Periprosthetic Fractures in Patients With Total Knee Arthroplasties

Ten patients with total knee arthroplasties sustained periprosthetic fractures. Nine of these were supracondylar fractures, and one occurred in the middle one-third of the tibia. These patients were treated with conservative methods in two cases and internal fixation with plate and screws in three cases. The remaining five patients were treated with intramedullary fixation using a specially designed revision prosthesis with long intramedullary stems. The best results wer achieved through the revision arthroplasty, based on walking ability, range of motion, and early rehabilitation.
