I had my last checkup (4 months postop) with the ortho surgeon today for my knee surgeries. He said that everything looked good.* My range of motion is normal. There is no swelling. The bit of pain I've been experiencing is normal healing from the patellar debridement. That could take as long as year to heal. He also said that once you get tendonosis in the knee, it's managed as a chronic condition. I may have a little pain for the rest of my life. Ice it and take anti-inflammatories as needed.
I really want to see how my knee holds up to 4+ hour rides once the weather is better. I had planned to do 1-2 endurance mountain bike races this year, but I'll have to see. I know it's fine for 3 hour rides on back to back days with just a little soreness from the riding I did over the holidays. Once I took 48 hours easy after 3 days of back to back riding, the pain went away.
*I had bruises, cuts, and a bandage on my legs from a little crash on my mountain bike on New Year's Day. He wondered what I'd been doing. He said if I was back to doing 20+ mile mountain bike rides, I am fine!
