Brief Summary
The aim of this study is to use gold particles as a model compound to modulate specifically and selectively the function of macrophages and mast cells and investigate how this modulates pain and pain sensitization in the osteoarthritic knee assessed by mechanistic pain assessment technologies

Study Arms (1)
Gold
EXPERIMENTALApproximately 72000, 20-40 my-meter diameter, sterilised gold particles (=20 mg) will be provided in vials (The Berlock® Gold Implants).
Interventions
Approximately 72000, 20-40 my-meter diameter, sterilised gold particles (=20 mg) will be provided in vials (The Berlock® Gold Implants). 5-10 ml of synovial fluid is aspirated (20G needle) from most affected OA-knee. The vial of gold particles are mixed with the synovial fluid, and the mix of gold and synovial fluid is injected intra-articularly into the patients knee.
Eligibility Criteria
You may qualify if:
- Knee OA diagnosed based on the American College of Rheumatology criteria, KL (Kellgren-Lawrence) X-ray grade ≧ 2, pain for \> 3months, maximal pain intensity VAS (visual analogue scale) ≧ 5 (0-10 scale) for the most painful knee during the last week. Knee joint effusion that can be aspirated
You may not qualify if:
- Pregnancy
- Drug addiction defined as the use of cannabis, opioids or other drugs
- Previous neurologic, musculoskeletal or mental illnesses
- Lack of ability to cooperate
- Current use of medications that may affect the trial e.g. analgesics, anti-inflammatory drugs

- Past history of a chronic pain condition
- Participation in other pain trials throughout the study period
