Osteoarthritis, Knee, Synovitis of Knee
Conditions
Brief summary
To determine whether platelet-rich-plasma (PRP) or HA (hyaluronic acid)injection into synovitis in osteoarthritis(OA) knee can achieve improvement in knee function and reduce synovitis.
Detailed description
Methods: sixty patients with OA knee having unilateral or bilateral synovitis validated by ultrasound (N=40) were studied. All the patients were randomized to receive PRP (N=40) or Hyaluronic acid(HA)(N=40) injection twice at 2-week intervals; Clinical assessments were performed using a visual analog scale(VAS) and The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC index) before injection at baseline, 4 weeks(first evaluation) and 12 weeks(secondary evaluation). Imaging evaluation based on color Doppler ultrasound(CDUS) and the depth of synovial fluid accumulation ,and the width of synovial hypertrophy was performed simultaneously.
Interventions
The amount of PPR was about 4-5 cc
HA was 2.5cc
