The relationship between additional heads of the quadriceps femoris, the vasti muscles, and the patellar ligament.

ABSTRACT:

Introduction

The quadriceps femoris consists of four muscles: the rectus femoris, vastus medialis, vastus intermedius, and vastus lateralis. However, the effect of additional quadriceps femoris heads on the vasti muscles and patellar ligaments is unknown. The aims of the present study are to determine the relationship between additional quadriceps femoris heads and the vasti muscles and patellar ligaments and to review the morphology of the vastus lateralis, vastus medialis, and vastus intermedius.

Materials and methods

One hundred and six lower limbs (34 male and 19 female cadavers) fixed in 10% formalin were examined.

Results

On all lower extremities, the vastus lateralis consisted of superficial, intermediate, and deep layers. The vastus medialis, on the other hand
