An investigation of the posterior tibial vascular plexus has established certain specific features of its structure both in normality and in patients with postthrombotic disease. The alterations found require an individual approach to choice of surgical measures which is finally determined intraoperatively. At the present time surgical interventions on the posterior tibial veins in patients with postthrombotic disease are thought to be of three types: extended resection, extravasal correction and plasty of the posterior tibial veins.

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.

Tarsal tunnel syndrome (TTS) refers to compression of the posterior tibial nerve as it traverses the tarsal tunnel in the ankle. First described by Keck and Lam in 1962, TTS is an underdiagnosed cause of heel pain and foot dysfunction. The tarsal tunnel contains the tibial nerve, posterior tibial artery, and tendons of the tibialis posterior, flexor digitorum longus, and flexor hallucis longus muscles.

Purpose: >The aim of this multicenter study was to analyze the potential impact of patient demographics and cementation technique towards the development of radiolucent lines (RLLs) in primary total knee arthroplasty (TKA). It was hypothesized that cementation techniques, including higher cement volume, double-layer cementation technique and hardening in full extension, reduce RLL incidence by improving stability, whereas demographic factors such as age, BMI and smoking may increase RLL risk by affecting bone quality and mechanical loading.
Methods: Altogether, 776 patients (median age: 70.

Background: The effect of axial rotation between the femoral neck and ankle joint (total rotation [TR]) on normal knees is unknown. Therefore, this study aimed to investigate the TR effect on normal knee kinematics.
Methods: Volunteers were divided into groups large (L), intermediate (I), and small (S), using hierarchical cluster analysis based on TR in the standing position.
