Claim:
1. A prosthesis for treating disorders of the knee in the patellofemoral compartment of the knee, the prosthesis comprising: a fixation portion configured to be mounted to the tibia at a fixation site proximate the upper tibial extremity and medially or laterally of the tibial tuberosity; a spanning section configured and dimensioned to extend cranially and laterally or medially from the fixation portion in a direction towards the tibial mid-line; and a displacement portion having an overall curvature around an axis generally parallel to the tibial shaft when the fixation portion is mounted at the fixation site and configured and dimensioned to (i) extend from the spanning section further laterally or medially under patellar tendon and in engagement therewith, and (ii) displace the patellar tendon anteriorly sufficiently to alter the location, angle or magnitude of forces exerted thereby on the patella so as to achieve a therapeutic effect in patellofemoral compartment of the knee.
