Receptogenesis in a Vascularized Robotic Embodiment

Advanced Science, EarlyView.
Functional augmentation of situated robots via ex novo hardware generation extends physical adaptability. Drawing inspiration from open circulatory systems for mass and function redistribution, this study presents a vascularized robotic composite exhibiting receptogenesis ‐ the on‐demand construction of sensors ‐ from internal fluid reserves based on ...

Patellar Tendon Revision Reconstruction Using Transosseous Patella All‐Suture Anchors, Semitendinosus Autograft, and Achilles Allograft

Arthroscopy Techniques, EarlyView.
Abstract Patellar tendon rupture is an uncommon but highly treatable injury, with excellent repair outcomes and low reoperation rates. Chronic patellar tendon ruptures or repair failures pose a clinical challenge, but the success rates of reconstruction with extensor mechanism allograft or autograft are reported to be high in the literature. Still, the

Dual‐Camera Arthroscopic Bone Block Cerclage Technique Using a Tricortical Iliac Crest Autograft for Glenoid Reconstruction in Patients With Anterior Shoulder Instability

Arthroscopy Techniques, EarlyView.
Abstract Arthroscopic‐assisted grafting of the anterior glenoid in instability surgery offers lower morbidity and fewer complications than open techniques but faces challenges in operative field visualization. The 1.9 mm NanoScope (Arthrex, Naples, FL) enables simultaneous arthroscopic views from opposing angles, providing anterior glenoid ...
