Hamstring Regeneration After ACL Reconstruction

Anterior cruciate ligament injuries are a common sports injury in young population.ACL rupture or tear in younger ages are managed surgically by arthroscopic ACL reconstruction.Among The graft used for it are hamstring graft (semitendinosus and gracilis) are the commonest graft chosen.).The aim of this research study is to analyse the fate of hamstring tendons (both semitendinosus and gracilis) during the time course for determinants of regeneration.Method: All patients underwent Arthroscopic ACL reconstruction were subjected to ultrasonography imaging and MRI imaging for all patients who have completed one-year postoperative period.Images were obtained at three levels and their dimensions were compared with normal side.Regrowth of the ST tendon was assessed via b-mode ultrasound at 12 months post reconstruction and MRI at 12 months Results: Out of 13 patients analysed, 9 had regeneration of hamstring tendon as evaluated by MRI and 8 showed growth as assessed by ultrasound.The average size of neo tendon was 2.5 x 5 cm (ultrasound) and 6 x 4.2 (MRI) respectively Conclusion:The study shows that there is definitive regeneration of hamstring graft after its procurement for ACL reconstruction.Hamstring grafting hence poses no serious damage to the functioning of the knee after its procurement for acl reconstruction
