Abstract
Periprosthetic fractures involving total knee arthroplasty (TKA) components, particularly involving the patella, can present a significant challenge regarding orthopedic surgery. This technical note outlines an approach for the reconstruction of complicated periprosthetic transpatellar fractures, with poor bone stock, utilizing autogenous iliac graft. This kind of procedure requires careful preoperative evaluation of imaging, precise intraoperative planning, and strict postoperative management to achieve adequate postoperative results. The inventive option of utilizing an autogenous iliac graft for reconstruction suggests its potential benefits in addressing the unique biomechanical demands of patellar fractures in TKA patients with poor bone stock. Key technical aspects of this approach are highlighted and include graft harvest, graft preparation, and fixation techniques. Overall, this technique can provide a golden standard bailout for periprosthetic transpatellar fracture reconstruction and potentially offer orthopedic surgeons a comprehensive framework for addressing this challenging clinical scenario.
