Assessment of Medical and Social Risk Factors Before Arthroplasty in Argentina: A Poll of Argentinian Hip and Knee Association (ACARO) Members.

Background: Assessment of risk factors is crucial for lowering complication rates and costs of hip and knee arthroplasty. The objective of this study was to assess if members of the Argentinian Hip and Knee Association (ACARO) are influenced by such risk factors when planning surgery.

Methods: In 2022, a survey was distributed as an electronically based questionnaire to 370 members of the ACARO.

4- to 8-year complication analysis of 2 'partial collum' femoral stems in primary THA.

Objectives: Compare the clinical and radiological outcome of CFP stem with the MiniHip design in a prospective series, with special interest in intraoperative periprosthetic fracture (IPPF).

Methods: We prospectively followed 101 cases treated with the MiniHip stem (Group 1) and 89 with the CFP stem (Group 2) operated between 2010 and 2014. No significant demographic differences were observed between both groups.

THA conversion rate comparing decompression alone, with autologous bone graft or stem cells in osteonecrosis.

Introduction: Core decompression (CD) with or without the addition of autologous bone graft (CDBG) is currently the most widely accepted treatment for hip osteonecrosis in stages of pre-collapse. The use of bone marrow mesenchymal stem cells (CDSC) is emerging as a promising biological alternative. We sought to determine the total hip arthroplasty (THA) conversion rate for patients treated with CD, CDBG or CDSC.

Minimally Invasive Double-Button Fixation of Displaced Lateral Clavicular Fractures in Athletes.

Background: Early union and a rapid return to prior function are the priorities for young athletes with lateral clavicular fractures. Furthermore, it is essential to avoid nonunion in this subgroup of patients, as this is frequently associated with persistent pain, restriction of movement, and loss of strength and endurance of the shoulder.

Purpose: To analyze the time to return to sport, functional outcomes, and complications in a group of athletes with displaced lateral clavicular fractures treated using closed reduction and minimally invasive double-button fixation.

A critical analysis of radiographic factors in patients who develop dislocation after elective primary total hip arthroplasty.

Purpose: In order to diminish total hip arthroplasty (THA) dislocation rate, surgeons strive to achieve adequate component orientation, offset and limb length. In addition, dislocation rate can theoretically be reduced by increasing head diameter and by choosing implants with favorable head-to-neck and cup-to head ratios. We assessed nine radiographic and implant-related parameters associated with an increased risk of dislocation in patients who sustained a dislocation and in those with a stable arthroplasty.
