From the Guidelines
The Attune Knee System necessitates exact measurements to minimize complications and optimize outcomes in knee replacement surgery, as emphasized by the importance of precise implant sizing, alignment, and positioning in achieving successful results. The significance of accurate measurements in knee replacement surgery is highlighted by the potential consequences of measurement errors, which can lead to instability, limited range of motion, abnormal wear patterns, or persistent pain 1. According to the AAOS Clinical Practice Guideline Summary, strong evidence supports the notion that the use of navigation or PSI for routine TKA shows no demonstrable advantage, suggesting that conventional instrumentation can be sufficient for achieving accurate measurements 1.
Key considerations for exact measurements in the Attune Knee System include:
- Proper implant sizing to ensure a secure fit and optimal function
- Accurate alignment to minimize wear and tear on the implant and surrounding tissues
- Precise positioning to restore normal joint mechanics and facilitate smooth movement
- Soft tissue balance to ensure stability and comfort in the knee joint
Surgeons should rely on their clinical judgment and experience, as well as patient preferences and values, when making treatment decisions, including the use of specialized instruments and computer-assisted navigation or robotic assistance to measure the patient's unique anatomy 1. The Attune system's multiple sizing options and anatomically matched components are designed to accommodate individual patient variations, but these benefits can only be realized when accurate measurements guide implant selection and placement. Ultimately, the importance of exact measurements in the Attune Knee System cannot be overstated, as it directly impacts the patient's post-operative function, comfort, and implant longevity.
From the Research
Importance of Exact Measurements in ATTUNE Knee System
- Exact measurements are crucial in the ATTUNE Knee System to ensure proper fit and alignment of the implant, which can affect the outcome of the surgery 2, 3.
- Studies have shown that the ATTUNE Knee System provides better range of motion and addresses patient-reported instability, but exact measurements are necessary to achieve these benefits 2, 4.
- The use of robotic arm-assisted total knee arthroplasty (RA-TKA) can improve preoperative planning and intraoperative decision-making, allowing for more accurate bone resection and implant sizing 5.
- Accurate measurements can also help reduce the risk of complications, such as radiolucent lines, which can be detected in some patients with the ATTUNE Knee System 6.
Factors Affecting Measurement Accuracy
- Patient characteristics, such as anatomy and bone quality, can affect measurement accuracy 3.
- The experience and skill of the surgeon can also impact measurement accuracy and the overall outcome of the surgery 2, 4.
- The use of advanced technologies, such as 3D modeling and robotic assistance, can improve measurement accuracy and reduce the risk of human error 5.
Clinical Outcomes and Measurement Accuracy
- Studies have shown that the ATTUNE Knee System can provide excellent clinical outcomes, including improved range of motion and reduced pain, when exact measurements are used 2, 4, 6.
- However, the importance of exact measurements in achieving these outcomes is not always emphasized, and further research is needed to fully understand the relationship between measurement accuracy and clinical outcomes 3.
