Can Roy's knee cartilage be re-grown?
The following quotes are from Olympic swimmer, Dara Torres. Her knee problem was different than Roy's but, nonetheless, she discusses THE GROWING of cartilage. My (admittedly selfish) best scenario for this has Roy receiving some treatment along these lines, which would take a few years – just in time for Roy to be eligible as a Blazer, again. Follow this link to learn a lot about this and two other cartilage procedures from medpagetoday:

"When I realized how bad my knee injury was, the biggest thing I was scared about was that I wouldn’t be able to take care of my daughter and to possibly continue to swim. I didn’t know if I would have to have a total knee replacement at my age, which was only 43, and I didn’t know if I would be able to walk again or run after my daughter … I was basically limping."

Torres underwent the procedure, called autologous chondrocyte implantation in the fall of 2009. She is pleased with the results [one year later]: "I notice big differences. I’m not limping anymore and I have a lot more flexibility. I have had about three MRIs since then and they’ve shown the progression of cartilage cells growing on my kneecap, you could see a nice thick layer of cartilage growing."
