Abstract
Objectives: The present research aimed to evaluate the relationship of supra patella effusion with pain and disability in patients with knee osteoarthritis by Ultrasonography (US).
Methods: In a cross-sectional study, 60 patients with knee OA (Mean±SD score of body mass index: 29.81±5.64 kg/m2 and age: 50.48±7.57 years) were selected by nonprobability sampling method. Supra patella effusion was evaluated using an US. All study subjects completed the Visual Analogue Scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) for pain and disability outcomes, respectively. To evaluate the relationship between effusion, disability, and pain, the Pearson’s correlation coefficient was employed.
Results: There was a poor but significant relationship between the area of effusion (r=0.27, P=0.03), the thickness of effusion (r=0.32, P=0.01), with pain. No correlation was found between the trace of effusion (r=-0.08, P=0.5) and pain. The area of effusion (r=0.1, P=0.17), the thickness of effusion (r=0.08, P=0.51), and the trace of effusion (r=0.0, P=0.9) were not correlated with disability.
Discussion: The effusion of supra patella was slightly correlated with pain. In contrast, the effusion of supra patella demonstrated no correlation with disability.

Abstract
Objectives: To compare the efficacy of balance exercises in the aquatic and Non-aquatic environments compared with control in patients with grade 2 or 3 knee Osteoarthritis (OA).
Methods: For this single-blind, randomized control trial study, 43 women with mild to moderate knee OA were recruited through a simple non-probability sampling method. They were randomly assigned to the aquatic balance exercise group (n=15), Non-aquatic balance exercise group (n=15), and a control group (n=13). The intervention programs comprised aquatic and Non-aquatic balance training. Fall risk, the primary outcome, was measured by the Biodex balance system before and after the intervention. One-way ANOVA and paired sample t-test were used for analyzing data.
Results: After 4 weeks training, the Mean±SD fall risk score significantly decreased from 3.49±1.14 to 2.59±1.22 (P<0.001) in the aquatic balance training group, from 3.21±0.62 to 2.19±0.62 (P<0.001) in the Non-aquatic balance training group, and from 3.77±1.13 to 3.17±1.22 (P<0.001) in the control group. Regarding between-group comparisons, we found significant differences between the Non-aquatic balance training group and the control group (P=0.03).
Discussion: Despite the environment, the balance exercise program significantly improved fall risk scores among patients with grade 2 or 3 knee osteoarthritis.
