AbstractPosterior-stabilized, rotating platform knee prosthesis design was aimed to decrease polyethylene wear for the sake of improving implant survivorship. The purpose of the present prospective study was to evaluate the long-term clinical and radiographic results as well as the survival rate after using a rotating platform, posterior-stabilized knee prosthesis at a minimum of 10 years at a Middle East institution. We compared the results with reports in the literature on western populations. From January 2002 to June 2008, 96 patients (106 knees) underwent total knee arthroplasty (TKA) using a cemented rotating platform posterior-stabilized knee prosthesis. At a mean of 11.5 ± 1.3 years, 85 patients (95 TKAs) were available for clinical, radiographic, and implant survival analysis. At the final follow-up, 78.9% of the patients had excellent Knee Society Scoring system score, the average knee flexion was 110 ± 17 degrees, the average anatomical knee coronal alignment was 186 ± 2 degrees and 187 ± 3 degrees for varus and valgus knees, respectively. Five (5.2%) knees were revised of these: two for bearing dislocation, two for aseptic loosening, and one for infection. The Kaplan-Meier survival rate was 94.7% for all revisions and 97.8% when only revision for aseptic loosening considered as the end point. At a long-term follow-up, reasonable clinical and radiographic outcomes had been achieved after using a rotating platform, posterior-stabilized knee prosthesis in our population with acceptable survival rate reaching up to 95%, which is comparable to reports from the western population.

AbstractThere is a lack of clinical outcomes reported for the rotating bearing knee (RBK) total knee arthroplasty (TKA), which is a second-generation rotating platform knee, with purported benefits over earlier versions. The purpose of the study was to report the complications, short-term (minimum 1 year) patient-reported outcomes and long-term (up to 15 years) procedure survival in a consecutive series of patients receiving a rotating platform TKA (RBK) from an independent clinic. A retrospective analysis of a single-surgeon, private/public practice, with prospectively collected data in a subset of patients were performed. A total of 1,130 procedures (primary, revision from unicompartmental knee arthroplasty (UKA) to TKA) were crossmatched with manufacturer records. Clinical outcomes (complications, reoperations) were summarized and linked to patient-reported outcome measures (Eq. 5D, KSS-function, Oxford knee score [OKS]). OKS results were classified using minimally clinical important difference (MCID) and patient acceptable symptom state (PASS). PROMs were summarized and regression models used to determine relationships between patient factors and outcomes in this cohort. Cumulative percent revision was reported by the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) and compared between the senior author and national data using Kaplan–Meier survival analysis. We report a complication rate of 19.7% with the majority (> 60%) being thromboembolic events and complaints of stiffness. Significant improvements were observed in general health, knee pain, and function with > 89% exceeding the MCID for the OKS and > 65% exceeding the PASS for the OKS at an average follow-up of 3.2 years. We report a cumulative revision rate of 4.3% at 5 years and 4.8% at 14 years, with significantly lower revision rates in females and patients aged 55 to 64 years compared with AOANJRR data for fixed bearing designs. The RBK rotating platform TKA provides good functional outcomes, with relatively low revision and complications rates at up to 14 years follow-up. This design in conjunction with a gap balancing technique may be advantageous in certain patient subgroups.
