Evaluation and Management of Pediatric Knee Pain

Pain Assessment

The American College of Rheumatology recommends monitoring pain intensity using validated tools like the Visual Analog Scale (VAS), which provides a score from 0-100 or 0-10, with scores of 10-30 indicating mild pain, 40-60 moderate pain, and 70-100 severe pain 2, 3
Assess the multidimensional nature of pain including sensory, affective, and evaluative components, as recommended by the American College of Rheumatology 2, 4

The American Academy of Pediatrics recommends looking for focal tenderness, effusion, and weight-bearing ability, which are key criteria for determining the need for imaging 1
Monitor for gross deformity, palpable mass, or signs of trauma that warrant immediate radiographic evaluation, as recommended by the American Academy of Pediatrics 1

The American College of Radiology recommends following radiographic findings, particularly when Ottawa rule criteria are present (focal tenderness, inability to bear weight) 1
Consider advanced imaging results when symptoms persist despite normal initial radiographs, as MRI can detect bone marrow lesions, stress fractures, and soft tissue pathology not visible on plain films 1

The American College of Radiology recommends monitoring for signs of infection including fever, worsening pain, and systemic symptoms 5
Watch for persistent pain despite appropriate treatment, which may indicate more serious underlying pathology, as recommended by the American College of Radiology 5
Be alert to referred pain patterns, as hip pathology can present as knee pain in the pediatric population, according to the American College of Radiology 5

The American Academy of Pediatrics recommends assessing pain at the first visit and at each subsequent visit at least 7 days apart using developmentally appropriate tools 2, 4
For patients with normal initial evaluation but persistent symptoms, conduct follow-up assessments as approximately 10% of fractures may only be visible on follow-up imaging, as recommended by the American College of Radiology 5
