On the basis of clinical and radiological diagnosis of OA of the knee,
we treated 223 patients with HA (105 pateints in Group A) and we treated withPRP (118 patients in Group B).

In Group Aa: MRI showed an improvement of 60% (10 pre-treatment and 4 after),VAS improvement of 40% and Womac of 65%;Group Ab: MRI showed an improvement of 29% (7 pre-treatment and 5 after) VAS improvement of 52% and Womac of 42%.Group Ba: MRI showed an improvement of 30% ( 10 pre-treatment and 7 after) VAS improvement 36 % and Womac 35% ;in Group Bb:MRI showed an improvement of 86% (7 pre-treatment and 1 after);VAS improvement of 82% and Womac 60%
