Clinical Scorecard: Postoperative Outcomes and Risk Factors in Revision Total Knee Arthroplasty for Patients with Osteoarthritis Linked to Metabolic Syndrome: A Decade-Long Retrospective Study Utilizing a National Inpatient Database

At a Glance

Key Highlights

• Prevalence of MetS-OA among RTKA patients increased to 16.1% from 2011 to 2019.
• Factors associated with MetS-OA include advanced age, male sex, non-White racial background, and comorbid conditions.
• Patients with MetS-OA had longer hospital stays and higher hospitalization charges.
• Postoperative complications were more likely in patients with MetS-OA, including acute myocardial infarction and acute renal failure.
• In-hospital mortality rates did not significantly differ between MetS-OA and non-MetS-OA groups.

Guideline-Based Recommendations

Diagnosis

• Identify MetS-OA based on the presence of osteoarthritis, obesity, and at least two metabolic abnormalities.

Management

• Implement targeted preoperative optimization and standardized perioperative management strategies.

Monitoring & Follow-up

• Monitor for postoperative complications, particularly in patients with MetS-OA.

Risks

• Increased risk of postoperative complications and higher hospitalization charges in patients with MetS-OA.

Patient & Prescribing Data

Patients aged 18 years and older undergoing RTKA.

Higher median total hospitalization charges exceeding $1,445.50 for patients with MetS-OA.

Clinical Best Practices

• Assess and manage comorbid conditions preoperatively.
• Utilize a multidisciplinary approach for perioperative care.
• Educate patients on the risks associated with MetS-OA.
