Group Intervention Description Neural Ice injections Neural Ice This therapy will be injected around the superolateral, superomedial, and inferomedial genicular nerves. Corticosteroid injection Triamcinolone acetate Intraarticular corticosteroid injection is defined as a single dose of Triamcinolone 40mg injected directly into the joint space.
