Prospective, multi-center, randomized trial comparing platelet rich plasma (PRP) versus corticosteroid injection for the treatment of symptoms of knee osteoarthritis. The purpose of the study is to determine which therapy provides a greater reduction in patient reported outcome measures of pain and function.
Platelet rich plasma has become increasingly utilized as a treatment option for knee osteoarthritis. Corticosteroids is currently an approved medication to treat the symptoms of the knee osteoarthritis. There is limited evidence in a prospective randomized manner powered adequately to determine a difference between these treatments for pain associated with knee osteoarthritis.
Prospective, multi-center, single blind (participant), randomized trial comparing platelet rich plasma (PRP) versus corticosteroid injection for the treatment of symptoms of knee osteoarthritis. The purpose of the study is to determine which therapy provides a greater reduction in patient reported outcome measures of pain and function.

| Pain score VAS | Visual Analogue Scale (VAS) measures pain intensity. The VAS consists of a 10 cm line, with two end points representing 0 ('no pain') and 10 ('pain as bad as it could possibly be'). Pain intensity that is calculated by measuring the distance from the "no pain" end of a line to a mark placed by the patient to indicate their current pain level. This will be measured at baseline, six weeks, and three months. | Baseline, six weeks, and three months. |
| Measure | Description | Time Frame |
|---|---|---|
| Pain Score NRS | Numeric Pain Rating Scale (NRPS) where patients are asked to rate their pain on a scale of 0 to 10, with 0 representing "no pain" and 10 representing "the worst pain imaginable. This will be measured at baseline, six weeks, and three months. | Baseline, six weeks, and three months. |

Given the nature of this study, blinding will not be possible for the treating surgeon and research staff. The participants will be blinded from the regimen that they receive, and both groups will have blood drawn and the injection will be covered in a manner to ensure participants cannot ascertain the treatment regimen.

Knee Injury and Osteoarthritis Outcome Score (KOOS) is a self-reported outcome measure assessing the patient's opinion about the health, symptoms, and functionality of their knee. It is a 42-item questionnaire, including 5 subscales: symptoms, pain, ADLs, sports/recreation, and quality of life. KOOS is used for any knee pathology and was found to be useful in assessing patients of various age populations, ranging from young to elderly adults. Scores range from 0 to 100 with a score of 0 indicating the worst possible knee symptoms and 100 indicating no knee symptoms. This will be measured at baseline, six weeks, and three months. |
| Baseline, six weeks, and three months. |
| Functional score WOMAC | The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used in the evaluation of Hip and Knee Osteoarthritis. It is a self-administered questionnaire consisting of 24 items divided into 3 subscales: Pain (5 items): during walking, using stairs, in bed, sitting or lying, and standing upright. The total WOMAC score is the sum of the three subscale scores, with a possible score range of 0-96. Higher scores indicate worse pain, stiffness, and functional limitations. This will be measured at baseline, six weeks, and three months. | Baseline, six weeks, and three months. |
| Pain Medication Adherence | Measured by number of days until pain medication (acetaminophen) is not adequate. | Baseline through three months. |
