- 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.
