Computer-Assisted Navigation in Patellofemoral Arthroplasty: a New Technique to Improve Rotational Position of the Trochlea

Maltracking or subluxation is one of the complications of patellofemoral arthroplasty. We questioned whether the computed navigation system can improve patellar tracking in patients with patellofemoral arthroplasty (PFA). Between 2007 and 2010 we performed 15 patellofemoral arthroplasties using the Ceraver PFA and navigation assistance. Fifteen other… (More)
