The relationship between the surgical epicondylar axis (SEA) and the rotational axis of the distal femur remains unclear. We investigated the relationship between the SEA and the distal femur and whether the SEA can be used as the rotational axis of the knee. Angular and linear measurements of 70 femora at 0°, 30°, 60°, 90°, and 120° of flexion were recorded. Results showed that the SEA was a logical and appropriate parameter as a principal axis for knee flexion at least between 0° and 60° of flexion. The study has important implications for the design and positioning of femoral components in total knee arthroplasty.

Aims: The aim of the present study was to evaluate the morphology of the distal medial femoral surface during coronal osteotomy in medial closed wedge distal femoral varus osteotomy (MCWDFO) using plain CT.
Methods: Twenty knees (mean age, 55.3 years) were included.
Purpose: It is not known where the anatomical axis of rotation on the tibial side will be in kinematic alignment (KA), a rapidly expanding area of total knee arthroplasty (TKA) alignment technique today. The purpose of this study was to define the tibial axis for KA-TKA.
Methods: Fifty patients who underwent computed tomography (CT) examination of the lower extremities at a single institution were included.

Objective: The aim of this study was to describe the development of a total elbow replacement (TER) technique in swine and report the outcome of TER in a Kunekune sow (61 kg) with severe elbow osteoarthritis.
Methods: The technique was developed by operating on three pig cadavers (Yorkshire 40-50 kg). The TATE Elbow implant fit was confirmed with modeling to the patient's computed tomography imaging.

Background and objective The epicondyles are commonly used surgical reference landmarks for elbow arthroplasty and external fixator application. This study aimed to investigate whether the epicondylar axis differed from the elbow's true flexion-extension (F-E) axis in terms of both rotational difference and translational offset. Methods Three-dimensional (3D) models of 15 cadaver elbows were created.
