[Quality criteria in arthroplasty].

Max Jaenisch, Karl Dieter Heller, Dieter Christian Wirtz,

The discipline of orthopedics and trauma surgery strives for constant improvement of the quality of results in arthroplasty; however, in order to enable targeted alterations to the establish standard operating procedures, dedicated documentation of the current quality of results is necessary. This can be achieved by so-called external quality assurance, ... Read more >>

Hip Abductor Deficiency after Total Hip Arthroplasty: Diagnostic and Therapeutic Methods.

David Richard Krüger, Karl-Dieter Heller,

Abductor deficiency after total hip arthroplasty is a severe complication with functional limitations and a significant reduction in the patient's quality of life. Common causes are degenerative ruptures or approach-related iatrogenic damage to the gluteus medius and minimus muscle and the inferior gluteal nerve, fractures of the greater trochanter and ...

Blood transfusion and venous thromboembolism trends and risk factors in primary and aseptic revision total hip and knee arthroplasties: A nationwide investigation of 736,061 cases.

Elke Jeschke, Mustafa Citak, Andreas M Halder, Karl-Dieter Heller, Fritz U Niethard, Peter Schräder, Josef Zacher, Hanna Leicht, Jürgen Malzahn, Christian Günster, Thorsten Gehrke,

<h4>Background</h4>Over the last years, new transfusion guidelines and pharmaceuticals have been introduced in primary and revision total hip and knee arthroplasty (P-THA, P-TKA, R-THA, R-TKA). In the US, a substantial decrease in transfusions has been observed in recent years. Little data exists on the subject in Europe. In this context ... Read more >>

[Very rare cases of periprosthetic malignant neoplasms : Data from 4000 cases of endoprosthetic joint replacements from the histopathologic implant register].

Kevin Keidel, Marc Thomsen, Christian Dierkes, Holger Haas, Ingo Arnold, Karl-Dieter Heller, Vincent Krenn, Martin Liebisch, Mike Otto, Thorsten Gehrke, Veit Krenn,

BACKGROUND:In 2016, the AG 11 (work group for implant-material-intolerance) of the German society for Orthopaedics and Orthopaedic Surgery (DGOOC) created a histopathologic implant register (HIR). The goal was to conduct a retrospective data analysis based on the revised SLIM-consensus-classification, which defines eight different failure mechanisms. QUESTIONS:The analysis of 4000 cases of endoprosthetic joint replacements ... Read more >>

Low Hospital Volume Increases Re-Revision Rate Following Aseptic Revision Total Knee Arthroplasty: An Analysis of 23,644 Cases.

Andreas M Halder, Thorsten Gehrke, Christian Günster, Karl-Dieter Heller, Hanna Leicht, Jürgen Malzahn, Fritz U Niethard, Peter Schräder, Josef Zacher, Elke Jeschke,

<h4>Background</h4>Along with rising numbers of primary total knee arthroplasty (TKA), the number of revision total knee arthroplasties (R-TKAs) has been increasing. R-TKA is a complex procedure requiring special instruments, implants, and surgical skills. Therefore it is likely that hospitals with more R-TKAs have more experience with this type of surgery ...

Low Hospital Volume Increases Revision Rate and Mortality Following Revision Total Hip Arthroplasty: An Analysis of 17,773 Cases.

Elke Jeschke, Thorsten Gehrke, Christian Günster, Karl-Dieter Heller, Hanna Leicht, Jürgen Malzahn, Fritz Uwe Niethard, Peter Schräder, Josef Zacher, Andreas M Halder,

<h4>Background</h4>With the number of primary total hip arthroplasty (THA), the amount of revision THA (R-THA) increases. R-THA is a complex procedure requiring special instruments, implants, and surgical skills. Therefore it is likely that hospitals performing a higher number of R-THAs have more experience with this type of surgery and therefore ... Read more >>

Obesity Increases the Risk of Postoperative Complications and Revision Rates Following Primary Total Hip Arthroplasty: An Analysis of 131,576 Total Hip Arthroplasty Cases.

Elke Jeschke, Mustafa Citak, Christian Günster, Andreas M Halder, Karl-Dieter Heller, Jürgen Malzahn, Fritz U Niethard, Peter Schräder, Josef Zacher, Thorsten Gehrke,

BACKGROUND:The aim of our study is to evaluate the association of body mass index (BMI) and the risk of postoperative complications, mortality, and revision rates following primary total hip arthroplasty given other potentially confounding patient characteristics in a large cohort study. METHODS:Using nationwide billing data for inpatient hospital treatment of ... Read more >>

Are TKAs Performed in High-volume Hospitals Less Likely to Undergo Revision Than TKAs Performed in Low-volume Hospitals?

Elke Jeschke, Mustafa Citak, Christian Günster, Andreas Matthias Halder, Karl-Dieter Heller, Jürgen Malzahn, Fritz Uwe Niethard, Peter Schräder, Josef Zacher, Thorsten Gehrke,

<h4>Background</h4>High-volume hospitals have achieved better outcomes for THAs and unicompartmental knee arthroplasties (UKAs). However, few studies have analyzed implant survival after primary TKA in high-volume centers.<h4>Questions/purposes</h4>Is the risk of revision surgery higher when receiving a TKA in a low-volume hospital than in a high-volume hospital?<h4>Methods</h4>Using nationwide billing data of the ...

Indication Criteria for Total Knee Arthroplasty in Patients with Osteoarthritis - A Multi-perspective Consensus Study.

Jochen Schmitt, Toni Lange, Klaus-Peter Günther, Christian Kopkow, Elisabeth Rataj, Christian Apfelbacher, Martin Aringer, Eckhardt Böhle, Hartmut Bork, Karsten Dreinhöfer, Niklaus Friederich, Karl-Heinz Frosch, Sascha Gravius, Erika Gromnica-Ihle, Karl-Dieter Heller, Stephan Kirschner, Bernd Kladny, Hendrik Kohlhof, Michael Kremer, Nicolai Leuchten, Maike Lippmann, Jürgen Malzahn, Heiko Meyer, Rainer Sabatowski, Hanns-Peter Scharf, Johannes Stoeve, Richard Wagner, Jörg Lützner,

<b>Background and Objectives</b> Knee osteoarthritis (OA) is a significant public health burden. Rates of total knee arthroplasty (TKA) in OA vary substantially between geographical regions, most likely due to the lack of standardised indication criteria. We set out to define indication criteria for the German healthcare system for TKA in ... Read more >>

[Impact of Case Numbers on the 5-Year Survival Rate of Unicondylar Knee Replacements in Germany].

Elke Jeschke, Thorsten Gehrke, Christian Günster, Karl-Dieter Heller, Jürgen Malzahn, Axel Marx, Fritz-Uwe Niethard, Peter Schräder, Josef Zacher, Andreas Matthias Halder,

<h4>Background</h4>Reported survival rates of unicondylar knee arthroplasty (UKA) vary considerably. The influences of patient characteristics and the type of implant have already been examined. This analysis investigated the influence of hospital volume on 5-year-survival rate, using administrative claims data of Germany's largest health insurance provider.<h4>Methods</h4>We analysed administrative claims data for ...

Patient selection for shorter femoral stems.

Andreas Gruner, Karl-Dieter Heller,

The right patient selection with the correct surgical treatment are prerequisite for a positive result in total hip arthroplasty (THA). Short stem implants demand a shorter anchoring length in accordance with the proper indication. Although appropriate indications for short stems have been discussed in the literature, there currently is no ... Read more >>

CD38 low IgG-secreting cells are precursors of various CD38 high-expressing plasma cell populations.

Sergio Arce, Elke Luger, Gwendolin Muehlinghaus, Giuliana Cassese, Anja Hauser, Alexander Horst, Katja Lehnert, Marcus Odendahl, Dirk Hönemann, Karl-Dieter Heller, Harald Kleinschmidt, Claudia Berek, Thomas Dörner, Veit Krenn, Falk Hiepe, Ralf Bargou, Andreas Radbruch, Rudolf A Manz,

Despite the important role immunoglobulin G (IgG)-secreting plasma cells play in memory immune responses, the differentiation and homeostasis of these cells are not completely understood. Here, we studied the differentiation of human IgG-secreting cells ex vivo and in vitro, identifying these cells by the cellular affinity matrix technology. Several subpopulations ... Read more >>

D C Wirtz, K D Heller, U Holzwarth, C Siebert, R P Pitto, G Zeiler, B A Blencke, R Forst,

We present the early results of 142 uncemented femoral stem revisions using the modular MRP-Titan system. There were 70 cases with marked preoperative femoral bone defects (Paprosky type 2C and type 3); and bone grafts were used in 31 cases. At a mean follow-up of 2.3 years five cases were ...
