Objectives. To identify and evaluate the factors affecting the outcome of the total knee replacement (TKR) on the basis of the study and analysis of the early results of surgical treatment forgonarthrosisin the clinicof traumatology, orthopedics and military surgery stationed in Vitebsk Regional Clinical Hospital.
Material and methods. The study included 134 patients who had undergone TKR for the 3rd – the 4th stages of gonarthrosis. Patients with the presence of valgus/varus deformity of the knee joint which was more than 10° were included in a separate group. Patients were examined by means of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaires and the Self-administered patient satisfaction scale. The average follow-up period made up 8,1 (+/-) months.
Results. The overall average score according to WOMAC before the operation was 26,8±5,8, after it – 73,2±7,8. Permanent pain syndrome was noted in 7 (5,2%) patients, 23 (17,2%) patients suffered from periodical pain in the joint area. According to the results of our study with the use of the Self-administered patient satisfaction scale intended for the evaluation of the outcome of surgical treatment, 83,8% of patients rated the immediate outcome of the operation as either «excellent» or «good», 12,5% as «satisfactory» and 3,8% of them as «bad». Intergroup differences on the analysis of the results of the study were not revealed.
Conclusions. TKR allows to achieve positive results of treatment in the majority of patients. The degree of preoperative deformation of the limb axis does not have any significant effect on patients satisfaction with the results of surgical treatment in the early postoperative period. The reserve for improving the results of TKR is seen both in the improvement of perioperative maintenance and in the increase of pre- and post-operative awareness of patients.
