About

This is a non-surgical trial comparing the clinical and functional outcomes of patients with osteoarthritis treated with Intra-articular injection of Micro Fragmented Adipose Tissue versus conventional therapy of intra-articular injection of corticosteroid.

Full description

This study will be a randomized controlled trial to compare outcomes between intra-articular injection of Micro Fragmented Adipose Tissue and intra-articular injection of corticosteroid in patients with mild to moderate osteoarthritis of the knee. Micro Fragmented Adipose Tissue will be harvested at the subcutaneous tissue by lipoaspiration. Once fat tissue is obtained, it will be processed with minimal manipulation in the clinic room.

To be considered for participation in this study, patients must have radiographic evidence of mild to moderate osteoarthritis of medial and/or lateral weight-bearing compartments (Kellgren-Lawrence Grade 2 or 3). In addition, patients must meet several inclusion/exclusion criteria to be randomized and included in this study.

Enrollment: 40 patients

Sex: All

Ages: 35 to 75 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Age between 35 and 75 years-old

• Capable of providing informed consent
• Able to complete online, in-person or phone surveys for the purposes of follow-up
• Capable of understanding pre- and post-procedure care instructions
• Ambulatory at baseline
• Previous trial and failure of conservative therapy consisting of a minimum of 6 weeks of physical therapy and trial of anti-inflammatory medications if not contraindicated, with or without concomitant bracing and/or injections.

Exclusion criteria

• Age < 35 or > 75 years old
• Radiographs demonstrating either no, little or severe osteoarthritis (Kellgren-Lawrence Grade 0, 1 )
• Prior total or partial joint replacement surgery or a surgery involving cartilage regeneration (microfracture, ACI, etc)
• Previous cortisone and/or Hyaluronic acid intra-articular injection within the last 3 months
• Co-morbidity with rheumatologic condition, inflammatory arthritis
• Currently undergoing immunomodulatory therapy
• Uncontrolled endocrine disorder
• BMI >35
• Current diagnosis of osteomyelitis, human immunodeficiency virus (HIV-1, -2) and/or hepatitis C (HCV), infection and poorly controlled diabetes (HgA1C >7.0)
• Pregnancy or planned pregnancy

• Patient scheduled to undergo any concomitant surgical procedures.
• Coagulopathy or anticoagulant treatment
• Chronic pain involving multiple body parts or opioid medication management
