Imported hip joints have the promise of 30 years of use. The average service life of hip joints, whether imported or domestic, is 10-20 years. In addition to the material, it is also related to the patient’s bone strength, muscle condition and other factors. If the patient’s muscle strength is weak and he does not insist on training the strength of the muscles around the hip joint after surgery, the stability of the hip joint becomes poor, which easily leads to a shortened service life of the hip joint. If you insist on muscle exercise to enhance the stability of the hip joint, the service life of the artificial hip joint will be further extended. In addition, the degree of osteoporosis of the patient also determines the service life of the hip joint. If the osteoporosis is more serious, the contact surface between the artificial joint and the bone will be loosened, which will lead to a shorter life span. If a balanced diet, appropriate physical activity and enhanced bone density can make the artificial hip joint service life extended accordingly, and with multiple efforts, the service life of the imported hip joint is expected to reach 30 years.
