Abstract:

Objective To explore the effect of tibial tunnel enlargement on the clinical outcome after anatomical single bundle anterior cruciate ligament (ACL) reconstruction. Method The clinical data of 40 patients who had received anatomical single-bundle ACL reconstruction from May 2011 to December 2012 in affiliated hospital of Cheng De medical college were reviewed. After measuring the tibial bone tunnel width through X-ray films, CT scanning and three-dimensional reconstruction, The bone tunnel enlargement is classified and defined. To evaluate the clinical outcome, range of motion (ROM), anterior drawer test (ADT), Lachman Test, pivot shift test (PST),the Lysholm Knee Scoring Scale and IKD C2000 Scoring Scale were adopted. Results During postoperative follow-up,there was no activity disabilities of joint flexion and extension. Between affected limb and the contralateral limb flexion angle there was no statistically significant difference (t=-1.844, P=0.069).There was no statistically significant difference between the two groups in ADT、Lachman test and PST (χ2=1.314,0.011,0.005, P=0.33、1.0、1.0). Comparing the preoperative Lysholm score with postoperative score in the 40 patients, There was statistically significant difference(t=-45.50, P<0.001). Comparing the preoperative IKDC score with postoperative score in the 40 patients, there was statistically significant difference (t=-25.18, P<0.001). According to tibial tunnel diameter of 3D-CT, there was no statistically significant difference among all Lysholm score in different levels (F=1.274, P=0.292), and there was no statistically significant difference between any two levels. Conclusion The tibial tunnel enlargement after anatomical single bundle ACL reconstruction has no significant effect on medium-term clinical outcomes.
