Motor branches to the rectus femoris arise from the femoral nerve in the femoral triangle, entering the muscle on its deep surface at the proximal and middle muscle belly. Rectus femoris has dual innervation from multiple femoral nerve branches, providing some redundancy.
The nerve to rectus femoris is assessed in femoral nerve injury workup — it is the most proximal quadriceps motor branch and its denervation indicates a proximal femoral nerve lesion. Selective rectus femoris botulinum injection targets this nerve for spastic stiff knee gait in cerebral palsy, reducing the excessive hip flexion momentum during gait. EMG of the rectus femoris belly distinguishes femoral from L3/L4 root lesions.
Botulinum toxin injection into rectus femoris targeting the femoral nerve motor branch for stiff knee gait, reducing the velocity-dependent stretch reflex in the knee extensor and improving knee flexion during swing phase.
