de Villeneuve FB, Jacque C, Puech S, et al. - This research was attempted to investigate the functional outcome and the implant survivorship of a morphometric total knee arthroplasty (TKA) at a minimum of 5 years follow-up. Researchers conducted a prospective observational single-center study to examine all patients undergoing primary TKA with a single design of morphometric posterior-stabilized prosthesis (Persona, Zimmer;) between May 2012 and June 2015. They applied Kaplan Meier to estimate the survivorship of the implants. They conducted 237 TKA in 235 patients with a mean age of 73 years (49-90). This is the first research to illustrate that significant improvement of the functional scores with good survivorship can be achieved at a minimum of five years follow-up with TKA using morphometric implants.
