The aim of this study was to compare the preoperative patients' expectations with their postoperative satisfaction after arthroplasties of the hip and knee, using a visual analogue scale. The comparison was made in a group of 44 patients after 44 primary knee and hip joint arthroplasties. A visual analogue scale (VAS) was used for the assessment of expectation and satisfaction. The mean preoperative expectation VAS was 14.8 (SD: 14.3). The mean patient satisfaction at time of follow up was 13.0 (SD : 21.1). We found no agreement in the preoperative patient's expectation satisfaction versus postoperative satisfaction (p = 0.66). Moreover in our study, the patients expected to be less satisfied than they actually were at follow-up, which is shown with the Bland and Altman method. It appears that patients are not capable of predicting the outcome of the joint arthroplasty, which could be influenced by negative preoperative information on complications and risks. Pain and functional disability are probably the most important factors for the patients' satisfaction after arthroplasty surgery.

Objectives: To systematically evaluate the efficacy of lateral unicompartmental knee arthroplasty (LUKA) and total knee arthroplasty (TKA) in the treatment of isolated lateral compartment knee osteoarthritis (LCKO), and to provide guidance and a basis for selecting surgery in clinical practice.
Methods: Inclusion and exclusion criteria for literature were established, appropriate effect indicators were selected, and PubMed, Web of Science, Embase, Medline, Cochrane Library, and CNKI databases were searched using a computer. The Newcastle Ottawa scale (NOS) was used to evaluate the quality of the literature.

Introduction: In 2020, 368 million people globally were affected by knee osteoarthritis, and prevalence is projected to increase with 74% by 2050. Relatively high rates of dissatisfactory results after total knee arthroplasty (TKA), as reported by approximately 20% of patients, may be caused by sub-optimal knee alignment and balancing. While mechanical alignment has traditionally been the goal, patient-specific alignment strategies are gaining interest.

Background: Bicruciate-retaining (BCR) prostheses have been introduced to recreate normal knee movements by preserving both the anterior and posterior cruciate ligaments. One of the surgical procedures essential to the success of BCR total knee arthroplasty (TKA) is preservation of the tibial eminence. However, in our clinical experience, we found that a well-preserved tibial eminence changed its shape chronologically after the operation.

Background: Chronic periprosthetic joint infection (PJI) presents a major challenge in knee arthroplasty, with varying success rates reported for two-stage exchange arthroplasty (EA) and a lack of consensus on managing failures from such procedures. This study evaluated repeat two-stage EA outcomes for knee PJI after initial treatment failure to identify the risk factors for reimplantation unsuitability and reinfection.
Methods: We analyzed 114 patients who underwent repeat EA for chronic knee PJI between 2010 and 2018.

Introduction: Patients who have poorly controlled diabetes mellitus are at increased risk of periprosthetic joint infection (PJI). Nevertheless, an optimal preoperative hemoglobin A1c (HbA1c) threshold has not been established. This study sought to identify preoperative HbA1c thresholds that were predictive of adverse outcomes for total hip (THA) and total knee arthroplasty (TKA) patients.
