목적: 대퇴골의 관절 외 변형을 가진 환자에서 관절 내 교정을 이용한 슬관절 전치환술의 결과를 분석하고자 한다.
대상 및 방법: 대퇴골의 관절 외 변형을 동반한 23예에서 슬관절 전치환술을 시행하였다. 연령은 평균 58.0세이었고, 추시 기간은 평균 54.7개월이었다. 미국 슬관절학회의 슬관절 점수, 기능 점수를 조시하였고, 역학적 축을 계측하였다. 변형의 위치가 원위부에 위치한 권(Ⅰ군, 16예)과 근위부 또는 간부에 위치한 군(Ⅱ군, 7예)의 결과를 비교하였다.
결과: 슬관절 점수는 술 전 평균 47.8, 최종 추시 시 평균 91.6이었고, 기능 점수는 술 전 평균 46.9, 최종 추시시 평균 89.1이었다. 역학적 축은 술 전 평균 내반 7.7˚, 술 후 평균 내반 1.0˚이었다. 최종 추시시 슬관절 점수는 Ⅰ군 90.1, Ⅱ군 95.0, 기능 점수는 Ⅰ군 87.8, Ⅱ군 92.1이었다. 술 후 히지의 역학적 축은 Ⅰ군 내반 2.0˚, Ⅱ군 외반 1.3˚이었다(p=0.042).
결론: 대퇴골의 관절 외 변형을 가진 환자에서 관절 내 교정을 이용한 슬관절 전치환술 후 만족할 만한 결과를 얻을 수 있었다. 심한 변형이 대퇴골 원위부에 위치한 경우 하지 정렬의 교정이 불완전할 수 있으므로 주의하어야 한다.

Purpose: To investigate the result of total knee arthroplasty (TKA) using an intra-articular correction in patients with extra-articular deformity of the femur. Materials and Methods: We performed 23 TKAs in 23 patients with extra-articular deformity of the femur. The mean age was 58.0 years and the follow-up period averaged 547 months. The American Knee Society"s knee and function score were evaluated, and the mechanical axis (MA) was measured. Sixteen knees with a deformity in the distal third of the femur were assigned to group Ⅰ and 7 knees with a deformity in the proximal or middle third were assigned to group Ⅱ. Between groups differences in results were analyzed Results: The average knee score was 47.8 preoperatively and 91.6 at the last follow-up. The average function score was 46.9 preoperatively and 89.1 at the last follow-up. The MA averaged varus was 7.7˚ preoperatively and 1.0˚ postoperatively. The average knee score at the last follow-up was 90.1 in group Ⅰ and 95.0 in group Ⅱ. The average function score at the last follow-up was 87.8 in group Ⅰ and 92.1 in group Ⅱ. The MA averaged varus was 2.0˚ in group Ⅰ and 130 in group Ⅱ (p=0.042). Conclusion: TKA in conjunction with intra-articular correction produced satisfactory results for patients with an extra-articular deformity of femur. The possibility of incomplete correction of limb alignment should be carefully considered, especially in cases with a severe deformity at the distal third of the femur.
