Revision of a patient with periprosthesis infection (a–c) and a patient with loosening of prosthesis (d–f). An abscess was observed 4 months after the operation as indicated by the arrow (a). Surgical debridement was performed to remove the infected prosthesis, and bone cement spacer containing antibiotics was implanted (b). The bone cement spacer was replaced by the prosthesis when there were no signs of infection (c). An extension prosthesis was applied for a boy with osteosarcoma in the left femur (d). The prosthesis was loosening 1 year after the operation (e). A new prosthesis with plate and screw was used to replace the loose one (f)
