Abstract

Aim: The aim of the present study to evaluate the anterior cruciate ligament reconstruction
using a combination of autograft and allograft tendon
Methods: Twenty Total 44 patients were included in this study and divided into two equal
groups 22 patients. Out of 44 patients, 22 were undergoing for auto graftsand 22 patients for
hybrids process. These 22 patients were matched by age (within 1 year) and sex with 22
patients who underwent hamstring autograft ACL reconstruction during the same time period.
Collected data included graft size, patient demographics, intraoperative findings, femoral
tunnel drilling technique, and patient-reported outcome scores (International Knee
Documentation Committee [IKDC],13 Knee injury and Osteoarthritis Outcome Score
[KOOS],14 and Marx activity score 15) prior to surgery.
Results: The final graft size was noted to be larger in the hybrid group (9.5+ 0.6 mm) than
the autograft group (8.4 ±0.9 mm) (P < .001). 5 month postoperatively, no significant
differences in KOOS, IKDC, or Marx activity score were noted between the hybrid and
autograft groups (Table 5 and 6). Both groups demonstrated significant improvements in
KOOS and IKDC compared with preoperative values (P < .001). Revision ACL surgery was
performed in 5 patients in the hybrid group (22.73%) and 2 patients in the autograft group
(9.9%).
Conclusion: Patients who undergo ACL reconstruction with hybrid hamstring grafts and
hamstring autografts report similar patient-reported outcome scores at 15 months
postoperative. Further work is required to investigate potential increased risk of revision ACL
reconstruction
