Simultaneous arthroscopic ACL and PCL reconstruction using allograft Achilles tendon.

Background: Multi-ligamentous injuries to the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) are uncommon but debilitating injuries. They mostly lead in functional disabilities and further surgeries.

Hypothesis: The aim of the present study was to evaluate the outcomes of simultaneous arthroscopic reconstruction of ACL and PCL using allograft Achilles tendon.

Study Design: Case-series study.

Materials And Methods: This study was performed on patients with combined ACL-PCL injuries which attended for treatment to a referral center from January 2010 to January 2014. All of them underwent simultaneous arthroscopic reconstruction of ACL and PCL using allograft Achilles tendon. Range of motion (flexion and extension loss), giving way, anterior and posterior knee stability, proximal tibia step off, subjective assessment of knee function and patients satisfaction were evaluated at 3, 6, 12, 24 months and final follow-up. Data were analyzed by SPSS version 21 with consideration of P < 0.05 as significant difference.

Results: Among 28 included patients, 21 patients (75%) were male. Mean age of patients was 30.86 ± 7.25 years (range: 18-49 years). The mean follow-up time was 35.7 ± 6.8 months (range: 26-50 months). Our results demonstrated that knee function, stability, and range of motion were improved along the follow-up periods. At final follow-up none of the patients had giving way and all of them were completely satisfied from the surgery.

Conclusion: Simultaneous reconstruction of injured cruciate ligaments using allograft Achilles tendon resulted in appropriate functional outcomes and acceptable range of motion.

Level Of Evidence: IV.
