  • Effect of autologous fibrin clot on tendon-bone healing after anterior cruciate ligament reconstruction

    ObjectiveTo observe the effect and significance of autologous fibrin clot on tendon-bone healing after anterior cruciate ligament (ACL) reconstruction.MethodsBetween October 2014 and January 2016, 34 patients (34 knees) with ACL injury were enrolled in the study. During ACL reconstruction, autologous fibrin clot was used in 17 cases (trial group) and was not used in 17 cases (control group). The anterior drawer test, Lachman test, and axial displa-cement test were positive in 2 groups before operation. There was no significant difference in gender, age, causes of injury, injury side, disease cause, and preoperative knee joint activity, Lysholm score, and American Hospital for Special Surgery (HSS) score between 2 groups (P>0.05), with comparable. The results of anterior drawer test, Lachman test, and axial displacement test were recorded and compared between 2 groups after operation. The knee joint activity, Lysholm score, and HSS score were used to evaluate the knee function recovery at 6, 24, and 48 weeks after operation; the graft signal intensity, graft signal to noise ratio, bone tunnel expansion, and graft tendon-bone node T2 value were measured.ResultsAll patients were followed up 48 weeks. Surgical incision healed at stage I. No joint infection and joint adhesion occurred. The drawer test, Lachman test, and axial shift test were negative in 2 groups. At 6, 24, and 48 weeks after operation, the Lysholm score of trial group was significantly higher than that of control group (P<0.05); there was no significant difference in knee joint activity between 2 groups (P>0.05). The HSS score of trial group was significantly higher than that of control group at 24 and 48 weeks (P<0.05), but no significant difference was found at 6 weeks (P>0.05). MRI measu-rement showed that there was significant difference in graft signal intensity, bone tunnel expansion, and graft signal to noise ratio between 2 groups at 6, 24, and 48 weeks after operation (P<0.05). There was no significant difference in graft tendon-bone node T2 value between 2 groups (P>0.05) at 48 weeks after operation, but difference was significant at 6 and 24 weeks (P<0.05).ConclusionAutologous fibrin clot can effectively enhance graft revascularization, and accelerate the process of tendon-bone healing after ACL reconstruction.
