Lateral collateral ligament calcification
Citation, DOI & article data
Lateral collateral ligament calcification is rare that can cause acute knee pain.
Most patients with lateral collateral calcification are asymptomatic while a small proportion will have lateral knee pain.
Calcification is adjacent to the lateral femoral condyle, often linear or curvilinear in shape and paralleling the femoral cortex.
It appears as a low signal lesion in the lateral collateral ligament in comparison with the high attenuation area on the plain radiograph and may be associated with surrounding soft tissue edematous changes 1.
Treatment and prognosis
The management is usually conservative.
Post-traumatic calcification changes and crystal-induced arthropathies (calcium pyrophosphate deposition and gout) are in differential diagnosis 2.
