Background: Hip osteoarthritis patients display higher levels of fatty infiltration (FI) in the gluteus minimus (GM) compared to other hip muscles. We investigated specific histological factors such as fiber type composition and collagen deposition, and functional outcomes like muscle strength and activation associated with FI in these patients.

Methods: In twelve men (67 ± 6 y) undergoing total hip replacement (THR), hip and knee muscle strength and activation (electromyography, EMG) were assessed bilaterally.

Article Synopsis
  • Systemic antibiotic prophylaxis (SAP) is crucial in preventing infections after joint surgeries, but there's disagreement on how long and how much should be given.
  • Recent studies indicate that extending SAP for less than 24 hours after surgery could lead to better outcomes than a single dose.
  • Researchers advocate for more thorough recording of SAP practices in national registries to improve understanding and guidance on optimal antibiotic use in arthroplasty.

Background: Although the direct anterior approach (DAA) represents an intermuscular and internervous approach to total hip arthroplasty (THA), it did not reach global acceptance until its adoption by large teaching centers. Today, >50% of primary THA procedures in Switzerland are performed via the DAA. Besides being truly minimally invasive, a key advantage of the DAA is the inherent stability that it provides.

Introduction: Aseptic femoral stem loosening is among the most common causes for revision in total hip arthroplasty (THA). We describe a simple clinical test that triggers pain in the proximal femur in patients with a loose stem. A previously described passive rotation test was associated with a poor sensitivity.

Aims: The purpose of this study was to evaluate the mid-term outcomes of autologous matrix-induced chondrogenesis (AMIC) for the treatment of larger cartilage lesions and deformity correction in hips suffering from symptomatic femoroacetabular impingement (FAI).

Methods: This single-centre study focused on a cohort of 24 patients with cam- or pincer-type FAI, full-thickness femoral or acetabular chondral lesions, or osteochondral lesions ≥ 2 cm, who underwent surgical hip dislocation for FAI correction in combination with AMIC between March 2009 and February 2016. Baseline data were retrospectively obtained from patient files.
