Brief Summary:
The purpose of this study is to investigate the safety and effectiveness of bone marrow aspirate concentrate (BMAC) in patients with moderate to severe osteoarthritis of the knee. BMAC provides a rich source of mesenchymal stem cells (MSCs) and is a stem cell-based therapy that has been reported to preserve or improve the structure of joints. The Angel System is the device used in this study to concentrate bone marrow from the patient and is intended to separate a mixture of blood and bone marrow and collect plasma rich platelets preoperative to a surgical procedure. The goal of this study is to identify whether BMAC can be an effective and safe treatment for patients with osteoarthritis of the knee.

Condition or disease Intervention/treatment Phase
Osteo Arthritis Knee Biological: Bone Marrow Aspirate Concentrate Device: Angel Concentrated Platelet Rich Plasma (cPRP) System Not Applicable

Detailed Description:
This is a pilot open-label, non-randomized, single institution study of BMAC administration in patient's with moderate to severe osteoarthritis of the knee who will undergo total knee replacement. Several weeks prior to total knee replacement, patients will have a sample of bone marrow taken from their pelvic region and concentrated using an investigational device called the Arthrex Angel Concentrated Platelet Rich Plasma (cPRP) System also known as the Angel System. The concentrated bone marrow will be immediately delivered back to the patient arthroscopically to the knee of interest. Blood and tissues samples will be collected at scheduled visits for molecular and histological analysis. Adverse events will be monitored throughout the trial. Assessment of healing will be performed by physical exam and standardized questionnaires related to the health of the patient.

Arm Intervention/treatment
Experimental: Bone marrow aspiration concentrate using the Angel System

Bone marrow aspirate concentrate (BMAC) will be administered via injection to the knee of interest on day 14 of the study.

Bone marrow aspiration will be concentrated using the Angel System.

Biological: Bone Marrow Aspirate Concentrate
Aspiration of bone marrow will be collected from the patient's pelvic bone region and subsequently concentrated with the Angel Concentrated Platelet Rich Plasma (cPRP) System.
Other Name: BMAC

Device: Angel Concentrated Platelet Rich Plasma (cPRP) System
Aspiration of bone marrow will be collected from the patient's pelvic bone region and subsequently concentrated with the Angel Concentrated Platelet Rich Plasma (cPRP) System.
Other Name: The Angel System




Primary Outcome Measures :
  1. Patients with at least one severe adverse event [ Time Frame: End of Study (12 months) ]
    The number of life-threatening severe adverse events as determined by the standard FDA guidelines for adverse events that are deemed to be related to autologous BMAC concentrated by the Angel System and delivered via intra-articular injection into the knee.


Secondary Outcome Measures :
  1. Structural change in knee from baseline measured by the VAS (Visual Analog Scale) in the American College of Rheumatology/Knee Osteoarthritis Assessment Scale (ACR/KOAS). [ Time Frame: End of study (12 months) ]
    The VAS ranges from 0 to 100 with 0 indicating no damage and higher scores indicating more severe damage.

  2. Self reported health from baseline through end of study measured by the 36-Item Short Form Survey Instrument (SF-36) Health Survey and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). [ Time Frame: End of study (12 months) ]
    SF-36 scores are measured via ranges from 0 to 100.


Other Outcome Measures:
  1. Rheumatic disease characterization [ Time Frame: End of study (12 months) ]
    Biological samples (blood, urine, synovial tissue) are characterized via molecular and histological analysis.
