Physical functioning before knee arthroplasty is not associated with (standardized) preoperative physiotherapy, but is tied to physical functioning 1-year post-surgery: A prospective cohort study.

Background: and purpose This study investigates whether a (regionally) standardized physiotherapy approach, employing a stepped-care model, can more effectively enhance preoperative physical function in end-stage osteoarthritis (OA) patients undergoing total knee arthroplasty (TKA) or unicompartmental knee arthroplasty (UKA) and improve postoperative outcomes, addressing the current gap in understanding the impact of such interventions.

Methods: This mono-center observational prospective cohort study followed 216 primary UKA or TKA patients for one-year post-surgery. Preoperative physiotherapy, recorded through self-reported questionnaires, included standardization and treatment frequency details.

Mid-term outcomes of acute and delayed total knee arthroplasty following tibial plateau fractures: A matched cohort study.

Introduction: Patients who sustain a tibial plateau fracture (TPF) have a higher risk of receiving total knee arthroplasty (TKA). Rarely, TKA is used as acute treatment for TPFs. This study aimed to compare both acute and delayed TKA following TPF with matched patients undergoing elective TKA for osteoarthritis.

Anxiety and depression prior to total knee arthroplasty are associated with worse pain and subjective function: A prospective comparative study.

Purpose: The aim of this study was to investigate the influence of preoperative anxiety and depression on subjective function, pain and revision rates following total knee arthroplasty (TKA).

Methods: A prospective comparative study was conducted, including 349 patients undergoing TKA surgery between January 2019 and April 2021. Patients completed the Hospital Anxiety and Depression Scale (HADS) questionnaire preoperatively, and a set of Patient-Reported Outcome Measures (PROMs) preoperatively and at 6, 12 and 24 months postoperatively.

The mind matters: Psychological factors influence subjective outcomes following unicompartmental knee arthroplasty-A prospective study.

Purpose: This study aimed to investigate how psychological factors, including pain catastrophizing (PC), anxiety and depression affect preoperative and postoperative subjective outcomes in patients undergoing unicompartmental knee arthroplasty (UKA).

Methods: A prospective comparative study was performed among 150 patients undergoing medial or lateral UKA for isolated unicompartmental osteoarthritis. Patients were categorized based on their preoperative PC and Hospital Anxiety and Depression Scale, stratifying them into groups with PC, anxiety or depression, and those without these psychological factors.

Preoperative Pain Catastrophizing Prior to Total Knee Arthroplasty is Associated With Worse Preoperative Symptoms and More Clinical Improvement: A Prospective Comparative Study.

Background: Total knee arthroplasty (TKA) is a reliable procedure for end-stage osteoarthritis with excellent long-term survivorship, but approximately 15% of patients are not satisfied. Pain catastrophizing (PC) has been proposed as a potential cause but current evidence is limited to smaller studies with short-term follow-up. Our goal was to assess outcomes following TKA in a large cohort with and without PC.
