The influence of obesity on clinical outcomes of fixed-bearing unicompartmental knee arthroplasty: A ten-year follow-up study
The Bone & Joint Journal Feb 19, 2019
Xu S, et al. - Researchers investigated whether obesity influences the clinical outcomes and survivorship ten years postoperatively in patients who underwent a fixed-bearing unicompartmental knee arthroplasty (UKA). Following 184 patients who underwent UKA between 2003 and 2007 for a minimum of ten years, it was noted that obese patients [body mass index (BMI) of ≥ 30 kg/m2] underwent UKA at a significantly younger mean age (56.5 years) than those in the control group [62.4 years; BMI of < 30 kg/m2]. In both groups, functional and quality-of-life scores improved significantly postoperatively. However, clinical outcome were poorly improved and revision rates were high ten years postoperatively among obese cases.
