Detailed Description
As non-surgical treatments of OA are essential, multiple trials have been done to compare standard of care IA injection therapies to more novel injection treatments, with many of these trials using saline as the control arm. The purpose of using a control arm is to attempt to eliminate placebo effect and help distinguish the true effectiveness of a therapy. There has been controversy over the clinical effect of saline in treating OA with some arguing that saline may have some clinical benefit. If this is true, it could allow for the true effect of standard of care therapies to appear diminished when compared to saline as a placebo. A recent meta analysis looked at the use of saline as a placebo in 38 randomized control trials to determine if intra-articular saline injections for knee OA had a clinical effect. The study found that IA injections of saline significantly improved short-term knee pain in 32 of the studies which involved 1705 patients, p <0.001, and long-term pain was significantly decreased in 19 of the studies involving 1445 patients, p <0.001. It is essential to empirically determine if saline has a clinical effect due to the role it plays as a placebo in many clinical studies of the management of OA with intra-articular injections.
Objective: To investigate the clinical benefit of intra-articular injections of saline in patients with symptomatic osteoarthritis of the knee and compare the clinical response of saline to the current standard treatment with corticosteroids and an air injection placebo.
Study Design: Prospective, single-blinded, randomized, clinical study. Patients will be randomized into three treatment arms in a 1:1:1 fashion with approximately 50 patients in the saline arm, 50 patients in the corticosteroid arm, and 50 patients in the placebo arm.
Null Hypothesis: Clinical knee outcomes of subjects following one intra-articular knee injection of air will be similar to one intra-articular knee injection of saline or corticosteroid for symptomatic patients diagnosed with knee OA.
Statistical Assumptions: Power Analysis
Investigational Arm: 10 ml Saline (Normal Saline)
Control Arm: 1 ml of 40 mg corticosteroid in 9 ml 1% lidocaine (Depo-medrol, Pfizer, New York, New York), 10 ml air (placebo)
Primary Efficacy Endpoint: The primary efficacy endpoint is the mean change in the WOMAC Index score 12 weeks after first injection with regards to baseline score.
Secondary Efficacy Secondary efficacy endpoints include the change in the full Endpoints: WOMAC Index, KOOS, Lysholm, IKDC, VAS, SF-12 and use of rescue medication (steroid at 12 weeks).
Enrollment: Prospective, randomized, clinical study designed to evaluate 150 subjects. All enrolled subjects will have a pre-procedure visit, one treatment visit, and follow-up visits at week 6 and week 12 if they require a rescue injection and will fill out patient reported outcome measures at 1, 6, 12, and 24 weeks.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Knee injection with corticosteroids
Using clinically accepted methods, subjects will undergo a palpation guided injection of corticosteroids into the knee joint.
Subjects will then return for follow-up visit at 12 weeks for a physical exam of the knee.
Patients will fill out questionnaires online at 1, 6, 12 and 24 weeks.
|
Patients will receive an ultrasound guided intra-articular injection of 40 mg Depo-Medrol in 1 ml, 9 ml of 1% lidocaine

Placebo Comparator: Knee injection with saline
Using clinically accepted methods, subjects will undergo a palpation guided injection of saline into the knee joint.
Subjects will then return for follow-up visit at 12 weeks for a physical exam of the knee.
Patients will fill out questionnaires online at 1, 6, 12 and 24 weeks.

Patients will receive an ultrasound guided intra-articular injection of Normal Saline 10 ml

Sham Comparator: Knee injection with air
Using clinically accepted methods, subjects will undergo a palpation guided injection of air into the knee joint.
Subjects will then return for follow-up visit at 12 weeks for a physical exam of the knee.
