Ke Huy Quan is an obese 54 year old male who had a total hip arthroplasty done. His pain symptoms returned 5 years post op as a result of osteolysis. The bone atrophy in the bone diaphysis (medullary canal) caused the aseptic loosening of his prosthesis, which was why he was experiencing thigh and grown pain. We designed Keyure, a tougher hip implant that would reduce the incidence of osteolysis and the need for a revision arthroplasty.
