Gomez: To off-load the painful knee, Blau was fitted with a custom-designed brace that would realign his knee. It was part of a study in the Motion Analysis Lab at Hospital for Special Surgery. Special motion capture cameras analyzed his gait from all angles. They showed that the brace did slightly realign his knee.
A hydrocele is a painless buildup of watery fluid around one or both testicles that causes the scrotum or groin area to swell.r they can be caused by inflammation or infection of the epididymis or testicles. In rare cases, hydroceles may occur with cancer of the testicle or the left kidney. This type of hydrocele can occur at any age but is most common in men older than 40.
1 Hydroceles are painless, soft swellings and may be either present at birth (congenital) or develop later. 2  A very large majority of hydroceles present at birth resolve spontaneously by one year of age.  Hydroceles that are not congenital or those still present after one year of age generally warrant surgical correction.
