Låter ju faktiskt precis som Runner´s knee (inte samma som Löparknä tydligen)

Runners Knee is a condition characterized by pain behind or around the kneecap. Poor kneecap tracking is believed to be the main cause this condition. The kneecap (patella) slides over a groove on the thighbone (femur) as your knee bends and straightens. If, for example, the front thigh muscles (quadriceps) are weak or imbalanced, the resulting muscle imbalance can pull the kneecap to the left or right of the groove, causing pressure, friction, and irritation to the cartilage on the undersurface of the kneecap when the knee is in motion.
Overuse/overload of the quadriceps - especially running, going up and down stairs - can cause this condition to flare up, as can poor exercise techniques, e.g. a poorly fitting bicycle, improper footwear etc.
Causes of Knee Maltracking
Muscle imbalances / weakness or inflexibility in the muscles that support the knee, and mechanical errors can cause poor knee tracking. There may be multiple factors involved.
