Abstract:
Prosthesis revision and service life after artificial joint replacement is highly correlated with the biocompatible responses among prosthesis per se, host, and manipulating technique. Artificial prosthesis consists of two parts: metal part and rigid plastic components. Many metals such as stainless steel, cobalt-chrome-molybdenum alloy and titanium alloy can be used as prosthesis materials. The plastic materials mainly include wear-resisting polythene, plastic bone cement that is used to embed the prosthesis into osseous substance. Host defines as the patients with various joint injury, mainly the elderly. Anesthesia is a key step in replacement. Artificial joint replacement is performed in patients under anesthesia. Different anesthesia methods bring variable influences on biocompatibility after surgery. In addition, complications of anesthesia may aggravate tissue lesions around operation sites in the early stage after replacement, leading to joint loosening or inadequate joint range of motion. Appropriate anesthesia, modified artificial joint design and joint replacement technique can prolong the serve life of artificial joint.
