Six cases of periprosthetic fractures of the distal femur following total knee arthroplasty were treated with a newly developed fork plate. Instead of the blade of the condylar plate, this implant features two prongs that are adaptable in length. Because of the space between the prongs, the distal femoral fragment surrounds the anchorage pegs of the prosthesis and can be gripped near the joint line. ⋯ Follow-up ranged between 2 and 54 months. All patients were mobilized immediately postoperatively. Full weight bearing and bone consolidation was achieved by 9 weeks postoperatively.
