Microwave ablation of synovial hypertrophy in recurrent monoarthritis: the results of extended cohort and long-term follow-up
Authors' conclusion
As a less invasive technique compared with the surgical approach, MWA of synovial hypertrophy showed significant clinical improvement in RM safely.
Study context
- Population
- Patients with medical treatment-resistant recurrent monoarthritis (RM) associated with different inflammatory diseases; knee joints; aged 22–71 years24 knee joints
- Exposure
- Before vs after microwave ablation (MWA) of synovial hypertrophy
- Outcome
- IA aspiration (IAA) need
Main finding
As reported in the abstract
Overall IAA count (per month)
P < 0.001
Observational data: associations, not effects.
Further findings
Functional disability score, before vs after MWA
- Median score improved from 9 to 1
- P < 0.00001
Pain score, before vs after MWA
- Median score improved from 9 to 1
- P < 0.00001
Synovial hypertrophy size on MRI · especially after the 6th month
- Significant regression in synovial hypertrophy size
Repeat MWA sessions
- Second MWA session needed
- 3 patients
- Third session needed
- 1 patient
Safety
Complications during procedure or follow-up
- No complication observed
