Orthobiologic Standardization and Clinical Outcome Measurement.

There is a pressing need for the standardization of orthobiologics, considering the cellular components, concentrations, and methods of injections may vary wildly, currently without significant standards of care. There is a growing body of evidence that these factors matter significantly for patient outcomes, so it is imperative that orthobiologic constituents are measured and standardized. Cell counts may be performed for platelet-rich plasma and bone marrow aspirate-based injections, whereas adipose should have standardized processing techniques as cellular quantification is more difficult.
