Evaluating the Effectiveness of Mobithron Xtra in Patients With Primary Knee Osteoarthritis Over a 3-month Period

The WOMAC is a validated patient-reported outcome measure assessing pain, stiffness, and physical function in individuals with osteoarthritis. The total WOMAC score ranges from 0 to 96 points, with higher scores indicating worse pain, stiffness, and functional impairment (worse outcome) and lower scores indicating better clinical status (better outcome). Effectiveness will be assessed by comparing the change in WOMAC total score from baseline to the end of treatment at 3 months

The Visual Analog Scale (VAS) for Pain is a patient-reported measure of pain intensity. Participants rate their pain on a scale ranging from 0 to 10, where 0 represents no pain and 10 represents the worst imaginable pain. Higher scores indicate greater pain severity (worse outcome), while lower scores indicate less pain severity (better outcome). Effectiveness will be assessed by comparing the change in VAS pain scores from baseline to the end of treatment at 3 months.

This section evaluates the effectiveness, side effects, and convenience of the medication taken by the patients, and is evaluated on the likert scale from 1 to 7. A lower score indicates a worse outcome whereas a higher score indicates a better outcome.

The Patient Global Impression of Change (PGIC) is a patient-reported measure that assesses participants' perception of overall change in their condition since starting treatment. Participants rate their overall condition using a 7-point ordinal scale: 1. Very much improved, 2. Much improved, 3. Minimally improved, 4. No change, 5. Minimally worse, 6. Much worse, or 7. Very much worse. Higher levels of improvement indicate a better outcome, while worsening categories indicate a poorer outcome.

Knee range of motion (ROM) will be assessed using a goniometer and recorded in degrees (°). Measurements will be obtained at baseline and at each follow-up visit through Month 3. Effectiveness will be evaluated by assessing the change in ROM over time and identifying progressive trends in knee mobility improvement. Higher ROM values indicate greater joint mobility and a better outcome.

Number of participants experiencing treatment-emergent adverse events (TEAEs), serious adverse events (SAEs), and adverse drug reactions (ADRs). The events will be escalated to the research team and recorded in the standardised Adverse Drug Reaction form. All data collected will be monitored continuously throughout the study period.
