Functional state of patients with an increased body mass index in the early rehabilitation period after total knee joint arthroplasty (preliminary report)

Abstract

Purpose To assess the impact of increased body mass index on intraoperative indicators and early postoperative clinical and functional results in total knee arthroplasty Materials and methods We studied 74 patients with severe gonarthrosis. The patients were divided into four groups, depending on their body mass index (BMI). The first group consisted of 27 people (comparison group) with normal BMI (18.5–24.9). The second group included 22 persons with a BMI range of 25–34.9. The third group included 16 patients with BMI that ranged 35–39.9, and the fourth group included nine patients with BMI ≥ 40. Results The results of the study confirmed the fact of a slight increase in the duration of the operation and intraoperative blood loss in patients with obesity. However, a three-month period examination after surgery showed comparable efficacy of arthroplasty in reducing pain and functional outcomes achieved in all groups. Conclusion Total knee arthroplasty is effective in severe gonarthrosis in all patients, regardless of BMI. Anatomical and functional status of patients improved significantly in the postoperative period in all groups of the patients studied.
