Defining Thresholds for the Patient Acceptable Symptom State for the IKDC Subjective Knee Form and KOOS for Patients Who Underwent ACL Reconstruction

Abstract: Background:A clinically meaningful change in patient-reported outcome (PRO) may not be associated with an acceptable state that corresponds to “feeling well,” also known as the patient acceptable symptom state (PASS). The PASS thresholds for the International Knee Documentation Committee Subjective Knee Form (IKDC-SKF) and the Knee injury and Osteoarthritis Outcome Score (KOOS) have not been determined for individuals after anterior cruciate ligament (ACL) reconstruction.Purpose:To determine the PASS thresholds for the IKDC-SKF and KOOS in individuals at 1 to 5 years after ACL reconstruction.Study Design:Cohort study (diagnosis): Level of evidence, 2.Methods:Individuals 1 to 5 years after primary ACL reconstruction completed a survey that included the IKDC-SKF and KOOS. All subjects assessed satisfaction with their current state by answering the question, “Taking into account all the activity you have during your daily life, your level of pain, and also your activity limitations and participation restrict...

Secondary alveolar bone grafting: the dilemma of donor site selection and morbidity.

Abstract: Fresh autogenous cancellous bone is ideal for secondary alveolar cleft bone grafting because it supplies living, immunocompatible bony cells that integrate fully with the maxilla and are essential for osteogenesis Recent animal studies have shown that the dynamics of cancellous inlay bone grafts are different from those of cortical onlay bone grafts, and they refute the assumption that membranous bone grafts are superior to endochondral bone grafts because of their embryological origin These studies prove that inlay endochondral cancellous specimens have a higher percentage increase in actual bony volume than cortical membranous and cortical endochondral inlay bone grafts There are various donor sites for secondary alveolar cleft bone grafts Currently the main sites for autogenous cancellous bone are iliac crest, calvarium, mandibular symphysis, and tibia Some authors have suggested that the iliac crest donor site causes an unacceptably high degree of postoperative morbidity, but it is still the first choice for secondary alveolar cleft bone grafts and should not be rejected solely because of such concerns Recombinant human bone morphogenetic protein-2 (rhBMP-2) is now an attractive bony substitute that promotes the differentiation of pluripotential cells into bone-forming cells that lay down new host bone in the site of the defect Much more research and development are necessary to find a suitable carrier for rhBMP-2, and to study the properties of newly formed bone that it has induced before it can be a substitute for autogenous bone

Shaping ability of Profile rotary nickel‐titanium instruments with ISO sized tips in simulated root canals: Part 1

Abstract: The aim of this study was to determine the shaping ability of ProFile 0.04 taper rotary nickel-titanium instruments with ISO sized tips in simulated canals. A total of 40 simulated root canal made up of four different shapes in terms of angle and position of curvature were prepared by ProFile instruments using the 'crown down' approach recommended by the manufacturer. Part 1 of this two-part report describes the efficacy of the instruments in terms of preparation time, instrument failure, canal blockages, loss of canal length and three-dimensional canal form. The time necessary for canal preparation was on average 5.2 min and was not influenced significantly by canal shape. Three instrument fractures occurred and a further 3 instruments deformed; size 35 instruments failed the most (4) followed by size 30 (2), four of the failures occurred in canals with 40 degrees curves. None of the canals became blocked with debris and change in working distance was minimal. Intra-canal impressions of canal form demonstrated that most canals had apical stops and smooth canal walls whereas all canals had good flow and taper. Under the conditions of this study, ProFile 0.04 taper rotary nickel-titanium instruments with ISO sized tips prepared simulated canals rapidly and created good three-dimensional form.
