This is a prospective study, which included patients followed for advanced knee osteoarthritis (N = 10, mean age 72 ± 7.9 years) candidates for total knee arthroplasty (TKA). Functional status was carried out by WOMAC score. Posturological and dynamic baropodometric analysis were carried out before (M0) and 4 weeks after TKA (M1) using a PRESSCAM® stabilometry platform (SIDAS®, 38,000 VOIRON, MEDICAPTEURS®). Data provided information on the distribution of foot pressures on the operated and non-operated side. Comparison of baropodometric parameters was performed before (M0) and 4 weeks after TKA (M1). The total WOMAC score decreased significantly after TKA (P <0.05). The changes in posturographic and dynamic parameters of surfaces, pressure and force measured at M1 were not significant. At M0, the stabilogram position was deviated in all patients towards the contralateral operated side. At M1, we noted normalization of the stabilogram position in 2 patients. Surface of COP ellipse was superior to 1 cm2 (%) in one patient before TKA and in 2 patients after TKA. Comparison of medio lateral indexes indicated significant changes in surface area and average pressure (p<0.05). In conclusion posturographic and dynamic baropodometry analysis could help clinicians to correct the postural instability after total knee arthroplasty. Long-term follow-up studies will be able to confirm the use of baropodometry in evaluating TKA.
