Advance in Hoffa's Disease and Substance P Positive Nerve Fibers (review) / 中国康复理论与实践

ABSTRACT

Hoffa's disease is the clinical condition characterized by anterior knee joint pain secondary to inflammation and/or impinge-ment of the infrapatellar fat pad. The substance P positive nerve fibers rich in the infrapatellar fat pad were stimulated by the noxious stimu-li, which may associated with the pain of Hoffa's disease. The relationship between Hoffa's disease and substance P positive nerve fibers in the infrapatellar fat pad was reviewed in this paper.
