At the 6 weeks examination time point (i.e., 3 weeks after the last COX-2 inhibitor application), the failure load in the COX-2 inhibitor group was lower than it was at the 3 weeks examination time point. The failure load of the controls was higher after 6 weeks than it was at the 3-week examination time point, as well as compared to the COX-2 inhibitor group at the same examination time point. A decrease of the failure load of the tendon graft tended to correlate with an increase of the concentration of PGE2 (p = 0.056)
