title: Intra-articular calcification in primary hyperparathyroidism.
abstract: We report a case of intra-articular calcification involving the knee joint secondary to primary hyperparathyroidism. This caused significant disability to the patient and following excision of the calcified mass the patients knee function returned to normal. This feature of hyperparathyroidism has not been previously reported.
