Bone Marrow Stimulation for Arthroscopic Rotator Cuff Repair: A Meta-analysis of Randomized Controlled Trials Am. J. Sports Med. (IF 4.8) Pub Date : 2024-02-08 Eoghan T. Hurley, Bryan S. Crook, Richard M. Danilkowicz, Laith M. Jazrawi, Raffy Mirzayan, Jonathan F. Dickens, Oke Anakwenze, Christopher S. Klifto
Background:Bone marrow stimulation (BMS) has been proposed to augment healing at the time of arthroscopic rotator cuff repair (ARCR) by creating several bone marrow vents in the footprint of the rotator cuff, allowing mesenchymal stem cells, platelets, and growth factors to cover the area as a “crimson duvet.”Purpose:To perform a meta-analysis of randomized controlled trials (RCTs) to compare the outcomes

Evaluation of Spin Bias in Systematic Reviews and Meta-analyses of Rotator Cuff Repair With Platelet-Rich Plasma Am. J. Sports Med. (IF 4.8) Pub Date : 2024-02-07 Samuel G. Moulton, Matthew J. Hartwell, Brian T. Feeley
Background:The use of platelet-rich plasma (PRP) in orthopaedics continues to increase. One common use of PRP is as an adjunct in rotator cuff repair surgery. Multiple systematic reviews and meta-analyses have summarized the data on PRP use in rotator cuff repair surgery. However, systematic reviews and meta-analyses are subject to spin bias, where authors’ interpretations of results influence readers’
