Article Abstract
Objective: Although the incidence of contralateral Achilles tendon in patients with Achilles tendon rupture is higher than in the general population, there are no studies evaluating the status of the contralateral Achilles tendon. The aim of this study was to investigate the status of the contralateral Achilles tendon in patients with acute Achilles tendon rupture.
Design: Prospective observational cohort study.
Setting: University hospital foot and ankle clinic.
Participants: Seventy-five patients with acute Achilles tendon rupture who met the inclusion criteria.
Intervention: Ultrasonography performed by an orthopedic surgeon who had 8 years of experience in musculoskeletal ultrasonography.
Main Outcome Measures: Ultrasonographic abnormalities of the contralateral Achilles tendon at the time of diagnosis of acute Achilles tendon rupture. Abnormalities were categorized as intratendinous lesions, peritendinous lesions, changes in retrocalcaneal bursa, and Achilles tendon thickening.
Results: The maximal Achilles tendon thickness had a mean of 4.8 ± 1.0 mm. Nine patients (12%) showed ultrasonographic abnormalities on the contralateral Achilles tendon, and the presence of exertional pain was the sole associating variable with ultrasonographic abnormalities.
Conclusion: The prevalence of ultrasonographic abnormalities in the contralateral Achilles tendon shown in this study was not higher than that reported in healthy or asymptomatic Achilles tendon. Therefore, routine evaluation of the contralateral Achilles tendon is unnecessary at the time of acute Achilles tendon rupture.

Increasing ground contact time reduces Achilles tendon forces during rearfoot strike running outdoors.

Objectives: Strategies to reduce Achilles tendon forces during running may be beneficial for injury prevention. Increasing ground contact time could reduce Achilles tendon forces during running but may also elicit changes in cadence that could offset these reductions. The purpose of this study was to determine if changing ground contact time altered Achilles tendon forces during running, with both a fixed and a free cadence.

Objectives: To explore the prevalence and distribution of ultrasound-detected lesions indicating structural damage at the enthesis (e.g., bone erosions, enthesophytes, and calcifications) in patients with spondyloarthritis (SpA), comparing those with axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA), and to investigate the demographic, clinical, and metabolic factors linked to these lesions.

Background: Chronic Achilles tendinopathy is characterized by persistent pain, swelling, and functional limitations, particularly in overweight middle-aged women. This demographic is predisposed to tendon degeneration due to biomechanical overload and hormonal fluctuations.
Objective: This study aimed to compare the effectiveness of an aquatic neuromuscular exercise program vs.

OrthoCarolina, Charlotte, North Carolina, USA.
Background: Midsubtance Achilles tendon ruptures remain the most common tendon injury within the lower extremity. While the incidence continues to rise, changing immobilization protocols, surgical techniques, and surgeon preferences have evolved over the past few decades.
Purpose: To compare the overall complication rate among 3 major surgical techniques (open, percutaneous, and suture anchor) across a large, heterogeneous orthopaedic group in a major metropolitan area.
Split Anconeus Fascia Transfer for Posterolateral Rotatory Instability of the Elbow.

Posterolateral rotatory instability (PLRI) of the elbow occurs from chronic lateral ulnar collateral ligament (LUCL) injury leading to subluxation of the ulnohumeral joint and radial head. Patients with failed or untreated LUCL injury can go on to have chronic elbow instability and difficulty with activities that require an axial load on the elbow. Free grafts such as semitendinosus, Achilles, or palmaris longus require fixation on both the humerus and ulna, or may not represent the native LUCL kinematics as a native tendon such as anconeus.
