MicroPort Orthopedics has announced that it witnessed increased adoption of its Kinematic Alignment (KA) approach for the Evolution Medial-Pivot knee system to improve patient outcomes.
The KA technique replicates the natural alignment of a patient’s pre-disease knee joint.
A surgeon can make bone cuts using specialised instrumentation depending on each individual patient’s pre-diseased state. This reduces the need to change soft tissue structures of the patient such as ligaments and potentially results in a more minimally invasive approach.
MicroPort noted that most of the traditional knee replacement surgeries use mechanical alignment, which focuses on a perpendicular tibial resection, non-anatomic distal, posterior femoral cuts and ligament releases, for proper placement of the knee implant.
However, the natural state of a patient’s pre-arthritic knee made using this approach account for roughly 2.2% of the population.
The combination of the new alignment technique with Evolution Medial-Pivot Knee represents the latest in complete knee replacement technology and improves potential patient satisfaction and outcomes.
MicroPort Orthopedics president Benny Hagag said: “The adoption of this advanced surgical technique allows our medial-pivot surgeons to combine the benefits of medial-pivot kinematics and stability with a kinematic approach designed to individualise knee implantation to best suit each patient.
“By putting the knee exactly where it was pre-disease, in its natural position, the Kinematic Alignment approach has shown in clinical studies to improve both patient satisfaction and motion range.”
Launched in 1998, the MicroPort Medial-Pivot knee system features a medial-pivoting, ball-in-socket design and provides improved stability and restoration of natural motion.
The combination of medial-pivot design and the latest alignment technique technology allows for a more patient-specific, anatomic total knee replacement that results in higher patient satisfaction.
