Clinical Research and Medical Writing, Meril Life Sciences Private Limited, Vapi, IND.
Aim The primary objective of the study was to evaluate the mid-term implant survivability, rate of revisions, and clinical and functional outcomes following patella resurfacing during total knee arthroplasty (TKA) utilizing posterior stabilized (PS) total knee system (TKS). Methods A prospective, single-arm, multi-center, post-marketing surveillance encompassed patients with end-stage primary knee osteoarthritis (OA) or inflammatory arthritis. The time points of the study included baseline, six weeks, six months, one year, and three years post-operatively.

Background: Routine patellar resurfacing remains controversial in primary total knee arthroplasty (TKA). This study reports the experience of a high-volume arthroplasty surgeon who stopped routinely resurfacing patellae for a 3-year period.
Methods: All primary TKAs performed by a single surgeon between January 2018 and September 2022 with minimum 1-year follow-up were retrospectively reviewed.
A Nanocluster Colloidal Electrolyte Enables Highly Stable and Reversible Zinc Anodes.

Aqueous zinc-ion batteries represent a favorable technology for stationary energy storage systems owing to their safety, reliability, and cost-effectiveness. However, Zn anodes suffer uncontrollable dendrite formation and harmful side reactions that lead to a short lifespan. Herein, we demonstrate a nanocluster colloidal electrolyte strategy for stabilizing the zinc anodes.

The benefit of patellar resurfacing in total knee arthroplasty (TKA) remains uncertain, with conflicting evidence regarding associated revision rates and clinical outcomes. Although initial studies have reported higher revision rates associated with unresurfaced patellae, recent evidence questions the necessity of routine patellar resurfacing. This study aimed to evaluate the risk of revision following TKA performed with and without patellar resurfacing using data from the American Joint Replacement Registry (AJRR).

Materials And Methods: Data were retrospectively analyzed for patients who received hip resurfacing between 2010 and 2021. Eligible patients had postoperative radiographs and completed a minimum 2-year follow-up questionnaire for the following patient-reported outcomes: modified Harris Hip Score (mHHS), Harris Hip Score (HHS), Forgotten Joint Score (FJS), visual analog scale (VAS) score, satisfaction, and Hip Disability and Osteoarthritis Outcome Score, Joint Replacement (HOOS-JR).
