Protecting a Patellar Ligament Reconstruction after Proximal Tibial Resection: A Simplified Approach. [JOURNAL ARTICLE]
Clin Orthop Relat Res 2008 Apr 19.
Limb salvage in tumor surgery has encouraged the development of megaprostheses. However, reattaching the ligamentum patellae poses a particular problem: avulsion and/or extensor lag may lead to poor function. We describe a new technique of patellar ligament reconstruction. The technique involves reattachment of the patellar ligament to the tibial tuberosity of the proximal tibial megaprosthesis, which has a porous surface created, and the repair is protected with a cerclage wire through the patella and the prosthesis. In 10 consecutive patients, the range of motion averaged 95 degrees (median, 90 degrees ; range, 70 degrees -120 degrees ), and the mean extension lag averaged 4 degrees (median, 0 degrees ; range, 0 degrees -20 degrees ). We had one case of patellar ligament avulsion. This technique resulted in good quadriceps function and a low incidence of complications. Level of Evidence: Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.
