“…It is now fairly clear that, in order to restore varus stability and limit coupled posterolateral translation in patients with chronic posterolateral knee instability, it is important to reconstruct the fibular collateral ligament, the popliteus tendon, and the popliteofibular ligament [27][28][29] as well as any injured cruciate ligaments simultaneously [30][31][32][33] . Most previous reports on posterolateral knee reconstructions were primarily descriptions of the techniques and provided few patient outcomes [34][35][36][37][38][39][40] . Our anatomic posterolateral knee reconstruction technique restored the native function of these three important knee stabilizers in the majority of patients with these chronic injuries.…”

Background: Chronic posterolateral knee injuries often result in substantial patient morbidity and functional instability.The clinical stability and functional outcomes following anatomic reconstructions in patients with a chronic posterolateral knee injury have not been determined, to our knowledge.Methods: A two-center outcomes study of sixty-four patients with grade-3 chronic posterolateral instability was performed. The patients were evaluated subjectively with the modified Cincinnati and International Knee Documentation Committee (IKDC) subjective scores and objectively with the IKDC objective score.Results: Eighteen patients had an isolated posterolateral knee reconstruction, and forty-six patients underwent a singlestage multiple-ligament reconstruction that included reconstruction of one or both cruciate ligaments along with the posterolateral knee reconstruction. The average duration of follow-up was 4.3 years. The fifty-four patients who were available for follow-up had an average total Cincinnati score of 65.7 points. A significant improvement was found between the preoperative and postoperative IKDC objective scores for varus opening at 20°, external rotation at 30°, reverse pivot shift, and single-leg hop.Conclusions: An anatomic posterolateral reconstruction resulted in improved clinical outcomes and objective stability for patients with a grade-3 posterolateral knee injury.
