Readmissions after elective orthopedic surgery in a comprehensive co-management care system-a retrospective analysis.

Background: No surgical intervention is without risk. Readmissions and reoperations after elective orthopedic surgery are common and are also stressful for the patient. It has been shown that a comprehensive ortho-medical co-management model decreases readmission rates in older patients suffering from hip fracture; but it is still unclear if this also applies to elective orthopedic surgery.

Prolonged antibiotic prophylaxis use in elective orthopaedic surgery - a cross-sectional analysis.

Purpose: Surgical antibiotic prophylaxis (SAP) prevents surgical site infections (SSI). In orthopaedic surgery, the use of prolonged SAP (PSAP) has been reported in daily routine, despite guidelines advising against it. Therefore, we asked: What is the proportion of PSAP use, defined as administration of SAP ≥24 h after elective orthopaedic surgery? Are there patient- and surgery-related predictors of PSAP use?

Methods: This cross-sectional analysis investigated 1292 patients who underwent elective orthopaedic surgery including total joint arthroplasties at one Swiss centre between 2015 and 2017.

Preoperative decolonization and periprosthetic joint infections-A randomized controlled trial with 2-year follow-up.

Preoperative decolonization, especially of Staphylococcus aureus carriers, has been proposed to reduce periprosthetic joint infections (PJI), but the evidence-based consensus is still lacking and data on long-term outcomes is scarce. In a previous randomized, single-blinded trial, decolonization produced no significant reduction of surgical site infections in overall elective orthopedic surgery at 3-month follow-up. A 2-year follow-up was then performed to specifically detect the impact of decolonization on delayed-onset PJI (3-24 months after surgery).

The Hip Sports Activity Scale (HSAS) for patients with femoroacetabular impingement.

Purpose: To develop and validate a sports activity scale for patients with a diagnosis of femoroacetabular impingement (FAI).


Methods: A nine level Hip Sports Activity Scale (HSAS) was constructed both in German and English languages. Fifty-nine consecutive patients undergoing surgical treatment for FAI at two centers in Switzerland and in the US completed a questionnaire set consisting of the HSAS, the University of California at Los Angeles (UCLA) activity scale and different hip joint-specific and generic outcome tools.

MR arthrography of the hip: diagnostic performance of a dedicated water-excitation 3D double-echo steady-state sequence to detect cartilage lesions.

Objective: The objective of our study was to compare the diagnostic performance of a dedicated cartilage MR sequence (water-excitation 3D double-echo steady-state) with a standard MR sequence (T1-weighted spin-echo) in detecting articular cartilage lesions of the hip after intraarticular injection of gadopentetate dimeglumine.

Materials And Methods: In 50 MR arthrograms of the hip joint obtained in 47 consecutive patients, a sagittal 3D double-echo steady-state sequence (TR/TE, 24/6.5; flip angle, 25 degrees ) was compared with a sagittal T1-weighted spin-echo sequence (350/14).

An animal model for interface tissue formation in cemented hip replacements.

Objective: To create a model in sheep for investigation of early changes related to the formation of an interface membrane in hip prosthesis.

Study Design: Experimental study.

Animals: Twenty-four female adult Swiss Alpine sheep.
