Unicondylar polycentric knee

Unicondylar Polycentric Knee 7.5.2 The Total Condylar Knee 7.9 Acknowledgments... 

At the Mayo Clinic, Polycentric UKA was performed only on patients with unicondylar disease (osteoarthritis) (Jones et al. 1981, Skolnick, Bryan, and Peterson 1975). An initial assessment was based on radiographic screening. However, the UKA implantation technique involved the same exposure as in TKA, so that both compartments could be directly examined and evidence of unicompartmental disease visually confirmed. Mallory also reported the utility of Polycentric UKA in the treatment of post-traumatic arthritis resulting from fracture-induced deformity of the knee (1973).
