Weight loss showdown: surgery vs diet before knee or hip replacement
NCT ID NCT05156762
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aimed to see if bariatric surgery or medical weight loss (diet and exercise) helps severely obese patients lose enough weight to safely undergo hip or knee replacement. Only 3 people took part before the study was stopped early. The goal was to get patients to a BMI of 40 or lower before surgery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- bariatric surgery (sleeve gastrectomy or gastric bypass) and medical weight loss (diet, exercise, counseling)
- What this could lead to
- If successful, this could show that weight loss before joint replacement improves surgical outcomes and reduces complications.
- What could go wrong
- The trial was terminated early with only 3 participants, so results are very limited. Weight loss may not be enough to improve joint replacement outcomes.
