One of the key signs to assess before and after splinting a knee fracture is the presence of a peripheral pulse. This assessment is crucial because it helps to determine the effectiveness of blood flow to the lower limb distal to the injury site. When a fracture occurs, particularly in the knee area, there can be damage to blood vessels, leading to compromised circulation. By checking for the presence of a pulse, healthcare providers can ensure that blood continues to circulate adequately beyond the injury, which is vital for tissue survival and healing.

Assessing the peripheral pulse before and after splinting is also important to monitor any changes that might indicate a worsening condition or vascular compromise as the injury is managed. If there is a loss of pulse, it could suggest that the splinting may be too tight or there may be additional complications developing.

While factors such as pain level, skin color, and movement ability are important components of a comprehensive assessment following trauma, they do not specifically provide the direct information about blood flow that the assessment of peripheral pulses does. Hence, the focus on assessing peripheral pulses specifically addresses the critical aspect of circulatory status in the context of a knee fracture.
