3D‐Printed Piezoionic/Bioelectronic Hydrogel for Electro‐Metabolic Regulation of Osteogenic Differentiation

Advanced Healthcare Materials, EarlyView.
A 3D‐printed piezoionic GPMx hydrogel enables stable electromechanical signal generation under mechanical loading, exhibiting long‐term durability and low fatigue. As a bioactive patch, it restores endogenous bioelectricity to stimulate osteogenesis via Ca2+ influx and mitochondrial activation, while simultaneously enabling label‐free alkaline ...

Addressing sagittal plane imbalance in primary total knee arthroplasty: functional alignment outperforms kinematic and mechanical alignment techniques

Bone & Joint Open
Aims: Sagittal plane imbalance (SPI), or asymmetry between extension and flexion gaps, is an important issue in total knee arthroplasty (TKA). The purpose of this study was to compare SPI between kinematic alignment (KA), mechanical alignment (MA), and ...

Total versus partial knee replacement in patients with medial compartment knee osteoarthritis: the TOPKAT RCT

Health Technology Assessment, 2020
Background: Late-stage medial compartment knee osteoarthritis can be treated using total knee replacement or partial (unicompartmental) knee replacement. There is high variation in treatment choice and insufficient evidence to guide selection. Objective:

The geometric knee replacement in polyarthritis [PDF]

The Journal of Bone and Joint Surgery. British volume, 1982
The British Orthopaedic Association assessment questionnaire for knee replacements was adapted to allow comparison of the severity of underlying polyarthritis with the benefits of geometric knee replacement in a retrospective study of 150 knees between six months and six years after operation.

Use of Topical (Intra-articular) Tranexamic Acid to Minimise Blood Loss and Transfusion in Total Knee Replacement Surgery [PDF]

, 2010
Introduction Total knee replacement (TKR) is a common orthopaedic procedure, with 20-70% of patients needing 1-3 units of blood, although allogeneic transfusion is not risk free.

The Complexity of Human Walking: A Knee Osteoarthritis Study [PDF]

, 2014
This study proposes a framework for deconstructing complex walking patterns to create a simple principal component space before checking whether the projection to this space is suitable for identifying changes from the normality.
