Methods and Materials
Methods and materials:
- A 16 year male athlete developed acute severe pain and swelling along the medial and posteromedial aspect of the left knee immediately after performing a standing broad jump.
- The patient was examined by a sports surgeon who suspected acute ACL and MCL partial tear/sprain,
and a medial meniscal tear.
- Radiographs on the (L) knee were performed in two orthogonal views.
- Non-enhanced MRI of left knee was performed with following sequences.
(1)Coronal T1W
(2) Coronal Proton Density (PD)Fat Saturated (FS)
(3)Sagittal PD thin slice 1.5 mm
(4)Sagittal GRE T2*
(5)Axial PD
(6)Sagittal PD for anterior cruciate ligament
(7)Axial T2FS
(8)Sagittal T2FS
(9)3D- Double Echo Steady State (DESS)-T2W (0.6 mm)
- Published literature on avulsion fracture of the medial head of the gastrocnemius was reviewed.
- Published literature of the biomechanics of the standing broad jump was also reviewed.
