Tremor Other Hyperkinet Mov (N Y). 2013 Jul 11;3:tre-03-153-3642-4. doi: 10.7916/D8MW2FVX. Print 2013.


Background: A 37-year-old female with a hyperkinetic movement disorder due to chorea-acanthocytosis developed severe painful degenerative arthritis of her left knee as a consequence of repetitive involuntary flexion and extension dystonic and ballistic movements.

Case report: Despite profound limitation in her mobility a total knee replacement was successfully undertaken.

Discussion: The case emphasizes that patients with progressive neurodegenerative disorders may derive relief or resolution of pain by joint replacement even if mobility does not improve following surgery. A multidisciplinary approach to care is essential.

Keywords: Neuroacanthocytosis; joint replacement; osteoarthritis.
