Comparing Mesenchymal Stem Cell Counts in Unilateral vs. Bilateral Posterior Superior Iliac Spine Bone Marrow Aspiration
Comparing Mesenchymal Stem Cell Counts in Unilateral vs. Bilateral Posterior Superior Iliac Spine Bone Marrow Aspiration
Musculoskeletal conditions are common sources of pain. Specifically, osteoarthritis affects
 nearly 27 million people in the United States. This disease leads to the breakdown of the
 cartilage surfaces of the joints, which serve as the connection points between the bones of
 the body, causing a large amount of pain and disability in patients. Increasing the number of
 available treatment options for osteoarthritis is becoming increasingly more important as
 Americans continue to age. Using stem cells taken from bone marrow is one of the
 non-operative treatments that has been gaining popularity in the recent past. This study aims
 to clarify how this procedure should best be done by comparing stem cell concentrations and
 patient outcomes (short and long term) in patients who have stem cells taken from one area vs
 two (unilateral vs bilateral posterior superior iliac spine (PSIS) aspirations).

 This research study involves the participant being randomly placed into one of two groups;
 one group will have cells taken from one hip, and the other will have cells taken from both
 hips. Both of these approaches are performed in clinics currently, and both are considered to
 be standard of care. All bone marrow collected for the purposes of this study will be
 obtained by the principal investigator while performing the standard procedure. In obtaining
 these sample the physicians will abide by the standard of care set forth for the Bone Marrow
 Aspiration Concentrate procedure.
