Patellar Fractures in Total Knee Arthroplasty

  • Charles L. Nelson
  • Russell E. Windsor


As surgical technique and implants have improved, the longevity of femoral and tibial components and the clinical results following total knee arthroplasty have improved as well. The primary source of complications following total knee arthroplasty in many series has been related to the extensor mechanism or patellofemoral joint.1–3 These complications have included unexplained anterior knee pain, patellar clunk syndrome, patellar instability, patellar component disassociation, patellar component wear, patellar loosening, quadriceps or patellar tendon rupture, and patellar fracture. Patellar resurfacing may decrease the incidence of anterior knee pain, and has decreased the rate of reoperation following total knee arthroplasty.4–6 However, this may occur at the potential expense of increased rates of patellar implant—related complications including patellar component loosening, patellar subluxation or dislocation, and patellar fracture.1,4,7,8
