Outcome Measures

Primary Outcomes (1)

  • Visual pain scale score

    Visual pain scale score (min 0-max 10), higher scores indicate better results

    Visual pain scale score (min 0-max 10) will be measured at the beginning ofthe study, 1 week, 1month and 3 months after the injection.

Study Arms (2)

PRP group

EXPERIMENTAL

patients with knee osteoarthritis who will be injected with autologous PRP

Drug: Autologous Platelet-Rich Plasma (PRP)

conditioned serum group

EXPERIMENTAL

patients with knee osteoarthritis who will be injected with autologous conditioned serum

Drug: Conditioned serum (CS)

Interventions

Autologous Platelet-Rich Plasma (PRP) will be injected intra-articularly in patients with knee osteoarthritis

PRP group

Autologous conditionedserum (CS) will be injected intra-articularly in patients with knee osteoarthritis

conditioned serum group
