The significance of the posterior cruciate ligament(PCL) in the stability of the knee and the necessity for surgical repair of its tears are still controversial. The purpose of this study is to present the short term results of surgical repair
and
Kennedy LAD augmentation for 15 cases with PCL injury.
In 14 patients (15 knees), them torn PCL was repaired with pullout suture technique and Kennedy LAD augmentation was done june 1993 to june 1994. The follow-up period ranged from 12 months to 25 months(average, 18months). The main causes of
injuries
were traffic accidents in 12. Thirteen of the patients were men and one was a woman, ranging in age from 17 to 52 years(average, 35 years). 10 knees were acute injury and repaired at average 9 days after injury and 5 knees were chronic injury and
repaired at average 7 weeks after injury. There were 11 cases that had combined injuries(4 ACL injuries, 4 meniscus injuries, 3 MCL injuries etc). In eight knees, the tear was in mid substance area and in five it was near femoral attach site and
in
two
it was near tibial attach site.
Postoperative results were evaluated by roentgenographic evaluation of posterior sagging and Lysholm knee score. 11 knee were stable but 4 knees were unstable posteriorly during postoperative follow-up period. 3 chronic injuried knees were
included
in 4
posteriorly unstable knees. There are 7 combined knee injuries in 11 stable knees and no combined injuries in unstable knees and average Lysholm knee score was 89.7 in stable knees and 90 in unstable knees and there was no significant difference
between
two groups.
On the basesd of this study, surgical repair with pullout suture technique and augmentation with Kennedy LAD in acute PCL injury is a one of the good method for preventing posterior sagging but more longer follow-up period and more cases must be
needed
to accept this method.
