Arthritis: Septic Arthritis.

Area of Science:

• Infectious Diseases
• Rheumatology
• Orthopedic Surgery

Background:

• Septic arthritis involves acute inflammation of a single joint due to infection, often bacterial.
• It presents a significant risk of morbidity and mortality, necessitating timely diagnosis and intervention.
• Risk factors include advanced age, smoking, comorbidities like diabetes and rheumatoid arthritis, and joint-related procedures.

Purpose of the Study:

• To highlight the critical importance of early suspicion and diagnosis of septic arthritis.
• To outline the management strategies, emphasizing the role of both medical and surgical treatments.
• To present the functional outcomes and mortality rates associated with septic arthritis.

Main Methods:

• Review of clinical presentation, risk factors, and diagnostic challenges.
• Analysis of management approaches, including medical and surgical interventions.
• Evaluation of patient outcomes, functional sequelae, and mortality data.

Main Results:

• Clinical presentation can mimic other joint conditions, complicating diagnosis.
• Poor functional outcomes (amputation, arthrodesis, etc.) affect 24-33% of patients.
• Mortality rates for knee septic arthritis vary significantly with age, reaching 22-69% in those over 79.

Conclusions:

• A high index of suspicion is essential for physicians managing septic arthritis due to its severe potential consequences.
• Management requires a tailored approach combining medical and surgical treatments.
• While medical treatment is effective, 30% of patients may ultimately need surgery.
