Comparing Intra-articular Betamethasone (Diprospan) and Triamcinolone Acetonide Injection in Knee Osteoarthritis

• The 100-mm VAS pain score is a self-reported instrument assessing Pain Score at 1 day, 2 days, 3 days, 1 week, 3 weeks, 1 month, 2 months, 3 months, 4 months, 5 months, 6 months after the day of intra-articular injection
• Participants will assess the VAS pain score at rest and on-movement
• VAS Pain at rest is evaluated when the participant's wakeup in the morning
• VAS Pain on-movement is evaluated when the participant's walking for 10 meters and then resting for 5 minutes
• Possible scores range from 0 (no pain) to 100 (worst imaginable pain)
• Higher scores mean a worse pain

• The Modified WOMAC score is a validated, self-reported instrument consisting of 24 items divided into 3 subscales (Pain, Stiffness, Physical function).
• The test questions are scored on a scale of 0-4, which corresponds to None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4).
• Possible scores range from 0-20 for pain, 0-8 for Stiffness, 0-68 for Physical function.
• a sum of the scores for all three subscales gives a total WOMAC score (0-96)
• Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations.

• The UCLA is a 10-point scale measurement that evaluates patients' daily activity levels.
• The 10-point scale is leveled from 1 to 10 (1= worst, 10 = best).
• Level 1 is wholly inactive and dependent on others, while level 6 is unlimited housework and shopping and level 10 is regular participation in impact sports, such as jogging or tennis.

• Flexion and extension angle of the knee is measured by a long-arm goniometer

• The Time up-and-go test (TUGT) measures the time (seconds) that the patient takes to rise from a chair and walk for 3 meters. Then, he or she turns around and comes back to the seat at the initial position.
• They were permitted to use walking aids if they wished.
• TUGT was a reliable and valid test for quantifying functional mobility.

• Participants were instructed to walk for 2 minutes at their normal pace up and down a designated corridor, turning around at each end of the corridor without stopping
• They were permitted to use walking aids if they wished.
• The results were recorded as the total distance walked in meters.

Injection site reaction, Erythema, Swelling, Injection-site pain, Pruritus, cellulitis were observed after intra-articular injection.

• Post-injection protocol, Participants can use Paracetamol 500 mg 2 tabs every 4 hours for knee pain if it did not relieve the pain they can take Tramadol 50 mg 1 cap every 6 hours.
• The total use of Paracetamol and Tramadol was recorded. (tablet)
