Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of subjective therapy evaluation (KOOS questionnaire) compared to baseline | Knee injury and Osteoarthritis Outcome Score (KOOS) to assess pain, other symptoms, activities of daily living (ADL), function in sport and recreation (Sport/Rec) and knee-related Quality of Life (QoL) on a 5-point Likert scale | week 1, week 12, week 24, week 36 | 
| Change of pain intensity compared to baseline (visual analogue scale, VAS) | Evaluation of pain intensity by the patient on a 10 cm VAS-slider. 10 cm equals the worst pain. | week 1, week 12, week 24, week 36 | 
| Change of patient's global assessment (overall impression of clinical OA severity on a numerical rating scale from 0 to 10) | The change of overall subjective symptom severity evaluation on a scale from 0 (very good condition) to 10 (very poor condition). | week 1, week 12, week 24, week 36 | 
| Change of clinical global impression (overall impression of clinical OA severity of the investigator on a numerical rating scale from 0 to 10) | The change of clinical global Impression on a scale from 0 (very good condition) to 10 (very poor condition). | week 1, week 12, week 24, week 36 | 
| Responder rate according to OMERACT-OARSI criteria |  | week 24 | 
| Incidence of treatment-emergent Adverse Events |  | Up to week 36 | 
| Satisfaction scale (subjective satisfaction of patient and investigator with the treatment on a 5 Point likert scale) | Subjective satisfaction on a scale from 1 (very satisfied) to 5 (very unsatisfied) | week 1, week 12, week 24, week 36 |
