Name of the Condition

• Commonly known as Clutton's Joints. It is medically associated with syphilitic osteochondritis in congenital syphilis.

Summary

• Clutton's Joints is characterized by painless swelling of the knee joints, primarily in children with congenital syphilis. It's a manifestation of late congenital syphilis that can occur around 8-15 years of age.

Causes

• Clutton's Joints is caused by congenital syphilis, which is passed from a mother to her child during pregnancy. The condition itself results from inflammation due to the treponemal infection.

Risk Factors

• The primary risk factor is maternal syphilis during pregnancy, with untreated syphilis significantly increasing the likelihood of congenital syphilis in the newborn.

Symptoms

• Painless swelling in one or both knees, although other joints may occasionally be involved.
• No significant redness, warmth, or limitation of motion unless there is a secondary infection.

Diagnosis

• Diagnosis is typically based on clinical examination, patient history, and serological tests for syphilis (e.g., VDRL, FTA-ABS).
• Imaging like X-rays may show characteristic signs of syphilitic osteochondritis.

Treatment Options

• Antibiotics, primarily penicillin, to treat congenital syphilis.
• Management of symptoms with anti-inflammatory medications if needed.
• Regular monitoring and follow-ups to assess response to treatment.

Prognosis and Follow-Up

• With appropriate antibiotic treatment, the prognosis is generally good, and symptoms can resolve without lasting damage.
• Routine follow-up examinations are essential to ensure that syphilis is effectively treated and to monitor for any late manifestations.

Complications

• If untreated, Clutton's Joints may lead to joint deformities or more serious complications related to congenital syphilis, including neurological issues.

Lifestyle & Prevention

• Preventing maternal syphilis is crucial, which involves regular prenatal screenings and treatment during pregnancy.
• Safe sex practices and regular medical check-ups can help prevent syphilis transmission.

When to Seek Professional Help

• Seek medical advice if a child presents with unexplained knee joint swelling or if there's a known history of maternal syphilis.

Tips for Medical Coders

• Ensure accurate documentation of congenital syphilis and its manifestations.
• Be cautious not to confuse Clutton's Joints with other types of arthritides, as coding depends on the specific underlying cause.
