145 degrees, but replaced knees often achieve only 120 degrees, if that. Sitting on the floor cross-legged may be impossible.

¶Despite the passage of time and many months of physical therapy, there can be residual discomfort. I “feel” my knees on every rotation of the bike pedals, though the sensation is not what I would call pain and not enough to stop me from riding.
