Best practices on patient education materials in hip surgery based on learnings from major hip centers and societies.

Patient education is important as it gives patients a better understanding of the risks and benefits of medical and surgical interventions. Developing communication technologies have completely changed and enhanced patient access to medical information. The aim of this study was to evaluate available patient education materials (PEMs) regarding hip surgery on the websites of major hip societies and centers.

Stepwise Safe Access in Hip Arthroscopy in the Supine Position: Tips and Pearls From A to Z.

Hip arthroscopy is rapidly growing as a treatment with good outcomes for pathologic conditions such as femoroacetabular impingement syndrome and labral tears. At the same time, it is one of the most technically challenging and demanding procedures in orthopaedics with a technically demanding skill. The first challenge is to safely access the joint, which requires accurate anatomical knowledge, a strong sense of spatial orientation, and repeated practice.

Binary Tönnis classification: simplified modification demonstrates better inter- and intra-observer reliability as well as agreement in surgical management of hip pathology.

Background: The traditional Tönnis Classification System has inherent drawbacks as it is vulnerable to the subjectivity of a four-grade system. A two-grade classification could potentially be more reliable. The purpose of this study is to (1) compare the inter-observer and intra-observer reliability of the traditional Tönnis Classification System and a simplified Binary Tönnis Classification System for hip osteoarthritis and to (2) evaluate the clinical applicability of both systems.

Purpose: To report and analyze minimum 2-year patient-reported outcomes (PROs) from patients who underwent open GM repair in the setting of a full-thickness tear with or without concomitant hip arthroscopy through use of contemporary tendon repair techniques.

Robotic Arm-assisted Total Hip Arthroplasty is More Cost-Effective Than Manual Total Hip Arthroplasty: A Markov Model Analysis.

Background: Total hip arthroplasty (THA) is the benchmark surgical treatment of advanced and symptomatic hip osteoarthritis. Preliminary evidence suggests that the robotic arm-assisted (RAA) technology yields more accurate and reproducible acetabular cup placement, which may improve survival rate and clinical results, but economic considerations are less well-defined. The purpose of this study was to compare the cost effectiveness of the RAA THA with manual THA (mTHA) modalities, considering direct medical costs and utilities from a payer's perspective.
