“…Once standard cutoff points are validated in vivo, these thresholds can then be used to calculate and compare the diagnostic accuracy and reliability for varus and valgus stress radiography between studies with greater confidence. Franklin [7] KT-1000 No significant difference between KT-1000 and stress radiography Stäubli [45] KT-1000 Both KT-1000 and stress radiography are diagnostic for chronic ACL-deficient knees…”

“…One reason for this is the varying stress techniques and forces used between studies. For example, although Franklin et al [7], Stäubli and Jakob [45], and Lerat et al [30] all compared stress radiography for the diagnosis of ACL injury to the KT-1000, stress techniques varied. Franklin et al use the quadriceps contraction technique at 133 N to 178 N, Stäubli et al used the KT-1000 at 89 N, and Lerat et al used a 9-kg free weight.…”

“…The stress radiography techniques and devices described in the literature varied by the plane of stress and therefore the ligament(s) isolated ( 47], manual force [6,12,13,32,40,44,46], hydraulic force [17][18][19], S-type load cell [25,26], a constant-tension spring [48], and the dynamic stress test using active muscle contraction [1,7,21]. A total of 16 unique stress techniques were described across all studies included in this review (Table 3).…”

“…Three of five studies comparing stress radiography with the KT-1000 or KT-2000 (MEDmetric Corporation, San Diego, CA, USA) for the diagnosis of AP instability concluded that stress radiography is superior, whereas the other two studies showed excellent but equivalent diagnostic ability [7,14,29,31,45]. For diagnosis of ACL injury, stress radiography correlated with results of the pivot shift test but not the Lachman's test [15], was equivalent to the GNRB computerized arthrometer [2], and offered greater sensitivity but similar specificity to the Rolimeter [34].…”

“…Some investigators choose landmarks which evaluate translation in one knee compartment (i.e., medial or lateral), while others select midline landmarks which represent overall tibial translation. The lateral knee compartment has consistently shown higher anterior laxity in both normal and injured knees, and investigators have found better reliability in measuring the medial compartment [9][10][11][12].…”

Arthrometry and stress imaging are useful clinical tools for the objective assessment of anterior cruciate ligament (ACL) integrity. They are most frequently used for the diagnosis of a complete ACL tear when other workup is equivocal, in conjunction with history and clinical exam findings. Other applications include the diagnosis of partial ACL tears, injury prognosis, and post-operative monitoring. However, further studies are needed to validate these uses. Many different devices and techniques exist for objective examination, which have been compared in recent literature. Reliability and validity measures of these methods vary, and often depend upon examiner familiarity and skill. The KT series of devices is the current gold standard for arthrometry, although the newer robotic GNRB device shows promising early results. Newer methods of data interpretation have been developed for stress imaging, and portable technology may impact this field further.

Kinematics measured during a short arc quadriceps knee extension exercise were compared in the knees of functionally unstable ACL-deficient patients, these patients' uninjured knees, and uninjured control subjects' knees. Cine phase contrast dynamic magnetic resonance imaging, in combination with a model-based tracking algorithm developed by the authors, was used to measure tibiofemoral kinematics as the subjects performed the active, supine posture knee extension exercise in the terminal 30 degrees of motion. Two determinants of tibiofemoral motion were measured: anterior/posterior location of the tibia relative to the femur, and axial rotation of the tibia relative to the femur. We hypothesized that more anterior tibial positioning, as well as differences in axial tibial rotation patterns, would be observed in ACL-deficient (ACL-D) knees when compared to uninjured knees. Multifactor ANOVA analyses were used to determine the dependence of the kinematic variables on (i) side (injured vs. uninjured, matched by subject in the control group), (ii) flexion angle measured at five-degree increments, and (iii) subject group (ACL-injured vs. control). Statistically significant anterior translation and external tibial rotation (screw home motion) accompanying knee extension were found. The ACL-D knees of the injured group exhibited significantly more anterior tibial positioning than the uninjured knees of these subjects (average difference over extension range ¼ 3.4 AE 2.8 mm, p < 0.01 at all angles compared), as well as the matched knees of the control subjects. There was a significant effect of interaction between side and subject group on A/P tibial position. We did not find significant differences in external tibial rotation associated with ACL deficiency. The changes to active joint kinematics documented in this entirely noninvasive study may contribute to cartilage degradation in ACL-D knees, and encourage more extensive investigations using similar methodology in the future. ß
