Abstract
BackgroundThe Orthopaedic Data Evaluation Panel (ODEP) monitors the performance of primary total knee arthroplasty (TKA) implants against guidance provided by the National Institute for Health and Care Excellence (NICE) and issues ratings based upon survivorship data meeting or exceeding 95 % at 10-year follow-up. The objectives of the current study were to determine if the survivorship for the ADVANCE Medial-Pivot System in an arthroplasty registry exceeds this threshold and if its survivorship is significantly different than that of all other cemented bi-, tricompartmental, minimally stabilized, and fixed bearing TKAs in the same registry.MethodsThe database of an arthroplasty registry was searched for all TKAs performed with the subject system and all other cemented TKAs. The Kaplan-Meier survivorship for the subject system was compared to the NICE criteria and also that of all other cemented TKAs. Complication modes were also examined for the two groups.ResultsThe 10-year survivorship for the included 506 TKAs using the subject system (96.3 %) exceeded the NICE guidelines of 95 % at 10 years. Survivorship also exceeded that of all other cemented TKAs (95.7 %) in the same registry, but the difference was not significantly different.ConclusionsThe subject system was associated with survivorship that exceeds the NICE guidelines at 10 years and is similar to that of other cemented TKA systems. The use of this unique tibial insert design does not negatively impact component survivorship.

The Orthopaedic Data Evaluation Panel (ODEP) in the UK was established in 2002 to monitor the performance of primary total hip arthroplasty (THA) implants against guidance provided by the National Institute for Health and Care Excellence (NICE) [1]
There were 506 TKAs performed with the subject system by 30 orthopedic surgeons at more than ten hospitals during the time period of interest
Summary
The Orthopaedic Data Evaluation Panel (ODEP) monitors the performance of primary total knee arthroplasty (TKA) implants against guidance provided by the National Institute for Health and Care Excellence (NICE) and issues ratings based upon survivorship data meeting or exceeding 95 % at 10-year follow-up. The Orthopaedic Data Evaluation Panel (ODEP) in the UK was established in 2002 to monitor the performance of primary total hip arthroplasty (THA) implants against guidance provided by the National Institute for Health and Care Excellence (NICE) [1]. The primary objective of this study was to determine if the long-term survivorship of the ADVANCE Medial-Pivot System in an arthroplasty registry exceeds 95 % at 10 years follow-up. The secondary objective was to determine how the survivorship for this system compared to all other cemented bi-, tricompartmental, minimally stabilized, and fixed-bearing TKAs in the same registry
