Brief Summary

Platelets are small cells found in the blood that help form clots and stop bleeding. Platelet-rich plasma is blood that contains more platelets than normal and can be given to help people with pain. Tears of the Labrum to the hip (the cartilage "suction cup" that holds the ball to the socket of the hip) cause hip pain. The study wants to see if a portion of the patient's blood, the platelets, will help relieve hip pain and function. Participation requires completing surveys by email, text message, in person, and/or by telephone. Medical tests will also be done to track the health of participants.

Outcome Measures

Primary Outcomes (3)

• Global Assessment Score

  Global patient satisfaction was assessed prospectively at 6 months following the intervention using a numeric rating scale ranging from 0 to 100. Participants were asked to rate their hip, where 0 represented "worst possible" and 100 represented "best possible." The score reflects the participant's overall perception of their injection, including symptom improvement and overall experience.

  6 Months

• International Hip Outcome Tool (iHOT-12)

  Description: The International Hip Outcome Tool-12 (iHOT-12) is a validated, patient-reported outcome measure designed to assess symptoms, functional limitations, and quality of life in young, active individuals with hip disorders. Structure: The iHOT-12 consists of 12 items that capture four domains: Symptoms and Functional Limitations Sports and Recreational Activities Job-Related Concerns Social, Emotional, and Lifestyle Concerns Each item is presented as a visual analog scale (VAS). Scoring: Each item is scored from 0 to 100. 0 = severe symptoms/extreme limitations 100 = no symptoms/no limitations The overall score is calculated as the mean of all answered items (range 0-100), with higher scores indicating better hip function and quality of life.

  6 Months

• EQ VAS (EuroQual Visual Analog Scale)

  The EQ Visual Analog Scale (EQ VAS) was used to assess participants' self-rated overall health at the primary end-point. Participants rated their health on a scale from 0 to 100, where 0 represents the worst imaginable health and 100 represents the best imaginable health. Higher scores indicate better perceived health status.

Limitations and Caveats

This study is limited by small sample size, convenience sampling, lack of control group, and lack of blinding. Outcomes were patient-reported without physical examination, which may have provided additional information on hip pain and function after PRP. There was wide age variability (18-49 years). Although Tonnis grade ≥2 was excluded, distinguishing traumatic labral tears from degenerative changes is difficult. Some patients required additional injections or surgery.
