Sometimes, total knee replacement (TKR) is performed after a tibial osteotomy. It is not known if the osteotomy influences the clinical process of a TKR. The aim of this study was to look at the clinical outcome of a TKR after high tibial osteotomy (HTO) compared to a TKR with no HTO. ⋯ A HTO was not determinant for having a worse outcome at the TKR, even when there were radiographic differences. The coronal alignment with valgus deformity pre-TKR after a HTO showed better functional results than in the case of varus deformity. Level of evidence III.

Association of pre-treatment radiographic characteristics of calcaneal fractures on patient-reported outcomes.
Calcaneal fractures are known to influence patients' quality of life negatively. The type of calcaneal fracture might have a relation with the patient outcome. To inform patients in an early stage on how their calcaneal fracture may affect their lives, knowledge of the fracture characteristics is necessary. This study evaluates the association of type of calcaneal fracture, measurement of conventional radiograph angles, and the Sanders classification with patient-reported outcomes. ⋯ Our study implies that patients with an intra-articular calcaneal fracture into the talar surface have a lower health-related quality of life, will be less satisfied with the outcome of their feet, and have more complications compared to patients with other type of calcaneal fractures. Furthermore, the Sanders classification was not associated with the patient-reported outcomes.

The objective was to assess the ability of the volar locking plate to maintain the radiographic parameters over the time in elderly patients with complex intra-articular distal radius fractures. ⋯ This study found that volar locking plate fixation for displaced intra-articular distal radius fractures in elderly patients was an effective procedure to obtain success functional outcomes. Although reduction loss in volar tilt and radial height occurred within four first months, volar plate was able to maintain fracture stabilization with radiographic parameters within functional range over the time in most patients of these elderly patients.

Fluorodeoxyglucose positron emission tomography (FDG-PET) is a novel method of assessing suspected periprosthetic hip infection. However, a heterogeneity of sensitivity and specificity using different diagnostic criteria across clinical studies has been published. The objective of this study is to evaluate the various diagnostic criteria using FDG-PET in diagnosing periprosthetic hip infection. ⋯ Our results demonstrated that the accuracy of FDG-PET is highly dependent of the diagnostic criteria used for periprosthetic hip infection. Only an acceptable diagnostic accuracy (sensitivity 81%; specificity 94%) was found when increased FDG uptake along the femoral bone-prosthesis-interface was considered positive for infection.

Periprosthetic femoral fracture as cause of early revision after short stem hip arthroplasty-a multicentric analysis.
The objective of this study was to analyze the prevalence and causes of early re-operation after hip replacement surgery using short bone-preserving stems in a large multicentre series. Specifically, we evaluated the clinical features of periprosthetic fractures occurring around short stems. ⋯ Periprosthetic femoral fracture was the major reason for re-operation after hip replacement surgery using short bone-preserving stems accounting for 50% (8/16) of re-operations two years post-operatively, but did not seem to deteriorate survivorship of implanted prostheses.
