RA膝のX線的検討

抄録

Roentgenographic examination was carried out in 181 knees of 91 patients with rheumatoid arthritis. 14 cases (37%) of RA patients over 60 and 14 cases (42%) of the patients whose disease durations were over 10 years were the grade IV or V of Larsen's method. We judged that these cases had operative indication and did TKR to 18 joints (9%) out of them. Judging from the narrowing of the femoral-tibial joint space, 65% of the cases showed normal alignment, 31% medial narrowing alignment, and 4% lateral narrowing alignment.
