Document Summary
Cause: direct blow to the anterior aspect of the knee such as falling onto a flexed knee during activity: chondromalaci a patella (softening and breakdown of the tissue cartilage on the underside of the knee cap, suprapatellar, Dull aching pain felt behind, below and on the sides of the patella. Skin redness and inflammation at the site of the bursa. Abnormal knee cap positioning, tightness or weakness of the muscles associated with the knee, excess activity involving the knee, and excess pronation of the feet. Repeated pressure/mechanical loading on the knee e. g. from activities involving prolonged kneeling, or repetitive microtrauma. Special tests, such as the posterior drawer or sag sign, will help identify instability; the dial test is helpful for determining isolated pcl or multiligament involvement. Stress test is a symptom-reproducing test which aggravates symptoms and causes some discomfort. Arthroscopy is an invasive procedure and may be associated with pain/skin damage.
