PERONEUS LONGUS VS HAMSTRING GRAFT ACL RECONSTRUCTION - AN ANALYSIS OF FUNCTIONAL OUTCOMES

Abstract

BACKGROUND AND OBJECTIVES
ACL injury is one of the most common knee injuries and ACL reconstruction using various autografts is the gold standard treatment. Although hamstring tendon autograft has long been used, peroneus longus autograft is gaining increasing popularity. However, there are a lack of studies comparing the functional outcomes of the knee joint post ACL reconstruction using the above two grafts in the Indian population.

MATERIALS AND METHODS
The study included total of 52 patients. 26 patients in each group for ACL reconstruction with the use of PLT autograft in one group and hamstring autograft in second group. Functional outcome was assessed using IKDC score and Lysholm score for the knee joint. Clinical outcome was assessed using anterior drawer and Lachman tests. Both functional and clinical outcomes were assessed pre and post operatively at 3rd and 6th month.

RESULTS
There were no significant differences in the 3rd month and 6th month postoperative IKDC and Lysholm scores between the hamstring and peroneus longus groups. The mean diameter of the peroneus longus graft was larger than the hamstring graft, however there was no significant difference in knee stability, clinical or functional outcomes between the two groups.

CONCLUSION
Anterior cruciate ligament reconstruction with either hamstring or peroneus longus autografts produces a similar functional score (IKDC, Lysholm) at 6month follow-up. Peroneus longus graft can be considered as an alternative graft for primary ACL reconstruction.
