BioEnthesis Interpositional Biphasic Cancellous Allograft

Clinical Challenge

Too many rotator cuff repairs result in re-tear. Why? Healing relies on reincorporation of tendon
into the bone at the enthesis. See what the literature says about the enthesis:

Indication for Use:

BioEnthesis is indicated to provide a matrix for the repair or reconstruction of the bone of the enthesis within the rotator cuff.

Contraindications:

BioEnthesis is contraindicated for use in any patient in whom soft and hard tissue implants are contraindicated. This includes any pathology that would limit the blood supply and compromise healing, or evidence of a current infection. BioEnthesis is contraindicated where the allograft is intended as structural support in load-bearing bone, and articular cartilage surfaces.
