Aims Histology is widely used for diagnosis of persistent infection during reimplantation in two-stage revision hip and knee arthroplasty, although data on its utility remain scarce. Therefore, this study aims to assess the predictive value permanent sections at relation reinfection risk, compare results frozen sections. Methods We retrospectively collected from 226 patients (90 hips, 136 knees) with periprosthetic joint who underwent between August 2011 September 2021, a minimum follow-up...
Although cemented total knee arthroplasty (TKA) is considered the standard fixation technique, emerging trend toward cementless has created need for a detailed comparison. In previous study, we reported 5-year results comparing and hybrid TKAs using same implant design. The purpose of this study was to assess long-term follow-up at minimum 10 years. Methods: A retrospective analysis performed on 120 (60 cementless, 60 cemented) conducted between 2003 2007. Demographic clinical data were...
Substantial bone loss following failed total knee arthroplasty (TKA) represents a major challenge in revision arthroplasty, that can require distal femoral reconstruction (DFR). In this study, we aimed to assess the clinical outcome and complication frequencies of individuals who underwent DFR with modular megaprostheses. Additionally, compare functional measures after these sophisticated cases an age-matched control group prostheses quantify potential function.A retrospective chart review...
Meta-diaphyseal fixation of straight, tapered, uncemented stems has been proven to be very reliable for total hip arthroplasty in 10 20 years follow-up studies. The aim the study was evaluate whether implant survival as well radiological and functional outcome have changed patients with a minimum 30 years.
Background: The use of rotating hinge (RH) prostheses for severe primary as well revision arthroplasty is widely established. Due to the steadily increasing number RH prostheses, we aimed assess complication frequencies, types and clinical outcomes a modern prosthesis using new bearing material with minimum follow-up 7 years. Methods: Fifty-six consecutive patients who received EnduRo® carbon-fiber reinforced poly-ether-ether-ketone (CFR-PEEK) were included in this prospective study: 21...
Distal femur replacement is frequently used for limb salvage after bone tumor resections. It also in patients with severe loss because of traumatic conditions or revision TKA. Some studies on distal reported revision-free survival without distinguishing between oncologic diagnoses and those without, although these might be incomparable their differences important patient- disease-specific characteristics. This may lead to an inaccurate undifferentiated interpretation the results analyses.(1)...
Abstract Administration of bisphosphonates following total joint arthroplasty might be beneficial to reduce aseptic loosening. However, their effects on peri‐implant bone formation and bone–implant interface strength have not been investigated yet. We used a physiologically loaded mouse implant model investigate the short‐term postoperative systemic alendronate osseointegration. A titanium with rough surface was inserted in proximal tibiae 17‐week‐old female C57BL/6 mice ( n = 44)....
Aneurysmal bone cysts (ABC) are benign tumors mostly occurring in children and young adults. Different open minimal invasive surgical approaches have been proposed for the treatment of ABCs yet no consensus is defined to date. The aim this study was retrospectively review data a large single center series with patients treated by curettage or without filling cavity en-bloc resection. Questions/purposes We asked: (1) What local recurrence rate ABC after at our institution? (2) were positive...
Multiple revision hip arthroplasties and critical trauma might cause severe bone loss that requires proximal femoral replacement (PFR). The aim of this retrospective study was to analyse complication- revision-free survivals patients who received modular megaprostheses in an attempt reconstruct massive non-neoplastic defects the femur. Questions/purposes (1) What were general complication rates following PFR? (2) is incidence specific survivals? (3) risk factors leading a diminished PFR...
Background/Objectives: We evaluated the outcomes of patients undergoing en bloc total vertebrectomy at our institution within last three decades. The aim study was to analyse oncological and neurological changes over time. Methods: included 22 consecutive treated with a between January 1990 December 2022. standard follow-up protocol for sarcoma performed. Early complications were defined as first months postoperatively. Local recurrence reoccurrence tumour least four after surgery. Adequate...
Several authors observed a loss of correction after performing Chiari pelvic osteotomy (CPO) in young patients. Hence, the aim this study was to answer two questions: (1) Does affect development acetabulum skeletally immature patients long term? (2) Is there any evidence previously described “Anti-Chiari” effect mean follow-up 36 years? Data from 21 (27 hips) undergoing CPO before age 16 years were clinically assessed, and evolution radiological parameters over time analyzed. The at 11.2...
The use of rotating hinge (RH) prostheses for severe primary as well revision arthroplasty is widely established. Aim this study was to investigate long term results a new RH prosthesis (EnduRo®, B Braun, Germany), which uses carbon-fiber reinforced poly-ether-ether-ketone (CFR PEEK) bearing material, first time used in knee arthroplasty. Fifty-six consecutive patients, who received the EnduRo® were included prospective study: 21 patients (37.5%) total (TKA) and 35 (62.5%) underwent...
Fragestellung Die endoprothetische Rekonstruktion des gesamten Femurs stellt eine hochspezielle Operationsmethode dar, die prinzipiell für Tumorendoprothetik entwickelt wurde. In Fällen mit hochgradigen, multiplen Komplikationen nach Hüft- und Knietotalendoprothesen totale Femurrekonstruktion häufig einzige extremitätenerhaltende Versorgungsmethode dar. Neben der Möglichkeit raschen Mobilisierung ist Methode jedoch einem hohen Komplikationsrisiko behaftet.

The adult acquired flatfoot is a deformity with slow progression, which may leads to pain and restrictions of activities daily living if untreated. Various treatment strategies, depending on the clinical radiological presentation, exist. Therefore, an individual therapy approach necessary for optimal treatment. This article covers etiopathologic aspects, conservative operative treatments as well postoperative mobilization rehabilitation.Der erworbene Plattfuß des Erwachsenen präsentiert sich...
