I had mine rebuilt after shattering the back of the patella. The surgeon (who had never seen an injury like mine in 30 years of surgery) pulled pieces of my broken patella out of three little holes that he made in my knee joint. He then sewed up all the holes that the pieces of bone had left in the cartilage.
I still have a kneecap. I can still cycle, run and even ski.

I can't play contact sports.
