Figure 4From: Diagnosis of ACL and meniscal injuries: MR imaging of knee flexion versus extension compared to arthroscopy Complete ACL rupture in a 50-year old patient. T2-weighted TSE FS sagittal image (2900/90) obtained at extension (A), 30° (B), and 55° (C) of knee flexion better demonstrates the complete disruption and retraction of the torn ACL fibers than MR images taken at knee extension (A). At knee extension an accurate differentiation between a partial and complete ACL rupture is not possible.Back to article page
