Study Overview
Brief Summary
This study will compare the accuracy and patient reported outcomes between four different techniques used to perform a knee injection.
Detailed Description
This study will compare the accuracy and patient-oriented outcomes between various techniques for intra-articular knee injections. Historically, a joint line (intercondylar) technique of injection at the medial or lateral joint line, reliant solely upon clinical palpation, has been the most popular approach among primary care and orthopedic providers. Newer approaches, making use of ultrasound visualization to accomplish access to the intercondylar recess and the anterolateral suprapatellar pouch, have gained in popularity. Because of uncertain accuracy with the traditional approach, this study is designed to determine if sonographic visualization combined with either of these two newer techniques improves accuracy and affects patient-oriented outcomes.

- Treatment
- Masking
- Double (Participant, Outcomes Assessor)
Masking Description
Patients will be blindfolded for the duration of their procedure. Investigator will always place ultrasound probe on patient's knee regardless of group assignment to eliminate bias. To further enhance blinding, the ultrasound screen will placed on freeze for the patients randomized into the groups without ultrasound guidance. Radiologist will be blinded to patient's group assignment.

Outcomes
Primary Outcomes
Number of Participants With Successful Knee Injection
Time Frame: Procedure visit 3 (3-4 weeks after 1st injection)
To assess presence or absence of contrast medium within the target knee joint as determined by a blinded radiologist. If contrast medium could be observed in the joint then the injection was considered a success.
Secondary Outcomes
- Procedural Satisfaction Score at 3 Months Post Injection(3 month follow-up appointment following 3rd injection)
- Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Score(Pre-Injection and 3 month follow-up appointment following 3rd injection)
