Diagnostic Validity Ofclinical Tests for Infrapatellar Fat Pad Impingement Syndrome

The clinical evaluation specific to Infrapatellar fat pad is based on a series of five standardized clinical tests, extensively described in the specialized literature: provoked palpation of the fat pad, provoked passive extension, Hoffa's test, gliding test, and provoked passive flexion. These tests are performed in a randomized order to limit sequence bias. A test is considered positive if it reproduces the patient's typical anterior knee pain with an intensity greater than 2/10 on the numerical pain scale. Although widely used, these tests have not yet undergone rigorous methodological validation, which this study specifically aims to address.
