Evaluation of Combined Anatomic Anterior Cruciate Ligament and Anterolateral Ligament Reconstruction in Anterolateral Rotatory Instability of the Knee

Some studies has demonstrated improved dynamic rotational stability with a double bundle reconstruction. However, another multiple studies did not find improved functional rotational stability, also cost and time needed and the increased incidence of cyclops syndrome are causes of technique limitation. We aimed to evaluate of results of combined anatomic ACL and anterolateral ligament reconstruction in patients with anterolateral rotatory instability of the knee. Twenty patients with chronic ACL insufficiency were subjected to combined anatomic single-bundle ACL reconstruction and anterolateral ligament reconstruction by semitendinosus and gracilis tendons. International Knee Documentation Committee (IKDC) subjective knee evaluation form (page 76, 77) was filled and scores were recorded. The results of this technique show excellent (normal) results in 18 patients grade A according to objective IKDC and very good (near normal) in 2 patients.  Range of motion at 3 months follow up was limited to 90° to 110° in 7 patients, all these patients were improved with physiotherapy and rehabilitation programs  with no need to other management.Isometric ALL is highly important to prevent tight lateral compartment of the knee and prevent limited range of motion and lateral side knee pain. There is no major complication associated with this technique to limit its use.
