Can a shot of your own blood cells boost hip surgery results?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria and Rationale: 1. Age 18 or older: patients of any age have the capacity to potentially benefit from labral repair 2. Symptoms consistent with a tear of the acetabular labrum (i.e., catching, clicking, popping, pain with sitting, episodic pain, pain with hip flexion, adduction, and/or internal rotation): asymptomatic labral tears do exist in the general population however there is not definitive evidence to suggest treatment of asymptomatic tears is beneficial. 3. Symptoms not due to some other acute process in or around the hip (including septic arthritis, osteonecrosis, hemarthrosis, iliotibial band syndrome, fractures of the femoral neck or head, fractures of the acetabulum, greater trochanteric pain syndrome, sacroiliac joint pain, piriformis syndrome, low back pain associated with hip pain and not knee nor acute low back injury): certain conditions are not treatable by either arthroscopy or physical therapy. Some of these conditions can be managed with physical therapy but not arthroscopy. 4. Availability of hip radiographs and magnetic resonance imaging (MRI and/or MRA): needed to assess eligibility 5. Evidence of labral tear on MRI and/or MRA: documentation of acetabular labrum tear 6. Willingness to participate and ability to understand and sign informed consent document: ability to understand study and consent willingly 7. Returning subjects enrolled in protocol 2017P001391/PHS Exclusion Criteria and Rationale: 1. Non-English speaking subjects: PROMs are only validated in English. 2. Systemic infection: surgery is generally contraindicated when systemic infection is present. 3. Systemic heparinization: the vascularity of the bone and adjacent tissues is significant, posing a potential problem for bleeding when the patient is anti-coagulated. 4. Pregnant women/fetuses: although surgery can be performed on pregnant women, pregnant women are excluded under federal regulations.
