Description of intervention(s) / exposure
Treatment: Drugs - Tapentadol PR
Experimental: Tapentadol - Tapentadol PR was given orally twice a day. A maximum of 2 oral Tapentadol IR tablets per day, with a minimum of a 4 hour interval between doses, were taken if there were acute pain episodes. The total daily dose of Tapentadol PR and IR were not permitted to exceed 500 mg per day.
Treatment: Drugs: Tapentadol PR
Tapentadol Prolonged Release (PR) Titration and Optimal Dose Period: Starting at 50 mg, 100 mg or 150 mg Tapentadol PR twice daily, adjusting at 50 mg PR steps (upwards or downwards) as necessary to achieve a balance between pain relief and a satisfactory level of tolerability. Participants were not permitted to exceed 500 mg of Tapentadol per day.
Maintenance Period: Participants continuing on the dose established in the previous period.

Western Ontario McMaster Questionnaire (WOMAC) Global Score: WOMAC is measured with a Likert ordinal scale (the participant gives one of 5 possible answers) A higher score indicate that a symptom is bothersome or disabling. The WOMAC is a self-administered questionnaire and has 24 questions: Pain, Stiffness and Physical Function. The possible scores range from 0-20 for pain, 0-8 for stiffness, 0-68 for physical function and these are then summed 0-96 for the global score. A lower score indicates a lower level of symptoms and or disability.

The participant scored the EuroQol-5. This is a five dimensional health state classification. Each dimension is assessed on a 3-point ordinal scale (1=no problems, 2=some problems, 3=extreme problems). The responses to the five EQ-5D dimensions were scored using a utility-weighted algorithm to derive an EQ-5D health status index score between 0 to 1, with 1.00 indicating "full health" and 0 representing dead. The positive values indicate that during the study the health status improved.

EuroQoL-5D Health State Visual Analog Scale (VAS) is a participant rated questionnaire to assess health-related quality of life in terms of a single index value. The VAS component rates current health state on a scale from 0 (worst imaginable health state) to 100 (best imaginable health state); higher scores indicate a better health state. The values indicated represent the change from the baseline, a positive value indicates an improvement.

months before the Screening Visit.
- Presence of conditions other than OA of the reference joint that could confound the
assessment or self-evaluation of pain, e.g., anatomical deformities, significant skin
conditions such as abscess or syndromes with widespread pain such as fibromyalgia.
Subjects with OA at joints other than the reference joint will not be excluded as long
as the reference joint is the source of main pain and disability.

Summary
Brief summary
The main objective of the study is to evaluate the effectiveness, tolerability, and safety of
tapentadol hydrochloride prolonged release (PR) in participants suffering from severe chronic
pain due to osteoarthritis of the knee who are taking WHO Step III analgesics and show lack
of tolerability. This is a clinical effectiveness trial designed to establish a link between
anticipated clinical outcomes and the clinical practice by means of selected measures of
clinical and subject-reported outcome. The trial will compare the effectiveness of previous
analgesic treatment (WHO Step III) with that of tapentadol hydrochloride PR treatment during
defined periods of evaluation.
