Real-life Assessment of the Safety and Performance of the SYNOVIUM HCS Device

Recruiting
Conditions
Gonarthrosis
Registration Number
NCT06087705
Lead Sponsor
LCA Pharmaceutical
Brief Summary

Patients who are to benefit from an injection of SYNOVIUM HCS as part of their care will be offered to participate in this study. Patients will need to sign a consent form to participate. Prior to SYNOVIUM HCS injection, patients will be asked a series of questions regarding their pain and disability. Data collected during follow-up visits can be compared to pre-injection data.

Detailed Description

Inclusion period: 6 months

Follow-up period:

* 6-month follow-up, after intra-articular injection with extension

* 1 single syringe of SYNOVIUM HCS (3 mL),

* Controls scheduled at 1 week, 1, 3, 6 months and up to 1 year

* Additional control (single) in the event of leaving the study if this takes place outside the scheduled visit dates and before 1 year, for medical reasons

* Duration of the study: Overall time estimated at 18 months

* In this open-label CI, the group itself is used as a control, by comparing the scores on inclusion with those of the various control visits.

Primary Outcome Measures
NameTimeMethod
device performance6 months

evolution of the pain sub-score of the WOMAC (universities of Western Ontario and McMaster) index (A). The higher the score, the more the knee osteoarthritis has a functional impact.

Secondary Outcome Measures
NameTimeMethod
responder patients1 year

Rate of responder patients according to the OMERACT-OARSI criteria (to the treatment, in knee osteoarthritis) (0% (no responder) to 100% (all responder))

Evolution of the pain1 year

Evolution of the pain sub-score (WOMAC A)(universities of Western Ontario and McMaster) index (A). (Higher scores mean worse outcome)

Stiffness1 year

Evolution of the stiffness sub-score (WOMAC B) (universities of Western Ontario and McMaster) index (B). (Higher scores mean worse outcome)

Impact of the injection on concomitant treatments1 year

Recording of the consumption of analgesics and NSAIDs

Investigator's general assessment1 year

General assessment by the investigator at the end of the study. (Likert scale 0-3, higher scores mean better outcome)

Complication1 year

complication rate

recovery of autonomy1 year

Evolution of the disability according to the patient (Likert scale 0-10, higher scores mean better outcome)

Function1 year

Evolution of the function sub-score (WOMAC C) (universities of Western Ontario and McMaster) index (C). (Higher scores mean worse outcome)

long-term performance of the SYNOVIUM HCS device1 year

Rate of patients having reached 1 year, without intervention on the knee concerned
