Risk of Revision Following Knee Arthroplasty in Bariatric Surgery Patients

NCT06433700 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 99965

Last updated 2026-02-27

No results posted yet for this study

Summary

Previous studies have investigated the outcomes of Knee Arthroplasty (KA) following Bariatric Surgery (BAS), but with substantial limitations as not stratifying for Body Mass Index (BMI) at time of KA or not addressing the type of BAS (gastric bypass, banding or sleeve). Since BMI varies greatly in patients with previous BAS, it is likely that BMI affects outcomes after KA in BAS-operated patients.

The investigators believe that stratifying for BMI would explain the contradictions with the previous research in this patient group when it comes to the risk of revision after KA.
