Abstract

Background: The purpose of this study was to determine whether high BMI affect short-term clinical and radiologic outcomes of robotic-assisted total knee arthroplasty (TKA) by comparing the clinical outcomes, radiologic outcomes and complications between high BMI and normal patients.

Methods: We retrospectively compared the short-term clinical and radiological outcomes of 424 knees (408 patients). The patients were divided into four groups: BMI < 24.9 kg/m² (normal); BMI between 25.0 and 29.9 kg/m² (overweight); BMI between 30.0 and 34.9 kg/m² (obese class I) and BMI between 35.0 and 39.9 kg/m² (obese class II). Clinical and radiologic outcomes were evaluated.

Results: There was no significant difference in radiologic outcomes between those groups (p > .05). Furthermore, there was no significant difference in operation time, drainage volume, fall in hemoglobin, post-operative CRP and complications, including periprosthetic fracture and periprosthetic joint infection (PJI), between those groups.

Conclusion: High BMI does not affect short-term clinical and radiologic outcomes in robot-assisted TKA.

高体重指数是否会影响机器人辅助全膝关节置换术的短期临床和放射学结果？

背景：本研究旨在通过比较高体重指数患者和正常患者的临床结果、放射学结果和并发症，确定高体重指数是否会影响机器人辅助全膝关节置换术（TKA）的短期临床和放射学结果：我们回顾性比较了 424 个膝关节（408 名患者）的短期临床和放射学结果。患者分为四组：体重指数小于 24.9 kg/m2（正常）；体重指数介于 25.0 至 29.9 kg/m2（超重）；体重指数介于 30.0 至 34.9 kg/m2（肥胖 I 级）；体重指数介于 35.0 至 39.9 kg/m2（肥胖 II 级）。对临床和放射学结果进行了评估：结果：两组患者的放射学结果无明显差异（P > .05）。此外，两组在手术时间、引流量、血红蛋白下降、术后 CRP 和并发症（包括假体周围骨折和假体周围关节感染 (PJI)）方面也无明显差异：结论：高体重指数不会影响机器人辅助 TKA 的短期临床和放射学结果。
