Clinical Outcome of Anatomical Arthroscopic Posterior Cruciate Ligament Reconstruction with Achilles Tendon Allograft

Abstract

Background: Regarding this, the present study aimed to assess the clinical outcome of anatomical arthroscopicposterior cruciate ligament (PCL) reconstruction using Achilles tendon allograft.Methods: This cross-sectional retrospective study was conducted on 24 patients undergoing anatomical arthroscopicPCL reconstruction using Achilles tendon allograft during 2008-2014. The patients were examined in terms of kneestability by clinical examinations and KT-2000 arthrometer, as well as regarding health and knee status, over a meanfollow-up of 36 months. In addition, the 36-Item Short-Form Health Survey (SF-36), International Knee DocumentationCommittee Subjective Knee Form (IKDC), Knee Injury and Osteoarthritis Outcome Score (KOOS), Kujala, and Lysholmwere adopted to collect data.Results: The participants had a mean age of 30±8 years and a mean body mass index of 25±2 kg/m2. Based on theresults of the SSD-KT2000 arthrometer, 12.5%, 34.37%, 28.12%, and 25% of the patients had normal, nearly normal,abnormal, and severely abnormal laxity, respectively. In addition, the mean KOOS, Lysholm, IKDC, and Kujala scoreswere estimated at 73.92±15, 79.50±17, 58.20±10.47, and 80.06±16, respectively. The patients with concomitant partialmeniscectomy had a significantly lower IKDC score (P<0.01).Conclusion: Based on the findings, the use of Achilles tendon allograft in the surgical reconstruction of PCL would yieldexcellent results both subjectively and objectively. In addition, patient selection and surgeon's choice and preferenceshould be considered in determining the treatment plan for the patients.Level of evidence: III
