In general, an inciting trauma, surgery, or infection results in a healing response which includes the migration of inflammatory cells and the proliferation of fibroblasts followed by the release of cytokines, growth factors, and reactive oxygen and nitrogen species.1 Failure to terminate the healing response normally results in persistent inflammation of the synovial tissue with increased inflammatory cytokines and certain growth factors that trigger tissue fibrosis via the transformation of fibroblasts.1 Fibroblast proliferation results in the accumulation of increased extracellular matrix which impairs blood flow and results in local hypoxia. The infrapatellar fat pad is richly innervated and is an important pain generator in the knee.14 Surgical and traumatic insults to the infrapatellar fat pad can induce fibrosis and metaplasia resulting in pain (September 2008 Web Clinic Patellar Fat Pad Abnormalities).13,14.
