ABSTRACT
INTRODUCTION:
Bariatric surgery reduces obesity and knee osteoarthritis (OA) pain, but some patients improve more than others. We aimed to identify characteristics that predict this knee pain improvement.METHODS:
We reviewed NYU Langone Health bariatrics records (2002-2015) and called eligible patients reporting pre-operative knee pain. Patients were asked to rate their pain on a 10-point scale at three time points before surgery, one year post-surgery, and time of survey administration. Subjects were asked about pre-operative knee injuries and surgeries, presence of OA in other joints, and OA family history. Data were analyzed using paired t-tests and ANOVA.RESULTS:
Of 125 eligible patients reporting knee pain, we analyzed the 120 patients who had laparoscopic gastric band (LAGB) surgery. The cohort was 78.3% female, with an average age at surgery of 49.7 ± 10.2 years. There was no correlation between pre-operative body mass index (BMI) and knee pain reduction at one year post-LAGB, but the subgroup with the most BMI improvement reported the most knee improvement (p = 0.043). We found significantly better pain reduction after one year in younger patients (p = 0.009). Those with prior knee injuries improved less than those who were injury-free (p = 0.044), but a history of prior knee surgery was not similarly significant. Patients with multifocal OA improved less (p = 0.001).CONCLUSION:
Younger knee OA patients and those without prior knee injury or other OA involvement, experience more knee pain relief from LAGB weight loss surgery. LAGB may be a viable treatment option for knee OA pain, irrespective of the degree of obesity.Palavras-chave
