“…The developers cited measurement error, cost, time, and limitation to the anteroposterior plane in their reasoning. Wiertsema et al were also critical, finding the KT-1000 inferior to the Lachman test in both intra-rater (ICC = 1.0 vs. 0.47) and inter-rater (ICC = 0.77 vs. 0.14) reliability, even with experienced KT-1000 users [43]. The few other published reliability measures vary, with intra-rater reliability ranging from 0.67 to 0.99 and inter-rater reliability ranging from 0.65 to 0.92 [37,40,44].…”

“…Alone, the diagnostic value of laximetry appears comparable to classic exam maneuvers such as the Lachman's or pivot-shift tests, but the combination of both measures is superior [5,28,43,86,87]. Some literature suggests that this combination exceeds the diagnostic abilities of MRI, thus potentially obviating the need for the added time and cost of advanced imaging [5,28].…”

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.

“…Compared with physical examination, stress radiographs provide a quantifiable and retrievable record of instability. Physical examination alone has often been reported to be inaccurate, subjective, and poorly reproducible for assessing anterior knee laxity [3,23,49,53]. Clinician experience, a patient's pain, tolerance of the examination, and concurrent ligamentous injuries may skew physical examination interpretation, detracting in certain situations from its clinical use [22,25,27].…”

“…This was graded as 1+ (0-5 mm of displacement), 2+ (5-10 mm of displacement), or 3+ (greater than 10 mm of displacement) [34]. The test was only performed by a single surgeon, so we could not evaluate interobserver variability; however, the test has previously been identified as having high reported interobserver reliability of 0.77 in a prior report [35]. We considered either 2+ or 3+ as indicating ACL instability.…”

Background TKA with retention of the anterior cruciate ligament (ACL) may improve kinematics and function. However, conflicting reports exist concerning the prevalence of intact ACLs at the time of TKA. Questions/purposes Therefore, we asked: (1) what was the ACL status at TKA; (2) what was the sensitivity and specificity of the Lachman test; (3) did MRI ACL integrity correlate with intraoperative observation; (4) did MRI tibial wear patterns correlate with ACL integrity; and (5) did ACL status depend on age or sex? Methods We evaluated 200 patients for ACL integrity at the time of TKA. All patients underwent a Lachman test under anesthesia. Intraoperatively, the ACL was characterized as intact, frayed, disrupted, or absent. In 100 patients, MRIs were performed, from which the ACL was graded as intact, indeterminate, or disrupted, and the AP location of tibial wear was categorized. Results The ACL was intact in 155 patients (78%). The Lachman test alone had poor diagnostic ability. The MRI predicted a tear, but we observed two ACLs with indeterminate status that were disrupted. All knees with anterior wear on the medial tibial condyle had an intact ACL (n = 45), and all knees with posterior wear on the medial tibial condyle had a disrupted ACL (n = 8).Conclusions Although the Lachman test alone had poor sensitivity, when combined with MRI they together provide a sensitivity of 93.3% and specificity of 99%, which we believe makes these reasonable tests for assessing ACL status in the arthritic knee.
