Total hip arthroplasty in Parkinson's disease - A systematic review of the current evidence

This systematic review assessed the efficacy, survivorship, and complications of Total Hip Replacement (THR) in Parkinson's Disease (PD). Databases were searched according to the Preferred Reporting Items for Systematic Reviews. PD patients had higher wound infections, dislocations, peri-prosthetic fractures, and revision surgery compared to their non-PD counterparts. They also had inferior functional outcomes, and longer and expensive hospital admissions. Dual-mobility (DM) implants had the lowest survival rate. THR in PD patients is associated with significant surgical complications and peri-operative challenges. Despite the use of DM implants to minimize instability, there is insufficient evidence on its effectiveness and long-term survivorship.
