Comparison of 2 Radiographic Techniques for Measurement of Tibiofemoral Joint Space Width
BACKGROUND No consensus is available regarding the best method for measuring tibiofemoral joint space width (JSW) on radiographs to quantify joint changes after injury. Studies that track articular cartilage thickness after injury frequently use patients' uninjured contralateral knees as controls, although the literature supporting this comparison is limited. PURPOSE (1) To compare JSW measur...
متن کاملChange in knee structure and change in tibiofemoral joint space width: a five year longitudinal population–based study
BACKGROUND Change in knee cartilage volume is frequently used as a proxy for change in knee joint space width over time, but longitudinal data on these associations is limited. We aimed to determine whether change in knee cartilage volume, new or worsening meniscal extrusion (ME), meniscal tears and cartilage defects over 2.4 years correlated with change in joint space width (JSW) over 5 years ...
متن کاملKnee joint space width measurement: an experimental study of the influence of radiographic procedure and joint positioning.
We studied the influence of the radiographic procedure and joint positioning on knee joint space width (JSW) in 10 healthy volunteers, and the intrareader reproducibility of JSW measurements on radiographs performed 2 weeks apart using a standardized procedure. Results show that a 5 or 10 downward inclination of the X-ray beam and 15 or 30 of induced external foot rotation significantly reduced...
متن کاملQuantifying the tibiofemoral joint space using x-ray tomosynthesis.
PURPOSE Digital x-ray tomosynthesis (DTS) has the potential to provide 3D information about the knee joint in a load-bearing posture, which may improve diagnosis and monitoring of knee osteoarthritis compared with projection radiography, the current standard of care. Manually quantifying and visualizing the joint space width (JSW) from 3D tomosynthesis datasets may be challenging. This work dev...
