Development of a small animal bone-anchored limb replacement model for infection interventions.

Purpose: Osseointegration-associated infections are a critical barrier to widespread implementation of osseointegrated (OI) prosthetics. To address this challenge, a preclinical animal model must exist of the human model to test potential interventions. In this article, we describe a novel rabbit model of OI implant-related infection that can act as a platform for rapid translation and development of therapeutic approaches to combat these uniquely challenging infections.

Immunophenotyping of Synovial Tissue in Adolescents Undergoing ACL Reconstruction: What Is the Role of Synovial Inflammation in Arthrofibrosis?

Background: Loss of motion and arthrofibrosis after anterior cruciate ligament (ACL) reconstruction (ACLR) can be devastating complications for athletes. The cellular and molecular pathogenesis of arthrofibrosis is poorly understood, limiting prevention and treatment options. Synovial inflammation may contribute to post-ACLR arthrofibrosis.
