          Introduction: Total hip replacement provides mostly fair functional and clinical results. Many factors play an essential role in hip stability and long-term outcomes. Surgical positioning remains fundamental for obtaining accurate implant fit and prevent hip dislocation or impingement. Different categories of robotic assistance have been established throughout the previous years and all of the technologies target accuracy and reliability to reduce complications, and enhance clinical outcomes. Materials and methods: An overview is proposed over the principles of robotic assistance in hip arthroplasty surgery. Accuracy, reliability, management of the bone stock, clinical outcomes, constraints and limits of this technology are reported, based on recent literature. Results: Potential advantages regarding pre-operative planning accuracy, cup positioning, maintenance of the center of rotation, preservation of an adequate bone stock nay clinical short- and mid-term outcomes are balanced with some reported disadvantages and limits like hip anatomical specificity, cost-effectiveness, engineering dependence. Discussion: The use of robotic-assisted THA presents clear and evident benefits related to accurate implant positioning and maintenance of a minimal bone while allowing. For some authors, an early improvement in functional results and patient’s recovery. This technology demonstrated a shorter surgical time and a short learning curve required to optimize its use and this technology presents promising outcomes and results and potential use in routine clinical application but its limitation of use is still present especially the cost of the robot, the need for the presence of an engineer during the surgery, its availability of use in all hospitals as well as the difficulty presented in dysplastic or dysmorphic hip joints.

            The definition and measurement of acetabular orientation.

            The orientation of an acetabulum or an acetabular prosthesis may be described by its inclination and anteversion. Orientation can be assessed anatomically, radiographically, and by direct observation at operation. The angles of inclination and anteversion determined by these three methods differ because they have different spatial arrangements. There are therefore three distinct definitions of inclination and anteversion. This paper analyses the differences between the definitions and provides nomograms to convert from one to another. It is recommended that the operative definitions be used to describe the orientation of prostheses and that the anatomical definitions be used for dysplastic acetabula.

              The "forgotten joint" as the ultimate goal in joint arthroplasty: validation of a new patient-reported outcome measure.

              With improving patient outcome after joint arthroplasty, new assessment tools with increased discriminatory power especially in well-performing patients are desirable. The goal of the present study was to develop and validate a new score ("Forgotten Joint Score," or FJS) introducing a new aspect of patient-reported outcome: the patient's ability to forget the artificial joint in everyday life. After a pilot study, the FJS was validated and showed high internal consistency (Cronbach α = .95). Ceiling effects were considerably lower for the FJS (9.2%) compared with the Western Ontario and McMaster Universities subscales (16.7%-46.7%). Known-group comparisons proved the FJS to be highly discriminative in a validation sample of 243 patients. The FJS not only reflects differences between "good" and "bad" but also between "good," "very good," and "excellent" outcomes. This concise score is appealing for its more adequate measurement range and because it measures the new, promising concept of the "forgotten joint." Copyright © 2012 Elsevier Inc.
