I am a 72 year old obsessed tournament racquetball player. I have been playing a minimum of four times per week since 1972. Both knees have been bone on bone for around 20 years. Dr. Palumbo replaced one in April and the other in November. In both cases, I was back on the court in eight weeks. Several of my racquetball buddies that have had the same knee replacement with different surgeons did not have as good a result as myself.
