外傷性膝関節血腫に対する関節鏡検査の意義

抄録

Sixteen patients of traumatic hemoarthrosis of the knee joint were examined through arthroscopy, of which findings were compared with those of arthrography and radiography.
Meniscus tear was found in four cases on arthrogram, but arthroscopically recognized in only one of them. Arthroscopic examination revealed meniscus tear findings in other two of normal arthrograms concerning meniscus configuration.
Rupture of the medial collateral ligament in both the superficial and the deep layer was seen arthroscopically in six cases, while it could be recognized in five of them on the arthrogram.
On rupture of the cruciate ligament, five cases of complete rupture were proved arthroscopically and stress radiologically and three cases of incomplete rupture were proved only by arthroscopy.
Arthroscopic examination is greatly valuable in locating tearing area and determining the degree in the deep layer of the medial collateral ligament and anterior cruciate ligament, and is also very helpful for accurate diagnosis of meniscus tear.
