What the trial is, and whether it could suit you
The experimental group will receive intralesional injections of platelet-rich plasma, evaluating its ability to relieve pain and provide sustained improvement through biological modulation of the joint and tendon environment. In contrast, the control group will be treated with a combination of betamethasone and ropivacaine, representing the current standard of care for short-term inflammatory pain management. The comparison between these two options will determine whether platelet-rich plasma offers advantages in terms of clinical efficacy and duration of benefits. The results obtained could contribute significantly to the development of more effective protocols and more precise management guidelines for patients with chronic omalgia, thus addressing existing controversies and improving clinical practice.
