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.

Arm Intervention/treatment
Experimental: PRP
one intraoperative application of PRP in the interventional group
Biological: Platelet rich plasma
Other Name: ACP ( Arthrex )

No Intervention: Control
No application of any substance during knee arthroscopy

Primary Outcome Measures :
  1. pain ( VAS ) [ Time Frame: 6 months ]
    measurement of pain using a 100 mm VAS as platelet- rich-plasma demonstrated temporarily analgetic effects up to 6-9 months after application.

Secondary Outcome Measures :
  1. pain ( VAS ) [ Time Frame: 6 weeks, 12 months ]
    To investigate the pain development over the follow up period at the beginning and the end of our trial

  2. knee function (Lysholm-score ) [ Time Frame: 6 weeks, 6 months, 12 months ]
    to determine PRP-related gain of function according to time after application

  3. quality of life ( physical und mental summaries of SF-36 German version ) [ Time Frame: 6 weeks, 6 months and 12 months ]
    to identify a possible effect of PRP application on life quality ( physical and mental summaries )
