Summary: This study aimed to evaluate the diagnostic accuracy of a new test for identifying Achilles tendinopathy. Using an observational study design, 70 patients with unilateral Achilles tendinopathy were tested using David's test. The results showed that asymmetry of Kager's fat pad in relation to the Achilles tendon during passive dorsiflexion is strongly indicative of tendinopathy, with a sensitivity of 85.71% and a specificity of 100%.

Summary: The study found that tendon structure, specifically echo-types III and IV in the patellar tendon (PT) and echo-type III in the Achilles tendon (AT), may be risk factors for musculoskeletal injuries in combat soldiers. Participants with PT echo-type III + IV > 10%or AT echo-type III > 8.5% had the highest risk of being injured during the course. High-risk soldiers/athletes should undergo intervention programs to prevent subsequent injury.

Summary: The study aimed to simplify the measurement of Achilles tendon curvature by reducing the number of markers while maintaining high accuracy. Results showed that using only 30% to 50% of the marker set can maintain high accuracy in determining AT length and strain, which is useful for practical applications.

Summary: Prior to inserting into bone, healthy tendons experience impingement from nearby bony structures. Excessive impingement is associated with tendon pathology. This study found that passive dorsiflexion in mice leads to significant transverse compressive strain at the tendon insertion point.

Summary: This study investigated the imaging parameters associated with persistent symptoms in postoperative Achilles tendons using B-Mode, Power Doppler, Ultrasound Tissue Characterization, and Shear Wave Elastography. The results showed that symptomatic tendons had increased neovascularization and lower SWE values compared to asymptomatic tendons, indicating potential diagnostic utility for PD-US and SWE in detecting current symptoms.

Summary: This study evaluated the immediate effect of running a marathon on Achilles tendon anteroposterior thickness. The results showed that running a marathon resulted in an immediate decrease in the anteroposterior diameter of the Achilles tendon, without changing the proportion of structural abnormalities or pain.

Summary: The aim of this study was to investigate the correlation between Achilles tendon resting angle (ATRA) and ultrasonography measurements of Achilles tendon length, as well as other clinical outcome measurements. The results showed a negative correlation between ATRA and tendon elongation, and a positive correlation between ATRA and heel-rise height. However, ATRA cannot be recommended as a direct surrogate for determining Achilles tendon length using ultrasonography.

Summary: This study aimed to investigate the association between AT softness and carotid atherosclerosis and ASCVD in FH patients. The results showed that AT softness was associated with age and inversely correlated with overweight. In FH patients, there were significant inverse correlations between AT softness and maximum and mean IMT within the common carotid artery.

Summary: Previous research has shown that total ankle arthroplasty (TAA) can affect the Achilles tendon moment arm, with changes in location of the talar dome potentially influencing these alterations. While there were no significant mean differences in Achilles tendon moment arm between pre- and post-TAA, absolute changes in 3D moment arm were significantly different from zero and partially explained by changes in the location of the talar dome as measured using radiographs.

Summary: This study evaluated the effect of vascular modulation on rat Achilles tendon healing, finding that late delivery of anti-VEGF antibody temporarily reduced healing capacity, but led to improvement later on. VEGF delivery had minimal impact on healing and vascular changes in both early and late delivery times.

Summary: In patients with Achilles tendinopathy, traditional sonographic measures showed increased tendon thickness, hyperemia, and hypoechogenicity in the symptomatic tendon compared to the contralateral side. However, lower shear wave speed (SWS) was observed only in the free tendon, indicating localized alterations in tendon elasticity associated with Achilles tendinopathy.

Summary: The use of BM-MSCs in tissue-engineered tendon constructs promotes tendon tissue regeneration, as demonstrated by parallel collagen fibers, spindle-shaped tenocytes, and neovascularization six months post-surgery. In contrast, the control group without cells showed incomplete regeneration filled with nonspecific fibrotic tissue.

Summary: This study compared in-shoe heel lifts with calf muscle eccentric exercise in reducing pain and improving function in mid-portion Achilles tendinopathy, finding that heel lifts were more effective at 12 weeks. However, the difference in efficacy did not meet the predetermined minimum important difference.

Summary: This review investigated if exercise induced hypoalgesia (EIH) occurs following isometric muscle contraction in individuals with local musculoskeletal symptoms. Findings showed that while EIH was reported in some studies, there was no consistent data to support the superiority of isometric exercises over comparison interventions, and no consistent evidence for EIH following isometric exercise in people with musculoskeletal pain.

Summary: The study aimed to estimate the pooled prevalence of patellar tendon abnormalities observed on imaging in people without symptoms. Significant heterogeneity was found among the studies, partly due to differences in participant activity levels and imaging modalities. More research is needed to establish a clear method for assessing and reporting patellar tendon abnormalities.

Summary: The primary objective of this study was to investigate the presence of a conditioned pain modulation (CPM) effect in people with localised mid-portion Achilles tendinopathy and any changes over a 12-week period. The study found that patients with chronic, unilateral mid-portion Achilles tendinopathy and no other comorbidities are likely to exhibit a meaningful CPM effect.

Summary: This study investigated the relationship between load tolerance of single leg isometric knee extension and athlete-reported knee pain location and severity during the single leg decline squat. The results showed that athletes with diffuse pain had lower load tolerance, while athletes with focal pain tolerated similar loads to those without pain. Furthermore, higher knee pain severity was associated with a consistent reduction in load tolerance.

Summary: There is limited evidence on the cost-effectiveness of diagnostic imaging for back, neck, knee, and shoulder complaints. Decision analytic modelling studies are needed to address methodological and knowledge gaps in this area. It is important to assess the value for money of these commonly used diagnostic imaging services.

Summary: The primary objective of this study was to explore the barriers preventing clinicians from implementing ideal practice in using tools for diagnosis and monitoring of mid-portion Achilles tendinopathy. The secondary objectives were to describe the assessments used by clinicians in their own practice for diagnosis and monitoring, and to explore the outcome measure domains considered most and least important. The study identified financial and time constraints, limited access to equipment, and patient symptom severity as main barriers. The most important outcome measure domains for diagnosis were pain on loading and pain over a specified time frame, while for monitoring progress they were pain on loading, patient rating of the condition, and physical function capacity.
