Abstract
Introduction
The tear of anterior cruciate ligament (ACL) is the most common ligamentous injury and is mostly related to sports activities. The approach to ACL tear has undergone several changes during the last four decades. Currently, there is no consensus on the optimal graft fixation technique especially at the tibial site.
Aims and Objectives: Evaluation of quadrupled hamstring graft as ACL substitute and comparison of the two common modalities of graft fixation at tibial attachment, namely- Bioscrew technique and Tightrope technique.
Study design: Retrospective study
Materials And Methods
30 ACL deficient knees (aged between 20yrs -50yrs) were included in the study conducted at the Government Institute of Medical Sciences, Greater Noida, UP and were followed up to 6 months. Standard arthroscopic ACL reconstruction technique and ipsilateral quadrupled hamstring tendon graft were used. 15 cases each underwent ACL reconstruction by Bioscrew and Tightrope fixation on the tibial side. The fixation modality groups were chosen randomly using computer software. Standard conservative ACL rehabilitation protocol was followed and return to full activities was started at 6 months. Clinical evaluation was done pre-operatively and post-operatively at 2 weeks, 8 weeks, 14wks and 6 months. CT evaluation of tibial tunnel diameter was done at 2 weeks, 3 months and 6 months. Final grades were given to each knee at the 6th month follow-up on the IKDC subjective knee evaluation score and modified Lysholm’s knee score and the results were compared with pre-operative data statistically.
Results
and Discussion: There was no significant difference in knee stability and functional outcomes between the Bioscrew and Tightrope groups. No significant tibial tunnel widening was observed between the two groups and was comparable up to the 14th week. Still after that, in the Tightrope group, widening was more than in the Bioscrew group particularly, at the midway. Lysholm’s score was comparable at 6 months in both groups.
