The primary purpose of this study is to find out if there is a difference in pain experienced in patients with knee arthritis of the inside of their knee if they get a steroid injection on the inside or outside of their knee. Participants will:
1. Be randomly divided into getting their steroid injection on the inside or outside of their knee. 2. Answer a pain survey before their injection as well as over the phone 2 weeks, 6 weeks, and 12 weeks after their injection.
Age ≥ 40
Clinical diagnosis of knee OA with predominant medial compartment symptoms
Radiographic moderate-to-severe medial compartment OA (KL grade 3-4 or equivalent)
Agreed to and preparing to receive a CSI of the knee as part of standard care from surgeon, regardless of past injection of the knee
Predominant lateral compartment OA or patellofemoral-only OA
Inflammatory arthritis (RA, gout flare, etc.)
Suspected or confirmed joint infection or overlying cellulitis
Prior knee arthroplasty on the index knee
Parallel
Anteromedial Injection
Procedure/SurgeryIf randomized to this intervention, patients will receive a corticosteroid injection in the anteromedial side of their knee.
Anterolateral Injection
Procedure/SurgeryIf randomized to this intervention, patients will receive a corticosteroid injection on the anterolateral side of their knee.
