84 y/o female who is 4 weeks post-op after bilateral staged (2 weeks) total knee replacements. Doing well at home with daughter, but has a long road ahead with gait training, strengthening, and pain management.
Best wishes to my grandma and the over 500000 other people getting knee replacements this year.
Always evolve,
Mike

Mike, Saw grandma yesterday – seems to be doing fine – lots of spunk! Walked (with walker) out to the middle of the cul-de-sak to greet a neighbor. If we could just find a way to get her (safely) through that 22 inch wide bathroom door… Uncle Richard
