Targeting and Filling subchondral bone defects

The Subchondroplasty Procedure is a minimally-invasive, fluoroscopically-assisted procedure that targets and fills subchondral bone defects through the delivery of AccuFill®Bone Substitute Material (BSM), a nanocrystalline, highly porous injectable calcium phosphate (CaP).

The SCP Procedure is usually performed along with arthroscopy for visualization and treatment of findings inside the joint. In some cases, an open or mini-open procedure is necessary for access to the defect.


  • Treats chronic, symptomatic, subchondral bone defects which are the primary cause of joint pain, not the intra-articular tissue.5,6


  • Proprietary minimally-invasive, joint preserving injection of AccuFill BSM which is replaced with new bone during the healing process.1,2
  • Usually performed along with arthroscopy to aid in visualization, the SCP procedure does not inhibit the treatment of other findings inside the hip joint when performed along with arthroscopy. 
  • Typically an outpatient procedure, so patients generally return home the same day.


  • AccuFill BSM sets hard and remodels into the new bone during the healing process.1,2
  • Peer-reviewed data demonstrate sustained pain reduction, improved function and quality of life.3,4
  • SCP Procedure does not preclude future procedures. Should it become necessary, future surgery is still an option.
