BMAC therapy uses concentrated stem cells and growth factors harvested from your own bone marrow to promote tissue regeneration and healing. The bone marrow aspirate contains mesenchymal stem cells that can differentiate into cartilage, bone, tendon, and other musculoskeletal tissues.
Conditions treated include moderate-to-severe knee osteoarthritis, avascular necrosis (early stages), cartilage defects, chronic tendon injuries unresponsive to PRP, and degenerative disc disease.
The procedure takes 60-90 minutes under local anesthesia. BMAC is typically used for more severe conditions where PRP alone has been insufficient. Relief typically lasts 12-24+ months.
Bone marrow is aspirated from the iliac crest (hip bone) using a specialized needle under local anesthesia. The aspirate is processed in a centrifuge to concentrate the stem cell fraction, which is then injected into the damaged tissue under ultrasound guidance.
The concentrated stem cells and growth factors initiate a powerful healing response, promoting tissue regeneration, reducing inflammation, and improving function. The mesenchymal stem cells in BMAC have the ability to differentiate into multiple tissue types, making them particularly valuable for cartilage repair and joint preservation.
The procedure begins with bone marrow aspiration from the hip, which takes approximately 10-15 minutes. The aspirate is then processed for about 15-20 minutes to concentrate the stem cell fraction. Finally, the BMAC is injected into the target tissue under ultrasound guidance.
Patients typically experience soreness at the hip aspiration site for 2-5 days and mild inflammation at the injection site for 1-2 weeks. Anti-inflammatory medications should be avoided as they may interfere with the healing process.
Activity restrictions depend on the treated area but typically include avoiding strenuous activity for 4-6 weeks. A graduated physical therapy program is essential for optimal outcomes. Most patients can return to daily activities within 1-2 weeks.
Improvement is gradual, with many patients noticing progressive benefit over 6-12 months as tissue regeneration continues.
BMAC is indicated for patients with moderate-to-severe osteoarthritis or tissue damage who have failed conservative treatments. Contraindications include active infection, bone marrow disorders, and certain medical conditions that affect stem cell quality or quantity.
