Brief summary
Hypothesis: Ketorolac injection is a cost-effective adjunct in the nonoperative treatment of knee osteoarthritis (OA) compared to steroids and viscosupplementation. Aims/objectives: The objective of this randomized, controlled, double-blinded, prospective study is to assess the efficacy and cost-effectiveness of knee injection with ketorolac in the nonsurgical management of symptomatic OA compared to injections with corticosteroids and viscosupplements.
Detailed description
The purpose of this research study is to examine the effectiveness of intra-articular (inside the joint) ketorolac injection compared to injection with either corticosteroid or hyaluronic acid for the treatment of painful knee osteoarthritis. Patients will be randomly assigned to receive either ketorolac (a nonsteroidal anti-inflammatory drug, methylprednisolone (a steroid), hyaluronic acid (a substance that is naturally present in the human body).
Interventions
One knee injection of 2cc of ketorolac tromethamine (15mg/cc) in 5cc of 0.5% ropivacaine hydrochloride without epinephrine
One knee injection of 2 cc of methylprednisolone acetate (40mg/cc) in 5cc of 0.5% ropivacaine hydrochloride without epinephrine
One knee injection of Hylan G-F 20 (Synvisc-One)
