Using KSS, WOMAC and IKDC score systems the authors evaluated functional results of 64 total (TKA) and unicompartmental (UKA) knee arthroplasties performed in department of knee pathology of Vreden’s Russian Research Institute Travmatology and Orthopaedics from 2001 till 2006. Before joint replacement there was no significant difference in magnitude of performance deficit between both groups. After 5-10 years (7 in average) all patients had similar pain relief but activities of daily living and level of physical performance, including high flexion, were significantly higher in UKA group than TKA. KSS and WOMAC score systems did not reflect this important difference in physical capacities of UKA and TKA patients comparing to IKDC.
