Ouch. I only had cracked patellas (yes, I've managed to crack them both). Thankfully, an imobilizer brace was all I needed, and they have both healed. The left was the more recent one, and I'm coming up on the tail end of my "no squats" instruction from my surgeon. I'm sure the cast is most uncomfortable and inconvenient. Definitely take it easy for a few months and allow it to heal well. Your surgeon will guide you through the reactivation process with a reasonable amount of caution.
