Background: Regarding this, the present study aimed to assess the clinical outcome of anatomical arthroscopic
posterior cruciate ligament (PCL) reconstruction using Achilles tendon allograft.
Methods: This cross-sectional retrospective study was conducted on 24 patients undergoing anatomical arthroscopic
PCL reconstruction using Achilles tendon allograft during 2008-2014. The patients were examined in terms of knee
stability by clinical examinations and KT-2000 arthrometer, as well as regarding health and knee status, over a mean
follow-up of 36 months. In addition, the 36-Item Short-Form Health Survey (SF-36), International Knee Documentation
Committee Subjective Knee Form (IKDC), Knee Injury and Osteoarthritis Outcome Score (KOOS), Kujala, and Lysholm
were 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 the
results 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 scores
were estimated at 73.92±15, 79.50±17, 58.20±10.47, and 80.06±16, respectively. The patients with concomitant partial
meniscectomy 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 yield
excellent results both subjectively and objectively. In addition, patient selection and surgeon’s choice and preference
should be considered in determining the treatment plan for the patients.
