Evaluation of the Efficacy of an Intra-articular Injection of Autologous Microfat Combined With Autologous Platelet-enriched Plasma in the Treatment of Radiocarpal Osteoarthritis: a Randomized Controlled Non-inferiority Trial Versus Total Wrist Denervation (Established Standard Treatment). (AMIPREP-2)
Evaluation of the Efficacy of an Intra-articular Injection of Autologous Microfat Combined With Autologous Platelet-enriched Plasma in the Treatment of Radiocarpal Osteoarthritis: a Randomized Controlled Non-inferiority Trial Versus Total Wrist Denervation.
This is a phase II, prospective, comparative, randomized, single-center, open-label, parallel-group therapeutic trial.
It is a non-inferiority trial to establish the efficacy of intra-articular injection of autologous microfat and PRP at the wrist in patients suffering from radiocarpal osteoarthritis in reference to wrist denervation.

Detailed Description
The main objective is to demonstrate the non-inferiority of the efficacy of intra-articular injection of autologous microfat and PRP in patients suffering from radiocarpal osteoarthritis resistant to medical treatment on pain evaluated by the visual analog scale (VAS) at 6 months in comparison with total denervation of the wrist (reference treatment).
Secondary objectives are:
- To assess the safety of the study treatment at D7, M3, M6, M12, compared to the reference treatment group: Adverse events and post-operative follow-up data.
- To assess the non-inferiority of the study treatment compared to the reference treatment on the secondary efficacy criteria.
- Evaluate the effectiveness of the treatment under study.
- Evaluate patient satisfaction.
- To investigate the existence of a relationship between the characteristics of the injected products and the clinical improvement and to describe the characteristics of the responder and non-responder patients. The responder patient was characterized by an improvement of the VAS at 6 months superior to the minimal clinically significant difference fixed at 14 points.
- To evaluate the improvement of cartilage relaxation time on high-resolution T2 gradient echo and Turbo Spin Echo 3T MRI sequences at 6 months in patients in the "study treatment" group.

Day 7, 3 Months and 1 Year
|
Combined assessment of function and pain by the PRWE score
Time Frame: 3 Months, 6 Months and 1 Year
|
The PRWE (Patient-Rated Wrist Evaluation) is a specific wrist function and pain assessment score.
The questionnaire consists of 15 items, 5 of which focus on pain (50 points) and 10 on wrist function (100 points).
We will use the combined score in which the total points for wrist function are divided by 2 and added to the pain score to obtain a total score out of 100 points.
|
3 Months, 6 Months and 1 Year
|
Assessment of upper limb function by the DASH score
Time Frame: 3 Months, 6 Months and 1 Year
|
The DASH (Disabilities of the Arm, Shoulder and Hand) is a subjective self-assessment questionnaire of the overall functional capacity of both upper limbs.
The questionnaire consists of 30 questions covering difficulty with specific activities of daily living, social relationships, and specific symptoms: pain, strength, mobility and sleep.
The overall score is presented as a score out of 100 by the following calculation method: [(sum of n responses)-1] x 25n.
The score is only valid if 90% of the questions have been filled in by the patient (i.e. 3 missing values at most).
