    Arthroscopic examination of knee sprains with hemarthrosis identified bleeding sources in most patients. Cruciate ligament tears were common, but complete tears and fractures were less frequent, with limited impact on treatment plans.

    Area of Science:

    • Orthopedic Surgery
    • Sports Medicine
    • Knee Injuries

    Background:

    • Hemarthrosis in knee sprains often necessitates diagnostic evaluation.
    • Arthroscopy is a key tool for visualizing intra-articular pathology.
    • Identifying the source of bleeding is crucial for accurate diagnosis and management.

    Purpose of the Study:

    • To evaluate the utility of arthroscopic examination in patients with sprained knee injuries and hemarthrosis.
    • To determine the common intra-articular pathologies causing hemarthrosis in this patient group.
    • To assess the impact of arthroscopic findings on treatment decisions.

    Main Methods:

    • Prospective study of 90 consecutive patients with sprained knee injuries and hemarthrosis.
    • Exclusion criteria included signs of instability or fracture.

  • All patients underwent thorough arthroscopic examination to identify the source of bleeding and associated injuries.

    • Main Results:

    • The source of bleeding was identified in 85 out of 90 patients (94.4%).
    • Common findings included cruciate ligament tears (39 cases, 3 complete), osteochondral fractures (14 cases), and meniscal lesions (6 cases).
    • Bleeding also originated from synovium or meniscal attachments in remaining cases.

    Conclusions:

    • Arthroscopic examination is highly effective in identifying bleeding sources in knee sprains with hemarthrosis.
    • While ligament tears are frequent, significant fractures and complete tears are less common.
    • Arthroscopy rarely altered the treatment course in this specific patient cohort.
