Scorpio Cruciate Retaining (CR) Outcomes Study

2014-08-27 03:19:49 | BioPortfolio


The purpose of this study is to evaluate the design and functional performance of the Scorpio Total Knee Cruciate Retaining (CR) System.


The study design is that of a prospective, multi-center clinical trial. The Howmedica Osteonics Scorpio® Cruciate Retaining (CR) Total Knee System is to be implanted for evaluation in this study. This device system is commercially available and is cleared for a cemented intended for use.

The study group will consist of a maximum of 265 cases, requiring primary total knee replacement, and diagnosed with non-inflammatory arthritis. All subjects will be implanted with a femoral component, a tibial insert, a tibial tray and a resurfaced patella. Subjects receiving bilateral total knee replacements will represent two cases. Study participants will be recruited from 5 institutions.

Subjects will be evaluated preoperatively and at follow-up intervals of 7 wks (± 2 wks), 3 months (± 3 weeks), six months (±1 month and an optional visit), 12 months (± 2 months) and annually thereafter (± 2 months). Each subject will be followed for five years post-implantation.

The objectives of this study are to:

1. Evaluate the effect of system component design on functional performance.

2. Evaluate the effect of system component design by comparing postoperative functional and radiographic findings with preoperative.

3. Evaluate complications and the rates in which they occur.

Influence of Posterior Tibial Slope on Kinematics After Cruciate-Retaining Total Knee Arthroplasty.

The purpose of this study was to investigate the influence of posterior tibial slope (PTS) on knee kinematics after cruciate-retaining total knee arthroplasty (CR-TKA). These influences were evaluated...

Knee motion symmetry was not restored in patients with unilateral bi-cruciate retaining total knee arthroplasty-in vivo three-dimensional kinematic analysis.

Although unilateral total knee arthroplasty (TKA) is successful in restoring function, there are concerns in relation to asymmetric gait patterns. Bi-cruciate retaining (BCR) TKA design preserves both...
