Material type: materialTypeLabelBookPublisher: 1996Subject(s): Department of Clinical Medicine & SurgeryDDC classification: 0491,T Dissertation note: Cutaneous injuries particularly when quite massive are burning problems for the working clinicians. Healing in such injuries is unduly prolonged with subsequent granulation and scar formation resulting in uncosmetic look of the skin. Wounds of the canine knee have plagued both the veterinarian and the owners since long. Most of these wounds fail to respond to conventional methods of treatment. In such cases skin grafting serves as a good alternative for successful covering of the lesions. The study was done on 20 randomly selected mongrel dogs of either sex. A skin defect starting from 3 cm above and going the same distance down the joint encompassing the medial, cranial and lateral aspects was created and covered with a full thickness skin graft harvested from the lateral aspect of the thigh. In half of the dogs the grafts were fenestrated whereas in the other half they were kept unfenestrated. In each of the group the right knee was grafted fresh while the left knee underwent delayed grafting when the wounds were uniformly granulating without any clinical signs of infection. The animals were kept under observation for a period of 21- days. The survival rate of the unfenestrated grafts was 70% (7 out of 10) and 50% (5 out of 10) for the right and left limb respectively whereas in the fenestrated group the success rate was 90% (9 out of 10) in the right limb and 60% (6 out 10) in the left limb. The results indicated that the fenestrated grafts had an edge over the unfenestrated ones whether they were used to cover a fresh or an old granulating wound on the cranial aspect of the canine knee.

Cutaneous injuries particularly when quite massive are burning problems for the working clinicians. Healing in such injuries is unduly prolonged with subsequent granulation and scar formation resulting in uncosmetic look of the skin.

Wounds of the canine knee have plagued both the veterinarian and the owners since long. Most of these wounds fail to respond to conventional methods of treatment. In such cases skin grafting serves as a good alternative for successful covering of the lesions.

The study was done on 20 randomly selected mongrel dogs of either sex. A skin defect starting from 3 cm above and going the same distance down the joint encompassing the medial, cranial and lateral aspects was created and covered with a full thickness skin graft harvested from the lateral aspect of the thigh.

In half of the dogs the grafts were fenestrated whereas in the other half they were kept unfenestrated. In each of the group the right knee was grafted fresh while the left knee underwent delayed grafting when the wounds were uniformly granulating without any clinical signs of infection.

The animals were kept under observation for a period of 21- days. The survival rate of the unfenestrated grafts was 70% (7 out of 10) and 50% (5 out of 10) for the right and left limb respectively whereas in the fenestrated group the success rate was 90% (9 out of 10) in the right limb and 60% (6 out 10) in the left limb. The results indicated that the fenestrated grafts had an edge over the unfenestrated ones whether they were used to cover a fresh or an old granulating wound on the cranial aspect of the canine knee.
