Advantages, Disadvantages, Risks, and Limitations Associated With Using Stress Radiography

Advantages	Disadvantages	Risks	Limitations
The technique has a low cost.	Radiation is emitted to the patient and the examiner who performs the examination.	Radiation	Only 1 knee can have a ligament injury.
The technique is simple to perform.	The examiner must know how to perform the technique, paying attention to the correct degree of knee flexion, as well as the rotation of the limb.	Pain when performing examination	Digital radiography is recommended.
The technique requires simple items found in clinics and hospitals that perform radiography (e.g., thick, soft cushion and 2- to 3-step ladder).	Eventually, radiography should be repeated if the technique has not been applied correctly.		Lead cloaks and lead gloves must be available to protect the examiner.
	The cushion used can hinder image interpretation. In our study, the cushion decreased the radiotransparency but without affecting the interpretation of the examination.		In acute injuries, stress radiography may not be possible because of edema and pain in the affected knee.
