다국어 초록 (Multilingual Abstract)

The purpose of this study was to assess the cause of malaligment in cases using intramedullary goide in MGII TKA. One hundred and fifty four knees of 105 patients were involved in this study, The underlying diseases were 111 OA, 38 RA, 2 tuberculosis, 1 fracture, 1 charcot joint, and 1 spontaneous osteanecrosis. The femorotihial angle was graded into varus(less than 0 ), 1 -4 valgus, 5 -8 valgus and 9 -10 valgus. The results were analyzed according to different diseases with chi-square test. There were 4(2.6%) varus knees0ess than 0 ), 12(7,8 $quot;lo) 1 4' valgus knees, 130(84.4%) 5 8 valgus knees and 8(5.2'Po) 9 -10 va1gus knees, showing inconstant femorotibial angle. Rheumatoid knees were involved in 3 of 4 varus knees and 8 of 12 1 -4 valgus knees, showing increased frequency of varus tendency compared to other diseases (P=0.000).
From these results it would be suggested that intramedullary guide should be carefully used to achieve good alignment in TKA.
