IntraOsseous BioPlasty™ (IOBP) technique is the treatment used for bone pathologies resulting from acute or chronic injury, including bone marrow lesions and spontaneous osteonecrosis of the knee (SONK). Arthrex^® offers options for the treatment of these pathologies by performing a core decompression of the lesion, and a direct application of concentrated bone marrow aspirate prepared using the Angel^® BMC Kit.
