Studies of regional blood flow at the stage of preparation for revision total knee arthroplasty

The results of rheovasographic (RVG) and Doppler ultrasound (USDG) examination of the vessels of the lower extremities study of 13 patients, aged 50-75 years, with aseptic instability of the components of a knee joint endoprosthesis (TKA) at the stage of preparation for revision total knee arthroplasty (RTKA). To assess the orthopedic status, we used: clinical examination, radiography of the knee joint in 2 standard and axial projections, topogram and CT scan. The results of the conducted RVG and ultrasound Doppler studies indicate a decrease in the overall physiologically acceptable level of blood filling of the muscles of the lower extremities at rest, mainly in the thigh area, and a low reserve for restoring regional blood flow after revision, compared with primary prosthetics.
