Internal saphenous nerve injury as a complication In primary cruciate ligament plasty Previous Autograft (Hamstring) Comparison between vertical and oblique incision

Abstract

INTRODUCTION: The internal saphenous nerve is a
sensory branch of the femoral nerve, which at the level of the knee
gives off an infrapatellar branch (RIP) that innervates its face
anterior and a terminal branch (RTS) that innervates
sensitive to the antero and posteromedial sector of the leg. In
arthroscopic surgery, either by the portals used or by
skin incisions for autograft harvesting, both
branches can be injured and generate disorders in the
sensitivity of different intensity.
OBJECTIVE: To assess the incidence of nerve injury
internal saphenous, its impact during the postoperative period,
placing special emphasis on reconstructive techniques that
use hamstring autografts.
MATERIALS AND METHOD: Between January 2018 and
February 2019, 15 cruciate ligament repairs were performed
anterior with Hanstring autograft with vertical incision
compared with 15 patients who underwent plastic surgery
anterior cruciate ligament with Hanstring autograft
with oblique incision the age group included patients
between 20 and 50 years. The functional scales of
Lysholm. Range of motion and pain were measured at 1, 3, 6
and 12 months.
RESULTS: The average follow-up was 1 year (3
– 11 months) for the cruciate ligament plasty group
anterior with Hanstring autograft with oblique incision
and
1 year (4 – 11 months) for the ligament repair group
Anterior crossover Hanstring autograft with incision
vertical. There were no significant differences in terms of
functional scales in the medium term.
CONCLUSION: According to our findings, it is suggested the
oblique incision instead of the traditional vertical incision
when the hamstring tendons are pulled in the
arthroscopic ACL reconstruction with autograft of
hamstrings.
