se “DISLOCATION OF THE KNEE-PAN. 
The knee-pan may be displaced either partially, or wholly, and in 
any direction laterally; this may also happen at the same time with 
~ a dislocation of the Knee-joint. It cannot, however, be completely 
luxated, without a rupture of the ligament that connects it with the 
shin bone, or the muscles of the thigh. : 
A dislocation of the knee-pan is

The shin bone of the leg, only, is concerned immediately in the 
joint of the knee; but as this bone cannot be dislocated without 
drawing the other after it, I shall mention both together. 
As great strength is required in the knee, the bones of which it is _ 
formed, are connected together by the strongest kind of articulation, 
viz. : the hinge-like joint ; and this is firmly tied togther by strong, 
‘ligaments. An unusual degree of violence is therefore requisite to 
force these bones out of joint, and this cannot be completely done, 
_ without rupturing the ligaments. 
‘The most partial luxation of this joint is readily distinguished by 
the violent pain it excites, and by the deformity and lameness it pro- 
duces. When the knee-pan is dislocated at the same time with the 
— bones, it will generally comé in place on the reduction of these 
Luxations of this joint should be replaced by fixing the thigh with — 
sufficient firmness, and extending the leg till the ends of the bones — 
are entirely clear of each other, when they are easily brought in 
_ place. Where the bones are completely displaced, considerable
