| dc.description.abstract | Among all joints in human bodies, the knee joint bears the biggest load. With the development of medical science in recent years, the average human life-span has been lengthened year by year. Nevertheless, more and more people are troubled by osteoarthritis. Nowadays around three hundred and twenty thousand people in Taiwan are suffering from the pain of knee joints. Serious pain can be caused during walking and going upstairs and downstairs. Furthermore, it is very inconvenient for they are unable to use squat toilet. If patients receive the operation of knee arthroplasty, the pain would be lightened or even totally eliminated. In addition, the function, movement and the problem of deformation of joints can be improved.
Minimally invasive surgery is definitely an important modern medical development tendency. According to the statistics, in one year, nearly ten thousand patients in Taiwan need the surgery of knee arthroplasty. This research aims to: 1. develop a brand-new smaller knee joint; therefore, the patient with a small area cartilage damage can have choice according the symptoms; 2. design custom-made implants and its surgical instruments: custom-made surgical instruments make the operation procedure comparatively simple; the surface of custom-made implants will fit the curved surfaces of patients’ joints, reducing the stress-concentration caused by the uneven surfaces of skeletons after the operation; 3. build and construct the true knee joint simulation of dynamic sport and movement and the analysis platform of force, hoping to improve the design of the knee joint implant.
