The Dreaded Runner’s Knee
Dr Jennell Kopp, Colfax Marathon Medical Director
That feeling when you notice a vague soreness in the front of your knee that you can’t pinpoint. Then you start to notice more localized pain with going up the stairs or coming down a hill. The pain sometimes gets more severe around the top of your kneecap (patella) or along the rubber band that attaches the kneecap to your leg (patellar tendon.). Then it progresses to a sharp pain with bending or a crunchy sound in your knee (crepitus.) Sometimes, you may even have pain with sleeping or sitting in chair for too long.
