PRP Therapy for Knee Osteoarthritis: Regenerative Orthopedics in Clinical Practice
Knee osteoarthritis remains one of the most prevalent degenerative joint disorders worldwide, significantly impacting mobility and quality of life. Conventional management strategies—such as analgesics, corticosteroids, and hyaluronic acid injections—primarily address symptoms without modifying disease progression. PRP therapy in orthopedics introduces a regenerative approach that targets the biological mechanisms underlying cartilage degeneration.
PRP for knee osteoarthritis works by delivering a concentrated source of autologous growth factors directly into the joint environment. These growth factors modulate inflammatory pathways, stimulate chondrocyte activity, and enhance synovial fluid quality. Unlike corticosteroids, PRP does not inhibit tissue repair; instead, it promotes cartilage homeostasis and joint microenvironment restoration.
Clinical studies demonstrate that PRP injections reduce pain, improve joint function, and slow degenerative changes, particularly in early to moderate osteoarthritis. High-purity PRP prepared using CE Marked Class IIb systems ensures consistent platelet recovery exceeding 4 million platelets per dose, which correlates with superior clinical outcomes.
PRP therapy for knee osteoarthritis represents a shift from palliative care toward biologically driven joint preservation. Its integration into orthopedic practice supports long-term functional improvement while minimizing reliance on surgical intervention.
