Advances in Interventional Radiology Technology for the Treatment of Knee Osteoarthritis

Minimally invasive interventional radiology procedures play an adjunctive role in treating the symptoms of osteoarthritis (OA) with the hopes of delaying total knee arthroplasty (TKA). However, currently available intra-articular injections offer only short-term benefits. This has led to evolution of new techniques such as genicular artery embolization and genicular nerve ablation, which show benefit in pain control and quality of life, especially for mild-to-moderate OA, positioning these techniques as potential alternatives to intra-articular injections to help delay TKA.
