In one study, Campbell et al. (2010) transferred the main trunk of obturator nerve to entire femoral nerve in a retroperitoneal schwannoma. Although the patient has regained 4/5 muscle strength in knee extension and almost normal gait, loss of adductor muscle function occurred [13]. Since the cooptation was performed on the entire femoral nerve, including the sensory branch, some motor fiber might have been lost. In our case study, adductor function preserved. We chosed the anterior obturator nerve as the donor nerve in order to preserve the potential adductor muscle function, that contribute to thigh adduction such as inferior fibers of gluteus Maximus (inferior gluteal nerve), quadratus femoris (sacral plexus) in addition to those served exclusively by the obturator nerve [10]. So that sacrificing anterior branch of obturator nerve (that innervates gracile and adductor longus muscles) should not lead to complete loss of adduction due to preserved adductor function of several other leg adductors.
