Prospective Clinical Study to Evaluate the Safety and Efficacy of Intraarticular Administration of Micro-grafts of Adipose Tissue (Adipo-micro-grafts) in the Treatment of Osteoarthritis of the Trapezium-metacarpal Joint
In Brief
A clinical study evaluating adipose micro-grafts injection for Osteoarthritis and Osteoarthritis Thumbs. Completed, enrolled 25 participants across 1 site.
Detailed Summary
The objective of this interventional study is the Change in the Michigan Hand Questionnaire (MHQ) score over time in subjects with Eaton Littler grade II and III trapeziometacarpal osteoarthritis. The main questions to be answered are: * primary outcomes: Differences in the change in the MHQ scale measured as a reduction in the score result of 12 points within 6 months from preoperative. * secondary outcomes: Change from baseline in hand function measured by grip strength (Gripstrength); Change from baseline in hand function by lateral grip strength (tippinch and tripodpinch); Change in the Visual Analogue Scale (VAS) pain scale before the procedure then after the procedure, at 1, 3 and 6 months; Safety and tolerance of the treatments.

Interventions
Patients were positioned supine, and local anesthesia was administered. A small incision was made to introduce a blunt cannula attached to a Luer-lock 60-cc syringe. Klein sterile solution, containing saline and lidocaine, was injected into the subcutaneous fat layer of either the abdominal or thigh region. Subsequently, approximately 30 mL of adipose tissue was extracted. The collected lipoaspirate was processed under sterile conditions in a closed system using Rigenera® technology (HBW, Turin, Italy). Before injecting, the skin was sterilely dressed, and the injection of 2-3 mL of aMAT was performed into TMC joint with a superolateral approach, under fluoroscopic X-ray guidance and using a disposable 20G needle and a 3 mL Luer-Lock Syringe.
