Subchondroplasty Procedure

  • A new technique to treat the cause of pain in osteoarthritis (which is due to a bone marrow abnormality in the area under the articular cartilage loss)
  • Bone marrow abnormality occurs as it is unable to take the weight/stress and becomes permanently damaged
  • MRI picks up the abnormality in the bone marrow which is called bone marrow oedema (lesion)
  • Bone marrow lesion must be present for 3 months so a repeat scan may be required
  • Technique involves decompressing this area and injecting Calcium Phosphate filler under X-Ray control
  • Arthroscopy is undertaken at the same time to ensure no filler leakage into the joint
  • Pain may initially increase but then reduces within a week and patient avoids or delays the requirement for joint replacement
  • Early results are very good with over 100,000 cases performed in the US already. Paul performed the first cases and has the largest experience in London.
