Abstract:
Introduction: The diameter of the quadrupled Hamstring
graft plays a significant role in the incidence of graft failures
for ACL reconstruction. The ability to predict the graft size
pre-operatively can prepare the surgeon for alternatives in
the event of an inadequate graft diameter.
Materials and methods: We retrospectively measured the
diameter of the Semitendinosus tendon (ST) on the MRI in
all patients who underwent arthroscopic ACL reconstruction
using quadrupled Semitendinosus as their graft. We also
estimated any correlation between various anthropometric
data with pre-operative MRI based Cross Sectional Area
(CSA) of the Hamstring tendon and final graft diameter in
the South Asian population. The patients were included from
Jan 2018 - Dec 2020.
Results: The minimum CSA of ST to predict an eventual
graft diameter of 7.5mm was 10.7mm2
. The MRI based
cross-sectional area measurement showed moderate
correlation with the intra-operative graft diameter obtained.
(r=0.62, p<0.001). The intra-class correlation coefficient
between the radiologist and the surgeon was 0.82, 95% CI
(0.57, 0.92) and a p-value <0.001.
Conclusion: Pre-operative MRI can be a useful tool to
predict the graft diameter. This coupled with the
anthropometric data of the patient can be used as an adjunct
to estimate the probable graft diameter. Thus, the surgeon
can be better prepared for the surgery and can seek alternate
graft options if the graft size is deemed inadequate preoperatively.
