The CERAB technique is a safe and feasible technique for the treatment of extensive AIOD with good 3-year results regarding patency and clinical improvement.

Axial plane alignment is considered the 'third dimension' in TKA. Correct axial alignment the lower extremity and of prosthetic components is deemed an important prerequisite for a postoperatively stable and painless knee. Identification of and, where appropriate, adjustment for any pre-existing maltorsion deformities is thought to significantly reduce the proportion of patients with residual complaints following TKA. Well-designed and well-conducted clinical studies are required to support our hypotheses.

To report the 1-year outcomes of the prospective Legflow drug-coated balloon (DCB) registry, which evaluated the safety and 12-month efficacy of the Legflow balloon in the treatment of femoropopliteal disease. Methods: The Legflow is a new generation of DCB that has a homogenous, stable surface coating incorporating 0.1-µm paclitaxel particles. From January 2014 to June 2016, 139 patients (mean age 67.1±10.8 years; 109 men) were enrolled at 4 European institutions. Seventy-nine (56.8%) patients had claudication, while 60 (43.2%) had critical limb ischemia (CLI). Mean lesion length (MLL) was 90.0±41.2 mm. Eighty (57.6%) patients were treated for de novo lesions (MLL 83.2±41.2 mm), 29 (20.9%) for postangioplasty restenosis (MLL 81.2±30.9 mm), and 30 (21.6%) for in-stent restenosis (MLL 117.0±39.5 mm). The primary outcome measure was freedom from binary restenosis as determined by a peak systolic velocity ratio ≥2.4 on duplex or >50% stenosis on digital subtraction angiography at 12 months. The secondary outcome was freedom from clinically-driven target lesion revascularization (CD-TLR) at 12 months. Results: Technical success was achieved in all the 139 treated patients. During the hospital stay, 3 CLI patients died of wound-related complications and 3 CLI patients underwent urgent TLR due to early occlusion in 2 and stent thrombosis in 1. At 12 months, 4 additional patients died of cardiac disease unrelated to the procedure. Of the 132 patients available for 1-year follow-up, the primary outcome (freedom from restenosis) was obtained in 107 (81.1%) patients. Freedom from CD-TLR was obtained in 110 (83.3%). Of the 25 late restenoses >50%, only 3 asymptomatic patients did not require TLR. Freedom from CD-TLR was higher in claudicants (87.0%) than in CLI patients (78.2%, p=0.20). In patients treated for in-stent restenosis, freedom from TLR at 1 year was 89.2%. Conclusion: These data suggest that the use of a new generation paclitaxel-coated balloon represents a safe and effective therapeutic strategy for femoropopliteal obstructions in different clinical and anatomical settings. These data will need to be confirmed with longer-term follow-up and in randomized controlled trials.
