Die Standzeit von Endoprothesen großer Gelenke hat in den letzten Jahrzehnten zugenommen. In einer nordamerikanischen Studie wurde für Hüftendoprothesen eine 10-Jahres-Standzeit von 94% ermittelt, europäische Daten weisen Standzeiten von 88–95% aus. Aus Sicht des Pathologen ergeben sich ätiologisch folgende wesentliche Erkrankungsgruppen für die „Pathologie(More)
Secondary patella resurfacing is a controversial procedure which is applied in patients with anterior knee pain after a bicondylar knee arthroplasty (with unresurfaced patella). A group of 46 patients were submitted to this procedure and their satisfaction, range of motion and pain improvement was evaluated. 52.2% of the patients were satisfied with the(More)
Total ankle arthroplasty is increasingly used as an alternative to arthrodesis to treat advanced ankle arthritis. However, the outcomes and postoperative complications are poorly described. Between March 2005 and May 2010 114 S.T.A.R. prostheses were implanted by one surgeon at our institution. We retrospectively analysed the demographics, clinical outcomes(More)
There still is no consensus on the treatment of choice in revision knee arthroplasty associated with severe femoral and/or tibial bone loss. A total of 44 patients underwent revision knee arthroplasty procedures using porous tantalum cones (TM cones) to reconstruct tibial and/or femoral bone defects. At latest follow up after 37 months (32-48), 38 patients(More)
BACKGROUND Total knee arthroplasty (TKA) revisions are increasing due to the rising numbers of primary cases, younger patients and an aging population. The technical demand of these procedures is incomparable higher than in primary cases. Also the expectable clinical results are inferior. Measures to improve the clinical results are desireable.(More)
Radiographic signs of osseointegration with the use of fluted, tapered, modular, titanium stems in revision hip arthroplasty with bone loss have not been previously categorized. Serial radiographs of 64 consecutive hips with mean follow-up of 6.2 years were retrospectively reviewed. Bone loss was classified as per Paprosky classification, osseointegration(More)
A consecutive series of 100 primary total hip arthroplasties were performed at a single institution on 87 patients using a cementless collared titanium press-fit stem. Of patients, 87% received a hemispheric porous-coated cup, and 13% received a nonmodular titanium fibermesh press-fit cup. Ten hips were excluded from the longer-term evaluation: 6 were lost(More)
We report a single-surgeon experience with a noncemented modular revision shaft (Modular Prosthesis; LINK, Hamburg, Germany) with clinical and radiographic results of 63 patients after 10 years. The Harris Hip Score improved from 51 to 84 points. Intraoperative complications included 11 fractures. Four patients had postoperative femoral fractures. Further(More)
Within the past 5 years, the oral anticoagulants rivaroxaban, apixaban, and dabigatran etexilate have been approved for the prevention of venous thromboembolism in adult patients after elective hip or knee arthroplasty in the European Union and many other countries worldwide. These agents differ from the previously available anticoagulants because they(More)
