Does fat infiltration of the rotator cuff muscles contribute to increased hidden blood loss (HBL) and other risk factors during arthroscopic rotator cuff repair for rotator cuff injuries?

Patients exhibiting higher classification of fatty infiltration in the rotator cuff muscles, as well as those with more extensive rotator cuff tears, may be associated with increased levels of hidden blood loss (HBL) during arthroscopic rotator cuff repair. Factors such as Hctpost, intraoperative bleeding volume, severity of fatty infiltration, and tear size have been suggested as potential independent risk factors for HBL. Close perioperative monitoring of these parameters could contribute to improved patient safety during arthroscopic rotator cuff repair procedures.
