In Vivo Sagittal Plane Kinematic Analysis Of Asian Knees After Oxford Unicompartmental Knee Arthroplasty (UKA) And Its Relation With Functional Outcome And Sex Of Patient

It is proposed that UKA mimics normal knee kinematics as the ligaments are not sacrificed in this surgery. We hypothesise that there is a difference in kinematics among patients with different sex and functional outcomes. Objectives: To correlate in vivo Knee Kinematics relationship with Functional outcome and sex of patient after unicompartmental knee arthroplasty Methods: In vivo sagittal plane kinematics of 20 knees was analysed using the MATLAB software after performing step up and deep knee bend exercise under fluoroscopy. The patellar tendon angle (PTA) was plotted at varying knee flexion angles (KFA). Patients were divided into 2 groups: one with Oxford Knee Score (OKS) more than 40 and the other with less than 40. Another 2 groups based on sex were made(male and female). Using p value less than 0.05 Results: The in vivo sagittal plane kin...

Nowadays, synthetic vanillin is being preferred as a flavouring agent in foods, beverages and pharmaceuticals. Chemically, it is a phenolic aldehyde with the molecular formula C8H8O3. Over years it has been used as a flavor in sweet foods like chocolates & ice creams, in cosmetics like perfumes, and in pharmaceuticals to mask the unpleasant odor and tastes in medicines. Also, vanillin-HCl is extensively used a visualizing agent in Thin Layer Chromatography. Quite recently, vanillin has been studied by researchers all over the world for its pharmacological effects. The compound has exhibited remarkable effects in treatment and management of several pathological conditions. This review focuses on the different reported pharmacological activities of vanillin.

Early Results of Oxford Mobile Bearing Medial Unicompartmental Knee Replacement (UKR) with the Microplasty Instrumentation: An Indian Experience

Microplasty (MP) instrumentation was introduced in 2012 as an improvement over phase 3 instrumentation. Advantages of this instrumentation include conservative tibial cut, decreased tibial re-cut rate and improved component alignment. We report the results of UKR with the new instrumentation in a consecutive series with a minimum follow-up of 2 years. A prospective study of 115 cemented medial Oxford UKRs implanted in 89 patients was done. Post-operative alignment of the tibial and femoral components was analysed. Patient reported outcome measures were recorded using Oxford Knee Score (OKS) and the American Knee Society Score (KSS). Tegner Activity Scale (TAS) was used to record the activity level. 115 consecutive medial Oxford UKRs were studied. All patients were followed up annually in this prospective ethically approved study. The mean follow-up was ...

Anteromedial osteoarthritis is highly prevalent in Indian patients, and OUKR is the ideal treatment option in such cases. Uncertainty prevails about the best method to determine femoral component size in OUKR. Preoperative templating has been shown to be inaccurate, while height- and gender-based guidelines based on European population might not apply to the Indian patients. Microplasty instrumentation introduced in 2012 introduced the sizing spoon, which has the dual function of femoral component sizing and determining the level of tibia cut. We aimed to check the accuracy of sizing spoon and also to determine whether the present guidelines are appropriate for use in the Indian patients. A total of 130 consecutive Oxford mobile bearing medial cemented UKR performed using the Microplasty instrum...

The purpose of this study is to assess whether there is a correlation between functional outcome and knee kinematics. From a cohort of consecutive cases of 150 Oxford medial UKA, patients with fair/poor functional outcome at 1-year postsurgery (Oxford Knee Score [OKS] < 34, n = 15) were identified and matched for age, gender, preoperative clinical scores, and follow-up period with a cohort of patients with good/excellent outcome (OKS ≥ 34, n = 15). In vivo kinematic assessment was performed using step-up and deep knee bend exercises under fluoroscopic imaging. The fluoroscopic videos were analyzed using MATLAB software to measure the variation in time taken to complete the exercises, patellar tendon angle, and bearing position with knee flexion angle. Mean OKS in the fair/poor group was 29.9 and t...
