Brief summary
SCORE® is a primary total knee arthroplasty implant designed to achieve stability through congruency, has a rotating platform and a mobile bearing surface. Unlike cemented fixed-bearing implants, more congruent rotating platforms aim to reduce contact stress peaks and polyethylene wear, also to reduce contact strain peaks at the bone-implant interface to reduce the risk of loosening.The design of the femoral trochlea has also become more anatomical to improve patellar stability and reduce the number of patellofemoral complications. SCORE®TKA (Amplitude, Valence, France) uses traditional instrumentation and computer navigation (Amplivision®) to control bone cuts, mechanical alignment and ligament balance. Very satisfying results for the Score implant have been reported in the literature however there we were unable to locate any published results affirming the stability this implant affords using high quality measurements, as that of RSA.
Interventions
Patients will receive an uncemented tibial component Score Mobile bearing Total Knee Arthroplasty. The operation takes 45-60 minutes and is performed in the standard fashion, excepting the implantation of RSA beads around the implant. The operation date and limb side will be recorded from the surgeons private database. No other theatre details have relevance in this commonly performed surgery. Followup assessment postoperatively, at 3 months, 1 and 2 years will radiographically assess implant
