The case of a 19-year-old male patient who complained of dull pain in his right knee for more than 18 months and was finally diagnosed with intracortical osteoid osteoma in the femoral diaphysis is presented. A new operative method was used to locate and remove the tumor. Under spinal anesthesia with the patient in the prone position, a lateral and a posterior approach were marked with special bone cutting tubes under computed tomographic control. The usual arthroscopic instruments (punch, retrograde suction stamp) were used to remove the nidus under arthroscopic visualization, thereby avoiding the disadvantages of open excisions, such as large incisions, bone loss, long hospitalization, and risk of infection. The advantages and disadvantages are thoroughly discussed and compared with conventional surgical procedures.
