Background: While there is evidence that tendon adapts to training load, structural alterations in the patellar tendon in response to training loads are still unclear. The aim of this study is to identify changes in patellar tendon structure throughout pre-season and after finalizing the first competitive cycle.
Methods: Nineteen professional handball players participated in the aforesaid cross-sectional study, in which patellar tendon scan and counter movement jump (CMJ) performance were conducted. Measurements were taken on the first and last day of pre-season training, and at the end of the first competitive cycle.
Results: The results revealed that variation on the tendon structure occurred, mainly at the end of pre-season training; for injured tendons this occurred at the proximal (Right = 0.02), distal (Right = 0.01), and (Left = 0.02) tendon, while changes in healthy tendons occurred at the mid (Left = 0.01) and distal tendon (Right = 0.01). At the end of the first competitive cycle, changes were observed in the distal injured tendon ( = 0.02).
Conclusion: Patellar tendon shows greater structural change after completing pre-season training than at the end of the first competitive cycle, from which it may be inferred that gradual loading during pre-season training allows the tendon to adapt and potentially decrease the onset of patellar tendinopathy.

The anterior cruciate ligament (ACL) of the knee is commonly injured and can lead to joint instability. ACL reconstruction (ACLR) is often required as endogenous healing is limited and the stability provided by dynamic stabilisers is insufficient for complete joint function. A graft, comprising either biological tissue or synthetic material, is used to replicate the biomechanical and structural properties of the native ACL to restore function.

Purpose: Bone-patellar tendon-bone (BPTB) and Hamstring (HT) autografts are commonly used for anterior cruciate ligament reconstruction (ACLR). Concerns exist regarding postoperative anterior knee pain (AKP) and kneeling discomfort with BPTB grafts. However, many studies solely report the presence/absence of anterior knee pain, without assessing its clinical significance in terms of functional limitation or impact on quality of life.

Background And Aims: Polyneuropathy is highly prevalent among kidney transplant recipients (KTR), underscoring the need for an accurate yet easy-to-perform diagnostic method to improve understanding and enable early identification of treatable cases.
Methods: This study included KTR at least 12 months post-transplant at the University Medical Centre Groningen, the Netherlands. An expert panel assessed polyneuropathy through a structured neurological examination, quantitative sensory testing, and nerve conduction studies.

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.
