Intravenous versus topical tranexamic acid administration in primary total knee arthroplasty: a meta-analysis.
This meta-analysis was designed to compare the effectiveness and safety of intravenous (IV) versus topical administration of tranexamic acid (TXA) in patients undergoing primary total knee arthroplasty (TKA) by evaluating the need for allogenic blood transfusion, incidence of postoperative complications, volume of postoperative blood loss, and change in haemoglobin levels. ⋯ Meta-analysis, Level III.

Remaining mild varus limb alignment leads to better clinical outcome in total knee arthroplasty for varus osteoarthritis.
Postoperative neutral limb alignment [femorotibial mechanical axis (FTMA) 180° ± 3°] is generally considered to be one of the prerequisites for successful total knee arthroplasty (TKA). However, the influence of residual malalignment on clinical and functional outcomes after TKA is unknown. Therefore, the purpose of this study was to investigate the relationship between postoperative limb alignment and clinical outcomes in Asian patients who underwent primary TKA. ⋯ IV.

ReviewGreater pre-operative anxiety, pain and poorer function predict a worse outcome of a total knee arthroplasty.
Around 10-30 % of patients are dissatisfied with the results of their total knee arthroplasty (TKA). This review aimed to identify and evaluate the predictors of outcome measured by the three domains of health-related quality of life (pain, stiffness and function). The focus was on pre-operative psychological factors as related to other patient-related variables. ⋯ II.

Kinesiophobia and depression affect total knee arthroplasty outcome in a multivariate analysis of psychological and physical factors on 200 patients.
To evaluate the effects of kinesiophobia on the outcomes of total knee arthroplasty (TKA), and to investigate whether kinesiophobia represents an independent factor influencing the surgery success or whether the observed effects are driven by other physical or psychological aspects such as anxiety and depression. ⋯ IV.

What is the optimal valgus pre-set for intramedullary femoral alignment rods in total knee arthroplasty?
In total knee arthroplasty (TKA), intramedullary guides are often used for aligning the distal femoral cutting block. Because of the highly varying angles between the mechanical axis and the anatomical femoral axis (AMA), different valgus pre-sets have been recommended. The present study investigated the optimal valgus pre-set (measuring the AMA in long-leg radiographs or at 5°, 6°, 7° or 8° valgus) to align the cutting block perpendicularly to the mechanical axis. ⋯ Diagnostic study, Level II.
