Tiibercular Synovitis of Knee-joint. 445 



7. 45. Invasion of Articular Surfaces from Tubercular 



Synovitis. — Articular end of a right femur. 



The cartilaginous surface is bare and rough, except at one 

 place in front of the inner condyle. Some new periosteal bone 

 has formed above the articular surfaces, and there has been a 

 small erosion at the attachment of the popliteus muscle.

7. 46. Invasion of Articular Surfaces from Tubercular 



Synovitis. — Lower third of a left femur. 



There is roughness from rarefaction on the greater part of 

 the articular surface. New periosteal bone has been formed 

 above the articular end. F. P. C. 766. 



7. 47. Invasion of Articular Surfaces from Tubercular 



Synovitis. — Lower end of a left femur. 



The articular surface is almost entirely rough from rare- 

 faction and erosion. New periosteal bone has been formed in 

 the neighbourhood. F. P. C. 767. 



7. 48. Invasion of Articular Surfaces from Tubercular 



Synovitis. — Articular ends of a left femur and tibia. 



The articular surfaces of both bones are everywhere rough 

 from rarefaction, and, at many places, are eroded. Very little 

 new periosteal bone has been formed in the neighbourhood.

7. 49. Invasion of Articular Surfaces from Tubercular 



Synovitis. — Upper third of a left tibia. 



The articular surface, especially of the inner tuberosity, is
