Development of the OrthoView Radiographic Imaging Device for Knee Osteoarthritis Using General X-ray Machines

Abstract

Osteoarthritis is a prevalent health problem among the elderly. OrthoView radiography plays a key role in disease diagnosis and disease severity assessment, and proper patient positioning is essential. This study aimed to 1) design and develop an OrthoView radiographic imaging device compatible with general X-ray machines, 2) evaluate radiographers' satisfaction with the device, and 3) assess the quality of radiographic images obtained using the device. The research and development were conducted with seven radiographers and 10 OrthoView radiographic images. The device consists of a motorized patient-lifting system and a radiopaque, adjustable scaled ruler ranging from 10 to 50 cm in height, with a maximum weight capacity of 120 kg. Radiographers reported high levels of satisfaction (mean =4.29–4.86), with material durability and aesthetics receiving the highest ratings (mean = 4.86). The radiographic images were rated as good to excellent in quality (mean scores =4.1–4.7), with anatomical accuracy achieving the highest score (mean = 4.7). Inter-rater reliability ranged from substantial to almost perfect (kappa = 0.65–0.85). In conclusion, the OrthoView device appears to improve diagnostic accuracy, reduce the risk of repeated radiation exposure, and provide a cost-effective solution for use in general hospitals.
