454 Diseases of Joints. 



The inner condyle is atrophied, and shows only a small 

 patch of cartilaginous surface near the back. The outer 

 condyle and the greater part of the trochlear surface are wanting,, 

 and the exposed cancellous bone is irregular. This also has 

 probably been a chronic case with anchylosis.

subsiding". — Lower end of a left femur— macerated, illus- 

 trating the above. 



The front of the trochlear surface and of the outer 

 condyle has disappeared, exposing the interior. The scanty- 

 remains of the outer condyle has circular tubercular erosions 

 upon it, and the back of the inner condyle is altered in shape 

 and porous on the surface. 



Apparently this has been an old-standing case in which 

 there has been anchylosis of the joint, with much distortion.

Lower end of a right femur — macerated, illustrating the above. 



The trochlear surface and the outer condyle, except a small 

 spur of it at the back, have disappeared, and the articular 

 surface of the inner condyle is scooped out and rarefied. The 

 surface left where the bone has disappeared is rarefied, and 

 shows numerous necrotic fragments in process of separation. 

 There is also a scale of necrotic bone in process of separation,, 

 on the outer side of the shaft above the gap. 



The great loss of substance on the outer condyle has 

 probably been from tuberculosis, but the necrotic appearances 

 noted have almost certainly been due to septic inflammation.
