Abstract:
Introduction: Pre-operative identification of patients with
inadequate hamstring graft for anterior cruciate ligament
reconstruction is still a subject of interest. The purpose of
this study is to correlate dimension of a harvested
dimensions graft with patient physical anthropometric
variables.
Materials and methods: This cohort study included 280
patients (male = 226, female = 54) scheduled for primary
anterior cruciate ligament (ACL) reconstruction.
Interrelationships between quadruple semitendinosus (ST)
graft and anthropometric parameters (age, sex, height,
weight, and BMI) were assessed using Pearson Correlation
test and regression analysis. Difference among gender was
analysed using Mann Whitney and t test. The observed graft
diameter was also compared with the literature using Bland
– Altman plot.
Results: Mean age of cohort was 29 years (range, 17-50
years), mean height was 1.69m (range, 1.6-1.9m), mean
weight was 75 kg (range, 50-116kg) and mean BMI was
26kg/m2 (range 16.65-40.40kg/m2). Mean quadruple length
of harvested ST graft was 7cm (7.1±0.6 cm, range, 5.6-
8.8cm) and mean diameter was 8mm (8.2±0.8mm, range,
6.5-10mm). Only height and weight were significantly
correlated with graft length and diameter in both sex (p value
<0.05). Female, compared to male, had significantly smaller
(p<0.0001) and thinner graft (p<0.0001). There was a strong
agreement between the literature and our observed graft
diameter, but with an overestimated graft diameter in 18.5%
of the cases.
Conclusion: Among anthropometric parameter, only height
and weight had moderate positive correlation with graft
diameter. Males had longer and wider ST graft in contrast to
age-matched female group.
