PRP for the Treatment of Rotator Cuff Tendinopathy Platelet rich plasma (PRP) injections have been studied in their role in treating rotator cuff pathology. Rotator cuff pathology can range from tendinopathy to partial thickness tears. Patients with rotator cuff tendonitis typically complain of pain with overhead arm motion, nocturnal pain, and pain that limits their activities of daily living.
Corticosteroid injections have been shown to release metalloproteinase, which are associated with tendon degeneration. The aim of this review is to see if there is evidence for the use of a PRP injection for the treatment of RTC. The platelets found in PRP will release growth factor that are responsible for cell recruitment, angiogenesis, and possible immunomodulatory effects.
In recent years, we have aimed at personalizing PRP by controlling the amount of leukocytes that are present and increasing the platelet concentration. It is also important to note that none of the studies reviewed pulled the same amount of blood. In a study in Skeletal Radiology, they pulled 10mL of blood, which led to a doubling in platelet concentration.
They found at 12 months there were improvements in visual analogue pain score in the PRP group. They also found that in patients who had nocturnal pain, it had resolved in 86% after PRP injection. The injections were performed under ultrasound guidance and the PRP injections were placed within the partial thickness tear and the tendinopathy injection was placed within the center point of the thickened tendon.
In a study published in Sports Medicine, they compared a subacromial corticosteroid injection verse an intra-lesional PRP injection. They found that partial thickness rotator cuff tears decreased in size in the PRP group. The steroid injection did not lead to an increase or decrease in cuff tear size.
If you are experiencing symptoms that may be related to prp injections for the treatment of rotator cuff tendinopathy, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
