A novel handheld robotic-assisted system for unicompartmental knee arthroplasty: surgical technique and early survivorship.

Technology, including robotics, has been developed for use in unicompartmental knee arthroplasty (UKA) to improve accuracy and precision of bone preparation, implant positioning, and soft tissue balance. The NAVIO™ System (Smith and Nephew, Pittsburgh, PA, United States) is a handheld robotic system that assists surgeons in planning implant positioning based on an individual patient\u27s anatomy and then preparing the bone surface to accurately achieve the plan. The surgical technique is presented herein. In addition, initial results are presented for 128 patients (mean age 64.7 years; 57.8% male) undergoing UKA with NAVIO. After a mean of follow-up period of 2.3 years, overall survivorship of the knee implant was 99.2% (95% confidence interval 94.6-99.9%). There was one revision encountered during the study, which was due to persistent soft tissue pain, without evidence of loosening, subsidence, malposition or infection. These initial results suggest a greater survivorship than achieved in the same follow-up time intervals in national registries and cohort studies, though further follow-up is needed to confirm whether this difference is maintained at longer durations

Unequal relationships in high and low power distance societies: a comparative study of tutor - student role relations in Britain and China

This study investigated people's conceptions of an unequal role relationship in two different types of society: a high power distance society and a low power distance society. The study focuses on the role relationship of tutor and student. British and Chinese tutors and postgraduate students completed a questionnaire that probed their conceptions of degrees of power differential and social distance/closeness in this role relationship. ANOVA results yielded a significant nationality effect for both aspects. Chinese respondents judged the relationship to be closer and to have a greater power differential than did British respondents. Written comments on the questionnaire and interviews with 9 Chinese academics who had experienced both British and Chinese academic environments supported the statistical findings and indicated that there are fundamental ideological differences associated with the differing conceptions. The results are discussed in relation to Western and Asian concepts of leadership and differing perspectives on the compatibility/incompatibility of power and distance/closeness

Editorial: A Commentary on the Assessment and Analysis of “Culture-Content” in Basic Psychology Texts

This commentary focuses on one basic question: “How and to what extent do beginning university students in North America (United States as well as Canada) learn about culture’s influence on behavior via introductory psychology texts that are almost always published in the U.S.?” An overarching question permeates the article: What objective methods have been used to find and evaluate the cultural content of beginning psychology texts? These questions are considered important in the teaching of psychology at the basic level and can influence the authors of texts that are central in psychology curricula in general and teaching cross-cultural psychology in particular. In this unit, the earlier article by Lonner and Murdock (2012) and the recently uploaded article by Scott and Safdar (2016) focus on the cultural content of two types of basic texts in psychology. Respectively, they are the workhorse introductory text (IPT) and those that introduce social psychology (SPT). The main purpose of these two studies and seminal writings (Lonner, 1989; Rumple, 1988) was to assess and analyze the extent to which such texts in these areas contain information on culture and its proxies such as ethnicity and diversity
