Warning: thread hijack . . . I ruptured one of mine many years ago. Went for the surgery. Hiking was the best rehab: mild stress plus flexion. That leg was smaller for years, even doing one-legged pedaling. It took maybe 1 year until I felt fine again, 10 years to get everything back in balance. I was riding almost as soon as the cast was off though, because of the low stress. The specialist told me I'd never climb or run again. As usual, he was full of ****.
