Why is it important to keep the knots in Buck's traction away from the pulleys?

Keeping the knots in Buck's traction away from the pulleys is crucial for avoiding interference with the pulling mechanism. When knots are positioned near or on the pulleys, they can obstruct the smooth movement of the traction system. This obstruction could hinder the effectiveness of the traction, as the weights may become stuck or unable to provide consistent pulling force. Proper alignment and functioning of the pulleys are essential for maintaining the appropriate tension needed to relieve pressure on the affected area and promote healing. Therefore, positioning the knots correctly is vital for ensuring that the traction works effectively and efficiently.
