Multicenter StudyAccuracy of a novel extramedullary femoral alignment guide system in primary total knee arthroplasty.
We aimed to assess the accuracy of a new extramedullary guide system for achieving appropriate femoral component alignment in total knee arthroplasty (TKA) and to determine whether it differed between patients operated on by different surgeons. ⋯ This study shows that the S-guide is reliable for use in TKA.

Multicenter StudyGraft tensioning practices in anterior cruciate ligament reconstruction amongst orthopaedic surgeons in Australia: a national survey.
The application of graft tension during anterior cruciate ligament reconstruction is considered an important feature of ACLR. However, wide variation exists in relation to graft tensioning practice limiting the ability to determine the best approach. Thus, the primary aim of this study was to describe current clinical practice amongst Australian orthopaedic surgeons with respect to graft tensioning and explore influencing factors. ⋯ Tensioning practices appear to consist of three main approaches, (1) manual tension using a sustained maximum one-handed pull, with tension estimated as 41-60 N, applied near full extension, (2) tensioning device, mean tension of 81.85 N, at 30° knee flexion, (3) individual approach based on size and viscoelastic properties of the graft, patient anthropometry, contralateral comparison to the other knee and age of the patient.

Multicenter StudyThe compliance with and knowledge about radiation protection in operating room personnel: a cross-sectional study with a questionnaire.
Radiation protection is becoming more important with an ongoing increase in radiation exposure due to the use of X-rays in minimally invasive procedures in orthopaedic and trauma surgeries. However, sufficient education in medical physics and radiation protection can often be improved. ⋯ Cross-sectional study with a questionnaire.

Randomized Controlled Trial Multicenter StudyTopical and intravenous tranexamic acid reduce blood loss compared to routine hemostasis in total knee arthroplasty: a multicenter, randomized, controlled trial.
Tranexamic acid (TXA) is becoming widely used in orthopedic surgery to reduce blood loss and transfusion requirements, but consensus is lacking regarding the optimal route and dose of administration. The aim of this study was to compare the efficacy and safety of topical and intravenous routes of TXA with routine hemostasis in patients undergoing primary total knee arthroplasty (TKA). ⋯ I.

Multicenter StudyAcetabular fracture assessment in four different pelvic trauma centers: have the Judet views become superfluous?
The present study was designed to examine whether oblique radiographs (Judet views) in addition to 2D and 3D CT scans improved the intra- and interobserver reliability when assessing acetabular fractures. ⋯ The moderate agreement found for the Letournel classification is to be expected given the complexity of the classification. The addition of oblique radiographs to the image sets does not seem to improve the reliability and thus its routine use for classification and decision making may be debated.
