Aching pain at and below the patella. Difficulty straightening the
knee.
Pain is most servere when putting weight or pressure on it.
Pain can be felt when climbing up the stairs, jumping, running and standing for prolonged periods. In addition, pain can be felt behind the knee cap. I've had blows to the front and side of the knees before when playing soccer.
The Orthopaedic diagnosed me with having Patella Tendonosis. However, I'm seriously starting to doubt the diagnosis.
