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.

“…Muller et al (2015) [52] reported an ICC for intra-tester reliability ranging from 0.913 to 0.999 (95% CI range: 0.319 to 1.000) and ICC for inter-tester reliability of 0.949 (95% CI: 0.542 to 1.000) for iPad software (The PIVOT software, iOS, programming language Objective-C) designed specifically for quantifying the pivot shift test. Nevertheless, Hoshino et al (2013) [56] did quantify the pivot shift test using an iPad tablet (Apple Inc., Cupertino, CA, USA). They concluded that pivot shift measurements using an iPad did provide quantification of rotational stability for ACL-deficient knees.…”

“…Similarly, the subjectivity on the amount of the applied valgus force whilst doing the test leads to difficulties in replicating the test for confirmation [33]. The specificity of the pivot shift test has been shown to be dependent on whether or not the patient is anaesthetized [56]. It ranges from 32% without to 85% with anaesthesia; this result was confirmed by Kuroda et al [34], who theorised that muscular resistance can suppress the pivot shift manoeuver.…”

Abstract:Re-injury to a recently rehabilitated or operated knee is a common occurrence that can result in significant loss of function. Knee stability measures have been used to diagnose and assess knee stability before and after rehabilitation interventions. Here, we systematically review the literature and evaluate the different anterior-posterior and rotational knee stability measures currently in use. A computer-assisted literature search of the Medline, CINAHL, EMBASE, PubMed and Cochrane databases was conducted using keywords related to knee stability measures. In a second step, we conducted a manual search of the references cited in these articles to capture any studies that may have been missed in the searched databases. The literature search strategy identified a total of 574 potential studies. After revisiting the titles and abstracts, 34 full-text articles met the inclusion criteria and were included in this review. Most articles compared knee stability measures, whilst other studies assessed their sensitivity and specificity. Several techniques and devices used to measure knee stability are reported in the literature. However, there are only a limited number of quality studies where these techniques and/or devices have been evaluated. Further development and investigation with high quality study designs is necessary to robustly evaluate the existing devices/techniques.

Anterior cruciate ligament (ACL) reconstruction aims to restore the translational and rotational motion to the knee joint that is lost after injury. However, despite technical advancements, clinical outcomes are less than ideal, particularly in return to previous activity level. A major issue is the inability to standardize treatment protocols due to variations in materials and approaches used to accomplish ACL reconstruction. These include surgical techniques such as the transtibial and anteromedial portal methods that are currently under use and the wide availability of graft types that will be used to reconstruct the ACL. In addition, concomitant soft tissue injuries to the menisci and capsule are frequently present after ACL injury and, if left unaddressed, can lead to persistent instability even after the ACL has been reconstructed. Advances in the field of biomechanics that help to objectively measure motion of the knee joint may provide more precise data than current subjective clinical measurements. These technologies include extra-articular motion capture systems that measure the movement of the tibia in relation to the femur. With data gathered from these devices, a threshold for satisfactory knee stability may be established in order to correctly identify a successful reconstruction following ACL injury.

Quantitative evaluation of the pivot shift by image analysis using the iPad

Abstract: Although some technical corrections, such as testing manoeuvre and recording procedure, are needed to improve the image data sampling using the iPad application, the potential of the iPad application to classify the pivot shift was demonstrated.
