Running Injuries: The Infrapatellar Fat Pad and Plica Injuries.

When considering knee pain in runners, clinicians differentiate sources of symptoms and determine their cause. Knee problems arise when a runner increases the amount/frequency of the loading through the lower limb. The way the loading is distributed through the knee determines which tissues are abnormally loaded. Knee problems cannot be considered in isolation, requiring a thorough investigation of static and dynamic lower limb mechanics, and footwear and surfaces. This article examines potential sources of knee pain and explores the role of the infrapatellar fat pad and synovial plica in the mechanics of the knee and its involvement in knee symptoms.

BACKGROUND: Knee osteoarthritis is one of the most debilitating diseases associated with aging, and is estimated to affect 9% of men and 18% of women over 65years of age. Knee osteoarthritis affects the condylar surfaces of the joint and if left untreated generally leads to the slow and painful degeneration of the joint and surrounding structures. With few non-invasive treatment options for osteoarthritis patients, this study investigated the effect of therapeutic taping on knee pain in combination with spatiotemporal, kinematic, kinetic and muscle activation measures.
