Meta AnalysisSurgical treatment is better than non-surgical treatment for primary patellar dislocation: a meta-analysis of randomized controlled trials.
At present, the best treatment for primary patellar dislocation (PPD) has not been unified. Moreover, meta-analyses comparing the non-surgical and surgical treatments of PPD are lacking. Thus, we aimed to compare the clinical efficacy of surgical or non-surgical treatment of PPD. ⋯ Surgical treatment can provide better clinical results in a short period of time, and patients may achieve good results within 10 years owing to the advances in surgical techniques and instruments. Thus, we recommend surgical treatment as the preferred treatment for primary patellar dislocation.

Morphometric measurement and applicable feature analysis of sacral alar-iliac screw fixation using forward engineering.
To evaluate S1AI-S4AI screw channels with three-dimensional digital technology simulation analysis and to study the feasibility and applicable features of sacral alar-iliac screw fixation in adults. ⋯ Only one maximum ideal screw can be placed on one side at a time. With a radius of 2.50 mm considered to be standard, it is feasible to place S1AI-S3AI screws with a radius > 2.50 mm in the entire adult population and S4AI screws with a radius > 2.50 mm in some of the adult population. Furthermore, preoperative three-dimensional reconstruction and three-matic research software can effectively simulate the sacral alar-iliac screw channels, and they can provide accurate data for clinical applications.

Do anticoagulants affect outcomes of hip fracture surgery? A cross-sectional analysis.
The management of patients with a hip fracture is affected by the use of oral anticoagulants. A cross-sectional analysis was undertaken to investigate health outcome differences in those anticoagulated compared to those not anticoagulated. ⋯ There was no statistically significant difference in health outcomes between those anticoagulated and those not after adjusting for patient characteristics. It was feasible to avoid significant delay in hip fracture surgery in those anticoagulated.

Hip abductor tendon pathology visualized by 1.5 versus 3. 0 Tesla MRIs.
Hip abductor tendinopathies are becoming increasingly recognized as clinically relevant disorders. However, knowledge about prevalence of abductor tendinopathies and associated disorders of adjacent hip articular and periarticular structures is limited. In this context, the relative diagnostic value of 1.5-T vs. 3.0-T MRI magnets has not been studied yet. ⋯ Peritrochanteric lesions are a prevalent pathology that should specifically be looked for, preferably by 3.0-T MRI, independent of concomitant hip joint pathology.

Mid-term results after revision total hip arthroplasty with custom-made acetabular implants in patients with Paprosky III acetabular bone loss.
Severe acetabular bone loss, both with or without pelvic discontinuity, remains a challenge in revision total hip arthroplasty (RTHA). The goal of our study was to evaluate the mid-term results for consecutive patients with Paprosky III acetabular bone loss with or without pelvic discontinuity who needed RTHA with custom-made acetabular implants and to compare the results to those of other studies. ⋯ Defect reconstruction with custom-made modular acetabular implants can be a good, nevertheless expensive, treatment option with clinically and radiologically satisfying results in comparison to recent studies in the literature. Nevertheless, high postoperative complication rates, especially in terms of PJI, remain a challenge.
