The clinical research on using the anterior half of the peroneus longus tendon as an autograft source / 中华骨科杂志

ABSTRACT

Objective To evaluate availability and outcomes of using anterior half of the peroneus longus tendon (AHPLT) in knee ligament reconstruction as an autograft source.Methods From July 2007 to January 2008,100 patients with knee ligament injuries were recruited in this study.There were 33 males and 67 females aging from 16 to 62 years (mean,32.3 years).49 cases had undergone medial patellofemoral ligament reconstruction,19 cases multiligament reconstruction,18 cases double-bundle posterior cruciate ligament (PCL) reconstruction and 14 cases double-bundle anterior cruciate ligament (ACL) reconstruction.AHPLT was used as sole (49 cases) or part (51 cases) of reconstruction materials.One-incision or two-incision striping techniques were adopted to harvest AHPLT.Ligaments were fixed with screws.Post-operative assessments included Kujala knee score,Lysholm knee score,Marx knee score,International Knee Documentation Committee (IKDC) subjective evaluation form and objective evaluation grade,the Foot and Ankle Disability Index (FADI) and the American Orthopedic Foot and Ankle Society (AOFAS) scale.Results 92 cases were followed up for more than 24 months.Postoperative Kujala score,IKDC subjective score,Lysholm score and Marx score were improved significantly in all four groups of patients.According to IKDC objective evaluation grade,the number of patients reaching Grade A (normal) or Grade B (near-normal) in multiligament,PCL and ACL reconstruction were 17,15 and 12,with an excellent rate of 89.5％ (17/19),93.7％ (15/16) and 100％ (12/12),respectively.Preoperative and postoperative AOFAS scores were 97.4±2.0 and 97.2±1.6,respectively,while the FADI scores preoperatively and postoperatively were 96.8±2.2 and 96.9±2.5,respectively.These results had no statistical significance.No signs of peroneal nerve injury or peroneus longus tendon rupture was found.Conclusion It is acceptable to use AHPLT as an autograft due to its feasibility to harvest,good clinical outcome,and low rate of donor site morbidity at a minimum of two-year follow-up.
