There are several types of joint replacement as follows: 1) hip replacement, knee replacement, etc. according to their body parts; 2) ceramic joint replacement, polyethylene joint replacement, ceramic to polyethylene, ceramic to ceramic, etc. according to their materials; 3) classification according to the amount of bone carried out during replacement, such as the common total knee surface replacement, unicondylar replacement, patellar replacement, in addition to the hip joint can also be a total hip replacement and hemi-hip replacement, etc. As an organ replacement, artificial joints are bound to suffer from wear and tear and failure, but modern artificial joint prostheses have been able to achieve good long-term survival rates. The National Institutes of Health (NHS) in the UK has proposed a standard for artificial joint replacement, which is a ten-year success rate of at least 90%, called the NICE standard. And in clinical practice, there has been a lot of data showing that through good surgical technique, selection of suitable artificial joint prosthesis, and with full cooperation of patients, the 20-year excellent rate of artificial joint replacement, especially knee and hip replacement, can reach more than 90%.
