Comparative StudyIntraoperative cartilage analysis of the first carpometacarpal joint - comparison with conventional staging according to Eaton and Littler.
Osteoarthritis of the first carpometacarpal joint is a common pathology of the hand, which may show an increasing prevalence in Germany due to the demographic development. In recent years, not only the current gold standard - the resection arthroplasty of the thumb saddle joint - has been used, but also therapeutic thumb saddle joint arthroscopy. In addition to the patient's clinical complaints, radiographic diagnostics have been used to decide on treatment, although it has not been proven whether there is a correlation between imaging and clinical complaints. ⋯ III.

Comparative StudyModern cementless acetabular cups in total hip arthroplasty performed for primary osteoarthritis: a comparative registry study.
Comparative studies evaluating the different material and surface finishing of acetabular components in total hip arthroplasty (THA) are lacking. Using a regional arthroplasty registry, the survival rates and the hazard ratios of different cups in THA performed for primary osteoarthritis were assessed, using endpoints: (1) every cup failure, (2) cup aseptic loosening, (3) periprosthetic infection. ⋯ - 3D printed cups provided similar 10-year outcomes compared to ultraporous cups and second-generation cups. - There is no additional risks of aseptic loosening and infection.

Comparative StudyComparison of early outcomes of primary total knee arthroplasties performed using subvastus and medial parapatellar approaches and evaluation of quadriceps muscle elastography.
In primary total knee arthroplasty (TKA) surgeries, the medial parapatellar (MP) and subvastus (SV) approaches are frequently employed. The SV approach involves preserving the vastus medialis muscle, leading to debates about the possibility of earlier healing of the extensor mechanism. Shear wave elastography (SWE) is known for monitoring tissue healing. In this study, our research question revolves around whether there exist differences in tissue healing following MP and SV approaches. Unlike previous studies, we aim to investigate this difference using solely SWE, which provides a quantitative measurement specifically targeting the vastus medialis muscle. ⋯ Both MP and SV approaches demonstrate similar and favorable early outcomes in TKA surgery. The preservation of the vastus medialis in the SV approach does not lead to significant differences in clinical scores or muscle recovery compared to the MP approach.

Observational StudyEvolution 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.

Correlation of lower limb alignment with medial mensical extrusion in knee osteoarthritis.
This study aims to explore the relationship between Lower limb alignment parameters and the degree of Medial Meniscal Extrusion (MME) in patients with Knee Osteoarthritis (KOA), in hopes of providing new reference data for the prevention and treatment of KOA. ⋯ AMA, JLCA, and mLDFA are closely related to the degree of MME in KOA patients and can serve as important parameters for assessing the severity of MME, holding significant implications for the early prevention and treatment of KOA.
