Mid-term clinical radiological results of the constrained condylar knee prosthesis in total knee revision.

Introduction: The aim of the present study is to analyze the clinical-radiological outcomes of patients undergoing knee prosthesis revision surgery using constrained condylar prosthesis (LCCK; Zimmer-Biomet).

Material And Methods: Retrospective study of 89 patients operated on between the years 2008 and 2020 with a minimum of 2 years of follow-up. Clinical outcomes were evaluated using the WOMAC Index score and KOOS scales.

Gluteus Medius Repair using a Gluteus Maximus Flap Augmented with Synthetic Polyethylene Mesh: Surgical Technique and Case Series.

Introduction: Gluteus medius tendon tears may not be feasible for direct repair when significant retraction or fatty degeneration is present. Several augmentation techniques have been reported for challenging cases. We describe a novel technique using a transfer of the anterior portion of the gluteus maximus combined with synthetic mesh to reinforce the direct suture of the gluteus medius.

Thirty-day mortality in patients with a proximal femur fracture during the COVID-19 pandemic in Biscay (Basque Country).

Objectives: Compare 30-day mortality rate following a proximal femur fracture (PFF) and SARS-CoV-2 infection versus a PFF and no SARS-CoV-2 infection.

Design: Retrospective comparative study.

Setting: Three university hospitals in Biscay province (Basque Country, Spain).

High mortality rate following periprosthetic femoral fractures after total hip arthroplasty. A multicenter retrospective study.

Background: The main objective of this study was to evaluate the morbidity and mortality following periprosthetic femoral fractures (PFFs) after total hip arthroplasty. The secondary objectives were to explore risk factors for mortality and compare outcomes by method of treatment.

Methods: A multicenter retrospective study was conducted (2016-2017) of all PFFs after total hip arthroplasty.

Cementation of a dual-mobility cup into a well-fixed cementless shell in patients with high risk of dislocation undergoing revision total hip arthroplasty.

Background: Cementation of polyethylene liners into well-fixed cementless metal shells has become an option during revision total hip arthroplasty (THA). We report the results of cementing a dual-mobility (DM) component into a stable acetabular shell in high-risk patients undergoing revision THA.

Methods: A single-centre series of 10 patients undergoing revision THA with a DM cup cemented into an existing well-fixed shell between 2012 and 2016 were retrospectively reviewed.

DAIR (Debridement, Antibiotics and Implant Retention) less effective in hematogenous total knee arthroplasty infections.

Background: Debridement and irrigation with prosthetic retention followed by antibiotic therapy (DAIR) is one of the treatments of choice in acute infections after a total knee arthroplasty. However, the success rate varies widely in the literature, depending on several factors such as comorbidities of the patient, duration of infection, and microorganisms involved. The goal of this study was to assess the outcomes of this therapeutic option and to identify possible predictors of the result.

Medium-term outcomes of the S-ROM modular femoral stem in revision hip replacement.

Introduction: The objective of this study was to analyse results achieved with the S-ROM modular stem in revision surgery.

Materials And Methods: A retrospective observational study was conducted from 2007 to 2015 including 51 patients who had a follow-up of ≥ 2 years and complete medical history. The mean age was 66.

Prognostic factors after a traumatic hip dislocation. A long-term retrospective study.

Introduction: Traumatic hip dislocations can have devastating complications such as osteoarthritis or osteonecrosis. The aim of this study was to identify the variables and prognostic factors associated with clinical and radiological outcome after a traumatic hip dislocation at long-term follow-up.

Material And Methods: A review was performed of all dislocations and fracture-dislocations of the hip from January 1999 to December 2012.

Does the tibia component design affect the need for offset stems in revision total knee arthroplasty?

Introduction: The stem/keel location varies between anatomic and symmetric revision tibial baseplates. The current study investigates the impact of an anatomic versus symmetric stem location on the need for offset couplers in revision total knee arthroplasty.

Materials And Methods: Hip to ankle standing radiographs and lateral radiographs of 75 patients were analyzed using digital templating software.

Cauda equina syndrome secondary to lumbar disc herniation: Surgical delay and its relationship with prognosis.

Objective: To determine whether surgical treatment delayed for more than 48 hours in patients with cauda equina syndrome (CES) influenced the clinical outcome.

Material And Methods: A retrospective study of 18 patients treated in our hospital from March 2000 to January 2012, after presenting with CES. The pre- and post-operative clinical status was determined: existence of back pain and/or sciatica, sensory disturbance in the perineum, sensory and motor deficits in the lower extremities, and the degree of sphincter incontinence (complete or incomplete CES).

Late sciatic nerve axonotmesis following acetabular reconstruction plate.

Sciatic nerve injuries associated with acetabular fractures can be post-traumatic, perioperative or postoperative. Late postoperative injury is very uncommon and can be due to heterotopic ossifications, muscular scarring, or implant migration. A case is presented of a patient with a previous transverse acetabular fracture treated with a reconstruction plate for the posterior column.
