In theantero-posterior varieties, which are generally complete, there isgreat shortening and deformity of the Hmb ; the head of the tibiain the forward dislocation projects anteriorly; whilst in the back-ward it can be felt in the ham. In the former there is generallyconsiderable sweUing and congestion, and often pain in the limb BURSA I Fig. 187. ;TRANSVERSE CUT lOBLIQUE Authors method < tiiii; llie tubercle of the tibia for the purpose of shortening anelongated patellar ligament. below the knee, from pressure of the condyles of the femur onthe popliteal vessels and nerves. Trea(me7it.—Reduction, as arule, is easily accomplished by extension, combined with manipnlation and pressure in the direction indicated by the variety ofthe dislocation. The limb should then be placed on a back-splint, and an ice-bag apphed to the knee, passive movementsbeing begun at the end of two or three weeks, and a knee-capsubsequently worn for twelve months at the least. Compounddislocations usually, though not invariably, call for amputation. Dislocation of one of the seniiliinar cartilages of the knee,usually the internal, may occur from a sudden twist or wrench ofthe joint during semi-flexion. The accident is attended withsudden and severe pain, a locking of the joint usually in a bentposition, and the presence of a hollow, sometim
