Abstract
|
|
|
The knee joint is one of large joints which is related to weight bearing. When degenerative arthritis of the knee develops, the normal physiologic biomechanics of the knee can be transformed to pathomechanics as a causes of- disability and angular deformity.
Attention is directed to pathomechanical abnormalities of the degenerative knee, especially of angular deformity with radiogram being taken in the standing weight bearing position comparing with routine non-weight bearing radiogram. The purpose of the study was to investigate some significant evidence of weight bearing roentgenogram.
The case material consisted of forty knees of degenerative arthritis in thirty one patients. Roentgenograms were taken with antero-posterior projection of the knee in the non-weight bearing and weight bearing positions.
The femoro-tibial angle was compared the non-weight bearing with the weight bearing roentgenogram of the same knee. Thirty two of total forty knee were observed increased angular deformity in the weight bearing roentgenograms, eighteen with varus and fourteen with valgus deformity.
It is to be expected weight bearing antero-posterior roentgenogram will be valuable for part of the routine roentgenographic examination of patients with osteoarthritis of the knee joint.
