Dobutamine stress echocardiography in patients with moderate coronary artery disease detected by coronary computed tomography angiography could reduce the rate of unnecessary coronary angiography.

Aims: To test the hypothesis that dobutamine stress echocardiography (DSE) reduces the rate of unnecessary invasive coronary angiography (CA) in patients with chronic stable coronary artery disease (CAD) and moderate to severe stenosis detected by coronary computed tomography angiography (CCTA).

Methods: This study included 49 consecutive, symptomatic CAD patients with coronary lesions greater than 50% detected by CCTA who underwent all DSE and a CA with pressure wire evaluation and FFR measurement. The DSE operators was aware of the CCTA results, but invasive physicians were blinded to DSE results.

Reconstruction of a Neglected Tibial Plateau Fracture Malunion with an Open-Book Osteotomy: A Case Report.

Case: Surgical management of tibial plateau fractures can be challenging, and complications can be devastating. We report the case of a lateral tibial plateau fracture malunion with an associated intra-articular depression, which we treated with an open-book osteotomy, obviating the need for an early corrective osteotomy or knee arthroplasty.

Conclusion: A tibial plateau fracture malunion can be reconstructed.

Open Versus Arthroscopic Mosaicplasty of the Knee: A Cadaveric Assessment of Accuracy of Graft Placement Using Navigation.

Purpose: The purpose of this study was to compare an open freehand mosaicplasty technique with an arthroscopic technique for the treatment of osteochondral lesions by measuring the instrument deviation, quantifying this deviation, and providing numerical information on the difference in the outcomes of these techniques.

Methods: Four cadaveric knees were used. Reference markers were attached to the femur, tibia, and donor/recipient site guides.
