Quantitative analysis of nerve changes in the lateral retinaculum in @entity1 with isolated symptomatic XXXX . A preliminary study.

@entity1 @entity3325 @entity16 @entity158 @entity4518
@entity16 in 16 lateral retinacula excised at the time of Insall proximal realignments or isolated lateral retinacular releases performed in @entity1 with symptomatic @entity4518 was evaluated by means of conventional histology and immunohistochemical and morphometric analyses. A relationship between clinical and histologic findings was found. An increase in the proportion of innervated tissue was correlated with @entity4518 . We found a significant relationship between total neural area and @entity158 . The group with moderate @entity158 had the highest number of nerves and the highest neural area. In reference to total neural area and @entity158 , there was a significant difference only between the @entity1 with moderate @entity158 and those with light @entity158 , but not between @entity1 with severe @entity158 and those with moderate @entity158 . The group with severe @entity158 also showed a high neural area, although with a lower number of nerves. The severe- @entity158 group had the largest nerves (24% of nerve fibers surpassing 25 microns diameter) in a zonal disposition, in which there were groups of nerve fibers in some fields and no nerve fibers in others. The group with moderate @entity158 had an increase in medium and small nerve fibers (mean diameter, 18 microns), predominantly of tiny perivascular fibers. Moreover, we believe that instability in @entity1 with @entity4518 can be explained in part because of @entity3325 due to @entity16 .
