Our purpose was to describe an unusual series of 21 patients with fungal osteomyelitis after an anterior cruciate ligament reconstruction (ACL-R). We present a case-series of consecutive patients treated at our institution due to a severe fungal osteomyelitis after an arthroscopic ACL-R from November 2005 to March 2015. Patients were referred to our institution from different areas of our country. We evaluated the amount of bone resection required, type of final reconstructive procedure performed, and Musculoskeletal Tumor Society (MSTS) functional score.Aims
Methods
The purpose of this study is to determinate if the inoculation of chondrocytes under periosteal flaps does improve the chondrogenic potential of periosteal flaps.
Chondrocyte and Fibroblast Implantation: A parapatellar incision was performed on both knees. Defect was cleaned and on study group the periosteum taken from the tibia was sutured leaving one edge free to inoculate the chondrocytes or fibroblast according to group using a needle Then the defect was closed using fibrin glue. The animals were euthanatized 8 months postoperative.
The ACI group showed a tissue type means II (ICRS) (95% CI: 28–99%) Collagen type 2 was evident only in the deep layers. The fibroblast group did show a reparative tissue, tissue type mean II (95% CI: 28–99%) Collagen type 2 was evident in deep layers DISCUSSION: According to this study the inoculation of chondrocytes under periosteal flaps does not improve significally the chondrogenic potential of periosteal flaps.(p: 0,77). Comparing the same procedure with chondrogenic and non chondrogenic cell lines could determinate the role of different chondrogenic components (periosteum and chondrocytes). Probably the chondrogenic capacity of the periosteum is sufficient to stimulate a reparative tissue. However none of these procedures could establish an adult normal cartilage hyaline tissue.
