Purpose
[edit | edit source]
A clinical decision rule used to indicate radiography of the knee.
Criteria
[edit | edit source]
Radiographs of the knee should performed if the mechanism of injury is a fall or blunt trauma and either one of the following:
1) Patient is younger than 12 or older than 50
2) Inability to walk four weight-bearing steps
These rules do not apply to individuals who present more than 6 days after injury, those with only superficial lacerations and abrasions, those with a previous history of knee injury or surgery on the affected knee, and those being reassessed for the same injury. [1]
Evidence[edit | edit source]
Diagnostic Accuracy[edit | edit source]
In a study by Seaberg et al., of 934 patients evaluated the Pittsburgh knee rules applied to 745 with a sensitivity of 0.99 and a specificity of 0.60. There was the potential to reduce radiography by 52% with one missed fracture. [2]
In a more recent study by Cheung et al., the Pittsburgh knee rules had a pooled sensitivity of 0.86 and a pooled specificity of 0.51. [3]
