Summary
Recent works in interventional radiology have shown interesting results in the treatment of musculoskeletal inflammatory sites by arterial embolization. Supra-selective arterial embolization has been successfully developed by Dr. Okuno (Japan) to manage moderate to severe knee osteoarthritis. Also, inflammation of the surgical site mediated via geniculate arteries is a major cause for persistent chronic post-operative gonalgia.
Description
Hypothesis: Selective arterial embolization of persistent geniculate arteries could reduce chronic post-operative gonalgia after TKA with minimally invasive approach.
Objective: To evaluate the feasibility of selective arterial embolization of persistent geniculate arteries to reduce chronic post-operative gonalgia after TKA.
Material and methods: This study is a single-center, prospective, feasibility study. Patients will be recruited after rheumatology consultation for chronic post-operative gonalgia, more than 6 months after TKA for moderate to severe gonarthrosis. Eligible patients are adults with moderate to severe chronic post-operative gonalgia (Visual Analysis Scale (VAS) > 50mm) and degraded life quality (assessed by SF36 score), despite at least 3 months of optimal medical treatment. Non-inclusion criteria are mainly other rheumatologic or orthopedic severe diseases, severe surgical complications. Under local anesthesia, with homolateral antegrade femoral access, patient will undergo selective arterial embolization of persistent and aberrant peri-prosthetic arteries using HydroPearl 200m Mircospheres. Follow-up consultations will be scheduled at D1, M1, M3, M6 and M12. For a significance level of =0.05 and power of 80% we require a cohort of 24 patients.
