Functional and radiologic results of the crimson duvet procedure in rotator cuff treatment: a randomized controlled clinical trial

Shoulder & Elbow

“…Surgeons in Santiago (Chile) are therefore to be commended for their contribution to this interesting and difficult area. 7 They undertook a singleblinded randomized controlled trial, where 123 patients undergoing an arthroscopic full thickness rotator cuff repair were randomized to either pure debridement of the insertion footprint, or footprint microfracture. The mean patient age was 58 years and the male: female split in participants was 64:59.…”

Intraoperative Channeling in Arthroscopic Rotator Cuff Repair: A Multicenter Randomized Controlled Trial

“…The results of this study do not support our hypothesis that bone channeling at the time of rotator cuff repair results in a lower retear rate and superior functional outcomes. The channeling technique has been described using other terms in the literature including microfracture, 16,17 crimson duvet, 23 and nanofracture, 20 but the procedure is fundamentally the same. The instruments used in RCTs investigating intraoperative bone channeling in arthroscopic rotator cuff repair produce channels that range from 1 to 1.5 mm in width and from 3 to 9 mm in depth, making them similar to those used in the current study.…”

“…24 One possible approach to improve healing rates is to increase such growth factors and MSCs at the repair site by “channeling” the bone. Known by various terms in the literature, including “microfracture,” 16,17 “crimson duvet,” 23 and “nanofracture,” 20 this technique involves opening communication between bone marrow of the proximal humerus and the tendon insertion site. This method of drafting local autologous cells has a low cost; is technically simple; and perhaps most importantly recruits all available growth factors, cytokines, and stem cells rather than specific factors in isolation.…”

“…En un estudio reciente realizado por un grupo local, Toro et al 8 realizan un estudio prospectivo randomizado de 123 pacientes dividiéndolos en grupos con y sin microfracturas. Confirmaron una cicatrización de 85.11% en grupo control y de 93.7% en grupo con microfracturas ( p = 0.19).…”
