The injection process does not take more than an hour, which includes the creation of the PRP as explained above. The platelet-rich portion is collected and injected back into the injured tendon, ligament, muscle, joint, or disc that has been determined to be a source of pain and is not-healing appropriately. When structures around the spine are being injected, x-ray (i.e. fluoroscopy) guidance is used to assure safe and proper placement of PRP at the affected site. In the extremities, ultrasound-guidance is commonly used to inject PRP into the appropriate tendon, ligament or joint that is being targeted. Injections are performed under image guidance to assure precise placement of PRP. The number of injections varies based on each patient’s individualized condition but typically range anywhere from two to six injections done over time. Patients typically experience significant reduction in pain after the first or second injection.
