Abstract

Objective The present study aimed to compare the oblique and vertical incisions in hamstring tendon harvesting in anterior cruciate ligament (ACL) reconstruction and in infrapatellar branch injury of the saphenous nerve.

Methods The present study was conducted at a tertiary referral center for 12 months. Patients with an indication of reconstruction of ACL tear were included in the study, who were then randomized into two groups (vertical [VG] and oblique [OG] groups). After excluding a few cases, 92 patients were eligible for further analysis (VG: n= 44; OG: n = 48). They were followed-up for 9 months after the surgery, and loss of sensation over the knee and over the proximal aspect of the operated leg was recorded.

Results The mean lengths of the incisions were 27 mm and 38 mm for the OG and VG groups, respectively. The total rate of hypoesthesia was 40% (27 patients). A total of 12 (25%) and 25 patients (56.8%) on the OG and VG groups, respectively, reported hypoesthesia symptoms. The presence of hypoesthesia in patients in the VG group was two times higher than in the OG group. No statistical correlation was observed between the nerve injury and age, gender, education, and delay from injury to reconstruction.

Conclusion Oblique incision, which showed lower risk of nerve damage, might be more recommended for graft harvesting. Patients who underwent reconstruction of the ACL in the OG group had a lower incidence of peri-incisional hypoesthesia when compared to those in the VG group.
