Khow YZ, Liow MHL, Lee M, et al. - In this study, the clinical impacts of femoral component coronal alignment were evaluated in a cohort of fixed-bearing unicompartmental knee arthroplasty with clinical and radiological follow-up of 10 years. Researchers examined a prospectively collected registry data of 264 consecutive, cemented, primary fixed-bearing medial unicompartmental knee arthroplasties performed at a single institution from 2004 to 2007. They assessed the femoral component coronal angle (FCCA), tibial component coronal angle, and hip-knee-ankle angle on postoperative radiographs. The Knee Society Knee and Function Scores, Oxford Knee Score, and Short Form-36. were applied to conduct a clinical assessment at 6-month, 2-year, and 10-year follow-up. The results considered that FCCA may affect long-term clinical outcomes, but not short-term clinical outcomes nor 10-year survivorship. The data revealed that given similar limb alignment, coronal, and sagittal component positioning, a larger FCCA was correlated with poorer outcomes at a 10-year follow-up.
