Platelet-rich plasma and hyaluronic acid injections are both popular treatments and commonly used for treatment of knee osteoarthritis. Even though there are many studies investigating the effectiveness of these treatments, the results are mostly qualitative. Also there are a few studies comparing these two treatment modalities. In this study the investigators aim to compare these modalities both for self-reported data (pain, physical function) and objective measurement data (femoral cartilage thickness via ultrasonography). Patients with unilateral osteoarthritis/unilateral complaint will be included in the study. Unaffected side will be controls for each group.
This study aims to compare the effects of hyaluronic acid injection and platelet rich plasma injection in terms of pain, physical function and femoral cartilage thickness in short term treatment in patients with knee osteoarthritis.
