Abstract
Aims: To assess the medium term results of uncemented Low Contact Stress Rotating platform total knee replacement.
Methods: One hundred and nine primary uncemented Low Contact Stress rotating platform total knee replacements in 85 patients were reviewed 4 to 12 years after the operation as a prospective study on consecutive cases. 106 knees received uncemented metal backed rotating patella. All patients were followed up annually with subjective questionnaires and radiological assessment.
Results: At the time of final review, 69 patients with 87 rotating platform total knee replacement were alive. There was no loss to follow-up. The American Knee society score was used for objective assessment. The average knee score was 86.42 and the average functional score was 65.1. No evidence of radiological loosening was observed in any patient. One knee was revised because of medial collateral ligament laxity. The ten-year survival rate was 99.08% (95% CI - 91.9-99.9).
Conclusion: The uncemented LCS rotating platform knee replacement seems to be reliable at medium-term follow-up.
