2021 Annual Meeting Knee Access Pass-Sensitivity of Preoperative Imaging for Patellofemoral Instability

Sensitivity of Preoperative Imaging for Patellofemoral Instability

Video Transcription

Video Summary

The video is a presentation by Hayden Baker on the study of sensitivity of preoperative imaging for patellar femoral instability. Patellar instability is common in young athletes, and first-time patellar dislocations are often treated non-operatively. However, patients with large chondral osteochondral defects or loose bodies may require operative treatment. The study aimed to determine the sensitivity of MRI and x-ray in identifying these defects and their prevalence in patients undergoing operative treatment for patellar instability. The results showed that both MRI and x-ray poorly identified loose bodies and osteochondral defects. Surgeons should consider performing a diagnostic knee arthroscopy to assess for these conditions. The study was limited by its retrospective nature and inclusion bias. No credits were mentioned. (159 words)
