[Anterior cruciate ligament reconstruction with the peroneus longus tendon].

OBJECTIVES The aim of the study was to evaluate the results of anterior cruciate ligament (ACL) reconstruction using a peroneus longus tendon (PLT) autograft. METHODS The study included 29 patients (27 males, 2 females; mean age 30 years; range 21 to 39 years) who underwent ACL reconstruction using a PLT autograft and interference nail fixation. Fourteen patients (48.3%) also had partial meniscectomy during surgery. The results were assessed according to the Lysholm scores and the International Knee Documentation Committee (IKDC) scale at the end of at least five years of follow-up. RESULTS According to the IKDC scale, 17 patients (58.6%) were rated as normal or nearly normal, and 12 patients (41.4%) were rated as abnormal or severely abnormal. The mean Lysholm score was 83.7 (range 45 to 100), with excellent or good results in 23 patients (79.3%). Radiographic examination showed mild (n=10) or moderate (n=1) degenerative changes in the knee joint. Compared with the normal side, no flexion or extension losses occurred in the affected knees. Stability of the ACL was assessed by the Lachman test, which showed normal findings in 12 patients (41.4%), while nine patients had 1+, five patients had 2+, and three patients had 3+ anteroposterior laxity. Pivot-shift test was negative in 13 patients (44.8%); ten patients had 1+ pivot glide, and six patients had 2+ pivot shift. Two patients (6.9%) complained of mild to moderate pressure pain, paresthesia and dysesthesia at the donor site of PLT. No patient experienced ankle joint dysfunction or difficulty in sports activities due to PLT graft transfer. CONCLUSION Our data show that PLT can be an appropriate autograft source for ACL reconstruction, avoiding potential complications of autografts obtained from the knee region.
