A modified oblique incision in hamstring tendon graft harvesting during ACL reconstruction

Abstract Background During anterior cruciate ligament (ACL) reconstruction, different methods of harvesting hamstring tendon may lead to degrees injury the inferior patellar branch saphenous nerve (IPBSN). Most recent studies in literature suggest that classic oblique incision (COI) can reduce incidence IPBSN injury. We proposed a modified (MOI) and compared it with COI terms resulting levels sensory loss clinical outcome. Methods Patients ACL admitted our hospital from April 2015 July 2019 were randomly selected included study. Thirty patients underwent harvest tendons, other 32 MOI. The pin prick test was performed detect sensation at 2 weeks, 6 months, 1 year after operation. Digital photos region hypoesthesia area taken, then, computer software (Adobe Photoshop CS6, 13.0.1) used calculate hypoesthesia. length knee joint functional score also recorded. Results At final follow-up, MOI 33.3% 9.4%, areas paresthesia 26.4±2.4 cm 9.8±3.4 respectively. There no significant difference or between two groups. Conclusion significantly risk IPBSN, hypoesthesia, high subjective satisfaction. Therefore, COI, is better method tendons reconstruction.
