  • Abstract
  • Look Inside

 Total knee arthroplasty (TKA) is a technically demanding procedure, and it is difficult to obtain an appropriate alignment and perfect soft tissue balancing during the operation especially in patients with severely varus aligned knee. The clinical results in 22 knees with a minimum preoperative standing femorotibial angle of 195° were evaluated. The average knee score improved from 38.6 to 76.6 points, and the average function score rose from 39.1 to 80.9 points. Although the varus deformity was corrected form 198.8±4.3° to 176.1±4.9°, it was over 180° in 4 knees at follow-up. The average varus instability was 6.9±3.4°, but it was not clinically significant. It is important to obtain good alignment and to reconstruct the medial collateral ligament with suitable tension in TKA.
