Perioperative experiences of patients with high pain catastrophizing and knee arthroplasty after receiving or not preoperative physiotherapy: Qualitative study.

Background: Among the risk factors studied for persistent pain after total knee arthroplasty (TKA), pain catastrophizing stands out above the others. In this regard, preoperative interventions based on pain neuroscience education or multimodal physiotherapy have been shown to be effective in reducing pain catastrophizing.

Objectives: The present qualitative study aims to explore the perioperative experiences of high pain catastrophizing participants undergoing total knee arthroplasty surgery.

Intervention to reduce the incidence of surgical site infection in spine surgery.

Background: This study examines the incidence, characteristics, and risk factors of surgical site infections (SSIs) after spine surgery and evaluates the efficacy of a preventive intervention.

Methods: This was a quasi-experimental pretest/posttest study in patients undergoing spinal surgery in an orthopedic surgery department from December 2014 to November 2016. Based on the results of the study, we revised the preventive protocol with modification of wound dressing, staff training, and feedback.

What is the role of bone scintigraphy in the diagnosis of infected joint prostheses?

Aim: To analyse the role played by bone scintigraphy in the diagnosis of infected joint prostheses.

Methods: The study included 77 patients, aged 32-77 years, in whom infection of a joint prosthesis (48 hip, 29 knee) was suspected. In all patients the following examinations were performed consecutively: a two-phase Tc methylene diphosphonate (Tc-MDP) bone scan, a Tc hexamethylproplyene amine oxime (Tc-HMPAO) labelled white blood cell (WBC) scan, and a Tc microcolloid bone marrow (BM) scan.
