Use of the Leeds–Keio prosthetic ligament for repair of patellar tendon rupture after total knee arthroplasty

We describe a technique for repair of the patellar tendon rupture after total knee arthroplasty (TKA), using the Leeds–Keio (L-K) prosthetic ligament. Two patients were followed for a mean of 38 months. Knee extension power and improved function were obtained in both cases. Use of the L-K ligament is a treatment option for repair of patellar tendon rupture following TKA.
