BACKGROUND Patellofemoral complications are one of the main problems after Total Knee Arthroplasty (TKA). Retropatellar pressure distribution after TKA can contribute to these symptoms. Therefore we evaluated retropatellar pressure distribution subdivided on the ridge, medial and lateral surface on non-resurfaced patella before and after TKA. Additionally, we analyzed axial femorotibial rotatio...

EDITORIAL Table 1 summarizes recommendations based on the presented papers. To prevent infection, it is critical to identify high-risk patients and control those risks prior to surgery. Action must be taken at every step of the surgical process, from preoperative to postoperative protocols, including intraoperative measures. In this Editorial some recent issues that surgeons should explor...

CONTEXT Total knee arthroplasty (TKA) is one of the most common and costly surgical procedures performed in the United States. OBJECTIVE To examine longitudinal trends in volume, utilization, and outcomes for primary and revision TKA between 1991 and 2010 in the US Medicare population. DESIGN, SETTING, AND PARTICIPANTS Observational cohort of 3,271,851 patients (aged ≥65 years) who underwen...

Background: Due to the obvious differences in the natural course of rheumatoid arthritis (RA) and osteoarthritis (OA),different functional outcomes might be expected after Total Knee Arthroplasty (TKA) in these distinct patients. Althoughseveral studies have reported the objective outcome of TKA in RA and OA patients, few studies have compared postoperativepatient-satisfaction levels.Methods: I...

Total knee arthroplasty (TKA) is one of the most successful procedures in modern orthopedic surgery, providing high patient satisfaction rate. As a result, the number of patients undergoing TKA is increasing in number every year and more patients would be inclined to have the operation in near future . The demand for TKA is expected to grow 673% between 2005 and 2030. Knee surgeons are using mo...

Purpose To evaluate the effects of femoral lateral bowing on coronal alignment after total knee arthroplasty (TKA) and examine whether the use of navigation helps obtain better postoperative coronal alignment and component position. Materials and Methods Radiological results and outlier rates were compared between the conventional TKA group and the navigation-assisted TKA group, and factors a...

INTRODUCTION Rheumatoid arthritis (RA) is one of the major indications of total hip (THA) or knee (TKA) arthroplasty. International studies have suggested that RA is a risk factor for prosthesis infections. OBJECTIVES To compare patients with RA and patients with osteoarthritis (OA) of other etiologies with regard to the incidence of prosthesis, incisional, and other systemic postoperative in...

BACKGROUND Accurate femoral rotational alignment is of vital importance for successful total knee arthroplasty (TKA). The value of computer-assisted surgery TKA (CAS-TKA) in increasing the accuracy of femoral rotational alignment remains controversial. We hypothesize that outcomes are related to the severity of preoperative varus and valgus deformity and that CAS-TKA may be beneficial under cer...

Background: Over 600 000 total knee arthroplasties (TKA) are performed per year in the United States, and about 20% of patients report poor and/or unsatisfactory outcomes following TKA. Additionally, about 22.5% of patients undergoing TKA meet clinical criteria for major depressive disorder. Previous research has revealed an association between preoperative depression and increased postoperativ...
