“…Previous work by the authors of this study and others have demonstrated lateral meniscus pathology to be a key factor contributing to a more explosive pivot-shift as measured by various quantitative assessments. 2,3 Further, our group has demonstrated more chronic ACL tears to be associated with a greater risk of a high-grade pivot-shift by manual assessment, 4 and this study confirms that finding with a more quantitative measurement methodology.…”

Control of anterolateral knee laxity has always been a major goal of anterior cruciate ligament (ACL) reconstruction. The recent focus on the anatomy of the anterolateral knee and new studies demonstrating decreased graft failure risk with the additional of lateral procedures to intra-articular ACL reconstruction have given these procedures new relevance. A key question that drives indications is which patients benefit the most from these procedures. Those patients with increased rotational knee laxity, particularly in the absence of a repairable meniscus injury, may be good candidates. ACL injury chronicity, bony anatomy, concomitant anterolateral injury, and other factors all contribute to increased anterolateral knee laxity. This high laxity population is ideal for evaluation of the effectiveness of new methods to control knee laxity and improve outcomes of isolated intra-articular ACL reconstruction.

“…25,29,32 Whereas anterior tibial translation has been shown to be significantly higher in ACL injuries with medial or lateral meniscal tears (3.7 vs 2.7 mm, respectively), 27 tibial acceleration was influenced by only lateral meniscal tears (2.1 ± 1.1 vs 1.2 ± 0.7 m/s 2 , respectively). 12 The present study demonstrated that anatomic ACLR with appropriate meniscal repair resulted in excellent restoration of rotatory laxity as measured by the pivot-shift test, as well as acceptable PROs, at 24-month follow-up.…”

“…25 Individualized treatment for patients with ACL injuries is important, and the QPS may help direct attention to additional soft tissue injuries, ensuring complete restoration of rotatory knee stability, as shown in this study. 12,25,27 Moreover, in 1 case, the pivot-shift test was helpful in confirming intraoperative knee stability. In this patient, the QPS was equal at time zero postoperatively compared to preoperative measurements, which led to an investigation into femoral fixation with fluoroscopy.…”

“…39 When discussing rotatory knee stability, a patient-specific individualized treatment strategy based on the injured structures and degree of instability must be considered. 12,27 An individualized anatomic approach may be the key to optimize long-term PROs. In the literature, a broad variety of soft tissue injury patterns and bony morphologies has been described to influence rotatory instability, 16,28,29,31,32 but a threshold for high-grade rotatory instability for which additional procedures are required is still lacking.…”

Background: The pivot-shift test has become more consistent and reliable and is a meaningful outcome measurement after anterior cruciate ligament reconstruction (ACLR). Purpose/Hypothesis: The purpose of this investigation was to assess patient-reported outcomes (PROs) and the quantitative pivot shift (QPS) preoperatively, at time zero immediately after anatomic ACLR, and after 24 months as well as the relationship between PROs and the QPS. It was hypothesized that anatomic ACLR would restore rotatory stability measured by the pivot-shift test and that QPS measurements would be positively correlated with PROs. Study Design: Cohort study; Level of evidence, 2. Methods: The ACL-injured and contralateral uninjured knees from 89 of 107 (83.2%) enrolled patients at 4 international centers were evaluated using a standardized pivot-shift test. Tibial acceleration was assessed with an inertial sensor, and lateral compartment translation was measured using an image analysis system preoperatively, at time zero immediately postoperatively, and at follow-up after 2 years. PROs were assessed at 12 and 24 months postoperatively with the International Knee Documentation Committee (IKDC) subjective knee form, Cincinnati Knee Rating System (CKRS), Marx activity rating scale, and activity of daily living score (ADLS). Results: The mean patient age at surgery was 27 years (range, 15-45 years). A positive pivot shift preoperatively (side-to-side difference in tibial acceleration, 2.6 ± 4.0 m/s2; side-to-side difference in anterior tibial translation, 2.0 ± 2.0 mm) was reduced at time zero postoperatively (side-to-side difference in tibial acceleration, –0.5 ± 1.3 m/s2; side-to-side difference in anterior tibial translation, –0.1 ± 1.0 mm). All PROs improved from preoperatively to final follow-up at 24 months: from 56.5 to 85.5 points for the IKDC ( P = .0001), from 28.8 to 32.4 points for the CKRS ( P = .04), from 11.2 to 7.9 points for the Marx ( P < .0001), and from 75.7 to 91.6 points for the ADLS ( P < .0001). Neither preoperative nor time zero postoperative rotatory laxity assessed by the pivot-shift test correlated with PROs at 24-month follow-up. A graft retear was observed in 4 patients (4.5%) within 2 years of follow-up. Conclusion: Anatomic ACLR resulted in significantly improved and acceptable PROs at 2-year follow-up and a low failure rate. Anatomic ACLR restored QPS measurements of anterior tibial translation and tibial acceleration to those of the contralateral knee immediately after surgery while still under anesthesia, but there was no correlation between the QPS preoperatively or at time zero after ACLR and PROs at 2-year follow-up.

“…The disadvantage of ETS is that it is cumbersome and unable to be easily used outside of a laboratory or clinical-based setting. Recently, however, a more clinically friendly device that measures knee kinematics using only two electromagnetic sensors (on the thigh and shank) has been reported [23,24]. This compact ETS also enables quantitative evaluation of the pivot shift test pre-and post-anterior cruciate ligament (ACL) reconstruction.…”

Introduction As the demand for rehabilitation in orthopaedics increases, so too has the development in advanced rehabilitation technology. However, to date, there are no review papers outlining the broad scope of advanced rehabilitation technology used within the orthopaedic population. The aim of this study is to identify, describe and summarise the evidence for efficacy for all advanced rehabilitation technologies applicable to orthopaedic practice. Methods The relevant literature describing the use of advanced rehabilitation technology in orthopaedics was identified from appropriate electronic databases (PubMed and EMBASE) and a narrative review undertaken. Results Advanced rehabilitation technologies were classified into two groups: hospital-based and home-based rehabilitation. In the hospital-based technology group, we describe the use of continuous passive motion and robotic devices (after spinal cord injury) and their effect on improving clinical outcomes. We also report on the use of electromagnetic sensor technology for measuring kinematics of upper and lower limbs during rehabilitation. In the home-based technology group, we describe the use of inertial sensors, smartphones, software applications and commercial game hardware that are relatively inexpensive, user-friendly and widely available. We outline the evidence for videoconferencing for promoting knowledge and motivation for rehabilitation as well as the emerging role of virtual reality. Conclusions The use of advanced rehabilitation technology in orthopaedics is promising and evidence for its efficacy is generally supportive.
