Frontal Tendon Lengthening Plasty for Treatment of Structural Patella Baja

Arthroscopy Techniques, 2016
Patella baja is a severe complication seen after trauma, prolonged immobilization and surgery. Several surgical methods have been described to proximalize the patella without a change in the patella tendon length.

To Resurface or Not to Resurface the Patella in Total Knee Arthroplasty, That Is the Question: A Meta-Analysis of Randomized Controlled Trials

Medicina, 2022
Background and Objetives: Currently, total knee arthroplasty is one of the most common surgeries, increasing with the increase in life expectancy. Whether or not to replace the patella has been a subject of debate over the years, remaining in controversy

Dynamic Physicochemical Gradients for Tendon–Bone Regeneration

Advanced Functional Materials, EarlyView.
Dynamic physicochemical gradients offer a framework for reconnecting soft tendon and hard bone. This Review examines how hydration, transport, loading and degradation reshape these gradients during healing. Coordinating regional biological cues with progressive transfer of load from scaffold to tissue guides the design of interfaces that retain ...

Patellar Tendon Allograft Reconstruction Using Achilles Graft With Traversing Suprapatellar Cerclage Limbs. [PDF]

Arthrosc Tech
Abstract Patellar tendon rupture and chronic extensor mechanism deficiency present significant reconstructive challenges, particularly in revision settings or when native tissue quality is poor. We describe a reproducible surgical technique for patellar tendon reconstruction using an Achilles allograft with traversing suprapatellar cerclage limbs. This

Programmable Microgel Degradation in Dynamic Granular Hydrogels Guides Extracellular Matrix Assembly During Tissue Repair

Advanced Materials, EarlyView.
This study reports on the chemical modification of hyaluronic acid to create hydrogels with hydrolytic degradability ranging from 2–28 days. Granular hydrogels that undergo timed degradation to increase porosity enhance cell invasion and provisional ECM remodeling in a muscle injury model, leading to reduced fibrosis and improved regeneration ...

Muscle Control of an Extra Robotic Digit

Advanced Robotics Research, EarlyView.
This study compares muscle‐ and movement‐based control for operating a supernumerary robotic thumb. While movement control performs better in the proposed tasks, muscle‐based (EMG) control promotes broader motor learning. The results highlight the promise and challenges of using biosignals for human augmentation, offering new insights into intuitive ...

On the role of the J-E constitutive relationship in applied geoelectromagnetism

Annals of Geophysics, 2003
In current applications of the Induced Polarization (IP) method, the Debye and Cole-Cole models are used to study relaxation and dispersion properties of rocks, though it is believed that this type of modelisation is confused and vague, because
