ONE-STAGE TOTAL KNEE ARTHROPLASTY WITH PRE-EXISTING FRACTURE DEFORMITY

The International Society for Technology in Arthroplasty (ISTA), 28th Annual Congress, 2015. PART 4.



Abstract

The aim of the study was to assess the results of treating knee osteoarthrosis with total knee arthroplasty (TKA) after previous tibia and/or femur fractures resulting in axial limb deformities. Thirty-six knees (34 patients) were operated on. At the most recent follow-up, 4.8 years after surgery, all but one patient demonstrated an improvement in both clinical and functional KSS. This male patient required revision after 2 years due to tibial component aseptic loosening. Improved range of motion was generally noted, especially extension, however, two patients with both tibia and femur fractures had worse results. TKA is an effective method of treatment for patients with arthrosis after a previous femur or tibia fractures. When deformity is severe semi-constrained or constrained, implants with extensions may be necessary.
