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 (p<0.001). However, these differences were not statistically significant (p>0.05).
CONCLUSION
Further study with longer term follow-up is needed.
