Final answer:

Anterior thigh pain is often associated with impairment of the femoral nerve, which innervates the anterior compartment including muscles responsible for extending the knee.

Step-by-step explanation:

When a patient presents with anterior thigh pain, the nerve that could be suspected of being impaired is the femoral nerve. This nerve innervates the anterior compartment of the thigh, which includes the quadriceps femoris group responsible for extending the knee and aiding in raising the knee. The femoral nerve emerges from the lumbar plexus, travels through the pelvis, and enters the thigh where it provides motor and sensory function to the anterior compartment. If the femoral nerve is damaged or compressed, it might lead to pain, weakness, or sensory changes in the regions it supplies.

The anterior compartment of the thigh is made up of muscles like the rectus femoris, the vastus lateralis, vastus medius, and vastus intermedius. Damage to the femoral nerve can impede these muscles' ability to extend the leg and flex the thigh. This should not be confused with sciatica, a condition associated with the sciatic nerve, which originates from the sacral plexus and affects the posterior thigh, rather than the anterior.
