Goh GS, Zeng GJ, Tay DK, et al. - In this study, complication, mortality and revision rates, as well as patient-reported outcomes, and satisfaction were compared between patients with Parkinson’s disease (PD) and controls following total knee arthroplasty (TKA). Researchers distinguished individuals with PD who had undergone primary unilateral TKA and matched them 1:1 with a control group applying propensity scores adjusting for age, gender, body mass index, Charlson Comorbidity Index, baseline range of motion, Knee Society Knee Score, Knee Society Function Score, Oxford Knee Score, and 36-item Short-Form Health Survey Mental and Physical Component Summary. At 6 months and 2 years, functional outcomes, and patient satisfaction were measured. A total of 114 individuals were included in the study. In the PD group, the overall complication rate was 26.3% while in the control group it was 10.5%. Patients with PD did experience significant functional gains vs their preoperative status and reported high satisfaction, however these patients had relatively poorer knee function and quality of life.
