Association of Preoperative Walking Speed With 1-Year Outcomes After Hip Arthroscopy for Femoroacetabular Impingement Syndrome.

Background: Previous studies have identified demographic, radiographic, and intraoperative predictors of outcomes after hip arthroscopy for femoroacetabular impingement syndrome, yet few studies have identified whether preoperative gait metrics can predict outcomes.

Hypothesis: Increased preoperative step count, walking speed, step length, and gait symmetry will be associated with better outcomes after surgery.

Study Design: Retrospective cohort study.

The Continuous Fragility Index of Statistically Significant Findings in Studies Based on High Levels of Evidence Comparing Interventions for Femoroacetabular Impingement Syndrome.

Background: Critical analysis of studies with high level of evidence has relied on the significance set by the reported values. However, this strategy steers readers toward categorical interpretation of the data; therefore, a more comprehensive approach of data analysis is warranted. The continuous fragility index (CFI) allows for frailty interpretation of any given study's continuous outcome results.

Basic Hip Arthroscopy Part 2: Central Compartment Arthroscopy (Interportal Capsulotomy, Acetabuloplasty, and Labral Repair).

Over the past decade, hip-preservation strategies have gained momentum, resulting in a notable increase in the use of hip arthroscopy for diagnostic and therapeutic interventions in hip-related pathology. In this 3-part series, the authors will aim to comprehensively review the fundamentals of hip arthroscopy in the setting of femoroacetabular impingement. This Technical Note will thoroughly review the senior authors' approach to managing the central compartment of the hip in the context of femoroacetabular impingement.

Basic Hip Arthroscopy Part 1: Patient Positioning and Portal Placement.

Over the past decade, hip-preservation strategies have gained momentum, resulting in a notable increase in the use of hip arthroscopy for diagnostic and therapeutic interventions in hip-related pathology. In this 3-part series, the authors will aim to comprehensively review the fundamentals of hip arthroscopy in the setting of femoroacetabular impingement. While considering the advantages and disadvantages of post versus postless hip arthroscopy, this Technical Note will review the preferred patient and portal positioning approach used by the senior authors.

Basic Hip Arthroscopy Part 3: Peripheral-Compartment Arthroscopy (T-Capsulotomy, Femoroplasty, and Capsular Closure).

Over the past decade, hip preservation strategies have gained momentum, resulting in a notable increase in the use of hip arthroscopy for diagnostic and therapeutic interventions for hip-related pathology. In this 3-part series, we aim to comprehensively review the fundamentals of hip arthroscopy in the setting of femoroacetabular impingement. This Technical Note will thoroughly review the senior authors' approach to managing the peripheral compartment of the hip in the context of femoroacetabular impingement.
