Methods to diagnose acute anterior cruciate ligament rupture: a meta-analysis of instrumented knee laxity tests

Abstract

Meta-analysis, level I.

An Extensive Evaluation of Different Knee Stability Assessment Measures: A Systematic Review

“…On the contrary, a review by Van Eck et al [16] suggests that the anterior drawer test is less sensitive (0.74) than the KT-1000 arthrometer (0.93). The literature disagreement is based on the difference of knee conditions being examined and the quality of the studies conducted.…”

“…On the other hand, objective tests can be quantitatively compared to each other in terms of their sensitivity and specificity. For example, the sensitivity and specificity of the Genucom knee analysis system have been reported to be low, at 60% and 65%, respectively [42].On the other hand, the KT-1000 sensitivity at maximum manual force is 93%, and it has a specificity of approximately 93% [16]. Despite the existing studies on the use of the hamstring-stretch reflex [26,[73][74][75], the literature lacks evidence on whether the reflex latency can be a valid objective clinical knee stability measure.…”

“…Several studies reported that clinicians use it widely in both clinics and operation theatres [16,38,54,[58][59][60]. It is performed in a supine position, with the knee at 90˝flexion and the hip at 45˝flexion.…”

“…Its sensitivity ranged from 0.50 [23] to 0.97 [16], and its specificity ranged from 0.70 [42] to 0.93 [16]. The wide range in the sensitivity and specificity was justified based on the quality of the conducted studies, the experience of the examiner and the amount of force being utilized in each test [44].…”

“…Regardless of the controversy regarding the sensitivity and specificity of the KT-1000 arthrometer, it is commonly used in research rather than in a clinical setting [8]. However, the majority of the available literature supports the KT-1000 arthrometer as being at least equal to other available knee stability measures [16,23,29,42].…”
