accepted for publication – EMBC 2014

referenceThe paper I submitted to EMBC 2014 has been accepted for publication! During my PhD thesis I’ve conceived a miniaturised actuation system to be embedded in the tibial component of an instrumented knee prosthesis for the evaluation and correction of collateral ligaments imbalance conditions in the postoperative period. A second model, feasible but bulkier, is considered as an alternative solution and is presented in this other publication. The sections Publications and Curriculum Vitae are now up-to-date.

TitleA Miniaturised Actuation System Embedded in an Instrumented Knee Implant for Postoperative Ligament Imbalance Correction

Abstract: During Total Knee Arthroplasty surgery, the orthopaedic surgeon has to set up proper balance conditions for the two lateral ligaments of the knee. Such ligament tensioning procedure is performed manually and mainly depends on the surgeon’s experience. Unfortunately, inaccuracies are unavoidable and may give rise to serious postoperative complications. In the worst-case scenario, the only solution to this problem is represented by revision surgery. In order to cope with this problem, this work proposes a novel instrumented tibial component able to detect knee imbalance conditions in the postoperative period. A miniaturised actuation system embedded in the tibial baseplate allows to restore optimal balance conditions without resorting to revision surgery.
