Grade 4 knee osteoarthritis according to the Kellgren-Lawrence scale~2. History of intraarticular viscosupplementation or steroid injection in the target knee in the past 6 months at the time of the baseline visit or intraarticular injection planned during the trial~3. History of arthroscopic surgery in the target knee in the past 12 months at the time of presentation to the clinic or planned surgery during the trial period (e.g., scheduled for/awaiting arthroscopy or a knee replacement procedure)~4. Bilateral knee osteoarthritis (unless the contralateral knee involvement is limited to radiographic osteoarthritis and not symptomatic)~5. Ipsilateral (same side) or contralateral (opposite side) symptomatic osteoarthritis of hip or ankle~6. Clinically apparent tense effusion or other acute inflammation of the target knee at the time of presentation to the clinic~7. Active infection of either lower extremity such as cellulitis or any skin disease or infection in the area where BMAC is aspirated, blood is drawn, or an injection is given~8. History of diagnosis of any of the following: 1) septic osteoarthritis of any joint, 2) inflammatory arthropathy such as rheumatoid arthritis, gout, pseudogout, lupus, crystalline arthropathy, chondrocalcinosis and other rheumatology diagnoses~9.

Study Arms:
- BMAC injection and PRP injection (Type: EXPERIMENTAL): Injection of bone marrow aspirate concentrate (BMAC) withdrawn from a bone near the hip into the knee joint (intra-articular) immediately followed by an injection of platelet-rich plasma (PRP) into the knee joint.
- Gel-One® hyaluronate injection (Type: ACTIVE_COMPARATOR): Gel-One® is an hyaluronate gel used in the treatment of knee osteoarthritis by injection into the knee joint (intra-articular).

Based on this trial design, predict the completion outcome and termination type (if applicable).
