Purpose: To determine the maximal chlorhexidine concentration that does not affect chondrocyte viability in allograft.
Conclusion: Pulse lavage with 0.002% CHG does not cause significant cell death within 7 days after exposure, while CHG at concentrations >0.002% significantly decreases chondrocyte viability within 1 to 2 days after exposure and should therefore not be used for disinfection of osteochondral allograft.
