Single-Stage Reconstruction of Both Cruciate Ligaments

OBJECTIVES: Isolated Anterior Cruciate Ligament (ACL) and Posterior Cruciate Ligament (PCL), or central pivot lesions are rare. These are frequently associated with collateral ligaments injuries. The purpose of this retrospective study was to evaluate clinical and functional outcomes of 4 patients with acute ACL and PCL injury who underwent a simultaneous single-stage arthroscopic reconstruction. METHODS: The inclusion criteria were patients with isolated ACL and PCL injuries, with a minimum follow-up of 2 years. We evaluated the type of graft used, the surgical technique and postoperative complications. The scales used for clinical evaluation were the Knee Society Score (KSS), IKDC, Lysholm and Tegner. Knee stability was assessed using the KT-1000 arthrometer. RESULTS: Three men and one woman, with an average age of 48 years (45 to 56 years) were evaluated. Three presented a sport injury and one a car accident. Mean follow-up was 8 years. In all patients allograft was used for ligament reconstruction. Average postoperative results were: KSS 74-82, Lysholm 76, IKDC 63 and Tegner 6. KT-1000 arthrometer showed an average difference of 4mm compared to the contralateral knee. One patient underwent reintervention due to meniscal injury. CONCLUSION: ACL and PCL simultaneous single-stage reconstruction is a really demanding surgery. We achieved good results using allograft for both ligaments reconstruction. No clinical or functional postoperative complications were recorded.
