Conditions
Brief summary
Injury to the Infrapatellar branch of the saphenous nerve (IPBSN) may result uncomfortable or even painful sensory changes to the skin over the front of the knee. Anterior cruciate ligament (ACL) reconstruction in an established effective procedure in symptomatic instability. There are two main techniques for the surgery. A 4 strand hamstring graft is commonly performed in Australia. The nerve or its branches run very closely to or through the site of incision for hamstring harvest or the main alternative procedure harvesting patellar ligament and bone. Injury to the IPBSN or its branches is common in ACL surgery. Anatomical dissection studies have recommended that oblique or horizontal incisons may result in a lower rate of nerve injury. The current standard technique is a vertical incision. There has been a clinical outcome study investigating obliquity of incision in patellar ligament grafts which demonstrated a relationship with nerve injury. There has not been an clinical outcome study investigating obliquity of incision and nerve injury in hamstring grafts.
Interventions
Hamstring harvest incision orientation of either oblique or horizontal in elective ACL reconstruction.
The surgery takes approximately 1- 2 hours and surgery is performed at a variable time after injury depepnding on indication.
