From the Research
I cannot provide a picture of Attune femoral posterior stabilized Size 4 right vs left implants as I don't have the capability to share images. The Attune Knee System by DePuy Synthes includes femoral components designed specifically for right and left knees to better match natural anatomy. The main difference between right and left femoral components is their asymmetric design, particularly in the trochlear groove (the path where the patella slides) and the lateral flange, which is slightly higher on the lateral side to prevent patellar subluxation. Size 4 is one of the standard sizing options in the Attune system, representing a specific dimensional fit for patients with corresponding femoral measurements. To see actual images comparing these components, I would recommend consulting the manufacturer's product catalog, speaking with a DePuy Synthes representative, or reviewing surgical technique guides available through official medical supply channels.
Some studies have shown that design modifications in posterior-stabilized knee systems, such as the Attune system, can reduce anterior knee pain and complications following total knee replacement 1. These modifications may include improved femoral rollback, improved femoral dislocation resistance, minimized wear, and improved longevity. However, the specific differences between the right and left Attune femoral posterior stabilized Size 4 implants are not explicitly stated in the provided evidence.
In terms of clinical outcomes, a study published in 2020 found that a newer posterior-stabilized knee design, which incorporates a left and right specific femoral component and smoother trochlear groove, resulted in significant improvements in overall pain and patellofemoral pain, and reduced manipulation rates post-operatively 1. However, this study did not specifically compare the Attune system to other posterior-stabilized knee systems.
Overall, while the provided evidence does not include explicit comparisons of the Attune femoral posterior stabilized Size 4 right vs left implants, it suggests that design modifications in posterior-stabilized knee systems can have a positive impact on clinical outcomes. Therefore, it is recommended to consult the manufacturer's product catalog or speak with a DePuy Synthes representative to obtain more information about the specific differences between the right and left Attune femoral posterior stabilized Size 4 implants.
