Fifty-one-year survival of a Judet polymethylmethacrylate hip prosthesis
Simon Kovac̆; Venc̆eslav Pis̆ot; Rihard Trebs̆e; Aleksander RotterHip
Revision arthroplasty of a Judet polymethylmethacrylate (PMMA) hip hemiprosthesis was performed 51 years after implantation. This makes it the first implant to have survived for longer than 50 years. No signs of aggressive osteolysis were found on histologic analysis, which confirms good tissue tolerance for PMMA. Judet’s hip prosthesis did not follow the concept of low-friction arthroplasty; nevertheless, it represents an important step in the development of the hip prosthesis currently used.
