Comparing the anatomic single-bundle versus the anatomic double-bundle for anterior cruciate ligament reconstruction: A prospective, randomized, single blind, clinical study
Abstract
Purpose The aim of this study was to compare the early
results of anatomic single bundle versus double-bundle anterior
cruciate ligament (ACL) reconstruction.
Methods We conducted a prospective randomized study of
anatomic single-bundle versus double-bundle ACL reconstruction
using the hamstring tendons of 67 patients with
unilateral ACL deficiency. The subjects were randomized into
two groups. The single-bundle group consisted of 37 patients
and the double-bundle group 30 patients.We used the following
evaluations: clinical examination, KT-1000 arthrometry,
Tegner knee score, modified Cincinnati score, Knee Injury
and Osteoarthritis Outcome Scale (KOOS), International
Knee Documentation Committee (IKDC) score. Two surgeons
performed all operations, and a blinded independent
author conducted the clinical follow-up assessments.
Results The mean follow-up period was 25.8 months. The
differences between the preoperative and postoperative clinical
examinations and the KT-1000 measurements were statistically
different in both groups (p <0.05). There were no
statistically significant differences between the groups. Tegner
knee scores, modified Cincinnati scores, and KOOS and
IKDC scores showed statistically significant improvement in
both groups (p <0.05). There were no statistically significant
differences between the groups.
Conclusions This prospective study found no difference between
the outcomes of the anatomic single-bundle and the
anatomic double-bundle ACL reconstructions.
