Abstract
PURPOSE
Posterior cruciate ligament (PCL) injury has a reported incidence of 3-20 %. PCL reconstruction is aimed at reducing onset of premature articular degeneration and improving function. Numerous operative techniques have been described with varying degrees of result consistency.
METHODS
We evaluated 15 patients treated for isolated primary posterior cruciate ligament injury with a mean follow-up of 4.1 years (range one to nine). Post-reconstruction clinical assessment included the Lysholm and Tegner knee scoring scale, international knee documentation committee (IKDC) ligament evaluation, and KT2000 arthrometer assessment.
RESULTS
On the Lysholm knee score 11 patients (73 %) had excellent results, three patients (20 %) had good results and one patient (7 %) had a poor result. On the Tegner activity score the majority of patients scored 7-8 with a return to high level sports. At the final follow-up, the post-reconstruction IKDC score was normal or nearly normal (A and B) in 14 (93 %) patients, and abnormal (C) in one (7 %) patient. According to KT-2000 arthrometer measurements at final follow-up review, 11 patients (73 %) were rated as normal (A, 0-2 mm), and four patients (27 %) as nearly normal (B, 3-5 mm). These results were independent of age, mechanism of injury, time elapsed to surgical reconstruction, and length of follow-up.
CONCLUSIONS
Despite being a technically demanding procedure, the outcomes reported in this study show that single bundle transtibial arthroscopic PCL repair using four strands hamstring autograft provides satisfactory and consistent functional outcomes.
