Surgical Applications for Bone Marrow Aspirate Concentrate.

Area of Science:

• Orthopaedic Surgery
• Regenerative Medicine
• Biologics

Background:

• Bone marrow aspirate concentrate (BMAC) is an autologous orthobiologic agent derived from bone marrow.
• It contains mesenchymal stromal cells and platelets, offering potential for tissue repair and symptom management.
• BMAC is gaining attention for its role in treating chondral degeneration and improving orthopaedic outcomes.

Purpose of the Study:

• To review the composition, preparation, and therapeutic potential of BMAC in orthopaedic surgery.
• To evaluate the current evidence regarding BMAC's efficacy in various orthopaedic conditions.
• To highlight the biological mechanisms underlying BMAC's regenerative capabilities.

Main Methods:

• Literature review of studies investigating BMAC in orthopaedic applications.
• Analysis of BMAC's cellular components and their biological functions.
• Synthesis of findings from clinical studies on BMAC for cartilage repair, labral repair, and rotator cuff repair.

Main Results:

• BMAC demonstrated potential in reducing revision rates for rotator cuff repair.
• Studies indicated improved functional outcomes after arthroscopic acetabular labral repair with BMAC.
• BMAC use was associated with significant pain reduction in patients with knee cartilage defects.

Conclusions:

• BMAC shows promise as an effective adjuvant therapy in specific orthopaedic surgical scenarios.
• Mesenchymal stromal cells and platelets in BMAC contribute to cartilage repair and tissue healing.
• While promising, further randomized controlled trials are necessary to establish the mid- and long-term efficacy of BMAC.
