Repair of ruptured quadriceps tendon with Leeds–Keio ligament following revision knee surgery

We describe the use of the Leeds–Keio ligament to reconstruct a neglected quadriceps tendon rupture following revision knee arthroplasty. The Leeds–Keio ligament has been used in the treatment of patellar tendon ruptures complicating primary knee arthroplasty with good result—but may, as this report shows, also be successfully applied to address deficiencies of the quadriceps tendon in the revision setting, with continued good function for 2 years.
