Knee X-Ray showdown: which view is best for surgery planning?
NCT ID NCT07493733
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two different X-ray views—full-leg standing and Rosenberg—to measure a specific knee angle (MPTA) in 49 patients scheduled for high tibial osteotomy. The goal is to see if one view gives more consistent or accurate measurements, which could help surgeons better plan the procedure. Participants are adults with knee arthritis who have already had both X-rays taken as part of their routine care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help surgeons choose the best X-ray view for planning knee realignment surgery, potentially improving outcomes.
- What could go wrong
- This is a small, early-stage observational study with only 49 participants. It does not test a treatment, so it won't directly change patient care.
