简要总结

Recently an articular cartilage repair has been given much attention in the orthopaedic field. Cartilage regeneration capacity is very limited. Optimal approach seems to be a delivery of natural growth factors. Autologous platelet-rich plasma (PRP) contains proliferative and chemoattractant growth factors. The objective of the present study was to determine if PRP can increase tibiofemoral cartilage regeneration and improve knee function.

详细描述

Fifty consecutive and strictly selected patients, affected by Grade II or III chondromalacia, underwent one year treatment (9 injections) with autologous PRP in a liquid form with 2,0 to 2,5-fold platelets concentration. Outcome measures included hte Lysholm, Tegner, IKDC, and Cincinnati scores. Magnetic resonance imaging was used to evaluate cartilage thickness and degree of degeneration.

结局指标

主要结局

Change of the width of cartilage in the knee joint assessed by magnetic resonance imaging before and after nine Platelets Rich Plasma injections.

时间窗: 11 months after first Platelets Rich Plasma injection

50 patients with Grade II or III chondromalatia in the knee joint, underwent one year treatment with autologous Platelets Rich Plasma. Magnetic resonance imaging was used to evaluate cartilage thickness and degree of degeneration before and after the treatement of nine Platelets Rich Plasma injection.

次要结局

  • Changes in the subjective and objective clinical outcomes before and after nine Platelets Rich Plasma injections.(11 months)
