Analysis of carpal kinematics after radiolunate and radioscapholunate arthrodesis shows good preservation of midcarpal joint congruity and motion. However, no biomechanical data exist on carpal kinematics after radiolunate arthrodesis in the wrist. Purpose of this study was to examine the individual motion of scaphoid, capitate and triquetrum after simulated radiolunate arthrodesis. ⋯ The presented data conform with the good clinical results obtained after radiolunate arthrodesis in the rheumatoid wrist and furthermore, encourage its use in the posttraumatic wrist.

Repair of retropatellar cartilage defects in the knee with microfracture and a cell-free polymer-based implant.
To analyze magnetic resonance imaging (MRI) at 3T and the clinical outcome in a short-term pilot study after treatment of retropatellar cartilage defects with microfracturing and subsequent covering with the cell-free chondrotissue(®) polyglycolic acid-hyaluronan implant. ⋯ IV, case series.

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.

Randomized Controlled TrialDoes intraoperative application of leukocyte-poor platelet-rich plasma during arthroscopy for knee degeneration affect postoperative pain, function and quality of life? A 12-month randomized controlled double-blind trial.
We aimed to identify the effects of intraoperative applied leukocyte-poor platelet-rich plasma (LP-PRP) during knee arthroscopy for degenerative lesions involving pain, function and quality of life. ⋯ NCT02189408.
