Short-term results of primary total knee replacement: the experience of the Tashkent Medical Academy and Wiltze Memorial hospital

Abstract

Introduction:To analyze and evaluate the short-term results of 82 patients after primary total knee replacement (TKR)Methods:A prospective study of 82 patients (54 women and 28 men) with 82 TEC operations was conducted at the Multidisciplinary clinic of the Tashkent Medical Academy (Tashkent, Uzbekistan) and the Wiltse Memorial hospital (Suwon, Republic of Korea) from November 2018 to January 2020. The age of patients ranged from 52 to 87 years (average age 61 years). The diagnosis of grade 3 – 4 osteoarthritis of the knee (Kellgren and Lawrence) was confirmed in all patients. The hospital for Special Surgery (HSS) scale, volume of movement, visual analog pain scale (VAS), and patient satisfaction questionnaire with the Knee Society Knee Scoring System were used as functional assessment criteria.Results:The mean duration of follow-up and hospitalization was 16 months (±6.7) and 11 days (±2.6), respectively. The average volume of movements was 100, 6⁰ (±4, 5⁰) at the end of the observation period. All patients demonstrated adequate knee stability and returned to their previous daily activities. YOUR average score was 1.8 (±3.3) points over a 6-month period. Satisfaction with the outcome of the operation was 82.7 % in the 12-month postoperative period. In the study, there was not a single case of postoperative mortality, periprosthetic infection, revision surgery.Conclusion:To date, in the course of clinical observation of patients with osteoarthritis of the knee who underwent primary TKR, the results were found to be satisfactory. Also, further research with a large cohort and subsequent long-term monitoring is needed, and the question of creating a single register and institutional databases is raised, in view of the expected increase in the number of revision interventions.
