Evolution and characteristics of nocturnal knee pain after knee arthroplasty.
Nocturnal knee pain and sleep disorders are two common but poorly studied issues contributing to dissatisfaction following knee arthroplasty. This study aims to evaluate the prevalence and associated factors of nocturnal pain and sleep disturbance in a population undergoing knee arthroplasty. ⋯ Bad sleeping quality is present in 54% of knee arthroplasty patients before and after surgery. Nocturnal pain is present in 39% of knee arthroplasty patients before surgery and this drops to 3% after one year. Nocturnal pain is associated with higher pain intensity, neuropathic symptoms, increased medication consumption and poor sleeping quality. Night pain disappeared faster after UKA than TKA, with a tipping point around 6 weeks postoperatively.

Differences in gait analysis and clinical outcome after dynamic fixation or screw fixation in acute syndesmosis tear: a prospective randomized pilot study.
Acute syndesmosis tears can be treated by static screw or dynamic fixation. Various studies have compared these techniques regarding postoperative outcome. However, to our knowledge, no study has used 3D-instrumented gait analysis (IGA). We hypothesized that a dynamic fixation would perform non-inferior to screw fixation in terms of biomechanical and clinical outcomes. ⋯ Our study demonstrated that dynamic fixation has better or similar biomechanical and clinical outcomes compared to screw fixation. Future research should focus on biomechanical differences during gait as well as clinical outcomes in case of earlier weight-bearing after dynamic fixation.

Hallux valgus deformity severity is one determent for the surgical procedure for hallux valgus (HV) correction. HV deformities are usually classified into mild/moderate/severe. The aim was to investigate the cut-off criteria used to classify HV deformity. ⋯ Level I, systematic review of randomized controlled trials and prospective comparative studies.

The role of acetabular cement augmentation in 2-stage revision arthroplasty for prosthetic joint infection of the hip.
In the treatment of chronic prosthetic joint infection (PJI) of the hip, two-stage exchange arthroplasty is commonly employed. Various spacer designs, including Hemi-Spacers and Articulating Spacers, are utilized during this process. However, these spacers are associated with a high rate of mechanical complications and pose a risk of progressive bone loss. This study aims to compare these two types of spacers in terms of mechanical complications, center of rotation (COR) restoration, and preservation of acetabular bone stock. ⋯ Dynamic spacers with acetabular cement augmentation help preserve peri-acetabular bone stock and prevent progression of acetabular bone erosion during the inter-stage period. Additionally, these spacers reduce the dislocation rates, making reimplantation easier and leading to better restoration of hip biomechanics during the second procedure.

What are the age-related factors linked to aseptic revisions in constrained and unconstrained TKA as well as UKA? A register-based study from the German arthroplasty registry (EPRD).
The implantation rate of total knee arthroplasties (TKA) is continuously growing. Aseptic problems are a major cause of revision. The aim of the following study was to determinate the incidence of aseptic revisions in primary knee arthroplasty as well as aseptic revision rates and influencing factors according to the patients' age and type of procedure. ⋯ III, cohort study.
