Weight gain after total knee arthroplasty had a negative association with SF-36 pain and function scores, according to study results.
Researchers identified 1,545 patients who underwent primary total knee arthroplasty (TKA) and recorded BMI and patient-reported outcome measures preoperatively and for up to 3 years postoperatively.
Results showed patients who gained 10% or more over their preoperative BMI following TKA had significantly smaller improvements in physical function, as well as a significant reduction in the rate of improvement of SF-36 pain score. The researchers also found patients who had a high preoperative BMI or preoperative WOMAC function score showed a smaller improvement in WOMAC function score vs. patients with lower preoperative BMI or WOMAC function scores. There was a statistically significantly negative association between improvement in WOMAC pain score and preoperative BMI and WOMAC pain scores, according to the researchers.
Study results also showed men had greater improvement in postoperative SF-36 function and pain scores, whereas older patients had slower improvement. – by Casey Tingle
