Fig. 7From: Effect of COX-2 inhibition on tendon-to-bone healing and PGE2 concentration after anterior cruciate ligament reconstructionAt the 3 weeks examination time point, the bone density in the tunnel aperture section was significantly reduced in the COX-2 inhibitor group in comparison to the controls. An increase in bone density in the tunnel aperture section was temporally associated with an increased PGE2 concentration. The bone density in the tunnel aperture section was significantly increased as compared to the mid-tunnel section in all of the examination groupsBack to article page
