Range-precision improvement of a time-of-flight range sensor using dual reference plane sampling.

This study aimed to achieve high range precision in the sub-100 µm order with time-of-flight (TOF) range imaging for 3-D scanners. The precision of a TOF range imager was improved using dual reference plane sampling (DRPS). DRPS using two short-pulse lasers reduces driver jitter, which limits the range precision below sub-100 µm.

High and Varied Anterior Condyle of the Distal Femur Is Associated with Limited Flexion in Varus Knee Osteoarthritis.

Objective: This study aimed to evaluate variations in anterior condylar height (ACH) of the distal femur in varus knee osteoarthritis and evaluate the association between ACH and knee flexion.

Design: Computed tomography (CT) images of 171 knees (143 patients; age 73.7 ± 8.

A greater reduction in the distal femoral anterior condyle improves flexion after total knee arthroplasty in patients with osteoarthritis.

Background: The effect of an anterior condylar height (ACH) change after total knee arthroplasty (TKA) is not well-known. The effect of an ACH change was evaluated on postoperative knee flexion, New Knee Society Scores (2011KSS), and patellofemoral contact force.

Methods: The study included 101 knees that underwent TKA.
