Evaluation of Risk Factors for Periprosthetic Joint Infection Following Reverse Shoulder Arthroplasty: A Multivariate...

Area of Science:

• Orthopedic Surgery
• Infectious Disease
• Biostatistics

Background:

• Reverse shoulder arthroplasty (RSA) is increasingly used for various shoulder conditions.
• Periprosthetic joint infection (PJI) is a serious complication following arthroplasty.
• Identifying risk factors for PJI after RSA is crucial for patient outcomes.

Purpose of the Study:

• To identify risk factors associated with periprosthetic joint infection (PJI) after reverse shoulder arthroplasty (RSA).

Main Methods:

• Retrospective case-control study involving 302 patients who underwent RSA.
• Patients were divided into infected (PJI) and non-infected groups.
• Univariate and multivariate logistic regression analyses were used to determine independent risk factors.

Main Results:

• The incidence of PJI was 4.3% (13 out of 302 patients).
• Preoperative C-reactive protein (CRP) levels and a history of diabetes were significantly associated with PJI.
• Diabetes was identified as an independent risk factor for PJI (odds ratio = 4.85, p = 0.01).

Conclusions:

• Diabetes is a significant independent risk factor for periprosthetic joint infection following reverse shoulder arthroplasty.
• Preoperative CRP levels showed an association but were not an independent risk factor.
• Preoperative risk stratification should consider diabetes history in patients undergoing RSA.
