ABSTRACT
PURPOSE: We performed transtibial single and double bundle reconstruction of the posterior cruciate ligament using the allo-achilles tendon and compared the results of single bundle reconstruction and double bundle reconstruction both clinically and radiologically. MATERIALS AND METHODS: This study included 41 cases of posterior cruciate ligament reconstruction between February 2000 and June 2007 that had data available for at least 2 years of follow-up. Twenty-two cases (53.7%) underwent single bundle reconstruction and 19 cases (46.3%) underwent double bundle reconstruction. Clinical results were analyzed by Lysholm score and IKDC standards scale, and the radiologic results were analyzed by the Telos(R) posterior translation test. RESULTS: The average Lysholm score at last follow-up was 85.4+/-4.7 in the single bundle group and 87.5+/-5.1 in the double bundle group. IKDC scores were grade A in 4 (18.2%), grade B in 14 (63.6%) and grade C in 4 (18.2%) in the single bundle group; they were 1 (15.3%), 15 (78.9%) and 3 (15.8%) in the double bundle group. Telos(R) posterior translation test scores were 5.06 mm (3.04-7.43 mm) in the single bundle group, and 4.04 mm (2.18-7.20 mm) in the double bundle group. There was significant improvement in clinical and radiological scores in both groups (p0.05). CONCLUSION: Further study with longer term follow-up is needed.
