Sitting in the sports medicine clinic’s waiting room, I poked at my knee and winced, hoping that the doctor would be able to fix my troubled joints so I could run my first road race the following month. Half an hour later, I had my answer: my biomechanics were off, I suffered from the common patella-femoral syndrome, but with physiotherapy and diligence, I’d still be able to run. An acceptable prognosis, so I smiled. I liked the doctor; how she paid attention to my grimaces as she prodded my leg, and explained all the anatomical terms to me as she discussed my diagnosis with the observing resident. And then it happened.
