ABSTRACT

Aim: To determine the clinical and functional outcome of anatomical trans-portal arthroscopic ACL reconstruction with quadruple hamstring tendon auto-graft.

Study design: Prospective study

Place and duration: Orthopaedic Department, Dr. Ruth KM PFAU Civil Hospital Karachi from 1^st November 2016 and 31^st October 2019.

Methods: A total 20 male and female patients > 20 years having ACL injury confirmed by clinical examination and MRI scan were included in this study. Patients detailed demography including age, sex, causes of injury and operative time were recorded after written consent. Lachman and Pivot-shift tests were performed before surgery and during follow up period. All patients filled subjective Lysholm Knee and IKDC score pro-forma before surgery and at final follow up. In all patient arthroscopic trans-portal technique was used for ACL reconstruction with HT auto-graft.

Results: There were 17 males and 3 were females. Right knee was injured in 13(65%) cases and left knee 7(35%) cases. At final follow-up, all patients achieved full ROM, 17cases (85%) had negative Lachman, and 3cases (15%) have Grade 1 laxity. Two case (10%) had developed 1+ Pivot shift while in remaining 18 cases (90%) no Pivot-shift was present. There was significant improvement in Lysholm and IKDC score. Functional knee score in 14 cases (70%) showed good,4 cases (20%) showed excellent and 2 cases (10%) showed fair results at final follow up. Out of 20 patients, 3 patients developed complication.

Conclusion: Arthroscopic ACL reconstruction with quadrupled HT graft is a standard procedure for knee instability after ACL injury. Our study, trans-portal arthroscopic ACL reconstruction with quadruple hamstring tendon graft provide anatomical ACL reconstruction with less morbidity, stability in coronal & sagittal plan and excellent functional outcome with high knee score.
