Diabetic femoral head replacement is usually related to physiological factors such as lack of physical strength or fatigue, and may also be related to pathologic factors such as hypokalemia, postoperative complications, etc. General treatment, medication, and functional training can be adopted to alleviate the symptoms in conjunction with the cause of the disease. 1. Physiological factors: After surgery, due to prolonged bed rest and lack of physical strength, or fatigue caused by the recent increase in the amount of activity and other factors, the phenomenon of walking without energy can occur, which is a normal physiological phenomenon, and will be relieved by itself in 3~5 days after adaptation, and does not require any special treatment, and should be according to the physical strength of the appropriate amount of activity. 2. Hypokalemia: If diabetic patients have poor blood sugar control or electrolyte disorders during the perioperative period, it may cause hypokalemia, which may lead to weakness and weakness of the body, and walking on the ground may show the symptom of weak legs and lack of strength. Patients should follow the doctor’s instructions to control the blood glucose level and use reasonable medication to correct electrolyte disorders. 3. Post-operative complications: If the nerve is damaged during the operation, or there are complications such as muscle atrophy, the phenomenon of weak walking may occur. Under the guidance of the doctor, muscle and joint training should be carried out to promote the recovery of muscles and nerves, and methylcobalamin and other nerve-nourishing drugs can be chosen according to the doctor’s instructions. There may be other reasons for diabetic patients to lose strength after femoral head replacement, so it is recommended that patients consult their doctors in time to clarify the reasons before targeted treatment.
