Methods of femoral nerve damage recovery include medication (B vitamins, nerve growth factor, etc.), surgery (nerve anastomosis, etc.), physical therapy (ultrashort wave, infrared radiation, etc.), and rehabilitation training. 1. Drug treatment: B vitamins, vitamin B12, nerve growth factor and other neurotrophic drugs can treat nerve injury and neuritis. 2. Surgical treatment: nerve anastomosis is suitable for nerve injury with neat severed end and no defect. Nerve release surgery is suitable for patients with blunt nerve contusion and unsatisfactory functional recovery after nerve suture or free nerve grafting. 3. Physiotherapy: Ultrashort wave therapy can dilate blood vessels, strengthen blood circulation of nerves and surrounding tissues, and promote local tissue metabolism; medium and low frequency electrotherapy can stimulate muscles and prevent muscle atrophy; infrared therapy, through the thermal effect of infrared irradiation, can improve local blood circulation of the damaged nerves, accelerate the metabolism of the tissues, and promote the absorption of the oedema of the damaged parts. 4. Rehabilitation training: early quadriceps functional exercise to maintain muscle tone and elasticity, to avoid too rapid muscle atrophy and fibrosis while waiting for nerve recovery. In case of femoral nerve damage, it is recommended to seek medical treatment as soon as possible for standardized treatment. Patients who have received surgical treatment should pay attention to follow the doctor’s instructions for regular review of electromyography to clarify whether the femoral nerve has recovered or not; and consult the doctor promptly if there is any discomfort during the rehabilitation training.
