Valgus stress radiographs have a minor additional value in detecting lateral cartilage wear when selecting patients for medial partial knee replacement.
A valgus stress radiograph, in addition to the weight-bearing fixed flexion posteroanterior radiograph (e.g., Rosenberg), is deemed useful to assess lateral cartilage wear by measuring lateral joint space width (JSW) in patients with medial knee osteoarthritis. This study aimed to assess: (1) the difference in measured lateral JSW between the Rosenberg and the valgus stress radiograph, and (2) the ability of the valgus stress radiograph to detect lateral cartilage wear (indicated by joint space narrowing) in patients where the Rosenberg radiograph showed full thickness cartilage (i.e., the additional value). ⋯ Although the valgus stress radiograph shows more lateral JSW narrowing compared to Rosenberg radiograph, it only has an additional value in 1 out of 17-25 patients with medial osteoarthritis. We, therefore, recommend a Rosenberg radiograph as routine radiographic assessment and only use an additional valgus stress radiograph in case of discrepancy between clinical and radiological findings.

E-scooter accidents-epidemiology and injury patterns: 3-year results from a level 1 trauma center in Germany.
Since the introduction of e-scooters in Germany in 2019, they are becoming more and more popular and associated injuries have increased significantly. The aim of this study was to assess the injury patterns after e-scooter accidents. ⋯ Our study shows one of the largest cohort of patients suffering e-scooter accidents in Europe. Compulsory helmet use, stricter alcohol controls and locking periods could contribute significantly to safety.

Mid-term results of a cementless hip stem in femoral revision: how much diaphyseal press-fit do we need?
The aim of this retrospective study was to analyze the clinical and functional outcome of a modular tapered revision hip stem after mid-term follow-up with a special focus on the length of the distal bicortical fixation of the cementless hip stem. ⋯ Clinicaltrials.gov registration: NCT04833634 registered on April 6, 2021.

Comparing outcomes in revision total hip arthroplasty in inpatient versus outpatient setting: a matched cohort analysis.
As the population ages, revision total hip arthroplasty (rTHA) is becoming more common. However, there is a paucity of literature regarding perioperative outcomes following inpatient versus outpatient rTHA. Our study aims to compare perioperative complications and readmission rates associated with rTHA in a large national cohort. ⋯ There were no difference in the odds of complications between outpatient primary and revision THA. Additionally, rTHA performed in an outpatient setting did not show any increase in immediate compared to inpatient settings. These findings suggest that rTHA can be safely performed on certain patients.
