Your doctor will likely ask when you noticed your knee pain, how it has been feeling since the pain began and if you've injured your knee before. He or she also may ask about any other conditions you have, such as diabetes and allergies, and if you are currently taking any medications.
Your doctor will assess the injury by feeling the knee area. Because the kneecap is easily accessible, he or she can quickly test for pain and tenderness by moving your kneecap and check how well it tracks as you flex and extend your leg. After this brief exam, your doctor most likely will be able to tell whether your discomfort is due to patellofemoral pain syndrome or another knee problem.
Should your doctor require a closer look, the following tests may be conducted:
Patellofemoral pain syndrome may indicate that the protective cartilage under your kneecap is wearing down, which can eventually lead to bone loss and arthritis.
