  ABSTRACT: Der Fall einer 18-jährigen Patientin mit einem ausgedehnten intraartikulären Tumor des rechten Hüftgelenks und einer sekundärer Osteolyse am Schenkelhals wird dargestellt. Magnetresonanztomographie (MRT) und Biopsie ergaben die Diagnose einer fokalen villonodulären Synovitis. Durch die Hüftarthroskopie konnte der Tumor komplett entfernt und die Osteolyse mit einem exzellenten klinischen Ergebnis vollständig ausgeräumt werden. Die Hüftarthroskopie hat den Vorteil des geringeren Operationstraumas und des sehr guten frühfunktionellen Ergebnisses. Auch ausgedehnte intraartikuläre Tumore können im Einzelfall vollständig durch Hüftarthroskopie behandelt werden. We present the clinical case of an 18-year-old woman who complained of acute hip pain. MRI showed an intra-articular tumor 4cm in size with osteolysis (18 mm) on the distal region of the femoral head-neck junction. Focal pigmented villonodular synovitis infiltrating the bone was diagnosed. A complete resection of the tumor including the osteolytic area was done by an arthroscopic procedure. There was no sign of relapse after 8 months of follow-up, with no pain and complete function of the hip. Arthroscopic treatment has the advantage of minimal surgical trauma and good mid-term results for treating a focal lesion in selected cases.

  ABSTRACT: Intra-articular injuries are common after dislocation and fracture of the hip joint and can be addressed using hip arthroscopy. The most common indications for this procedure are loose bodies, labral tears and chondral defects. In addition, preexisting femoroacetabular impingement can be addressed at the time of surgery. Arthroscopically guided fracture reduction and fixation has been described. We present two case reports of intra-articular lesions after traumatic hip dislocation. The first is a case of a man with an anterior labral tear and loose bodies after closed hip reduction. The second case is a man with a large anterior labral tear with preexisting femoroacetabular impingement. Both of them were treated by arthroscopic debridement of the unstable labrum. In addition loose bodies were removed in the first patient and a femoral osteoplasty was performed in the second patient. Hip arthroscopy has proven to be a safe and effective surgical technique for treating specific post-traumatic lesions and preexisting femoroacetabular impingement. The current case reports provide an overview of the indication for hip arthroscopy following traumatic injuries to the hip.
