■are seen on the otlier half (below). The fatty condition of the 

 epiphyseal end of the shaft of the femur is very marked, and 

 the same may be seen on the tibia, but to a less extent. As in 

 the previous specimens, the condition of the epiphyses seems 

 healthy, while that of the adjacent ends of the shaft is fatty 

 and of a dark brown colour. G. C. 3182.

— Parts of a knee-joint removed by excision — in spirit, 

 showing slight outward dislocation of the tibia, with extensive 

 •destruction of the cartilaginous surfaces. 



Four years before admission to the Royal Infirmary, Edinburgh, 

 the patient, a lad aged 20, in jumping into a cart, had struck his knee 

 -on the tram. Displacement occurred at once, and remained in spite of 

 repeated attempts to restore it. 



Before operation the joint was swollen, slightly flexed, tender to the 

 touch, and painful when moved. The tibia was displaced outwards and 

 sliglitly rotated backwards. 



At the operation the articular surfaces were found to have adhesions 

 in process of formation. These had to be broken down to allow of the 

 excision. In this case tubercular synovitis distinctly followed the 

 injury. 



The articular cartilages of the joint have been entirely 

 replaced by irregular granulations, now blanched and shrivelled 

 by the spirit. Cx. C. 2890.

— Papier-mache cast of knee before operation, from which the 

 foregoing specimen was taken, to show the swelling of the joint 

 and the lateral displacement of the tibia. G. C. 2891.
