Summary

This study examined nearly 100,000 people who had knee replacement for arthritis to see if those who previously had weight-loss surgery faced different risks of complications or needing another surgery. Researchers focused on how body weight at the time of knee replacement and the type of weight-loss surgery affected outcomes. The goal is to help doctors better predict and improve results for these patients.
