High Midterm Survival Rate of Uncemented Total Knee Arthroplasty After High Tibial Osteotomy: A Case-Control Study.

Background: Total knee arthroplasty (TKA) following high tibial osteotomy (HTO) is technically more demanding than TKA in a native knee. Studies have reported increased intraoperative and postoperative complication of TKA with previous HTO. The aim of this study is to compare the survival and complication rates and functional outcomes of uncemented TKA with previous HTO to primary TKA at our institution over a decade.

No influence of obesity on survival of cementless, posterior-stabilised, rotating-platform implants.

Introduction: This study compares survival and outcomes in four total knee arthroplasty (TKA) populations defined by baseline body mass index (BMI). We hypothesised that there would be no difference in survival between the groups.

Materials And Methods: Using an initial cohort of 1059 TKAs, BMI was systematically measured prior to surgery.
