Double-bundle PCL reconstruction using autogenous quadriceps tendon and semitendinous graft: surgical technique with 2-year follow-up clinical results.

Abstract

The objective of this study was to evaluate the results obtained from posterior cruciate ligament (PCL) reconstruction with the double femoral tunnel technique, using quadriceps tendon and semitendinous autograft, in patients with isolated PCL tears or PCL tears associated with other ligament lesions, 2 years after surgery. The study included 14 patients with isolated PCL lesions and 20 with combined ligament lesions, who underwent PCL reconstruction using the double femoral tunnel technique and were evaluated 24 months after surgery using the International Knee Documentation Committee (IKDC) and Lysholm scores, a KT-1000 arthrometer, and the graduation of the posterior drawer test. Knees were considered normal ("A") or nearly normal ("B") in 92.9% of patients with isolated lesions and in 95.0% of patients with combined tears, according to the IKDC score. Good or excellent results were obtained in 100% of patients in both groups according to the Lysholm score. Absence or outstanding reduction of posterior tibial translation was seen in 92.9% of patients with isolated lesions and in 100% of patients with combined ligament tears, in the posterior drawer evaluation. The PCL double femoral tunnel reconstruction technique using autografts was effective in restoring posterior knee stability, in isolated and/or combined PCL tears, showing remarkable clinical improvement in all patients. 2C.
