|January 1, 1979
Summary
Double contrast arthrography accurately diagnoses knee injuries like meniscal and ligament tears, especially when clinical signs are unclear. This imaging technique achieved 81% pre-operative diagnostic accuracy in suspected internal derangements.
Area of Science:
- Radiology
- Orthopedics
- Medical Imaging
Background:
- Knee injuries often pose diagnostic challenges.
- Accurate diagnosis is crucial for effective treatment of internal knee derangements.
Purpose of the Study:
- To evaluate the diagnostic utility of double contrast arthrography for internal knee derangements.
- To assess the pre-operative diagnostic accuracy of this imaging method.
Main Methods:
- Double contrast arthrography was performed on 100 patients with suspected internal knee derangement.
- Radiological findings were analyzed, and diagnoses were confirmed surgically where possible.
Main Results:
- Abnormal radiological findings were identified in 31 cases.
- The pre-operative diagnostic accuracy was 81% in patients who underwent surgery (17 out of 21).
- The technique allowed detailed study of menisci and detection of ligamentous tears.
Conclusions:
- Double contrast arthrography is a valuable tool for diagnosing knee injuries, particularly when clinical signs are non-specific.
- Its diagnostic accuracy can be improved with experience and combined use with arthroscopy.
