Abstract:
Introduction: Isolated meniscal repair has been suggested
as one of the contributing factors in unhealed meniscal
repair. The purpose of this study was to compare the healing
rate between isolated meniscal repair and meniscal repair
with concomitant anterior cruciate ligament reconstruction
(ACLR) using a standardised assessment method after
propensity score matching.
Materials and methods: Accuracy of the Crues' grading
system for meniscal healing was validated using second-look
arthroscopy as the reference standard in 17 patients.
Propensity score matching (one-to-one) was performed
between 26 patients who underwent isolated meniscal repair
and 98 patients who underwent meniscal repair with
concomitant ACLR. Patients were matched for sex, age, side
and zone of the meniscal repair, and number of sutures.
Healing rates at one year which were evaluated with
magnetic resonance imaging (MRI) were compared between
the two groups.
Results: The sensitivity and specificity of the Crues' grading
system on multiple plane MRI for meniscal healing were
100% and 83.3%, respectively. Both the isolated meniscal
repair group and the meniscal repair with concomitant ACLR
group included 21 patients after propensity score matching.
Baseline characteristics did not differ significantly between
the two groups. The healing rate was significantly lower in
the isolated meniscal repairs group (14.3%) than in the
meniscal repair concomitant with ACLR group (47.6%,
P=0.04).
Conclusion: The healing rate for isolated meniscal repair
using a standardised MRI assessment method was inferior to
that of meniscal repair with concomitant ACLR after
propensity score matching.
