A recent clinical paper, published Feb 2017, assesses proprietary allograft processing methods including their clinical outcomes and biomechanical properties.
A systematic review was performed using searches of PubMed, EMBASE, Google Scholar, and Cochrane databases. Duplicate studies, studies not providing the allograft processing technique; and those not containing the outcomes of interest were excluded. Outcomes of interest included outcome scores, complication and failure rates; and biomechanical properties of the processed grafts.
Twenty-four studies (13 clinical, 11 biomechanical) met inclusion criteria for review. Of all the processes, the BioCleanse® Process showed the lowest failure rates (5.4%) compared to AlloTrue (5.7%); whilst aseptically processed MTF grafts showed failure rates of 6.7%. The biomechanical studies showed overall maintenance of satisfactory biomechanical properties throughout multiple testing modes.
Amongst the available literature, except for the Tutoplast® process, no notable differences were found in the clinical outcomes or biomechanical properties.

The BioCleanse® Tissue Sterilisation Process is RTI Surgical®’s proprietary process for complete sterilisation without the use of irradiation.
Studies have shown that the BioCleanse Process® does not adversely affect the biomechanical properties of allograft tissue. [1,2]
