Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Prospective single-masked (study participant will be masked), randomized controlled trial to examine the influence of BMAC on patient-reported outcomes (PROs) in patients with primary knee osteoarthritis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to examine the influence of BMAC on patient-reported outcomes (PROs) in patients with primary knee osteoarthritis and compare that to patients receiving corticosteroid injections with six-month follow-up.

All patients who sign the consent form will be enrolled in the study and randomized to one of the two treatment arms. This study will aim to recruit and enroll a total of 100 patients (50 per group). Treatment arms include BMAC injections (ARM1) and corticosteroid injections (ARM 2). Patients in the corticosteroid injection group (ARM 2) will receive a sham incision. Follow-up will be up to six months (12-months if crossover (ARM 3)).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Autologous (from subject to self) bone marrow aspirate concentrate (BMAC) injections

Autologous bone marrow aspirate concentrate (BMAC) will be removed from the subject knee body with a needle, processed and concentrated by an FDA-approved centrifuge (separator) system. The concentrated cells will be injected into the subject knee. "Autologous" means that the subject is receiving back their own cells that were collected.

Group Type EXPERIMENTAL

Autologous bone marrow aspirate concentrate (BMAC)

Intervention Type OTHER

Bone marrow aspirate concentrate BMAC is a biologically substance harvested from a patient for autologous use. Bone marrow aspirate concentrate (BMAC) has been determined by the FDA to be a minimally manipulated biologic prepared for autologous use and does not require premarket FDA approval for clinical use.

Corticosteroid injection

Corticosteroid injection group (ARM 2) will receive a sham incision.

Group Type ACTIVE_COMPARATOR

Corticosteroid injections

Intervention Type DRUG

Current standard of treatment for OA of the knee is corticosteroid injection.

Crossover Group

Any patient in the corticosteroid injection group that shows no improvement in pain after 24 weeks (12 month follow-up if crossover), per physician discretion, will be allowed crossover to the BMAC injection group (ARM 3).

Group Type OTHER

Crossover Autologous bone marrow aspirate concentrate (BMAC)

Intervention Type OTHER

Subjects who participate in this study and who are randomized to receive the BMAC may experience decreased pain and increased functionality after the injection compared to those that receive a corticosteroid injection. As such, participants who continue to have pain after a corticosteroid injection will be allowed to crossover to a BMAC injection at 24 weeks or 6 months post-surgery.(ARM 3)
