Abstract:
PURPOSE: We compared the anteroposterior translation and the internal-external rotation of the tibia in stable knees without an anterior cruciate ligament (ACL) injury with those of ACL injured knees by using a navigation system and we report the objective data. MATERIALS AND METHODS: Forty-four patients who were treated for a meniscal tear without ACL injury were allocated to the stable group, and 41 patients were allocated to the ACL injury group. The anteroposterior displacement and the rotation of the knees were measured in 0, 30, 60 and 90 degrees of flexion with using the Orthopilot(R) navigation system. RESULTS: The mean total rotation values were 18.8degrees+/-4.5degrees, 31.4degrees+/-4.2degrees, 30.1degrees+/-5.1degrees and 29.2degrees+/-5.9degrees at 0, 30, 60 and 90 degrees of flexion, respectively, in the stable group and 22.7degrees+/-6.9degrees, 37.6degrees+/-5.8degrees, 34.0degrees+/-9.4degrees and 31.8degrees+/-8.8degrees at 0, 30, 60 and 90 degrees of flexion, respectively, in the ACL injury group. CONCLUSION: The quantitative values for anteroposterior translation and rotations of stable and ACL injured knee were obtained using a navigation system.
