Purpose: To investigate morphological changes in the infrapatellar fat pad (IPFP) during active knee extension using ultrasonography. Methods: IPFP deformity from 30 ∘ flexion to full was recorded thickness and patellar tendon-tibial angle were evaluated on 26 healthy knees first session nine second session. Intra-rater inter-rate reliability coefficient of variation (CV) intraclass correlation (ICC) types (1, 3) (2, 3), respectively. Absolute assessed standard error measurement (SEM). Changes analyzed paired [Formula: see text]-test. Results: At each angle, ICC text] for (CV text]). Compared flexion, increased significantly 33.3 38.9 ([Formula: The 4.4[Formula: text]mm 5.3[Formula: with text]), without overlap 95% CI SEM. For inter-rater reliability, variable Conclusions: Increased indicates anterior interval. Ultrasonography may help evaluate estimate scarring.
