简要总结
Primary aim of this trial was to assess efficacy three intraarticular injections of platelet lysate when compared to hyaluronic acid. Additional objectives were to compare the treatment groups in terms of a number of functional scales and of number of adverse events.
详细描述
Intra-articular injections of hyaluronic acid are effective in improving symptoms and slow disease progression, but are not able to revert the damage mechanism and trigger cartilage healing.
Growth factors included in PRP could stimulate cartilage repair, normalize synovial fluid viscoelasticity, induce a correction in tissue damage, improve articular function, control pain and ameliorate quality of life.
Primary aim of this trial was to assess, among patients with grade II/III osteoarthrosis of the knee, efficacy (as determined by improvement at MRI 6 months after the first injection) of three intraarticular injections of platelet lysate when compared to hyaluronic acid. Additional objectives were to compare the treatment groups in terms of a number of functional scales (WOMAC, Lysholm, Tegner Knee, Scale, AKS, Lequesne, VAS) and of number of adverse events.

研究组 & 干预措施
Platelet-rich plasma
Patients in the intervention group will receive three autologous PRP plus calcium gluconate (as activator) intraarticular injections at 4-week intervals. Briefly, at the Immunohaematology and Transfusion Service, on each scheduled visit 20 ml of autologous whole blood will be sampled from each patient, 2 ml ACD-A will be added directly the syringe as anticoagulant; finally the vial will be gently centrifuged at 900rpm for 7 minutes. Platelet-rich plasma was collected. The PRP vials plus activator will be immediately shipped to the rehabilitation unit, where intraarticular injection will be performed by an experienced physiatrist.
干预措施: intraarticular injections of platelet lysate (Biological)
hyaluronic acid
Patients in the control group will receive three intraarticular hyaluronic acid (20 mg/2 mL; Hyalgan, Fidia, Abano Terme, Italy) injections at the same intervals, by the same study staff.
干预措施: hyaluronic acid (Drug)
