History
The condition was initially described by Alexander Monro (primus) in 1738. In 1870, James Paget described the disease process for the first time, but it was not until 1887 that Franz König published a paper on the cause of loose bodies in the joint. In his paper, König concluded that:
- Trauma had to be very severe to break off parts of the joint surface.
- Less severe trauma might contuse the bone to cause an area of necrosis which might then separate.
- In some cases, the absence of notable trauma made it likely that there existed some spontaneous cause of separation.
König named the disease "osteochondritis dissecans", describing it as a subchondral inflammatory process of the knee, resulting in a loose fragment of cartilage from the femoral condyle. In 1922, Kappis described this process in the ankle joint. On review of all literature describing transchondral fractures of the talus, Berndt and Harty developed a classification system for staging of osteochondral lesions of the talus (OLTs). The term osteochondritis dissecans has persisted, and has since been broadened to describe a similar process occurring in many other joints, including the knee, hip, elbow, and metatarsophalangeal joints.

Famous quotes containing the word history:
“... that there is no other way,
That the history of creation proceeds according to
Stringent laws, and that things
Do get done in this way, but never the things
We set out to accomplish and wanted so desperately
To see come into being.”
—John Ashbery (b. 1927)
“Yet poetry, though the last and finest result, is a natural fruit. As naturally as the oak bears an acorn, and the vine a gourd, man bears a poem, either spoken or done. It is the chief and most memorable success, for history is but a prose narrative of poetic deeds.”
—Henry David Thoreau (1817–1862)
“False history gets made all day, any day,
the truth of the new is never on the news
False history gets written every day
...
the lesbian archaeologist watches herself
sifting her own life out from the shards she’s piecing,
asking the clay all questions but her own.”
—Adrienne Rich (b. 1929)
