WOMAC (Western Ontario and McMasters Universities Osteoarthritis) was used for the assessment of the primary index and VAS (visual analogue scale) was for the secondary index.

In each group, 72 patients finished the trial and the data of the lost cases were included in the final data analysis.

  In the 4th week of trial, WOMAC score was (25. 8+/-22.0) in group A difference (P<0. 001). VAS scorewas (31. 8+/-24. and was (43.8+/-22.2) in group B, indicating the significant 6) in group A and was (56. 6 +/-25. 8) in group B, indicating very significant difference (P<0. 001).
