It is commonly discussed in knee care because the quadriceps helps control the kneecap and stabilize the knee. Clinicians use the term when documenting weakness after injury, surgery, or prolonged inactivity. Patients often notice it as a smaller thigh, difficulty with stairs, or the knee feeling less steady."}
