Background: Functional deficits after Achilles tendon (AT) ruptures are observed. The relationship between musculotendinous structural alterations and functional outcome is not clear.
Methods: Kinematic analyses (level walking, stair climbing), patient-reported outcome measures (PROMs), calf atrophy (maximum calf circumference (MCC)), and AT length were evaluated in patients after percutaneous AT repair with the Dresden instrument (n=20min.
Follow-up: 24 months).
Results: Patients achieved good results in PROMs. However, MCC decreased significantly and AT length increased significantly postoperatively. Side-to-side MCC differences over 2cm resulted in significantly lower PROMs. AT lengthening correlated with increased dorsiflexion and decreased plantarflexion.
Conclusion: Calf atrophy and AT lengthening after minimally invasive AT repair resulted in inferior ankle kinematics and PROMs.

Restenosis remains a long-standing limitation to effectively maintain functional blood flow after percutaneous transluminal angioplasty (PTA). While the use of drug-coated balloons (DCBs) containing antiproliferative drugs has improved patient outcomes, limited tissue transfer and poor therapeutic targeting capabilities contribute to off-target cytotoxicity, precluding adequate endothelial repair. In this work, a DCB system was designed and tested to achieve defined arterial delivery of an antirestenosis therapeutic candidate, cadherin-2 (N-cadherin) mimetic peptides (NCad), shown to selectively inhibit smooth muscle cell migration and limit intimal thickening in early animal PTA models.

Introduction: This report describes the use of a combination of a retrograde femoral nail and distal femur locking plate for the treatment of an open intra-articular distal femur fracture in a 99-year-old female. The purpose of this report is to highlight that nail-plate fixation constructs can be performed percutaneously and expeditiously even in extremely old patients; therefore, patient age should not be a limiting factor in choosing this construct to allow for immediate weight-bearing.
Case Report: The patient was a 99-year-old female who presented to the emergency room after a fall.

In congenital heart diseases (CHD) of moderate to great complexity involving the right ventricle (RV), the morphologic RV can be exposed to significant stressors across the lifespan either in a biventricular circulation in a sub-pulmonary or sub-aortic position, or as part of a univentricular circulation. These include pressure and/or volume overload, hypoxia, ischemia, and periprocedural surgical stress leading to remodeling, maladaptation, dilation hypertrophy and dysfunction. This review examines the macroscopic remodeling of the RV in various forms of CHD and explores remodeling trajectories, along with the effects of surgeries and residual lesion repair, in tetralogy of Fallot, Ebstein anomaly, congenitally corrected transposition of the great arteries, transposition of the great arteries with atrial switch surgery, and single ventricle palliated by Fontan.

Trauma healing is the process of healing after the body has been subjected to an external force and the skin and other tissues have become dissected or defective, showing the synergistic effect of various processes. Therefore, the investigation of innovative wound dressings has significant research and clinical implications. In this study, we constructed a zinc based metal-organic framework (MOF) and loaded with antimicrobial peptide LL37 to prepare LL37@ZPF-2 (ZPF = zeolite pyrimidine backbone), which was subsequently integrated with Poloxamer 407 to fabricate LL37@ZPF-2 thermosensitive hydrogel.

Severe mitral regurgitation (MR) following surgical repair of the mitral valve poses a significant clinical challenge. Patients who have undergone surgery are typically at high risk for a second operation. This report details the case of a 54-year-old male who underwent aortic valve replacement and mitral valve repair using a 34-ring, 14 years prior.
