knee X-ray (musculoskeletal imaging in primary care)

Last reviewed 01/2018

Knee Xray

  • chronic knee pain warrants x-ray examination at any age

  • in the >50 age group x-ray examination must be performed before requesting an MRI as the former can highlight OA, which is often the major contributor to symptoms despite concurrent meniscal or ligamentous abnormality

  • anterior knee pain with suspected injury to the extensor mechanism (quadriceps and patellar tendons) or lump necessitates ultrasound examination first

Notes:

General Indications for x-ray examination

  • Bony tenderness
  • Inability to weight-bear
  • Acute joint pain
  • Gross joint deformity
  • Acute spinal pain in elderly (to rule out osteoporotic wedge fracture)
