This is a prospective, randomized, controlled, third-party blinded, multicenter, interventional evaluation of inguinal hernia repair comparing Strattice to light weight polypropylene mesh. Performance and outcomes measures to be compared include postoperative resumption of activities of daily living, nature and incidence of short- and long-term pain and complications, and incidence of hernia recurrence.
