Spouse has a complete tear of the supraspinatus with two centimeters of retraction. Been to several Dr.’s in the area, getting mixed advice, not interested in getting surgery. She is 69 yrs. old plays lots of tennis, and golf. I guess my question is, if no surgery, can PRP, and poss. Stem cell relieve pain enough to return to former activity level? Lastly, if surgery were to be done, are better results possible if PRP & Stem cell treatments are part of the treatment?
