Subchondroplasty (SCP®)

Knee sparing surgery (Subchondroplasty) is a minimally-invasive, fluoroscopically-assisted procedure that targets and fills subchondral bone defects with a hard-setting bone substitute material that is replaced with new bone during the healing process.  SCP® is usually performed with arthroscopy for joint visualization and treatment.  This procedure helps with pain and prevents Osteoarthritis, and can eliminate or postpone the need for Total Knee Replacement.

The causes of a of a subchondral bone defect (Bone Marrow Lesion) defect are not precisely known.  Sometimes, these defects are a from a bone injury that doesn’t heal correctly.  Other times, it may be a stress reaction that forms from overuse or poor joint mechanics.

Bone Marrow Lesion factors include:

  • Obesity and poor diet are thought to increase the likelihood of developing
  • More commonly found in middle-aged patients than in younger patients
  • Patients with poor joint alignment are more likely to develop
  • Adults who quickly increase activity may develop

Dr. Scott Sigman will base a diagnosis of a subchondral bone defect (Bone Marrow Lesion) on your clinical history, physical exam and MRI results to see if the SCP® procedure is right for you.


Dr. Scott Sigman uses EXPAREL to reduce opioid reliance and consumption.  EXPAREL can provide a non-opioid pain control in the first few days after surgery when patient’s postsurgical pain is the highest.  When using EXPAREL, there is no need for catheters, pumps, or other delivery devices.

Dr. Scott Sigman is a consultant for Pacira Pharmaceuticals, Inc., and has partnered with them on an initiative to use opioid alternatives in the surgical setting.
