Estudio baropodométrico en pacientes tratados mediante artroplastia total de rodilla.

Knee osteoarthritis determines a decrease of the load of the affected limb and a pattern usually dominance of external support plantar arc. The purpose of this study is to determine whether a significant change in this pattern is? after implantation of a primary total knee arthroplasty (TKA), measuring plantar pressures in both feet by electronic baropodometry previously and 4 months after surgery, in static and dynamic. Plantar pressures of 30 patients are analyzed, who underwent primary TKA at the University Hospital Doctor Peset between 2013 and 2015. In addition, it has also been determined if there is a correction on the anatomical axis after surgery. Using nonparametric test (Wilcoxon test for paired data, U Mann Whitney), we observed a significant change in the angle from median values of 1.2º varus to 4.9º valgus postoperatively, a median decrease of plantar pressure in both feet and a redistribution of axial load, increasing in the operated limb. We conclude that, 4 months after surgery, there is a tendency to “normalization” of the tread in patients undergoing TKA. This is conditioned by improving pain and function as axis realignment occurs.
