Activit-E™ Vitamin E polyethylene demonstrates superior wear resistance compared to other materials in simulated knee joint conditions.
Multilevel Modeling of Resection Accuracy: Insights from 10,144 Clinical Cases using A Contemporary Computer-Assisted Total Knee Arthroplasty System (Abridged Version)
As a successful treatment for advanced inflammatory and degenerative knee arthritis, total knee arthroplasty (TKA) is projected to expand by 600% to more than three million cases annually by 2030.
Total Knee Arthroplasty with CAOS Augmentation
A recent technology added CAOS augmentation to conventional mechanical instruments, removing the need for significant instrument relearning. The system has been shown to have a minimal learning curve and offers good usability and has been demonstrated to be non-disruptive to the surgical flow during its early adoption, reported by a subjective survey of users.
CAOS Augmented Mechanical Instrumentation Provides Versatility and Improved Accuracy During Total Knee Arthroplasty
Accurate positioning of the knee prosthesis is critical for the success of total knee arthroplasty (TKA). However, with mechanical (neutral) alignment surgical philosophy, only 70-80% of the conventional TKA cases can achieve satisfactory accuracy (within ±3° of varus/valgus relative to the mechanical axis).
CAOS TKA Provides Improved Functional Outcomes Compared to Conventional TKA
Computer-assisted orthopaedic surgery (CAOS) has been shown to offer a clear advantage regarding surgical accuracy in total knee arthroplasty (TKA) with a body of research studies demonstrating a significant reduction of alignment outliers compared to conventional TKA instrumentation. However, conflicted data exists in the literature for a consensus regarding the advantage of CAOS technology in clinical outcomes or satisfaction rates for the patient.
Anterior Cruciate Ligament Reconstruction Using Platelet Rich Plasma and Tenomend™
Anterior cruciate ligament (ACL) injuries are commonly encountered in the practice of sports medicine with current literature estimating an incidence of 100,000 to 200,000 cases per year.
Learning of A CAOS Enhanced Mechanical Instrument System for Total Knee Arthroplasty: A CUSUM Analysis
Computer-assisted orthopaedic surgery (CAOS) has been shown to offer improved accuracy to total knee arthroplasty (TKA) compared to conventional techniques.1 Despite promising results, one of the drawbacks for surgeons to adopt CAOS technology may be the requirement of switching from conventional to CAOS-specific instruments.
Assessing the Learning Curve of a Contemporary Total Knee System Using Advanced (CUSUM) Analysis
As hospitals are facing mounting financial pressures in the current economic environment, time spent in the operating room has been identified as one of the most costly areas of hospital operations. As such, introduction of a new total knee arthroplasty (TKA) system to clinical care should demonstrate a minimum learning effort requirement.
If Computer-Assisted Surgery is More Accurate, Why Isn’t it More Prevalent?
There are two things that all total knee surgeons can agree on when it comes to imageless computer navigation: It is more accurate than mechanical instrumentation in obtaining coronal alignment of the limb, and it is painful to adopt into one’s practice.
Fit of Modern Femoral Knee Implant Design to Native Trochlear Groove
Total knee arthroplasty (TKA) is a mature surgical procedure for the treatment of endstage knee arthritis. Despite its overall high clinical success, many patients still report pain and discomfort after TKA, with approximately 20% of the patients not satisfied with the clinical outcomes.
