Comments: Four years ago Dr. Alden replaced both of my knees, six weeks apart. The surgery and recovery were without complications all the more impressive as I am not a terribly fit 60+ lady! The scars have faded tremendously and are very thin. But best of all I have no pain and have fully restored movement in bending and straightening. Knees no longer are the boss of my daily activities. Fully recommend Dr. Alden to help get your life back!
