A Study on the Hard Wearing UV Treated Photopolymer Printing Plate for Articular Replacement/Arthroplasty (Biomedical)

Nowadays the usage of polymer on articular replacement (arthropasty) is common because of their known usage in orthopedic surgery and biocompatibility. The polymeric material such as polyethylene and polyacetal are common materials used in surgical repair of joint due to the arthritic or dysfunctional joint surface. The surgical repair is done by replacing the damage part with something better or remodeling or realigning the joint by osteotomy procedures. In this case, for both hip and knee replacement, chrome-cobalt and polymer are commonly used. According to Jennifer Brown, the cost for knee replacement is approximate to USD$15,000 per procedure with the estimation of total knee replacement is 600,000 annually in United States. Currently, the aggregate of annual cost for total knee replacement is about USD$9 billion. The usage of chrome-cobalt and polymer is very common and save but the cost is very expensive. The other disadvantage is it usually last only for 10 years for hip and knee replacement.
