Summary
Psoriasis significantly increases the risk of hip prosthesis infection. Patients with psoriasis had a 21-fold higher odds of hip implant infection, highlighting a crucial link for orthopedic surgery.
Area of Science:
- Orthopedic Surgery
- Dermatology
- Infectious Diseases
Background:
- Hip and knee prosthesis infections are significant complications.
- Psoriasis as a risk factor for prosthesis infection remains understudied.
Purpose of the Study:
- To investigate the association between psoriasis and the risk of hip and knee prosthesis infection.
Main Methods:
- A case-control study was conducted.
- Included 85 patients with infected prostheses and 202 controls without infection.
- Psoriasis prevalence was compared between groups.
Main Results:
- Psoriasis was present in 17.6% of infected patients versus 1% of controls.
- Psoriasis showed a 21.4-fold increased odds of prosthesis infection.
- A significantly higher risk (39.7-fold) was observed for hip prosthesis infections in psoriasis patients.
Conclusions:
- Psoriasis is identified as a significant risk factor for hip prosthesis infections.
- No significant association was found for knee prosthesis infections.
- Preoperative screening for psoriasis may be warranted in patients undergoing hip replacement.
