Posterior Cruciate Ligament reconstruction with peroneus longus tendon graft: 2-Years follow-up.

Abstract

BackgroundSeveral study that evaluate the usage of peroneus longus tendon (PLT) autograft in Anterior Cruciate Ligament reconstruction shows good result. Regardless the potential, there was no study about the use of PLT autograft in Posterior Cruciate Ligament (PCL) reconstruction. The purpose of this study is to evaluate the functional outcome and donor site morbidity after single bundle PCL reconstruction using PLT autograft.MethodsPatient who met inclusion criteria, enrolled to this study and underwent single bundle PCL reconstruction using PL tendon autograft. Clinical outcomes were assessed with International Knee Documentation Committee (IKDC), Modified Cincinnati scoring systems, Lysholm score, and Serial hop test (single hop test and triple hop test) 2-year after surgery. Donor site morbidity was assessed with Foot and Ankle Disability Index (FADI) and American Orthopaedic Foot and Ankle (AOFAS) scoring system.ResultsFifteen patients fulfilled the inclusion criteria (11 males and 4 females). PLT graft diameters were 7.5–10 mm (mean: 8.30 ± 0.65 mm). Significant increase of functional score (p < 0.05) were found two years after surgery. Mean score of IKDC was 47.58 ± 11.75 pre-operative; 78.17 ± 4.52 post-operative, Modified Cincinnati was 48.86 ± 12.22 pre-operative; 79.00 ± 4.82 post-operative, Lysholm score was 49.26 ± 11.54 pre-operative; 80.20 ± 5.04 post-operative. FADI and AOFAS at donor site ankle was 93.00 ± 3.04 and 93.26 ± 4.20, respectively. Serial hop test showed good result.ConclusionPCL reconstruction using peroneus longus tendon autograft shows good functional outcome of the knee based on IKDC, Modified Cincinnati, Lysholm score, with preservation of ankle function based on AOFAS and FADI score at 2-years follow-up.
