Objective:

imaging studies

ICD-10:

S83

Description:

Most patients with knee injury have soft tissue damage to ligaments, tendon or meniscus; while these may be serious, radiography does not significantly help in diagnosis and may be unnecessary. A decision rule can be used in adults to reduce the number of unnecessary radiographic examinations of the knee. This could lead to important health savings without jeopardizing patient care.
