Prosthetic knee joint maintenance

[Abstract]:
After total hip replacement or total knee replacement, most patients' pain will be significantly reduced, their function will be improved, and they can return to normal life, but the operation will not make the function of hip or knee better than before. Today we learn about the maintenance of prosthetic knee joint

After total hip replacement or total knee replacement, most patients' pain will be significantly reduced, their function will be improved, and they can return to normal life, but the operation will not make the function of hip or knee better than before. Today we learn about the maintenance of prosthetic knee joint

After prosthetic keen joint replacement, we need to develop good habits of life and activities to maintain the stability of the prosthetic knee joint. After the operation, cycling, walking, dancing, swimming, golf and other sports can be carried out, but vigorous sports such as running and dancing, long-distance walking, mountain climbing and other sports are not encouraged. High impact contact sports should be prohibited. Under normal condition, the artificial joint will produce a little wear. However, excessive movement and loading will accelerate the wear of prosthesis, which may lead to the loosening of prosthesis.

Once the prosthetic knee joint is infected or aseptic loose, it needs to be repaired. There are knee prostheses and surgical instruments specially designed for revision operation. Revision surgery is more complicated than the first operation, which may require bone grafting, replacement of joint prosthesis type or use of special prosthesis. After revision, most patients can get ideal results.

Reduce weight and wear

Most of the strength of the prosthetic knee joint comes from the weight. To reduce the weight and control the weight can reduce the wear of the artificial joint. After joint replacement, patients should reduce the amount of activity properly, and try to avoid walking too long, running and jumping violently, climbing mountains, frequently going up and down stairs, or improper weight-bearing. Swimming, water aerobics, cycling, dancing, golf and other sports activities are relatively less wear on the prosthesis. Usually can participate in general sports and work, not recommended to engage in heavy physical labor.  

Prevention and treatment of osteoporosis

 

Osteoporosis is not conducive to the fixation of the prosthetic knee joint, and the loosening and subsidence of the prosthetic knee joint may occur in a long time. Therefore, patients should actively prevent and treat osteoporosis from diet, medicine, sunshine and proper exercise.

Avoid infection and embolism

The infection should be prevented and treated before and after operation. Such as tonsillitis, caries, skin infection, tinea manus and pedis, and so on. This is because the bacteria infected in other parts of the body may transfer to the prosthetic knee joint, causing joint infection. There is still the possibility of joint infection in the later stage of the prosthetic knee joint. If the prosthesis is is taken out seriously, it is easy to lead to the complete failure of the artificial joint. Therefore, it is necessary to effectively prevent infection in all parts of the body. In case of infection, such as cold, pneumonia, furuncle, urinary tract infection, etc., it should be treated in time. In addition, deep vein embolism is also difficult for medical staff to control. Patients should take anticoagulants according to the doctor's orders and take active and moderate activities in the early stage after operation to reduce and avoid the occurrence of deep vein embolism.

Avoid damage

Follow the principle of "train muscles and protect joints" to enhance muscle strength. Good muscle strength can not only enable patients to move freely, enhance limb coordination and sensitivity, but also reduce joint stress to a certain extent. The impact of prosthetic knee may occur in cross legged sitting, low stool sitting or squatting, which may lead to the loosening or even dislocation of prosthetic knee. When the traumatic fracture occurs around the prosthetic knee joint, the fracture is not easy to heal, and it is easy to cause the prosthetic knee joint to loosen. Usually, pay more attention to avoid injury and fall.

Pay attention to follow-up

Just as the car needs to go to the 4S shop for regular maintenance, the patient must pay attention to the lifelong follow-up of the prosthetic knee joint. During reexamination, check the function of prosthesis, check whether there is osteoporosis in bone mineral density, understand the situation of functional exercise and recovery, so as to find out whether there is adverse tendency such as prosthetic knee joint loosening in the early stage. In case of any discomfort, communicate with the doctor and remove the hidden danger in time. Regular follow-up is conducive to early detection and treatment of problems, and to prolong the service life of the joint.
