[Clinic and pathology of the knee menisci injury with sclerosis denaturalization].
OBJECTIVE
To summarize the characteristics of clinic and pathology of the knee menisci injury with sclerosis denaturalization and to discuss the mechanism of the sclerosis and its clinic significance.


METHODS
We retrospectively analyzed the diagnosis and treatment and healing of the knee menisci with the sclerosis denatured injury from 1989 to 2003. The changes of the partial meniscus with sclerosis denaturalization were observed in tissue section.


RESULTS
Menisci with sclerosis denaturalization occupied 24.1%, and 77.6% of them subordinated to simple sclerosis denaturalization without tear. Their characteristics were that the manifestations were not except typical knee pain, tenderness at joint line,integrity shape with dull or less lubricity and tiny grand on the super face of menisci under the arthroscopy,and trembles could be touched by a probe. Pathology showed the formation of local sclerosis with the histological changes of fibro-hyperplasia, hyaline degeneration and mucous degeneration in the menisci. No operation obtained curative effects. Symptoms can be eliminated by the excision of the menisci with sclerosis denaturalization.


CONCLUSIONS
The clinic of simple meniscus injury with sclerosis denaturalization are non-typical and arthroscopic check-up is valuable for the diagnosis. The menisci can be removed from the patients suffered from heavy symptoms for a long time.
