Muscle group of the anterior thigh that extends the leg; composed of recta femoris, vastus intermedius, vastus lateralis, and vastus medialis.
Situated at the anterior region of each thigh, there exists a group of four muscles known as the quadriceps. These muscular structures play a pivotal role in extending the knee joint and are actively engaged with every step an individual takes.
Situated at the front of the thigh, the quadriceps muscle is a sizable muscle comprising four distinct components. Its primary function involves extending the knee joint to achieve straightening.
The prevalent affliction affecting the quadriceps is hematoma formation, which arises from a direct impact. Bruising might manifest several days afterward. In uncommon instances, bone tissue develops within the hematoma, leading to limitations in mobility.
Rapid elongation of the leg can result in the muscle fibers tearing, particularly in individuals of middle-aged or advanced age. A disruption of the quadriceps tendon can stem from a direct impact on the leg or from stumbling. Conditions affecting the knee that induce discomfort or swelling and hinder complete leg extension trigger a process of muscular atrophy within 48 hours. This phenomenon can cause a sensation of instability in the knee when weight is borne by the impacted leg. Specific exercises aimed at fortifying the quadriceps are employed in the treatment of select knee ailments.
