Is Parkinson's Disease Associated with Increased Mortality, Poorer Outcomes Scores, and Revision Risk After THA? Findings from the Swedish Hip Arthroplasty Register.

Background: Neurological conditions such as Parkinson's disease are commonly accepted as a risk factor for an increased likelihood of undergoing revision surgery or death after THA. However, the available evidence for an association between Parkinson's disease and serious complications or poorer patient-reported outcomes after THA is limited and contradictory.

Questions/purposes: (1) Do patients with a preoperative diagnosis of Parkinson's disease have an increased risk of death after elective THA compared with a matched control group of patients? (2) After matching for patient- and surgery-related factors, do revision rates differ between the patients with Parkinson's disease and the matched control group? (3) Are there any differences in patient-reported outcome measures for patients with Parkinson's disease compared with the matched control group?

Methods: Data were derived from a merged database with information from the Swedish Hip Arthroplasty Register and administrative health databases.
