Experienced Arthritics Here?

Hubby had torn miniscus surgery on both knees. Might as well not have bothered. Then, 2 yrs ago he had one knee repalced. Two months ago he had the other replced. Recovery from both has been very good. The difference has been night-and-day for him. Knee #2 is still sensitive to cold weather and a tad unstable, but it is improving daily. He is out riding his scooter as we speak.
