Functional outcome improvement and surgical time reduction in a single-surgeon consecutive case series of hip arthroscopy for femoroacetabular impingement: A minimum 5 years follow-up study.

Purpose: The learning curve of a single surgeon performing hip arthroscopy is reported to be steep, but, to date, the inflection point after which procedures are more successful is still unknown. The aim of this study was to design a learning curve focused on clinical outcomes, complications and revision/conversion rates.

Methods: Seventy-one hip arthroscopies performed for femoroacetabular impingement (FAI) by a single surgeon, with a minimum follow-up of 5 years, were considered.

Undiagnosed Periprosthetic Infections in First-Time Aseptic Revision Hip Arthroplasties.

: Unexpected infections diagnosed after intraoperative cultures in aseptic revision hip arthroplasties are infrequent, but the features and outcomes of culture-positive cases are still poorly understood. A single-center retrospective study was conducted to assess the following: (1) the incidence, (2) the profile of the cases, and (3) the outcomes of the revision hips performed for presumed aseptic reasons that became septic after intraoperative cultures. Instances of first-time aseptic revision hips (a retrospective cohort study) in the hospital database were reviewed.

The Effectiveness of Ultrasound-Guided Infiltrations Combined with Early Rehabilitation in the Management of Low Back Pain: A Retrospective Observational Study.

Low back pain is a prevalent condition affecting 60-85% of individuals during their lifetime. Despite various proposed mechanisms, the etiology of low back pain remains unclear. This study aims to evaluate the effectiveness of combining ultrasound-guided infiltrations with early rehabilitation in reducing pain and improving functional limitations in patients with chronic nonspecific low back pain.

Modern cementless acetabular cups in total hip arthroplasty performed for primary osteoarthritis: a comparative registry study.

Introduction: Comparative studies evaluating the different material and surface finishing of acetabular components in total hip arthroplasty (THA) are lacking. Using a regional arthroplasty registry, the survival rates and the hazard ratios of different cups in THA performed for primary osteoarthritis were assessed, using endpoints: (1) every cup failure, (2) cup aseptic loosening, (3) periprosthetic infection.

Materials And Methods: The inclusion criteria were: residing patients, THA for primary osteoarthritis, Delta-on-Delta bearings, head sizes 32 mm and 36 mm.
