Tulercular Synovitis of Knee-joint. 441 



on 26th October 1891, complaining of a jumping pain in her left knee, 

 when going to sleep. She had no i^ain when sitting with her leg hanging, 

 but when lying down had pain. She first felt a pain in her knee 

 fourteen years ago, without any apparent cause. It has gradually 

 increased, especially during the last two years. The knee has been 

 blistered with but little effect. The knee is now bent at an angle of 

 130°, and the leg is everted. There is a wasting of muscles above and 

 below the joint, and the circumference of the joint is two inches greater 

 than on the sound side. The knee was excised on 30th October. The 

 wound healed slowly, leaving a sinus, which was gouged out on 5th 

 January 1892. 



The necrosed piece was denser than the rest, and on section, 

 when fresh, showed the following points, viz., near the articular 

 surface a layer which Avas of an opaque yellow colour ; next to 

 that one of a more clear, bluish, translucent colour ; then the 

 line of demarcation, with soft granulation tissue, and beyond 

 that the cancellous bone. 



The lower piece of the specimen has been macerated to 

 illustrate the rarefied condition of the bone. The upper part 

 of the articular surface is covered by shrivelled granulations 

 and has been irregularly eroded. G. C. 3341.

 Patch on the Inner Condyle. — Macerated section of the 

 portion of the inner condyle which contained the necrosed 

 portion in the previous case. The condensed character of the 

 necrosed piece, the line of demarcation round it, and the more 

 open character of the cancellous tissue beyond, can be recog- 

 nised. G. C. 3342.
