ABSTRACT
Objective:
To determine the overlapping area of the femoral condyle facet on which the patellofemoral and tibiofemoral joint surfaces move and to measure the pressures on such area in order to better design the length of femoral trochlea prosthesis in patellofemoral arthroplasty.Methods:
Eight fresh cadaver knees were mounted on Instron 8501 biomechanics tester,and simulated physiologically weight-bearing situation of knee from standing to flexion position. Such overlapping area was drawed up with stain method and the contact pressures were measured with Fuji pressure film.Results:
There existed an overlapping contact area on the femoral condyle facet within the patellofemoral contact area when knee flexion was 75? or larger. The tibiofemoral contact pressure was higher than the patellofemoral pressure in the area.Conclusion:
The femoral trocher prosthesis should cover the whole contact area of patellofemoral joint.
