Saphenous nerve injury during harvesting of one or two hamstring tendons for anterior cruciate ligament reconstruction☆

چکیده
OBJECTIVE The aim of this study was to assess whether harvesting of two hamstring tendons (semitendinosus and gracilis) has the same rate of nerve injury as harvesting of the semitendinosus tendon alone, used as a triple graft. METHODS Changes in sensitivity relating to injury of the infrapatellar branch of the saphenous nerve were evaluated in 110 patients six months after they underwent anterior cruciate ligament (ACL) reconstruction using hamstring tendons. They were divided into two groups: one in which only the semitendinosus was used and the other, the semitendinosus and gracilis. RESULTS The group in which only the semitendinosus was used as a graft presented a nerve injury rate of 36.1%. In the group in which the semitendinosus and gracilis tendons were used, 58.1% of the patients presented altered sensitivity. In the general assessment on all the patients, the nerve injury rate was 50.9%. CONCLUSION Harvesting the semitendinosus alone and using it in triple form is a viable option for ACL reconstruction and may give rise to fewer nerve injuries relating to branches of the saphenous nerve.

Background: Injury to the infrapatellar branch of the saphenous nerve (IPBSN) is common after arthroscopic ACLreconstruction with hamstring tendon autograft, as reported in up to 88% of the cases. Due to close relationshipbetween the IPBSN with pes anserine tendons insertion skin incision may sever IPBSN while harvesting gracillis andsemitendinous tendons. As the IPBSN course at the anterior of...

BACKGROUND It was suggested that the direction of incision for medial hamstring tendons harvesting influences the incidence of injury to the infrapatellar branch of the saphenous nerve (IPBSN), a common complication following arthroscopically-assisted anterior cruciate ligament reconstruction (ACLR). OBJECTIVES The main purpose of current study was to compare the incidence of IPBSN injury bet...

Electromechanical delay of the knee flexor muscles is impaired after harvesting hamstring tendons for anterior cruciate ligament reconstruction.
BACKGROUND Changes in electromechanical delay during muscle activation are expected when there are substantial alterations in the structural properties of the musculotendinous tissue. In anterior cruciate ligament reconstruction, specific tendons are being harvested for grafts. Thus, there is an associated scar tissue development at the tendon that may affect the corresponding electromechanical...

Rupture of the anterior cruciate ligament (ACL) is a common injury. The management of such injuries has been much debated and surgical reconstruction with an autograft is a popular option. Here the evidence on the use of two popular candidates (the patellar tendon and hamstring tendons) are compared in an attempt to discover the superior or to gain an indication of factors that may influence th...
