NCT03850392

Brief Summary

47 patients with non-septic knee arthritis were treated by local ice (30 min) or cold CO2 (2 min) twice at an 8 hour-interval for 1 day. The synovial fluid was collected just before the first cold application then 24 hours later. Cytokine, VEGF, NF-kB, PG-E2 levels were assessed in the synovial fluid before/after treatment. Contralateral arthritic knees were used as paired controls when possible.

Study Arms (3)

ice

ACTIVE COMPARATOR

16 knee arthritis patients treated by local ice (Thermogel®, Artsana, Grandate, Italy - 30 minutes application - twice within one single day). Just before the first cold application, at 9 a.m., and 24 hours later (day=1 at 9 a.m), an arthrocentesis was performed. Standard analyses were performed on the synovial fluid (bacteriology, cytology and microcrystal microscopic assessment). Furthermore, a part of the synovial fluid was centrifuged then frozen at -80°C. For the second arthrocentesis, after the synovial fluid was gathered for the same analyses, an intra-joint corticosteroid injection (Triamcinolone, HEXATRIONE®,Ethypharm, Saint-Cloud, France) was performed before removing the needle.

Device: cryotherapy (Thermogel - Artsana or Cryo+ - Cryonic)

CO2

ACTIVE COMPARATOR

16 knee arthritis patients treated by local hyperbaric cold CO2 at -78°C (Cryo+®, Cryonic, Salins-les-Bains, France - 2 minutes-applied twice within one single day). Just before the first cold application, at 9 a.m., and 24 hours later (day=1 at 9 a.m), an arthrocentesis was performed. Standard analyses were performed on the synovial fluid (bacteriology, cytology and microcrystal microscopic assessment). Furthermore, a part of the synovial fluid was centrifuged then frozen at -80°C. For the second arthrocentesis, after the synovial fluid was gathered for the same analyses, an intra-joint corticosteroid injection (Triamcinolone, HEXATRIONE®, Ethypharm, Saint-Cloud, France) was performed before removing the needle.

Device: cryotherapy (Thermogel - Artsana or Cryo+ - Cryonic)

contralateral non-treated knees

NO INTERVENTION

16 contralateral arthritic knees : the synovial fluid was collected and analysed according to the same procedure but no cold treatment was applied (while the corresponding contralateral arthritic knees were treated by ice) : At 9 a.m., and 24 hours later (day=1 at 9 a.m), an arthrocentesis was performed. Standard analyses were performed on the synovial fluid (bacteriology, cytology and microcrystal microscopic assessment). Furthermore, a part of the synovial fluid was centrifuged then frozen at -80°C. For the second arthrocentesis, after the synovial fluid was gathered for the same analyses, an intra-joint corticosteroid injection (Triamcinolone, HEXATRIONE®,Ethypharm, Saint-Cloud, France) was performed before removing the needle.
