The goal of the study is to enroll 50 subjects in the bone marrow arm (BMAC group) and 50 in the triamcinolone arm (triamcinolone group). Once part fulfill the inclusion criteria, participants will be randomized to either intervention. Participants will be enrolled in a staggering manner for the BMAC arm. The first 4 participants will be enrolled with at least 1 week interval in between these patients. During these weeks, the investigators will obtain results from the BMAC culture and evaluate safety response to the procedure. Participants enrolled in the triamcinolone arm will not be enrolled in a staggering manner, as the safety and efficacy are established as this is part of standard of care for hip osteoarthritis. Participants will have the study protocol explained to them and will consent to the study, agreeing to have the bone marrow aspiration (BMA) and hip injection performed. Prior to any interventions, the participants will complete the baseline patient reported outcomes scores, and blood draw outlined in SOA section 1.3. Inclusion and exclusion criteria will be assessed during screening. Kellgren-Lawrence grade will be determined by blinded radiologists and co-investigators (Drs. Amer Hanano and Carl Winalski). An average score will be taken. In order to blind the patient of the intervention, the triamcinolone group will undergo a "sham" bone needling of the bone cortex to simulate bone marrow harvesting (BMH). The posterior iliac spine will be anesthetized and needled simulating a BMH. Following the needling, the group will then receive a triamcinolone injection. The process of aspirating the bone marrow used has been described by Dr. Friedlis and Dr. Centeno and will be completed under ultrasound guidance and in sterile fashion19. Multiple small draws of maximum 10 cc will be completed from different locations in the posterior superior iliac spine. The procedure as described is safe and been completed in more than 2000 individuals. Three to six passes are completed on each posterior superior iliac spine and a total volume of 60 cc of bone marrow is aspirated. The BMAC group will have bone marrow aspirated using the Emcyte ASPIRE™ needle and subsequently concentrated using the Emcyte PureBMC™ system. Out of the bone aspirated, 60 cc will be utilized for concentration, 1 cc will be utilized by Cleveland Clinic's Florida Research Innovation Center (FRIC), 2 cc will be utilized by Bioscience Research Laboratory (BSR), and 2 cc will be stored in a -80°C biorepository enzyme-linked immunosorbent assay to determine concentrations of IL-1ra and other cytokines The 60 cc of unconcentrated bone marrow will then be concentrated to a total of 8 cc of concentrated bone marrow utilizing the Emcyte PureBMC™ system. Out of these 8 cc, 4 will be injected to the patient and the remainder 4 cc will be utilized for analyses. These are the volumes and respective analyses:

• - 1 cc will be directed to FRIC for flow cytometry.

• - 1.5 cc will be directed to BSR for colony forming units, cell viability, total nucleated cell count as outlined in the subsequent paragaphs, - 1 cc will be sent for 14 day culture.

• - 0.5 cc for endotoxin testing and gram stain.

We will measure endotoxin concentrations utilizing the Charles River Nexgen PTS point of care instrument. The limit of endotoxin for general medical devices is 0.5 EU/mL. We will abide by this limit. Rapid sterility will be assessed using a gram stain, performed by a CLIA certified laboratory at Cleveland Clinic Florida. To ensure patient safety, patient will be considered a screen failure if there is a positive Gram stain or positive endotoxin testing. The injection of the BMAC will not be subsequently injected. The remaining 4 cc will be utilized as the intervention group injectate. The BMAC will be injected as is and will not undergo any manipulation and/or dilution. The 4 cc BMAC dose or 1 cc triamcinolone of 40 mg with 3 cc of lidocaine 1% will be injected into a single affected hip joint under ultrasound guidance. Once the injection has been completed, patient will be monitored for 15 minutes and discharged home. Participants will be instructed to not use ice or anti-inflammatory medications for at least 6 weeks. For pain control following the procedure, the participant will be recommended to use acetaminophen or tramadol depending on the severity. Heat may be applied to the hip joint in case of muscle tightness. Ice should be avoided at the injection site. It may be applied at the site of bone marrow aspiration. Participant will then follow-up in 6 weeks, 3 months, 6 months, and 1 year post-procedure to completed PROs and functional assessment with research staff. Participants will be asked to communicate to the Principal Investigator when anti-inflammatory medications are initiated, if necessary. Following the injections, both groups will resume home exercise program which participants had been completing prior to the injection in a pain free approach.
