This case report presents a traumatic intra-articular patellar dislocation - associated intercondylar fracture of the distal femur - and the consequent arthroscope assisted reduction and percutaneous screw fixation. To the best of our knowledge, this is the first case in which the arthroscope assisted operative reduction and percutaneous screw fixation of the fracture fragment has been demonstrated. Our patient was a 55-year-old female who was treated by the aforementioned method which concluded with excellent results.  Kulcsszavak: arthroscopy, dislocations, femoral fractures, patella
