Abstract: Introduction: Anterior cruciate ligament (ACL) reconstruction is performed to obtain pre-injury stability and to prevent early osteoarthritis of the knee in patients with ACL injury. This study was conducted to evaluate short term clinical and functional outcome of knee after trans-portal anatomic single bundle ACL reconstruction.
Methods: It was a prospective longitudinal study conducted in Department of Orthopedics, BPKIHS, Dharan, Nepal from Jan. 2017 to Sept.2017. All the patients with symptomatic ACL injury were included in the study. There were twenty patients who underwent trans-portal anatomic single bundle ACL reconstruction with quadrupled hamstring (Semitendinosus and gracilis) autograft from ipsilateral limb. The graft was fixed in femoral tunnel by an Endobutton CL and in tibia by Bioscrew. Results were assessed at 2 weeks, 6 weeks, 3 month and 6 months. Standard accelerated ACL rehabilitation protocol was followed for postoperative rehabilitation.
Results: Out of 20 patients who underwent ACL reconstruction surgery 16 were male and 4 female. Average graft size was 7±0.5mm. The longest follow up was 9 months and shortest follow up was 6 months. 18 patients could do active SLR at two weeks and 2 had extension lag of 10 degree. 19 out of 20 patients attained full range of movement at 6 weeks. Mean Preoperative Tegner Lysolm score was 63.852±1.19 and post-operative Tegner Lysolm score at 6 months was 93±3.94 with P value 0.0001. There was no infection in any case.
Conclusion: Transportal anatomical single bundle ACL reconstruction with quadrupled hamstring autograph which is fixed with Endobutton on femur and intrafix bioscrew at tibia is very good method of ACL reconstruction with predictable outcome.
