Bugra}, keywords={unicondylar knee arthroplasty, proximal fibular osteotomy, finite element analysis}, abstract={<p style="text-align:justify;"> <span style="font-size:11px;">Besides conservative methods, various surgical treatment modalities including high tibial osteotomy (HTO), unicondylar knee  </span> <span style="font-size:11px;">arthroplasty (UKA) and total knee arthroplasty (TKA) have been applied for the treatment of medial gonarthrosis. Combined application  </span> <span style="font-size:11px;">of UKA and PFO may enable longer implant survival by reducing the load over the implant and subsequent implant wear. We aimed to  </span> <span style="font-size:11px;">investigate on a finite element (FE) model, whether integrating a fibulectomy would reduce the contact stresses on the UKA implant.  </span> <span style="font-size:11px;">Finite Elements model developed to evaluate changes in the biomechanical environment resulting from UKA implantation and fibula  </span> <span style="font-size:11px;">osteotomy for use in the study. Menisci, bone and implants modeled as linear elastic isotropic material. We developed a 3D knee joint  </span> <span style="font-size:11px;">model with UKA implant and performed PFO on this model. A vertical load of 800N was applied anatomically to the femoral head.  </span> <span style="text-align:justify;font-size:11px;line-height:1.42857;">Stress on the tibial component was assessed before and after fibulectomy was performed. The contact stress was evaluated for UKA  </span> <span style="text-align:justify;font-size:11px;line-height:1.42857;">the mean stress (10,2 MPa ± 6,8) and for UKA + Fibulectomy (9,44 MPa ± 6,5). Combined application of PFO and UKA reduced contact  </span> <span style="text-align:justify;font-size:11px;line-height:1.42857;">stresses over the implant on a Finite Element Model. The findings of our observe additionally offer which might also additionally  </span> <span style="text-align:justify;font-size:11px;line-height:1.42857;">enhance the affected patient satisfaction, medical effects and implant survivorship of UKA. </span> </p>}, number={2}, publisher={Eskişehir Osmangazi University}
