Percutaneous Skeletal Fixation of Painful Subchondral Bone Marrow Edema Utilizing an Injectable, Synthetic, Biocompatible Hyaluronic Acid–Based Bone Graft Substitute

Abstract

Subchondral bone marrow edema (SBME) represents a pathologic alteration of subchondral bone. A strong correlation exists between its presence and the progression of osteoarthritis. Very few treatment options exist between the spectrum of conservative management and the definitive treatment of total knee arthroplasty (TKA). Tactoset® is an injectable synthetic, biocompatible hyaluronic acid–based bone graft substitute that allows for a minimally invasive treatment for painful SBME via percutaneous skeletal fixation (PSF). We present the technique of PSF using Tactoset.
