Answer:

Dear ANNETTE,

Thank you very much for your question.

Knee pain is caused by trauma, misalignment, and degeneration as well as by conditions like arthritis.

The most common knee disorder is generally known as patellofemoral syndrome.

The majority of minor cases of knee pain can be treated at home with rest and ice but more serious injuries do require surgical care.

One form of patellofemoral syndrome involves a tissue-related problem that creates pressure and irritation in the knee between the patella and the trochlea (patellar compression syndrome), which causes pain.

The second major class of knee disorder involves a tear, slippage, or dislocation that impairs the structural ability of the knee to balance the leg (patellofemoral instability syndrome). Patellofemoral instability syndrome may cause either pain, a sense of poor balance, or both.

Age also contributes to disorders of the knee. Particularly in older people, knee pain frequently arises due to osteoarthritis. In addition, weakening of tissues around the knee may contribute to the problem. Patellofemoral instability may relate to hip abnormalities or to tightness of surrounding ligaments.
