METHOD OF CHOICE OF TACTICS IN BILATERAL ENDOPROSTHESIS REPLACEMENT OF KNEE JOINT IN PATIENTS WITH CONCOMITANT DISEASES Russian patent published in 2016 - IPC A61B5/00 A61B17/56 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to traumatology and orthopaedics, and can be used for choosing a tactics when treating bilateral endoprosthesis replacement of knee joint in patients with concomitant diseases Estimation of comorbidity index Charleson is performed. Estimation of the risk of venous thromboembolic complications is performing using Kaprini scale. Estimation of degree of severity using classification of patient's objective status of American society of anaesthesia (ASA). When combined 4 degree at ASA with comorbidity Charleson index above 5 points and the risk of venous thromboembolic complications by Kaprini scale of more than 12 points knee replacement is not performed. If the comorbidity Charleson index is 4-5 points, ASA severity level is 3 and evaluation of venous thromboembolic complications as per Kaprini scale is 9-11 points patient is sent to the relevant department for the preparation to the arthroplasty. At Charleson index up to 4 points, 1 or 2 severity degree as per ASA, assessment of venous thromboembolic complications as per Kaprini scale up to 8 points endoprosthesis of knee joint is performed.

EFFECT: method allows to assess the risks of surgical intervention, reduce mortality in arthroplasty and improve quality of life of patients by assessing the most significant risk factors.
