Brief Title  ICMJE Clinical Study of Pain Reduction by Peri-arthroscopic PRP Application in Knee Degeneration
Official Title  ICMJE Effect of Platelet Rich Plasma ( PRP ) Applied During Knee Arthroscopy on Pain, Function and Quality of Life - A RCT With a Follow up of 12 Months
Brief Summary The purpose of this study is to investigate reduction of pain, gain of function and improvement of life quality by intraoperative applied platelet- rich- plasma ( PRP ) during knee arthroscopy for degeneration and osteoarthritis OA by conducting a randomized- controlled, double-blinded trial ( RCT ) including 58 patients with a follow up of 12 months and pain, assessed by Visual- Analogue Scale (VAS) after 6 months as primary endpoint.
