Introduction

Muscles are attached to the bones by cord-like fibrous tissues called tendons. Quadriceps muscles are attached to the tibia or the shin bone through the patellar tendon. The upper portion of the patellar tendon is attached to the lower portion of the knee cap, and the lower part of the tendon is attached to the tibial tubercle. The quadriceps muscles are attached by the quadriceps tendon to the upper portion of the kneecap. The quadriceps muscles and tendon, along with the patellar tendon, help during walking, running, flexing, and extending the knee.
