Monoarthritis of hip joint

Last edited: 4/15/2026

Overview

Monoarthritis of the hip joint refers to inflammation or infection affecting a single hip joint, often presenting as pain, swelling, and limited range of motion. 1

Diagnosis

  • Clinical history and physical examination focusing on joint symptoms and systemic signs.
  • Radiographic imaging (X-ray) to assess for structural abnormalities, erosions, or joint space narrowing.
  • MRI or ultrasound for detailed soft tissue evaluation, particularly useful in differentiating between inflammatory and infectious causes.
  • Laboratory tests including inflammatory markers (ESR, CRP) and synovial fluid analysis if aspiration is performed. 1

    • Management

  • First-line treatments: Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain and inflammation management.
  • Adjunctive treatments: Corticosteroid injections into the hip joint for severe inflammatory conditions.
  • Antimicrobial therapy: If infection is suspected or confirmed via synovial fluid analysis, initiate targeted antibiotics based on culture and sensitivity results.
  • Physical therapy: To maintain joint mobility and strength, particularly important post-acute phase. 1

    • Special Populations

  • Postmenopausal women: Consider potential impact of decreased sexual activity and perineal hygiene on conditions like labial adhesions, which may indirectly affect hip joint disease management. 1

    • Key Recommendations

  • Perform synovial fluid analysis when monoarthritis of the hip is suspected to differentiate between inflammatory and infectious etiologies (Evidence: Moderate 1).
  • Initiate NSAID therapy for pain and inflammation control in patients with monoarthritis of the hip (Evidence: Moderate 1).
  • Consider corticosteroid joint injections for refractory inflammatory symptoms, balancing risks and benefits (Evidence: Expert opinion 1).
