Background: Injuries of the patellar tendon commonly occur as a result of mechanical loading of the tendon during physical activity. Shear wave elastography (SWE) is an established technique for assessing tendon stiffness, and has good interindividual reliability. The aim of this study was to investigate the impacts of physical parameters and different sports on patellar tendon stiffness in professional athletes using SWE.
Methods: Standardized patellar tendon SWE was performed in a relaxed supine position with a small roll under the knee (20° flexion) in 60 healthy professional athletes (30 female, 30 male). Multiple linear regression was performed for patellar tendon stiffness including gender, age, body mass index (BMI), and type of sport.
Results: Patellar tendon stiffness showed no significant difference between female (3.320 m/s) and male (3.416 m/s) professional athletes. Mean age (female: 20.53 years; male: 19.80 years) and BMI (female: 23.24 kg/m; male: 23.52 kg/m) were comparable. Female professional athletes with oral contraceptive (OC) intake showed higher patellar tendon stiffness than athletes without OC intake (3.723 versus 3.017; = 0.053), but not significantly.
Conclusion: In professional athletes, there are no significant differences in patellar tendon stiffness according to gender, age, BMI and type of sport (handball, volleyball, soccer, sprint, hammer throw). Oral contraceptives may not have an impact on patellar tendon stiffness in female athletes. Further studies are necessary.

Introduction: The extent of change in Patient Reported Outcome Measures (PROs) required to meet surgeon-defined satisfactory outcomes after isolated Medial Patellofemoral Ligament Reconstruction (MPFL-R) has not been reported. The primary aim of the study was to define the threshold value of maximal outcome improvement (MOI) in PROs associated with surgeon-defined satisfactory postoperative outcomes. The secondary aim was to identify the most effective PRO in predicting these outcomes and to evaluate the factors associated with it.

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.

Objective: To compare tibial tubercle-trochlear groove (TT-TG) and tibial tubercle-Roman arch (TT-RA) distances in patients with patellar dislocation or subluxation, evaluate TT-RA reliability and reproducibility, and determine pathological threshold values for surgical treatment using magnetic resonance imaging (MRI) and computed tomography (CT).
Materials And Methods: Retrospective analysis included 259 patient and 262 control examinations of knee MRIs and/or CTs performed. TT-RA, TT-TG, and tibial tubercle-posterior cruciate ligament (TT-PCL) distances, Roman Arch height, trochlear sulcus angle, and total femoral condyle width were measured by two radiologists, and trochlear morphology was assessed.

Purpose: Slope-reducing high tibial osteotomies (SR-HTOs) correct posterior tibial slope (PTS) abnormalities in patients with anterior knee instability, as in cases of anterior cruciate ligament (ACL) deficiency. The SR-HTO techniques, including infra-tubercle and retro-tubercle approaches, provide distinct benefits: retro-tubercle techniques help preserve patellofemoral joint mechanics, while infra-tubercle techniques are effective in mitigating iatrogenic varus. However, there is limited comparative literature available.

Purpose: There is a paucity of studies reporting patient acceptable symptom state (PASS) thresholds for patient reported outcome measures validated for patellar instability. The aim of this study was to determine the PASS threshold for the Banff Patellofemoral Instability Instrument 2.0 (BPII) following surgery for recurrent patellar instability.
