Outcome after total ankle replacement or ankle arthrodesis in end-stage ankle osteoarthritis on the basis of german-wide data: a retrospective comparative study over 10 years.

Background: In symptomatic end-stage osteoarthritis of the ankle joint, total ankle replacement and ankle arthrodesis are the two primary surgical options for patients for whom conservative treatment fails. Published revision rates are often biased and difficult to compare. In this study, unplanned reoperation rates and revision rates were determined for both surgical interventions based on a large dataset, and risk factors for unplanned reoperations were identified.

[The German Association for Foot and Ankle (D.A.F.) registry on treatment of end-stage total ankle arthritis-what is its clinical impact?].

Initially established as a voluntary prosthesis register for total ankle replacement, the registry now enables analysis of revisions, complications, and clinical and functional outcomes-including patient-reported outcome measures-based on a period spanning more than 10 years. To allow analyses of the outcomes of ankle arthrodesis and supramalleolar osteotomies for treatment of end-stage arthritis in the future, the registry was extended by structured capturing of these procedures in 2018. While descriptive and analytical statistical evaluations of total ankle replacement are already possible today, the number of datasets on arthrodesis and supramalleolar osteotomies is still too small to support these analyses or comparative evaluations.

[Routine Practice Data for Health Care Analyses: Part 3 of the Manual].

Analyses of health and health care (hereafter referred to as "health care analyses") usually aim to make transparent the structures, processes, results and interrelationships of health care and to record the degree to which health care systems and their actors have achieved their goals. Health care-related data are an indispensable source of data for many health care analyses. A prerequisite for the examination of a degree of goal achievement is first of all an agreement on those goals that are to be achieved by the system and its substructures, as well as the identification of the determinants of the achievement of the objectives.

[Routine Practice Data for Evaluating Intervention Effects: Part 2 of the Manual].

The evaluation of intervention effects is an important domain of health services research. The ad hoc commission for the use of routine practice data of the German Network for Health Services Research (DNVF) therefore provides this second part of its manual focusing on the use of routine practice data for the evaluation of intervention effects. First, we discuss definition issues and the importance of contextual factors.

[Position paper of the German Network for Health Services Research (DNVF) on application-related data collection according to Social Code Book V].

Within the framework of the early benefit assessment, the Federal Joint Committee (G-BA) has been authorised since 2019 by the law for more safety in the supply of pharmaceuticals GSAV to request additional application-related data capture for certain pharmaceutical drugs. This results in certain challenges, especially in the area of conflict between methodological requirements and practical feasibility. The position paper provides an overview and takes up the general regulations defined by the Federal Ministry of Health (BMG) as well as the process defined by the G-BA.

[Manual for Methods and Use of Routine Practice Data for Knowledge Generation].

" There are more and more good reasons for using existing care data, with the focus in particular on the use of register data. The associated, clearly structured methodological procedure has so far been insufficiently combined, prepared and presented transparently. The German Network for Health Services Research (DNVF) has therefore set up an ad hoc commission for the use of routine practice data (RWE/RWD).

Intraoperative damage to surgical gloves during various operations on the musculoskeletal system: a multicenter study.

Introduction: Various orthopedic surgical procedures cause mechanical stress for gloves. In some cases, sharp-edged objects impact on the glove surfaces. The systematic description of lesions is still missing.

[Memorandum Registry for Health Services Research: Update 2019].

Health registries could be used to analyze questions concerning routine practice in healthcare. Therefore, registries are a core method in health services research. The German Network for Health Services Research (Deutsches Netzwerk Versorgungsforschung, DNVF) promotes the quality of registries by scientific exchange, organization of advanced training, and recommendations in the form of a memorandum "Registry for Health Services Research".

Using the Oxford Foot Model to determine the association between objective measures of foot function and results of the AOFAS Ankle-Hindfoot Scale and the Foot Function Index: a prospective gait analysis study in Germany.

Objective: After cross-cultural adaption for the German translation of the Ankle-Hindfoot Scale of the American Orthopaedic Foot and Ankle Society (AOFAS-AHS) and agreement analysis with the Foot Function Index (FFI-D), the following gait analysis study using the Oxford Foot Model (OFM) was carried out to show which of the two scores better correlates with objective gait dysfunction.

Design And Participants: Results of the AOFAS-AHS and FFI-D, as well as data from three-dimensional gait analysis were collected from 20 patients with mild to severe ankle and hindfoot pathologies.Kinematic and kinetic gait data were correlated with the results of the total AOFAS scale and FFI-D as well as the results of those items representing hindfoot function in the AOFAS-AHS assessment.

Pilot study for the registry of complications in rheumatic diseases from the German Society of Surgery (DGORh): evaluation of methods and data from the first 1000 patients.

Objective: Most patients suffering with rheumatic diseases who undergo surgical treatment are receiving immune-modulating therapy. To determine whether these medications affect their outcomes a national registry was established in Germany by the German Society of Surgery (DGORh). Data from the first 1000 patients were used in a pilot study to identify relevant corisk factors and to determine whether such a registry is suitable for developing accurate and relevant recommendations.

[Registries of the German Society for Orthopaedics and Trauma : Overview and perspectives of the DGU and DGOOC registries].

The register network of the German Society for Orthopaedics and Trauma (DGOU) consists of 14 registries that cover the various fields of traumatology and elective orthopedics. In addition to registries that focus on implants and types of diseases without age limitations, there are also registries dealing with special diseases in children and adolescents as well as the special needs of elderly patients with fractures. The registries serve as instruments for outcome research and quality assurance and can be used to develop treatment recommendations on a high level of evidence.

[Influence of registries on the quality of care].

Registries are a topic of lively debate amongst all stakeholders in healthcare, politics and economics. In general, registries are national or international (prospective) databases documenting the current state of diagnostic, therapeutic and long-term outcome variables of subjects with a distinct condition or health problem. The access to and handling of registry information is subject to strict legal, methodological and ethical principles and regulations before these data can be scientifically utilized and reentered into the routine daily practice.

[Rotator cuff repair: single- vs double-row. Clinical and biomechanical results].

Background: The goal of rotator cuff repair is a high initial mechanical stability as a requirement for adequate biological recovery of the tendon-to-bone complex. Notwithstanding the significant increase in publications concerning the topic of rotator cuff repair, there are still controversies regarding surgical technique.

Objectives: The aim of this work is to present an overview of the recently published results of biomechanical and clinical studies on rotator cuff repair using single- and double-row techniques.

Midterm Outcome after Mega-Prosthesis Implanted in Patients with Bony Defects in Cases of Revision Compared to Patients with Malignant Tumors.

Use of mega-prostheses is a common option for the treatment of patients with malignant tumors as well as in patients with large osseous defects at the time of revision surgery. No studies have compared the two groups to determine whether there is a relative difference in clinical outcomes. We performed a midterm-outcome-study to evaluate our results in these two patient populations.

[German Total Ankle Replacement Register of the German Foot and Ankle Society (D. A. F.) - presentation of design and reliability of the data as well as first results].

Introduction: Even though arthroplasty of the ankle joint is considered to be an established procedure, only about 1,300 endoprostheses are implanted in Germany annually. Arthrodeses of the ankle joint are performed almost three times more often. This may be due to the availability of the procedure - more than twice as many providers perform arthrodesis - as well as the postulated high frequency of revision procedures of arthroplasties in the literature.

Cartilage repair techniques of the talus: An update.

Symptomatic chondral or osteochondral defects of the talus reduce the quality of life of many patients. Although their pathomechanism is well understood, it is well known that different aetiologic factors play a role in their origin. Additionally, it is well recognised that the talar articular cartilage strongly differs from that in the knee.

Analysis of agreement between the German translation of the American Foot and Ankle Society's Ankle and Hindfoot Scale (AOFAS-AHS) and the Foot Function Index in its validated German translation by Naal et al. (FFI-D).

Background: Despite its wide use in clinical outcome measurement, there is yet no validated German language version of the AOFAS-AHS available. After finishing cross-cultural adaption of the AOFAS-AHS according to the AAOS guidelines, an analysis of agreement was carried out.

Methods: This was done by means of the 18-item Foot Function Index in its validated German translation by Naal et al.

[One-year outcomes for proximal femoral fractures: Posthospital analysis of mortality and care levels based on health insurance data].

Background: Proximal femur fractures are common and treatment is expensive. The aim of the present study was - after matching of hospital and health insurance data - to evaluate the influence of early operation on certain outcome parameters. Data from a German health insurance were used to identify then influence of the day of operation after admittance on the rate of mortality, decubitus, and revision surgery during the hospital stay and on the care level of the patients up to 1 year and in some cases longer after operation.
