Reactive Arthritis is an autoimmune inflammatory disorder in which the body's immune system reacts abnormally following an infection elsewhere in the body. The infection typically occurs in the:

• Gastrointestinal tract
• Genitourinary tract

Although the triggering infection may have resolved, the immune system continues to cause inflammation in joints and other tissues.

Historically, the condition was known as Reiter’s Syndrome, characterized by the classic triad of:

• Arthritis
• Urethritis
• Conjunctivitis

However, the term Reactive Arthritis is now preferred in medical practice.

Reactive Arthritis belongs to a group of conditions called seronegative spondyloarthropathies, which are inflammatory disorders affecting joints and sites where tendons attach to bones (entheses).

The condition most commonly affects young adults between 20 and 40 years of age and is more common in men.

Symptoms often begin 1–4 weeks after an infection and may last for several months. While many individuals recover completely, some may develop chronic or recurrent symptoms.

At Magnum Physiotherapy, our rehabilitation programs focus on controlling pain, preserving joint mobility, strengthening muscles, and improving overall function.

Causes & Risk Factors

Reactive Arthritis usually develops after bacterial infections.

Gastrointestinal Infections

• Salmonella
• Shigella

Genitourinary Infections

• Chlamydia trachomatis

Genetic Factors

• Presence of HLA-B27 gene

Individuals with HLA-B27 are at increased risk of developing more severe disease.

Risk Factors

• Age 20–40 years
• Male gender
• Previous infection
• Family history of spondyloarthropathy

Common Symptoms

• Morning stiffness
• Lower back pain
• Heel pain
• Reduced mobility

Joints commonly affected include:

• Knees
• Ankles
• Feet
• Sacroiliac joints

Enthesitis Symptoms

Inflammation where tendons attach to bone:

• Achilles tendon pain
• Plantar fascia pain
• Heel tenderness

Urinary Symptoms

• Painful urination
• Increased urinary frequency
• Urethral discharge

Eye Symptoms

• Conjunctivitis

• Nail changes
• Keratoderma blennorrhagica

Conditions Associated with Reactive Arthritis

• Sacroiliitis
• Ankylosing Spondylitis
• Psoriatic Arthritis
• Enthesitis
• Achilles Tendinopathy
• Plantar Fasciitis
• Uveitis

Diagnosis

There is no single test for Reactive Arthritis. Diagnosis is based on clinical findings and medical history.

Investigations may include:

• Detailed medical history
• Physical examination
• Blood tests
• Inflammatory markers (ESR, CRP)
• HLA-B27 testing
• Urine tests
• Stool cultures
• Joint fluid analysis
• X-rays
• MRI scans when indicated

At Magnum Physiotherapy, we assess:

• Joint mobility
• Muscle strength
• Gait patterns
• Functional limitations
• Posture and balance

Treatment at Magnum Physiotherapy

Treatment focuses on reducing inflammation, maintaining mobility, and preventing long-term disability.

Medical Management

Medical treatment may include:

• Antibiotics (when infection is present)
• Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)
• Corticosteroids
• Disease-Modifying Anti-Rheumatic Drugs (DMARDs) in chronic cases

Recovery & Prognosis

Many individuals recover within 6–12 months, although some develop chronic or recurrent symptoms.

Factors affecting prognosis include:

• Presence of HLA-B27
• Severity of inflammation
• Early treatment
• Adherence to rehabilitation

Regular follow-up and early intervention improve long-term outcomes.

When Should You Seek Medical Attention?
