A team of researchers at the University of Southampton has developed a new method to fit joint replacements with longer lifespan.
The project called MXL will enable surgeons to increase the lifespan of the joint replacements. The method is based on computational modeling that defined the mechanics of an artificial joint in order to make sure that the surgery is successful and the prosthetic joints have a longer lifespan.
"Joint replacement surgery substitutes worn-out joint tissues with artificial components. These artificial components will also fail eventually, some after only a few years, with nearly ten per cent of all joint replacement operations in the EU each year taking place to replace prosthetics that have worn out," Professor Markus Heller, leader of the MXL project, says.
"These 'revisions' of joint replacement surgery are complex, require a longer rehabilitation and also come at a substantial cost, with a hip revision estimated to cost €80,000($104,488)," he adds.
Currently, the surgeons depend on their experience in order to get the best results out of a joint replacement surgery. But the new ICT system created by the MXL project will allow a cost effective development of a robust prosthesis design. This will support the decision making in the surgery and provide a safer and optimal outcome for the joint surgery.
According to Professor Heller, the new project offers a 3D musculoskeletal model that has data on the difference in bone shape and tissue density that helps in advanced biomechanical assessment of the joint reconstruction. This software will permit automated placing of implants and permit the surgeons to alter and modify the size of the implant according to patient needs.
The project was funded by European Commission's Seventh Framework Programme.
