2023 AOSSM Annual Meeting Recordings with CME-Reliability of Posterior Tibial Slope Measurement on Magnetic Resonance Imaging Versus Computed Tomography

Reliability of Posterior Tibial Slope Measurement on Magnetic Resonance Imaging Versus Computed Tomography

Video Transcription

Video Summary

The video discusses the reliability of posterior tibial slope (PTS) measurements on MRI versus CT scans. The speaker explains that greater PTS measurements are associated with increased rates of ACL injury and graft failure. The study aimed to compare PTS measurements medially and laterally on MRI and CT. The study included 46 knees from 45 patients and used a validated method to measure the PTS. The results showed poor to moderate agreement and high variability in PTS measurements between MRI and CT at both the medial and lateral plateaus. The speaker concludes that CT may be necessary for accurate measurements and suggests further studies in relevant patient cohorts. <br /><br />No credits were mentioned.
