Study Overview
Brief Summary
This study will explore the effectiveness of intra-articular knee injections in patients with osteoarthritis by comparing Corticosteroid (triamcinolone) vs Platelet Rich Plasma (PRP).
This study is a randomized controlled trial with a sample size of one hundred and sixty patients (160). Patients would be recruited via new referrals and follow-up appointments in the Orthopaedic clinic at the UHWI (University Hospital of the West Indies) with knee osteoarthritis.
The aim of the study is to:
- To determine if platelet-rich plasma injections are better at improving functional outcomes in the knee using Western Ontario and McMaster Universities Arthritis Index (WOMAC) when compared to intraarticular steroids.
- To identify adverse reactions related to these injections
Detailed Description
This study will explore the effectiveness of intra-articular knee injections in patients with osteoarthritis by comparing Corticosteroid (triamcinolone) vs Platelet Rich Plasma (PRP).
This study is a randomized controlled trial with a sample size of one hundred and sixty patients (160). Patients would be recruited via new referrals and follow-up appointments in the Orthopaedic clinic at the UHWI (University Hospital of the West Indies) with knee osteoarthritis.
The recruitment period will run from July 31, 2023 to January 31, 2024 and a subsequent year of follow-up for each patient.
Selected patients will be informed of the study and given informed consent to fill out once they meet the inclusion criteria. Information will be stored on a password-encrypted external storage device that can only be accessed by the investigator or supervisor. Data will be analyzed using Statistical Package for the Social Sciences (SPSS).
The study will be conducted according to the good clinical practice guidelines of the World Medical Association (WMA) declaration of Helsinki which addresses research on human subjects and will conform to local laws and ethical requirements of the Ministry of Health.

Outcomes
Primary Outcomes
Pain of the Knee
Time Frame: 1 year of follow up visits, post injection. Follow up will be done at 2 weeks, 3 months, 6 months, and 1 year.
For pain we are primarily using the visual Analogue scale, which is a subjective pain rating numerical scale where the patients rate their pain on a scale of 0-10. The Visual Analogue Scale is a scale from 0-10, where 0 = No Pain and 10 = Worst Pain Possible. The scale also uses faces to indicate the level of pain.
Function of the knee
Time Frame: 1 year of follow up visits, post injection. Follow up will be done at 2 weeks, 3 months, 6 months, and 1 year.
For Function we are primarily using the Western Ontario and McMaster Universities Arthritis index (WOMAC), which is a commonly used tool to assess pain and function in patients with arthritis. This is a self administered questionnaire with 24 items in 3 subscales (1) 5 points evaluate pain (2) 2 points stiffness (3) 17 points function a numerical score is calculated and used for comparison. The WOMAC index uses a scale of 0-4 to rate pain, stiffness and difficulty when doing certain activities, where 0 = None and 4 = Extreme.
Secondary Outcomes
No secondary outcomes reported
