Reverse shoulder arthroplasty in revision surgery-Indications and results.

Background: The number of reverse shoulder arthroplasty (RSA) procedures performed worldwide has increased over the last 10 years, with a corresponding increase in revision shoulder arthroplasty (SRSA). SRSA is often used for post-traumatic revision surgery in cases of infections and failure of anatomical prostheses. Data on outcomes with specific detail for each indication for the prosthetic solution as a secondary treatment are scarce, and inhomogeneous.

Risk of bacterial colonization by torniquet during arthroscopy of the knee joint.

Purpose: The following study investigated the risk of transmission or spread of potentially pathogenic bacteria via surgical gloves and/or with an elastic bandage to achieve a bloodless surgical site during arthroscopy.

Methods: This was a single-center, prospective study performed at a level-1 trauma center. The included patients were between 18 and 65 years of age and underwent arthroscopy of the knee joint.

Engineering, feasibility, and safety of force-controlled oropharyngeal swabs with a 3D-printed feedback system FCCSS (force controlled COVID-19 swab study) - a preliminary study.

Errors in laboratory diagnostics of viral infections primarily occur during the preanalytical phase, which is especially observed in sample collection. Hitherto, no efforts have been made to optimize oropharyngeal smears. An accurate method to analyze the necessary conditions for a valid oropharyngeal smear test is required, especially to avoid false negative results, which can lead to promotion of the spread of viruses such as SARS-CoV-2.

Comparison of needle and conventional arthroscopy for visualisation of predefined anatomical structures of the knee joint: a feasibility study in human cadavers and patients.

Background: In terms of the optics used for Knee arthroscopy, a large number of different endoscopes are currently available. However, the use of the 30° optics in knee arthroscopy has been established as the standard procedure for many years. As early as the 1990s, needle arthroscopy was occasionally used as a diagnostic tool.

Anatomic repair and ligament bracing as an alternative treatment option for acute combined PCL injuries involving the posteromedial or posterolateral corner-results of a multicentre study.

Methods: Sixteen prostheses from 13 patients with suspected PJI were prospectively examined using PET/MRI. Image datasets were evaluated in consensus by a radiologist and a nuclear physician for the overall diagnosis of 'PJI' (yes/no) and its anatomical involvement, such as the periprosthetic bone margin, bone marrow, and soft tissue.

Online consultation in an orthopedic trauma surgery outpatient clinic: is there a learning curve?

Background: In the context of the German contact restrictions due to the COVID-19 pandemic of March 2020, an online-based consultation system was established in our university orthopedic outpatient department to maintain patient care. As a basis for contact-minimizing communication, this was continued after the contact restrictions were lifted. The aim of this prospective pilot study was to assess the effectiveness, technical feasibility, and patient flow in this system under lockdown conditions and in the period afterwards.

Germany has a high demand in meniscal allograft transplantation but is subject to health economic and legal challenges: a survey of the German Knee Society.

Purpose: To determine the current status and demand of meniscal allograft transplantation (MAT) in Germany among members of the German Knee Society (= Deutsche Kniegesellschaft; DKG).

Methods: An online survey was conducted between May 2021 and June 2021 and sent to all members of the DKG. The survey questionnaire consisted of 19 questions to determine the demand and technical aspects of MAT among the participants and to identify areas of improvement in MAT in Germany.

[Posterior meniscus root tears].

Meniscus root tears are radial tears in the region of the posterior insertion zones. Medial root injuries usually occur in individuals > 50 years of age without adequate trauma and are associated with obesity and varus deformities. The root lesion leads to a loss of ring tension, which results in extrusion of the meniscus and a strong increase in joint pressure that is biomechanically equivalent to a complete meniscectomy.

[Potential of inpatient cases of a university hospital for orthopedics and trauma surgery for outpatient care].

Background: The act of the Medical Service of the Health Funds (MDK) is intended to shift health services previously provided in inpatient care to the outpatient care sector in accordance with § 115b SGB V. The aim of this study was the investigation of potential groups of inpatient cases of a university hospital for trauma surgery and orthopedics, which might be at risk for transfer to surgical outpatient treatment.

Methods: Data collection using SAP Data Warehouse included all inpatient cases 2017-2019, with subgroup analysis of economic parameters of three risk groups (RG): 1) primary misallocation, 2) procedures of AOP categories 1 and/or 2 and 3) elective 1‑day cases.
