The GNRB((R)) is a reliable, validated arthrometer. A pressure pad
exerts 0 to 250 Newtons of pressure on the upper calf. The goal of this study was
to compare the diagnostic value of the different pressure loads that are usually
applied for the diagnosis of complete anterior cruciate ligament (ACL) tears. Our
hypothesis was that a load of 200N would be sufficient to diagnose these tears.
METHODS: A prospective comparative case-control study was performed
in 2012. One group included all the male athletes aged 15 to 21 who presented
with a complete ACL tear confirmed by arthroscopy (the study group). The control
group included male soccer players in a training center aged 15 to 19 with no
history of knee injuries (the control group). Anterior laxity was measured in
both knees by the same experienced operator using the GNRB((R)) system. The main
judgment criteria were the diagnostic values of each pressure load evaluated by
the area under the curve (AUC), from "Null" (AUC<0.5) to "Perfect" (AUC=1).
RESULTS: This study included 118 men: 64 in the study group, mean age
18.1+/-2.3-years-old, who were mainly soccer players (39/64) or rugby men (16/64)
and 54 control subjects, mean age 17.3+/-1.5-years-old. Three hyperalgesic
patients could not receive a pressure load of 250N. The mean differential laxity
was significantly higher in the control group, whatever the pressure load
(P<10(-5)). The test was "highly informative" for all loads (0.9</=AUC<1).
Analysis of the AUC revealed a diagnostic value in descending order of:
200N(0.97[0.94-1])>134N(0.97[0.93-0.99])>250N(0.96[0.93-0.99])>89N(0.95[0.90-0.99
]). CONCLUSION: The GNRB((R)) at 200N was shown to be sufficient to diagnose
complete ACL tears. Applying a pressure load of 250N does not appear to be
useful. LEVEL OF EVIDENCE: III-case-control study.
