Filter by:The goal of this observational study is to investigate the relationships between the medial longitudinal arch (MLA) height of the foot and clinical and radiological characteristics of knee osteoarthritis in adult patients 50 aged and over. The main questions it aims to answer are: - Is there any relationship between knee pain and disability in knee osteoarthritis and MLA height? - Is there any relationship between the radiologic severity of knee osteoarthritis and MLA height? - Is there any relationship between knee joint alignment in knee osteoarthritis and MLA height?
Rotational deformities, such as femoral (thigh bone) and tibial (leg bone) torsion, are established causes of patellofemoral (kneecap joint) pain and instability. Currently, computerized tomography (CT) remains the gold standard assessment tool for measuring the degree of rotational deformity. However, there is disagreement as to the thresholds for surgical correction as it is suggested that some individuals compensate for the deformity better than others. Gait (walking) analysis provides important information of the biomechanical parameters undertaken in the knee joint during dynamic movement. In patients with rotational deformities, several variations from normal gait patterns have previously been described by several authors. Therefore, it is questioned whether these parameters can be correlated with the static features of CT scans, in individuals with rotational deformities. This study aims to determine whether gait analysis is a useful tool in the diagnosis and treatment pathway for rotational abnormalities in patellofemoral pain or instability. A secondary aim of this study will be to assess whether gait analysis can detect a rotational deformity in the lower limb and determine whether the changes seen are proportionate to the level of deformity. Patients to be included in this retrospective study are, adult patients, with presumed rotational deformity of the lower limb, with anterior knee pain, who have been referred to the gait laboratory for assessment, and for CT rotational profiles. Only patients who have given consent to the gait laboratory for their information to be utilised in research will be included. Two researchers will record measures of rotational deformity from the CT images. The gait laboratory assessment includes measurements of biomechanical parameters based on joint movement through the gait cycle - these parameters will be assessed and compared with CT measures for correlation. All research will be conducted at the hospital where the gait laboratory assessment has been performed.
The comfort and fit of the residual limb within a prosthetic socket are of primary concern for many amputees. The residual limb is typically covered by nonbreathable and non-thermally conductive materials that can create a warm and ultimately moist environment. The investigators have developed a silicone liner approach to passively conduct heat from the skin using thermally conductive elastomers. A technology that can provide thermal control while retaining adequate suspension, weight, and other prosthetic characteristics would benefit many prosthesis wearers.
In the international literature there are only few publication about the normal biomechanical parameters of the lower limb examined prospectively in healthy population. The goal of our study to determine 15 anatomical and biomechanical parameters of the lower limb using 3D reconstruction based on upright, stereo radiographs in young, healthy volunteers.
Randomized Controlled Study to determine if preservation of ligaments provides increased functional ability post-operatively in comparison to traditional TKA which sacrifices soft tissue.
The purpose of this prospective clinical data-collection is to document the performance and clinical outcomes of the Vanguard™ Complete Knee System.
