Abstract

This anatomical study examined: i. whether the VMO and VML are two distinct muscles, ii. muscle fiber angles of the VMO and VML, iii. VMO and VML muscle fiber lengths, iv. VMO nerve supply, v. VMO insertion onto the patella. The length of the VML, VMO superior, and VMO inferior sections were calculated as a percentage of total VM length. Fiber angle data for VML, VMO superior, and VMO inferior were determined according to the femoral axis. It was concluded that the distal portion of the VMO is not distinctly separated from the proximal portion of the VM and VML. There was not a distinct fascial plane between the two sections. Each head of the VM was innervated by different branches of the femoral nerve. Most of the VM inserts into the quadriceps tendon with only a small portion inserting directly into the patella.
