32. The operation is seldom attended with much pain. Only one patient manifested signs of this in the practice of Desault. Nor have those operations of the kind performed in England been more painful, so that it may be laid down as a principle, that in most cases no primitive accident is to be dreaded. 33. With regard to hemorrhagy, as there is no large artery near the place of the incision, there is nothing to be apprehended on that score. Oftentimes there is scarcely any loss of blood at all, as may be seen in the first case published in the Journal of Surgery. But, even admitting that a small articular branch be divided, the reunion of the edges of the wound will be sufficient to check the hemorrhagy, in the same manner as in the operation for the hare-lip, the contact of the divided integuments of the lip, puts an end to the hemorrhagy from the small arteries of the part. § XIV. OF THE SUBSEQUENT TREATMENT. 34. I have already said that but little is to be apprehended on the score of accidents subsequent to the operation (26). Out of the numerous operations of the kind performed lately in Europe, but few cases have proved troublesome in their consequences, and even these were influenced by some foreign circumstances. Thus, for example, one of the patients of Simson rode out on horseback a few hours after the operation, on a cold and stormy day, and thus produced a troublesome affection of the part. A similar remark may be made respecting the case formerly mentioned (27). 35. The apparatus or dressing remains untouched for the two or three first days, during which time it is necessary to wet it frequently with vegeto-mineral water. It is a certain truth, that the use of this liquid retards the suppuration of wounds, and that, when continued a due length of time, it keeps inflammation at that degree most proper for the process of healing. 36. On the removal of the dressing, the wound is sometimes so perfectly healed up, as not to exhibit the least discharge. At other times a slight suppuration takes place; but, at the end of a few days, the cure is complete. Under the care of Desault, it was always effected in eight or ten days. 37. Let us bring the doctrine just laid down to the test of experience. Five cases have been published on this point. I have selected two of them, both which occurred in the same subject, where we find the same operation twice performed with equal success. CASE I. M. Vielle, aged nineteen, was attacked about the beginning of the year 1790, by a spontaneous swelling in the joint of the knee. Inconsiderable at first, but increased afterwards by a laborious journey, it disappeared at the end of two months, discovering to the touch, near the internal edge of the rotula, a foreign body, which was hard and moveable, and which somewhat impeded the motions of the joint.
