Abstract: (2 Views)
Introduction: Periprosthetic patellar fractures are uncommon but challenging complications following total knee arthroplasty (TKA) or tumor prosthesis reconstruction. Treatment strategies depend on the stability of the implant, integrity of the extensor mechanism, and fracture displacement. Although surgical fixation is often recommended for patellar fractures in native knees, conservative treatment may be appropriate in selected patients with knee arthroplasty.
Case Presentation: We report three patients with previous knee arthroplasty who sustained patellar fractures following low‑energy trauma. The first case was a 76‑year‑old woman who developed a patellar fracture after a fall. The second case involved a 64‑year‑old woman with diabetes mellitus and a history of left total knee arthroplasty (TKA) performed six years earlier. The third case was a 45‑year‑old man with a history of tumor prosthesis implantation following resection of a suspected osteosarcoma ten years earlier. All patients sustained traumatic patellar fractures after falling to the ground. Due to a stable prosthesis, conservative management with immobilization or a hinged knee brace was chosen. Follow‑up imaging and clinical evaluation demonstrated satisfactory healing and good functional outcomes without surgical intervention.
Conclusion: Selected periprosthetic patellar fractures may be successfully treated with conservative management. Avoiding surgery in appropriately selected patients can reduce complications and provide favorable clinical outcomes.
