This study is looking at how well different injections work for primary glenohumeral osteoarthritis (GHOA), which is arthritis in your shoulder joint. Researchers want to compare corticosteroid injections with platelet-rich plasma (PRP) injections to see which is better at reducing pain. These injections are commonly used to help with pain and potentially delay or prevent the need for shoulder surgery. You may be able to join if you are at least 18 years old, have been diagnosed with primary GHOA, and have a baseline pain level above 4 on a pain scale. The main goal is to measure your pain level 12 weeks after the injection. The current recruitment status is unclear, but the study plans to enroll 200 people.
