[Treatment of anterior cruciate ligament injury with peroneus longus tendon].

OBJECTIVE

To evaluate the effects of anterior cruciate ligament reconstruction with peroneus longus tendon and observe the clinical outcomes of ankle joint after the resection of peroneus longus tendon.

METHODS

From January 2006 to December 2009, 35 patients with anterior cruciate ligament injuries were recruited to undergo surgical procedures. There were 30 males and 5 females with an average age of 31.8 years (range: 21 - 56). All anterior cruciate ligament reconstructions underwent arthroscopy. All ligaments were reconstructed with peroneus longus tendon and fixed with absorb screw. The post-operative assessments included the followings:clinical evaluations, Lysholm knee score, KT-3000 arthrometer evaluation and the American Orthopedic Foot and Ankle Society ankle-hindfoot scale AOFAS).

RESULTS

All cases were followed up for an average follow-up period of 15 months (range: 12 - 24). The healing time was 6 - 15 weeks.according to the Lysholm knee score, their outcomes were excellent (n = 25), good (n = 6), fair (n = 3) and poor (n = 1). The average score was 97.2 (range: 60 - 100). The rate of excellent and good was 88.6%; according to the KT-3000 arthrometer evaluations, the outcomes were normal (n = 28), nearly normal (n = 4), abnormal (n = 2) and poor (n = 1). Preoperatively, the average anterior displacement was 11.59 ± 1.25 mm and the average anterior displacement at final follow-up 1.76 ± 1.83 mm. The average AOFAS score was 96.3 (range: 84 - 100). Lysholm knee score and KT-3000 arthrometer evaluation had statistical differences (P < 0.05) while AOFAS score showed no difference (P > 0.05).

CONCLUSION

Peroneus longus tendon can be a good substitute of anterior cruciate ligament reconstruction. And its resection has no major influence for ankle joint.
