Background.
Although active ankle movement plays a predominant role in mechanical thromboprophylaxis following total hip arthroplasty (THA), the most effective frequency of movement remains unclear.
Materials and Methods.
In 29 consecutive patients undergoing THA, the velocity of blood flow in the profunda femoris was measured after various frequencies of ankle movement two days after THA using a pulse wave Doppler ultrasound system.
To test the interobserver reliabilities for the velocity measured with Doppler ultrasound system, the intraclass correlation coefficient was calculated based on the measurement in 10 limbs of healthy volunteers.
Results.
At 0, 1, and 2 minutes after ankle movement, the velocity after movement at 60 contractions per minute was significantly faster than that after movement at 40 or 80 contractions per minute (p=0.0007, repeated-measures analysis of variance).
The intraclass correlation coefficient score in two investigators was 0.849 (95% confidence interval, 0.428 to 0.962).
Conclusions.
Active ankle movement at 60 contractions per minute is recommended in patients receiving THA to obtain optimal venous blood flow.
