Abstract

The patella is rarely affected by Paget disease of bone. The authors report a 54-year-old lady with ipsilateral knee and hip pain, initially misdiagnosed as patella stress fracture and early degenerative hip arthritis, who was later found to have Paget disease of the patella with ipsilateral femoral head bone marrow edema.


Key Points


* Paget disease of patella may be overlooked in cases of persistent anterior knee pain.


* Persistent knee pain may affect the ipsilateral hip joint, and femoral head bone marrow edema can appear.
