What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in WOMAC™ Pain	Knee joint pain discomfort assessed with the validated Western Ontario and McMaster University questionnaire (WOMAC) using its visual analogue scale version (VAS). The WOMAC VA 3.1 Pain subscore (WOMAC A) ranges from 0 to 100 mm (averaging five VAS 0-100 mm) with higher scores indicating more pain.	12-weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in WOMAC™ Stiffness	Knee joint stiffness assessed with the validated Western Ontario and McMaster University questionnaire (WOMAC) using its visual analogue scale version (VAS). The WOMAC VA 3.1 Stiffness subscore (WOMAC B) ranges from 0 to 100 mm (averaging two VAS 0-100 mm) with higher scores indicating more stiffness.	12-weeks
Change in WOMAC™ Physical function	Knee joint physical function assessed with the validated Western Ontario and McMaster University questionnaire (WOMAC) using its visual analogue scale version (VAS). The WOMAC VA 3.1 Physical function subscore (WOMAC C) ranges from 0 to 100 mm (averaging seventeen VAS 0-100 mm) with higher scores indicating more stiffness.	12-weeks
Change in WOMAC™ Global Index	Knee joint global discomfort assessed through the sum of WOMAC A (pain), WOMAC B (stiffness) and WOMAC C (physical function) subscores. The WOMAC Global Index score ranges from 0 to 2400 mm (summing up twenty-four VAS 0-100 mm), with higher scores indicating higher disease burden.	12-weeks
Pain intensity at rest	The pain intensity at rest is assessed using a VAS ranging from 0 to 100 mm, with higher scores indicating more pain.	12-weeks
Pain intensity while walking	The pain intensity while walking is assessed using a VAS ranging from 0 to 100 mm, with higher scores indicating more pain.	12-weeks
"Patient Global Assessment" (PGA)	The "Patient Global Assessment" (PGA) is the global assessment on joint discomfort and is assessed using a VAS ranging from 0 to 100 mm, with higher scores indicating more pain.	12-weeks
OMERACT-OARSI criteria	Evaluation of the response to supplementation	12-weeks
30s Chair Stand Physical Performance	Evaluation of the maximum number of chair stand repetitions possible in a 30 second period. Scoring results in a wide range of skill levels from 0, for those who cannot complete a single repetition and values greater than 20 for the well prepared individuals.	12-weeks
40m Fast-paced Walked Physical Performance	A fast-paced walking test that is timed over 4 x 10m (33 ft) for a total 40 m (132 ft) evaluating the ability to walk quickly over short distances. Time of one test trial is recorded and expressed as speed m/s by dividing distance (40m) by time (s).	12-weeks
Stair Climb Physical Performance	Evaluates the time (in seconds) it takes to ascend and descend a flight of stairs. Timing begins on the signal to start and terminates when the participant returns with both feet to the ground level and the total time to ascend and descend steps for 1 test trial is recorded to nearest 100th of a second.	12-weeks
Time up & Go Physical Performance	Evaluates the time (seconds) taken to rise from a chair, walk 3 m (9 ft 10 inches), turn, walk back to the chair, then sit down. Timing starts on the signal to start and terminates once the participant sits back down fully with their back resting on the back of the chair. Two trials are performed and the faster of the 2 trials is recorded to nearest 10th of a second.	12-weeks
Quality of Life evaluation	Evaluation of Quality of life through SF-36 (RAND version), which is a set of generic, coherent, and easily administered quality-of-life measures. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability and the higher the score the less disability.	12-weeks
Clinical Global Impression of Change (CGIC)	Physician assessment of joint swelling and range of motion (ROM) for knee extension/flexion, indicating the perceived change over the treatment period. The clinician is requested to choose one of seven categories. Scores range from very much improved to very much worse.	12-weeks
Assessment of use of rescue medicine	Evaluation of associated treatments needed to manage joint complains	12-weeks
