Abstract

Objective: The choice of graft material for posterior cruciate ligament (PCL) reconstruction of the knee remains controversial. Commonly used grafts include hamstring tendons, bone-patellar tendon-bone (BPTB), and quadriceps tendon (QT), each with specific advantages and limitations. This study aims to evaluate the clinical outcomes of arthroscopic PCL reconstruction using quadriceps tendon grafts performed at Saint Paul General Hospital. Methods: This study was conducted at Saint Paul General Hospital to evaluate the outcomes of arthroscopic PCL reconstruction using a quadriceps tendon graft. A combination of retrospective and prospective analysis was performed on 20 patients who underwent arthroscopic PCL reconstruction using the quadriceps tendon between January 2023 and January 2025. Surgical steps included: Harvesting the quadriceps tendon graft, graft preparation and suturing, tunnel drilling using the All-inside technique, graft insertion and fixation at both ends of the tunnels. Results: A total of 20 patients (20 knees) who underwent arthroscopic posterior cruciate ligament (PCL) reconstruction using a quadriceps tendon graft were evaluated, with a mean follow-up duration of 6.9 ± 2.7 months. The average postoperative Lysholm knee score was 89.35 ± 8.65, with 90% of patients achieving good to excellent outcomes, 5% having fair results, and 5% classified as poor. Similarly, the mean IKDC 2000 score was 87 ± 6.78, with 85% of patients scoring ≥ 80 points, indicating satisfactory functional recovery, while only 15% had scores below 80. Conclusion: The quadriceps tendon graft, with its unique anatomical and biomechanical properties, demonstrated favorable outcomes in arthroscopic PCL reconstruction. It provided a safe and effective solution, allowing for early functional recovery and minimizing complications, particularly graft failure.
