Uncemented Miller-Galante total knee replacement

Summary.

Sixty-one primary uncemented Miller-Galante total knee replacements were implanted in 55 patients between June 1988 and December 1990. The results of routine radiological and clinical follow up carried out at an average of 1.3 years and 6.2 years after operation were used for evaluation. The Knee Society clinical score improved from 47.8 points before operation to 83.3 points one year after, and had progressed further to 87.6 points at the recent follow-up. The functional score improved from 45 points before operation to 75.23 points at early follow up, and 81.3 points at the recent review. Although radiological analysis showed that the femoral and tibial components overall were placed perpendicular to the mechanical axis of the limb, sufficient correction of the mechanical axis was not achieved to within ±10  mm deviation from the centre of the knee in 22 cases, with varus or valgus deformity remaining. No early or late infection occurred in this series. The uncemented Miller-Galante total knee replacement shows good biological fixation of both components. Wear of the metal-backed patellar and tibial polyethylene lead to a revision rate of 19% after 5 years.
