The roof step cut: A novel technique for bony reconstruction of acetabular roof deficiency during total hip replacement.

Objectives: This study aims to present a new technique, the roof step cut (RSC), for acetabular augmentation of hip dysplasia.

Patients And Methods: Between December 2008 and March 2020, we applied the RSC technique in a total of 48 hips of 41 patients (2 males, 39 females; mean age: 50.1±9.

Knee Osteoarthritis Pain Management with an Innovative High and Low Molecular Weight Hyaluronic Acid Formulation (HA-HL): A Randomized Clinical Trial.

Introduction: The objective of this study was to compare a single intra-articular injection of an innovative high and low molecular weight hyaluronic acid formulation (HA-HL) versus placebo in treating moderate-to-severe symptomatic knee osteoarthritis.

Methods: Subjects with primary osteoarthritis knee pain (Kellgren and Lawrence grade 2-3) were randomly assigned to intra-articular HA-HL or placebo in a prospective, double-blind, 24-week study. The primary outcome variable was change from screening to week 24 of a Visual Analogue Scale (VAS) pain score.

The biological and biomechanical comparison of two bulk bone graft techniques used in case of dysplastic acetabulum.

Background: The incorporation of bulk bone grafts in the replacement of dysplastic acetabulum is determined by the biological environment of the recipient site, the size of the contact surface, and the stability of the osteosynthesis used. Based on these, the present study compares the Harris acetabular plasty used routinely by us with the Radojević L-shaped graft technique.

Methods: For our measurements, we used 20 hemi-pelvises removed from 10 cadavers.
