A follow-up study of arthroscopic combined reconstruction of anterior and posterior cruciate ligaments with allograft patellar tendon.
OBJECTIVE
To evaluate the therapeutic effect of combined reconstruction of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) simultaneously by using allograft patellar tendon under arthroscopy.


METHODS
From May 2003 to November 2005, 10 cases of ruptured ACL and PCL were fixated with compressed screws and reconstructed under arthroscopy with allograft patellar tendon simultaneously. The clinical results were evaluated according to IKDC, Lysholm, and Tegner clinical rating scales.


RESULTS
All patients were followed up for 12-30 months (mean: 18 months). At the last follow-up, there was no knee extension limitation and knee flexion was between 120 degree and 135 degree,with an average of 128.38 degree. The Lysholm score of the 10 cases was 66.5+/-5.6 before operation and 89.8+/-3.4 at last follow up. The difference was statistically significant (P less than 0.01). The average Tegner activity score decreased from 6.9+/-1.7 (range: 4-9) before injury to 5.5+/-1.6 (rang:2-9) at the follow-up (P equal to 0.53). At the end of follow-up, IKDC score was graded as A in 4 cases (40.0%), B in 5 (50.0%), and C in 1 (10.0%). Of the 10 patients, 8 returned to the same sports level as before injury and 2 were under the level.


CONCLUSIONS
Arthroscopic combined reconstruction of ACL and PCL with allograft patellar tendon has the advantages of minimal trauma in surgery and reliable satisfactory outcome.
