Brief summary
The purpose of this study is to determine the clinical response to autologous bone marrow aspirate concentrate (BMAC) and platelet-rich plasma (PRP) injections for knee osteoarthritis with respect to pain, function, and quality of life at up to 1 year following the intervention. Specifically, the clinical response will be compared to baseline and a control group treated with a Gel-One® hyaluronate injection to the target knee.
Interventions
60mL of bone marrow will be collected from a bone near the hip. Approximately 5-6mL of the bone marrow aspirate concentrate is then used for injection, under ultrasound guidance, into the target knee by the study physician.
60mL of venous blood will be withdrawn from either arm. Approximately 4-5 ml of platelet-rich plasma will be introduced under ultrasound guidance to the subject's target knee by the study physician.
Patients will receive a single injection of Gel-One® (3 ml syringe of Gel-One® - 1% solution \[10 mg/mL\], 30mg total hyaluronan) into the target knee. Injections will be performed by the study physician under real-time dynamic ultrasound guidance.

Each subscale produces a raw score that is converted to a T score such that an average patient in the United States would have a subscale T score of 50 with a standard deviation of 10 points (Global Health: A Brief Guide to the PROMIS® Global Health Instruments, 2017). A score higher than the mean indicates a more desirable score, and vice versa. A positive change score indicates an improvement, while a negative change score indicates a decline in score value. |

Recruitment details
Number of participants to be treated was capped at 30 participants. However, the approved protocol allowed enrollment of up to 45 participants to achieve a treatment group of 30 participants.
Pre-assignment details
Based on the recruitment details stated, if a participant enrolled but subsequently withdrew or was withdrawn prior to treatment, another participant was enrolled in order to achieve a number of 30 participants who were treated within the study. Per protocol, consented patients could include up to 45 if needed to achieve 30 treated participants.
