Primary Outcome Measures:
  • The primary outcome measures is defined as the change from baseline to final assessment of the study knee in the 3 core continuous variables pain and physical function, assessing using the WOMAC subscales, and patient global assessment (PGA). [ Time Frame: the outcome is assessed at week 1 ] [ Designated as safety issue: Yes ]
  • The primary outcome measures is defined as the change from baseline to final assessment of the study knee in the 3 core continuous variables pain and physical function, assessing using the WOMAC subscales, and patient global assessment (PGA). [ Time Frame: the outcome is assessed at week 2 ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Active Comparator: P (Pircoxicam Group)
in this arm 100 patients with osteoarthritis of knee will receive piroxicam gel in blinded 60 grams tubes,they will be instructed to use 1 gram of piroxicam gel (with inserted dispensing device) three times in a day on the affected knee.
Drug: Piroxicam
In this interventional arm gel of piroxicam (manufactured by Iran najo co,Iran), repackaged in a 60 g anonymous tubes will be administered to the patients.
Other Name: Piroxicam topical gel
Experimental: O (olive oil group)
in this arm 100 patients with osteoarthritis of knee will receive virgin olive oil in blinded 60 grams tubes,they will be instructed to use 1 gram of olive oil (with inserted dispensing device) three times in a day on the affected knee.
Dietary Supplement: Olive Oil
virgin olive oil prepared directly from olive fruit from "olive gardens of north of iran, Gilan province" will packaged in a 60 g anonymous tubes.
Other Name: Topical virigin olive oil

Detailed Description:

application of herbal product has old history in therapy of human diseases. olive oil is one of the important diet in Iran which its efficacy in reducing of rheumatic pains was pointed out by Avicenna in 10th century. Nevertheless, its efficacy is not confirmed by scientific study.

in this double blinded study, 200 patients with diagnosed osteoarthritis of knee will be recruited that will randomly be assigned in piroxicam or olive oil group. the piroxicam gel or olive oil will be repackaged in anonymous tubes, which only recognizable via codes. the patients or visiting clinicians will be unaware of content of tubes. the final assessor will be blind to groups and interventions.

the efficacy of therapies will be evaluated by means of WOMAC and PGs standard questionnaires.
