ASSESSMENT OF KNEE JOINT FUNCTION IN PATIENTS AFTER TOTAL KNEE ARTHROPLASTY USING THE KOOS SCALE

Abstract

The goal was to evaluate the immediate results of treatment and knee function in patients after total knee replacement. Material and methods. The study included: questioning of patients, analyzing the medical records of inpatients, analyzing the features of surgical intervention and treatment during the postoperative period. We examined 81 patients with grade 3 gonarthrosis according to Ahlbäck. The patients underwent an examination of an orthopedic traumatologist with clinical assessment of their state by the KOOS scale (The Knee injury and Osteoarthritis Outcome Score). Results. A significant reduction in the pain syndrome was observed in the period from 30 to 180 days, ranging from 38.07 (11.1-50.0) points to 86.88 (72.2-97.2) points, respectively, which in turn speeded up the rehabilitation time after endoprosthetics (p <0.05). The severity of the pain syndrome in the period of 30-90 days after surgery was significantly lower in patients with rotation-endoprosthesis (50.0 - 66.4 points) than in those with modular endoprosthesis (38.07 - 60.6 points), respectively (p <0.05). The severity of symptoms throughout the period of observation of patients after surgery was significantly lower in patients with rotation-endoprosthesis (50.0 - 65.6 - 88.8 - 92.06 points) than in those with modular endoprosthesis (35.1 - 56.9 – 82.9 - 86.2 points), respectively (p <0.05). Conclusions. The evaluation of the knee joint function restoration after endoprosthetics using the KOOS scale is very detailed, which justifies its wider use in this category of patients.
