Arthroscopy in acute knee injuries.

O Simonsen, J Jensen, J Lauritzen

    Acta Orthopaedica Scandinavica
    |April 1, 1986
    PubMed
    Summary
    This summary is machine-generated.

    Arthroscopy significantly improved knee injury diagnosis, altering treatment plans in 31% of cases. This procedure is crucial for accurate anterior cruciate ligament tear identification, preventing missed diagnoses.

    Area of Science:

    • Orthopedic Surgery
    • Sports Medicine
    • Diagnostic Imaging

    Background:

    • Acute knee hemarthrosis and instability present diagnostic challenges.
    • Clinical examination alone may lead to inaccurate preoperative diagnoses.
    • Anterior cruciate ligament (ACL) injuries are common and require precise diagnosis.

    Purpose of the Study:

    • To evaluate the diagnostic value of arthroscopy in patients with acute knee hemarthrosis and/or instability.
    • To compare treatment plans based on clinical examination versus post-arthroscopy findings.
    • To assess the accuracy of stability testing under anesthesia for knee ligament injuries.

    Main Methods:

    • Retrospective analysis of 148 patients undergoing knee arthroscopy for acute hemarthrosis and/or instability.

  • Comparison of treatment planned after clinical examination with treatment administered after arthroscopic evaluation.
  • Detailed review of ligamentous injury types, including combined injuries and complete ruptures.

    • Main Results:

    • Arthroscopy altered planned treatment in 31% of cases.
    • Clinical examination alone would have resulted in serious diagnostic errors for 15% of patients.
    • Stability testing under anesthesia showed significant inaccuracy for ACL injuries (13% false positive, 30% false negative).
    • Twenty percent of complete ACL ruptures were at risk of being overlooked without arthroscopy.

    Conclusions:

    • Arthroscopy is a valuable diagnostic tool for acute knee hemarthrosis and instability.
    • It significantly improves diagnostic accuracy, particularly for anterior cruciate ligament tears.
    • Arthroscopic findings frequently lead to modifications in surgical planning, optimizing patient management.
