Post-op knee pain

Post-surgical weight loss may alleviate knee pain

Bariatric surgery with subsequent marked weight loss is likely to improve knee pain, physical function and stiffness in (morbidly) obese adult patients

Bariatric surgery with subsequent marked weight loss may reduce knee complaints in morbidly obese adults, according to research published in Obesity Reviews. Dr V A Groen from Onze Lieve Vrouwe Gasthuis in Amsterdam, the Netherlands, and colleagues conducted a systematic review of the literature and analysed data from 13 studies involving 3,837 patients receiving bariatric surgery. The effects of bariatric surgery on knee complaints in morbidly obese patients were determined using one or more assessment tools.

Although different assessment tools were used, an overall significant improvement in knee pain was seen in 73% out of the used assessments. All studies measuring intensity of knee pain, knee physical function and knee stiffness showed a significant improvement after bariatric surgery.

However, they did note that the quality of evidence was very low or too low for most of the included studies and moderate for one study.

"Bariatric surgery with subsequent marked weight loss is likely to improve knee pain, physical function and stiffness in (morbidly) obese adult patients," the authors write. "However, with the current available evidence, there is need for high-quality studies.”
