Late post-arthroscopy hip instability. Diagnosis, treatment, and 5-year follow-up: A case report.

Introduction: Hip instability following arthroscopy is a rare complication with a clinical spectrum ranging from gross dislocation (macro-instability) to micro-instability, characterized by pain and limitation for daily activities. Therefore, it should be considered as a potential differential diagnosis in patients experiencing persistent pain after hip arthroscopy.

Case Presentation: A 41-year-old male presented with a history of anterior hip dislocation and macro-instability symptoms three years post-hip arthroscopy.

Results of the transition from posterolateral to anterior minimally invasive approach for total hip arthroplasty.

Background: The anterior minimally invasive (AMI) approach reduces soft tissue damage, risk of dislocation and enhances recovery, but it is associated with certain complications. The aim of this study is to compare the outcomes of patients who underwent total hip arthroplasty (THA) through posterolateral (PL) and AMI approaches performed by the same surgeon, in order to determine the learning curve associated with this new approach.

Methods: This retrospective cohort study included patients who underwent THA via PL and AMI approach between 2017 and 2022, with a minimum follow-up of 1 year.

Bilateral asymmetric traumatic hip dislocation associated with epiphysiolysis of the femoral head in an adolescent patient.

Background: Bilateral asymmetric hip dislocation is uncommon in childhood, even more when associated with epiphyseal slippage, leading to catastrophic complications of the affected joints, requiring additional surgical interventions, and increasing patient morbidity. In this article, we present the case of a 15 years-old patient with a post-traumatic bilateral hip dislocation with epiphyseal slippage, initially managed with open reduction and fixation, with subsequent need of total hip arthroplasty. Afterward, the patient presented satisfactory outcomes.

How Does Preoperative Anemia Impact Clinical Outcomes Following Primary Total Hip Arthroplasty?: Experience From Colombia.

Background: Anemia is a common condition and a known risk factor for complications after primary total hip arthroplasty. Few studies have evaluated this topic in Latin American countries where this problem can be more important. The purpose of this study was to determine the role of preoperative anemia in 30-day complications after primary total hip arthroplasty.

Body mass index and knee arthroplasty.

Objective: this study aims to evaluate the relationship between body mass index (BMI), age at which knee joint arthroplasty is performed and complications. The hypothesis is that the higher the BMI, the greater likelihood that the patient will require surgery at an earlier age.Methods: this is a cohort study with all patients who underwent a primary knee arthroplasty, between August 2013 and February 2019, in a tertiary level university hospital.

Prospective quality of life assessment after hip and knee arthroplasty: short- and mid-term follow-up results.

Background: Hip and knee arthroplasty aims to restore the joint function and to improve health-related quality of life (HRQoL) in patients with articular damage. It is important to quantify the HRQoL improvement and when this is achieved. The Oxford knee score and the Oxford hip score were developed to evaluate patients after knee and hip arthroplasty.
