Purpose: to compare traditional and miniinvasive approaches to total knee replacement. 145 patients were divided in four groups. In 1 group (50 pts) we used medial parapatellar approach, 2 group (30 pts) - lateral parapatellar approach, 3 group (34 pts) - midvastus approach, 4 group (31 pts) - Q-S approach. All replacements were done by one experienced surgeon. Intraoperative blood loss, duration of surgery, results of KSS and quality of positioning of implants were measured. Mininvasive approaches to knee replacement showed decreased blood loss, improved functional results and positioning was as much perfect, as with traditional approach. Mininvasive knee replacement is very effective, but it should be performed by experienced surgeon

We have offered modified access to a knee to work out a method for restoration of extensive apparatus of the knee. 91 patients with degenerative damages of the knee were under out su-pervision. All patients were differentiated in groups according to the form of access and pa-thology of the knee. At all stages of studying the following method of investigation were made: goniometry — for estimation of the knee functional condition; electroneiromyography — for reveling deficiency of muscular activity and determination of its kind. Patient's satisfac-tion by operation was defined by means of WOMAC scale subjective indexes. The received digital material was subjected to statistical processing. Thus, it has been proved that applica-tion of the modified access to a knee offered by us in total knee arthroplasty in patients with combined contracture in comparison with traditionally applied technologies of extensive ap-paratus releasing allows in short terms to restore the volume and force of movements in a knee that reduces time of rehabilitation and improves quality of patient's life
