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.
