The cells are then a paper comparing the periosteum and peri- cultured in a medium, which is composed of chondrium transplantations. The activated and expanded population of chondrocytes is Autologous Chondrocyte Implantation then reimplanted by arthrotomy exposure. In the last few years considerable interest and During the second operation the devitalized discussion has been focused on autologous tissue of the defect is excised, the base debrided, chondrocyte transplantation. In 1965, Smith,156 and a periosteum flap is harvested from the and in 1968, Chesterman and Smith30 had medial side of the medial upper part of the tibia already reported isolation of chondrocytes. The defect They had implanted these cells into articular is covered with this periosteum flap with the defects in rabbit humeri and into the iliac crest.

While the lesion may become a pale buy mycelex-g 100mg with mastercard, flesh-colored chronic lesion order mycelex-g 100mg free shipping, they rarely resolve spon- taneously. It is important to diagnose these early so that they can be treated at a more man- ageable stage. Biopsy will reveal specific histopathologic findings, if performed. FURUNCLES (PLATE 14) Furuncles are also commonly called “boils. Multiple or clustered furuncles are called carbuncles. Patients complain of pain, redness, and swelling at the affected site. The temperature may be elevated and there is often lymphadenopathy. CELLULITIS Cellulitis is an infection of the skin and subcutaneous tissue. The causative organism varies, although staphylococcal and streptococcal infections are common. Superficial cel- lulitis, erysipelas, is associated with streptococcal infections. The patient often describes a skin injury preceding the onset of redness, swelling, and pain at the site. The affected area is tender, swollen, reddened, and warm.
