Trabecular metal components 'effective alternative to cemented tibial models'

New research has found that the trabecular metal component can provide a strong alternative to cemented tibial models.

A study published in the Journal of Bone and Joint Surgery has found that the risk of early aseptic loosening was 0.0.

The survey examined a total of 70 subjects undergoing total knee replacement, with radiostereometric analysis being performed post-operatively to assess the success of the operations.

While the authors found that a subset of the trabecular metal groups migrated extensively following the procedure, these had stabilised within a year.

The study stated: "The purpose of this study was to compare an uncemented trabecular metal tibial component with a conventional cemented stemmed tibial component of the same design."

Earlier this month, research published by the journal found that cemented total knee replacements have a higher level of survivability.

In addition, a further comparison with uncemented operations found no statistically significant difference in Knee Society scores.
