Hydroxyapatite deposition disease (HADD) of the knee

Case contributed by Dr Magdalena Chmiel-Nowak

Presentation

Sudden knee pain at the medial side. No trauma.

Patient Data

Age: 65 years
Gender: Female

Two calcific deposits are visible at the medial side of the knee, adjacent to MCL, in the location of POL and femoral attachment of MPFL, with some adjacent soft tissue edema.

MCL and the medial meniscus are unremarkable.

Case Discussion

HADD is typically found in the rotator cuff tendons but can occur in other joints as well. Acute onset of pain without trauma and characteristic appearance of periarticular calcific deposits, often with adjacent soft tissue edema usually point to this diagnosis.
