Therewas almost no swelling, and the limb was moderately flexed. By firmpressure the patella could be restored to position, but as soon as thehand was removed it returned to its original position. At the end oftwo months a good degree of motion existed at the knee-joint, whichwas in no way inflamed or Symptoms.—The limb is slightly bent, but immovable; the breadthof the knee is considerable increased; the inner condyle projects un-naturally, and the patella is distinctly felt upon the outer side.

DISLOCATIONS OF THE PATELLA OUTWARDS. 739 dislocation is partial, the outer margin of the patella forms an irregularsharp ridge in front of the external condyle. If it is complete, theinner margin presents itself in front of the external condyle, and theouter margin looks backwards. Usually the patient suffers great painasjong as the dislocation remains unreduced. Watson, of New York, saw a case of complete dislocation of thepatella outwards in a fat young lady with lax fibre, and occasioned bydancing. He says the knee was slightly but firmly flexed. It wasreduced by a very slight pressure with the fingers, and although someinflammation with effusion into the joint ensued, the use of the limbwas completely restored in a week or ten Prognosis.—Reduction is in general easily accomplished, but a re-luxation is very prone to occu
