Multicenter Study
What parameters affect knee function in patients with untreated cartilage defects: baseline data from the German Cartilage Registry.
To evaluate the factors influencing the baseline Knee Injury and Osteoarthritis Outcome Score (KOOS) in patients with knee cartilage defects and planned cartilage repair surgery and to provide baseline KOOS data from a large patient population. ⋯ Several factors influencing baseline KOOS data in patients with knee cartilage defects assigned for cartilage repair surgery could be detected. Their individual influence in the multivariate linear regression model was not very strong. Baseline data according to these criteria is presented in this paper.

Multicenter Study Comparative Study
Multicentre comparative study of Z-shape elevating-pulling reduction and skull traction reduction for treatment of lower cervical locked facets.
The aim of this study was to assess the clinical efficacy and safety of Z-shape elevating-pulling reduction as compared to that of conventional skull traction in the treatment of lower cervical locked facet. ⋯ Halo vest-assisted Z-shape elevating-pulling reduction appears to be a simple, safe, and effective technique for pre-operative reduction of lower cervical locked facets.

Wound complications after open reduction and internal fixation of tibial plateau fractures in the elderly: a multicentre study.
The incidence of wound complications after open reduction with internal fixation (ORIF) of tibial plateau fractures in young patients has been reported to range from approximately 5 to 15%. Reports on wound complication rates in the elderly patients are limited. This study investigates the incidence of post-operative wound complications in elderly patients undergoing ORIF of their tibial plateau fractures. ⋯ The overall infection rates in elderly patients undergoing ORIF for tibial plateau fractures is in a similar range to published data on younger patient populations. In particular, elderly patients without significant co-morbidities seem to be appropriate candidates for ORIF of their tibial plateau fractures. However, elderly patients with significant co-morbidities must be considered as high risk and alternative treatment options, such as nonoperative treatment or less invasive surgical options, should be explored in these patients.

Multicenter Study
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.

Multicenter Study
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.
