Summary: Ankle joint instability after acute lateral ankle sprain is an important factor for treatment decisions, but the use of ankle joint mechanical instability as a criterion for clinical decisions is unclear. This study examined the reliability and validity of an Automated Length Measurement System (ALMS) in ultrasonography for real-time measurement of anterior talofibular distance. The results show that ALMS has excellent reliability, comparable measurement values to manual methods, and the ability to detect differences in joint distances. ALMS can standardize and simplify ultrasonographic measurements without human error in clinical applications.

Summary: This study compared the reliability and accuracy of anterior translation distance between junior and senior examiners in the traditional anterior drawer test (ADT), and evaluated the diagnostic abilities of traditional ADT and a novel modified ADT (supported ADT). The results showed that supported ADT had higher inter-examiner reliability and better diagnostic accuracy for junior examiners compared to traditional ADT.

Summary: The modified anterior drawer test (MADT) showed higher sensitivity and accuracy in detecting ACL ruptures compared to traditional tests such as the anterior drawer test, Lachman test, and pivot shift test. MADT could be a valuable alternative diagnostic tool for ACL tears, improving the diagnosis when combined with other clinical information.

Summary: Lateral ankle sprains are a common injury that often involves the anterior talofibular ligament (ATFL). Evaluating joint laxity in ankle sprains has been subjective, but the Mobil-Aider arthrometer provides a reliable and valid method for assessment. This study found significant differences in anterior translation between healthy ankles and ankles with grade 1 and 2 sprains, highlighting the usefulness of the arthrometer in quantifying orthopaedic examination.

Summary: The magnitude of talar cartilage deformation after a static loading protocol in patients with chronic ankle instability (CAI) is associated with mechanical and sensorimotor outcomes. Targeting mechanical instability and poor balance in those with CAI through intervention strategies may improve how the talar cartilage responds to static loading conditions.

Summary: This study compared the accuracy of an automatic knee arthrometer (AKA) to the KT-2000 arthrometer in measuring knee laxity after ACL ruptures. The results showed that AKA had smaller variance in measurements and better consistency between examiners. Compared to KT-2000, AKA had a higher diagnostic value in determining knee laxity.

Summary: The study aimed to evaluate the changes in talar and subtalar cartilage in patients with chronic lateral ankle instability who underwent ATFL repair or reconstruction, comparing them with asymptomatic controls. The results showed that neither ATFL repair nor reconstruction could prevent further degeneration of talar and subtalar cartilage, but they did not impact ankle function and activity levels in the short term.

Summary: The study found that the inclination angle of the posteroinferior talar facet was significantly more plantarly orientated in patients with chronic ankle instability compared to healthy controls. This suggests that a more plantarly and valgus orientated posteroinferior talar facet may be associated with chronic ankle instability.

Summary: The study found that patients with anterior shoulder instability and excessive joint laxity had wider Hill-Sachs lesions and more off-track lesions than those with normal joint laxity, despite no significant difference in glenoid bone defects. However, these differences in Hill-Sachs lesions did not affect the functional outcomes between the groups.

Summary: This study measured talar displacement using ultrasound during an anterior drawer test with a Telos device. The results showed that talar displacement was lower in the group with a history of ankle sprain compared to the control group. The ultrasound-based quantitative anterior drawer test using a Telos device was found to be more accurate in detecting reduced ankle joint mobility than the conventional stress X-ray.

Summary: The biggest challenge in the treatment of acute ankle sprain is the uncertainty of the prognosis. In this study, a new classification based on clinical criteria was proposed to determine the prognosis of ankle sprain. The classification, which includes evaluation of gait capacity, inspection and palpation, as well as ankle pivot test, proved to be a simple and reliable tool.

Summary: In this in vitro study, it was found that a triple-strand reconstruction with a dMCL graft could restore native external rotation, while a double-strand reconstruction without a dMCL graft could not. Placing the sMCL graft isometrically on the medial epicondyle in the reconstruction restored valgus rotation across the arc of knee flexion, while placing it more posteriorly resulted in slackening with knee flexion.

Summary: The study evaluated the clinical outcomes of a one-step procedure combining ACL reconstruction and partial meniscus replacement using a polyurethane scaffold in symptomatic patients with previously failed ACL reconstruction and partial medial meniscectomy. Clinical assessment showed improvement at 2- and 5-year follow-ups, but MRI evaluation suggested inconsistent integration of the scaffold.

Summary: This study evaluated the midterm follow-up results of lateral meniscal allograft transplantation (MAT) performed with a soft tissue fixation technique after capsulodesis. The results demonstrated high graft survivorship, significant improvement in pain and function, and maintenance of joint space width and alignment. Thus, MAT is an effective reconstructive procedure for treating symptomatic postmeniscectomy syndrome.

Summary: The effectiveness of different conservative interventions for acute hamstring injuries in athletes is unclear. This study compared the effects of various conservative interventions on the time to return to sport or full training and reinjury rates. The results showed that no single intervention or combination of interventions demonstrated superior outcomes in terms of faster recovery time or reduced risk of reinjury.

Summary: The purpose of this study was to perform an in vivo kinematic analysis of isolated modified Lemaire lateral extra-articular tenodesis (LET) to assess its ability to improve the stability of anterior cruciate ligament (ACL) deficient knees. The results showed that the modified Lemaire LET significantly reduced rotational and anteroposterior instability of the knee, leading to improved knee function and clinical outcomes.

Summary: An ACL tear, a severe sports injury common among young athletes, is poorly understood, particularly regarding the role of external rotation in the injury mechanism. This study used a finite element model to evaluate knee kinetics and found that combined knee valgus, flexion, tibial external rotation, and high axial load result in higher ACL stress and strain. The study highlights the significance of external rotation and the need for further research in this area. The findings contribute to the prevention, diagnosis, and treatment of ACL injuries.

Summary: There is no consensus on how to measure shoulder joint laxity and the reported results lack systemization for shoulder arthrometer devices. This systematic review aims to summarize the results of available shoulder arthrometers in measuring glenohumeral laxity. The review includes 23 studies comprising 1162 shoulders, and the results show substantial heterogeneity in glenohumeral laxity values, mainly influenced by the arthrometer used and testing conditions, potentially leading to inconsistent results and impacting diagnosis and treatment decisions.
