Will prp plus stem cell therapy to injured/ strained si ligaments work? will it cause scar tissue or normal tissue? is it better than prolotherapy?

Experimental: At this point, prp is experimental as only case series are published. No real head to trials against other proven therapies. That said, many athletes and their trainers think it works really well.

Many Possibilities: Prolotherapy typically by itself will cause ligaments to tighten up, usually due to scarring or fibrosis of the ligaments. However now prolotherapy is used to introduce new blood supply to the area and then many times following it with the prp and/or stem cells in the area can repair the tissue/ligaments by the hopes that the stem cells regenerate the same normal tissue type.

Platelet Rich Plasma: There is not much good data that I am aware of showing that prolotherapy is effective. PRP or platelet rich plasma is showing effectiveness in small studies for several indications. These include: Facial rejuvenation, hair regrowth, sexual rejuvenation, arthritis and musculoskeletal injuries, and more. Based on my experience, I recommend PRP therapy.
