Veterinary notes for horse owners : a manual of horse medicine and surgery . fake appearance of being tied in below the knee. BROKEN KNEES. 95 Over the front of the knee pass^es the broad, flat tendon, of the muscle(extensor metacarpi magnus) which extends that joint. Between this tendonand the bones of the knee, in order to prevent friction, are placed two bur^eor sacs, which contain synovia (joint oil). As thes^e burste partly overlap thetendon externally, they are liable to become wounded when the tendon is laidbare by the animal coming down. On the outside front, if I may use theterm, passes the tendon of the muscle which serves to extend the foot (extensorpedis. Fig. 7). There is also a small oblique extensor tendon which passesacross the knee ; and the skin, with its loose underlying tissue, finally coversthe whole part. The tendon of the extensor pedis, except in extremely grave cases, is, onaccount of its side position, hardly ever laid bare or injured. Here, the principles which should guide our treatment, are thoseof Wounds on or near Joints (p. 91).. Fig. 40.—Cradle. TREATMENT.—The object of our treatment should be to obtainrepair with the least possible destruction of tissue, in order to limitthe extent of the subsequent blemish as much as practicable, andto obviate the danger of the wound extending into the joint. Hence,strict antiseptic measures (p. 69) should be adopted. Poulticingor continued fomentations should on no account be employed; forthey tend to destroy the vitality of the part, and to encourage sup-puration, Which is always accompanied by destruction of tissue. Inall cases, we should by tying the horse up, or by using a cradle(Fig. 40), prevent him from injuring his bad knee. H dirt or grithas entered the Avound, it may be removed by bathing the partwith warm water for a few minutes ; but if there is no foreign bodyin the cut, or if the skin is not divided, the application of water willserve no useful purpose.
