Use of Adipose Derived Regenerative Cells in Bilateral Femoral Head Osteonecrosis

Approximately 5 mls of lactated ringers will be injected after decompression into the hip that does not receive adipose derived regenerative cells.

The Celution 800/GP System will be used for the preparation of adipose derived regenerative cells from lipoaspirate. The adipose derived regenerative cells will then be transplanted into the hip, post decompression.

Subjects in this arm will have Adipose Derived Regenerative Cells (ADRC)harvested through autologous liposuction and processed outside the body using The Celution 800/GP System (Cytori Therapeutics) before having approximately 5 mls. of ADRCs transplanted into the femoral head after standard of care hip decompression.
