  • Purpose : To evaluate of the surgical outcome of primary repair in anterior cruciate ligament rupture. Material & Method : Twenty-five patients underwent arthroscopic primary repair of ACL. We performed pull-out suture of ruptured ligament in 18 cases, and suture and augumentation with gracillis & semitendinosus in 7 cases. At follow up, the International Knee Documentation Committee(IKDC) scale & Lysholm score were used to grade outcome, and also the KT-2000 arthrometer was used to evaluate objective ligament laxity. Results : In analysis of IKDC scale, final evaluation group were group A in 3 cases, group B in 13 cases, group C in 9 cases. The mean value of Lysholm score was 83 points. In KT-2000 arthrometer examination, mean anterior translation was 3.9mm at 201b, 7.3mm at 30lb. The mean difference value between injured knee and uninjured knee was 1.1mm at 201b, 2.29mm at 301b. There was statistical significance in mean difference value between injured and uninjured knee. Conclusion : By analysis of clinical & objective data, we could confirm that the mid-term result of ACL suture is not satisfactory. So, we recommend that ACL reconstruction would be done in young active patient rather than suture.

  • Purpose: (1) To evaluate the trabecular pattern at the femoral attachment of the posterior cruciate ligament (PCL) in patients with a PCL injury; (2) to analyze bone microarchitecture by applying gray level co-occurrence matrix (GLCM)-based texture analysis; and (3) to determine if there is a significant relationship between bone microarchitecture and posterior instability. Materials and Methods: The study included 96 patients with PCL tears. Trabecular patterns were evaluated on T2-weighted MRI qualitatively, and were evaluated by GLCM texture analysis quantitatively. The grades of posterior drawer test (PDT) and the degrees of posterior displacement on stress radiographs were recorded. The 96 patients were classified into two groups: acute and chronic injury. And 27 patients with no PCL injury were enrolled for control. Pearson's correlation coefficient and one-way ANOVA with Bonferroni test were conducted for statistical analyses. This protocol was approved by the Institutional Review Board. Results: A thick and anisotropic trabecular bone pattern was apparent in normal or acute injury (n = 57/61;93.4%), but was not prominent in chronic injury and posterior instability (n = 31/35;88.6%). Grades of PDT and degrees of posterior displacement on stress radiograph were not correlated with texture parameters. However, the texture analysis parameters of chronic injury were significantly different from those of acute injury and control groups (P < 0.05). Conclusion: The trabecular pattern and texture analysis parameters are useful in predicting posterior instability in patients with PCL injury. Evaluation of the bone microarchitecture resulting from altered biomechanics could advance the understanding of PCL function and improve the detection of PCL injury.
