Case presentation - Rotator Cuff Repair with Biologic Augmentation (Bursa)

Video Transcription

Video Summary

The video discusses the use of subacromial bursa for rotator cuff repairs. Animal studies have shown that tendon healing cells originate from the peritoneum, leading to the hypothesis that the bursa is the peritoneum of the rotator cuff. The bursa is readily available, inexpensive, and has shown greater proliferative ability compared to concentrated bone marrow. Cellular composition of the bursa is dominated by progenitor cells and fibroblasts. The process involves taking blood, creating a fibrin clot, and releasing the bursa. Application of the autologous fibrin clot after rotator cuff repair still needs improvement. Human outcomes show six failures out of several patients, but colony forming units have no impact on failure rate. The bursa is considered a good option for rotator cuff repairs. The speaker credits Russ Warren for his guidance. No other credits are mentioned.
