Abstract :
Purpose : Patient dissatisfaction after total knee arthroplasty (TKA) is not uncommon; even when a surgery is rated very successful from the surgeon eye. This mismatch between surgeon and patient satisfaction might be reduced with more evidence-based endpoints to reach by the surgeon, when performing TKA. We hypothesized the presence of a relationship between patient satisfaction and the position in the sagittal plane of the femoral component. Material and method : This is a retrospective study of 60 TKA from an initial series of 100 patients. Our inclusion criteria were : a true lateral postoperative X-ray of the TKA showing 10 cm of the distal diaphysis; and filled Oxford Knee Score questionnaire (OKS) with 14 months of minimum follow- up. Results : We found three types of sagittal plane position of the femoral components: • Type A or neutral: 31TKA (52%) • Type B or in extension: 23 TKA (38%) • Type C or in flexion: 6 TKA (10%). The Oxford Knee Score in our series was: in type A (neutral): 78.2%, type B (extension): 75.1%, type C (flexion): 68.4%. Conclusion : This study shows that a neutral position of the femoral component in the sagittal plane gives the highest patient satisfaction according to OKS, with a better outcome for extension position when compared to flexion position.
