In 1923, I 1 reported a case of loose body under the external semilunar cartilage of the knee, cited here as case 1. Since then I have had one more similar experience. In the literature at my disposal I cannot find any mention of this condition and a knowledge of it seems important.

Able surgeons have been known to fail in locating and removing a loose body. To open a knee joint is always an operation of magnitude and not to succeed in accomplishing the desired object is a surgical disaster. The condition here cited may, or may not, be excessively rare.
