AOSSM 2022 Annual Meeting Recordings - no CME-Damage of Dogma: Blood in the Joint and Meniscus Repair

Video Transcription

Video Summary

The video discusses three commonly accepted beliefs, or dogmas, in the field of orthopedics regarding meniscal injuries and their healing potential. The first dogma is that meniscus repairs done in conjunction with ACL reconstruction have higher healing rates compared to isolated repairs. However, research shows conflicting results, with some studies suggesting no significant difference in healing rates. The second dogma is that microfracture of the notch improves meniscal healing, but studies have shown mixed results regarding its effectiveness. The third dogma is that blood in the joint is beneficial for meniscal healing. However, research indicates that blood can have catabolic effects on meniscal tissue, leading to degradation. The video further presents research findings on the effects of blood components, such as monocytes and lymphocytes, on meniscal tissue, suggesting sustained catabolic effects. The video concludes by suggesting the need for reevaluation of techniques that increase bleeding in the joint and minimizing the use of microfracture in certain cases. The speaker emphasizes the importance of questioning dogmas and further research on meniscal healing. The video indicates that the speaker is affiliated with Duke University and acknowledges funding sources and collaborators.
