After the artificial joint replacement surgery, patients need to pay attention to more protection and care in the long life ahead so as to ensure the service life of the artificial joint. Precautions after Artificial Joint Replacement Surgery 1. Reduce weight: Most of the force borne by the hip and knee joints is the body’s gravity, so reducing weight will reduce the pressure on the joints. After the operation, we should arrange the diet reasonably and keep the weight within the normal range to reduce the wear and tear on the joints. 2. Maintain normal limb alignment and gait: Normal limb alignment and gait can make the joint surfaces maintain sufficient contact area and uniform force, so that the force will not be too concentrated in certain areas, which will aggravate the wear and tear. So when standing, must ensure that the leg straight, walk with a big step, can not curl the leg to walk. 3, enhance muscle strength: good muscle power can not only make patients move freely, enhance motor coordination and posture reflex sensitivity, but also can reduce the joints to a certain extent, usually adhere to the exercise of the affected limb muscle power. 4, avoid a large number of difficult activities: joint replacement surgery patients, should reduce the amount of activity, especially the elderly patients, usually 2-3 months after the joint replacement can not need to walk without crutches, you can engage in most of the daily activities, you can walk, cycling, dancing, swimming. You can also practice qigong and tai chi, and avoid walking, standing and squatting for long periods of time. In addition, climbing mountains, stairs and running are harmful to the artificial joints, so it is recommended not to do them or to do them less often. You can carry some heavy things, but carrying too heavy things, especially when going up and down the stairs or walking on the ramp, it is not appropriate. 5. Preventing osteoporosis: As I said earlier, loose bone is not conducive to the fixation of the prosthesis, and the supporting force is also weak, and the loosening and subsidence of the prosthesis will occur in the long term, so it is necessary to prevent and control osteoporosis from three aspects: diet, medication, and exercise, so as to prolong the life of the prosthesis. In conclusion, after joint replacement surgery, you need to pay attention to all aspects of the problem in order to maximize the life of the joint.
