T3	43.51 (±4.42)	45.13 (±5.03)	0.590
T4	43.38 (±4.49)	44.94 (±4.92)	0.757
T5	43.29 (±4.47)	45.03 (±4.94)	0.672
T6	43.16 (±4.44)	44.99 (±4.98)	0.670

T8	42.94 (±4.45)	44.69 (±5.36)	0.585

T1: before the arthrocentesis procedures; T2: seven days after the arthrocentesis procedures; T3: fifteen days after the arthrocentesis procedures; T4: one month after the arthrocentesis procedures; T5: three months after the arthrocentesis procedures; T6: six months after the arthrocentesis procedures; T7: nine months after the arthrocentesis procedures; T8: and one year after the arthrocentesis procedures. SD: standard deviation.
