Evaluating axial alignment and knee phenotypes in a young Indian population, using X-rays converted to three-dimensional bone models, and their relevance in total knee arthroplasty.

Purpose: The standard principle of total knee arthroplasty (TKA) targeted by most orthopaedicians is the alignment of the lower limb in a neutral mechanical axis. However, for several patients the neutral mechanical alignment is not normal. Aligning these patients to a neutral mechanical axis may not result in desirable outcomes as it may feel unnatural.

A Study of Surgical Accuracy with X-Ray-Based Patient-Specific Instrument (X3DPSI) vs Conventional Instrument in Total Knee Arthroplasty Surgeries.

Introduction: Patient-specific instruments (PSI) have been shown to be a good solution in getting accurate bone cuts in total knee arthroplasty (TKA) in many studies. However, the need for an extra CT/MRI makes the existing PSI method costly and unsafe. X-ray-based PSI can solve these problems, if proven to be accurate.

CT-Based 3D Reconstruction of Lower Limb Versus X-Ray-Based 3D Reconstruction: A Comparative Analysis and Application for a Safe and Cost-Effective Modality in TKA.

Aim: Patient Specific Instrumentation (PSI) with 3D bone models have been used to improve the outcomes of Total Knee Arthroplasty (TKA). The PSI, however, needs a CT (Computed tomography)/MRI scan to reproduce a bone-based model. However, CT is not a routine imaging method in the TKA and has challenges such as high radiation exposure and increased investigation cost.

Incidence and antimicrobial profile of extended-spectrum β-lactamase producing gram-negative bacterial isolates: An in-vitro and statistical analysis.

Objectives: There is an extensive incidence of extended-spectrum beta-lactamases (ESBLs), principally in the hospital environment across the world. The present study was designed to discover the frequency of ESBL-production among the clinical isolates of Escherichia coli, Klebsiella pneumonia, and Pseudomonas aeruginosa. The study also focused on determining their liability to the selected antimicrobials.

Classification of hard core and petty criminals using anthropometric measurements.

The purpose of the present study was to compare the somatometric measurements among hard core criminals, petty criminals and community people. Using standard anthropometric procedures, somatometric dimensions were studied on 250 subjects each from the three groups: (i) experimental (hard core criminal) group, (ii) control-I (petty criminal) group, and (iii) control-II (community people) group. Univariate analysis of variance was used for making comparisons of somatometric measurements between these groups in the univariate case.

A study of risk factors in recidivistic criminals.

A study was carried out under the aegis of Indian Council of Medical Research, New Delhi with objectives to identify psychosocial, physical, psychiatric, anthropometric and psychometric risk factors in recidivistic criminals, which could predict a future recidivistic criminal. The paper presents study observations on 250 experimental, 250 control-1 and 250 control-2 subjects. Experimental and control-1 subjects were recruited from district jails of Uttar Pradesh and control-2 from the community.
