Changes in the parameters of the Lequesne index and aspirated synovial fluid volumes before, during, and after LLLT.

	Before LLLT (time of 1^st LLLT)	2 weeks after 1^st LLLT (time of 2^nd LLLT)	2 weeks after 2^st LLLT (time of 3^rd LLLT)	1-month follow-up	3-month follow-up	6-month follow-up
Average aspirated SF volume in mL
Lequesne functional index

LLLT: low-level laser therapy; mL: milliliter. Statistical analysis of 3^rd LLLT (at this time, patients have completed 2 LLLT treatments), 1-month follow-up, and 3-month follow-up periods as compared with the time before LLLT or received only 1 LLLT and at 6 months follow-up (). Values are expressed as (SD).
