Market Watch: Knee Product Launches

By Julie A. Vetalice

ORTHOWORLD estimates see global knee joint reconstruction revenue growing in the low single digits for the coming years, approaching $10.5BB in 2022. Analysts suggest that 2019 will see a boost in growth based on factors such as broader release of robotic assistance technologies, effects from the removal of total knee replacement from the inpatient-only setting and episodic bundling for total joint procedures.

The following companies have bolstered their knee lines with these launches from the past 12 months.

Corin launched the Unity Knee™, featuring EquiBalance™ instrumentation for ligament balancing and soft tissue preservation. Enabling ligament balancing and medial collateral ligament isometry supports functional knee positioning, implant stability and performance, which may yield a reduction in post-op discomfort.

DePuy Synthes commenced U.S. launch of the ATTUNE® Revision Knee, available in fixed bearing and rotating platform options. The device features AOX™ anti-oxidant polyethylene material, ATTUNE GRADIUS™ Curve gradually-reducing femoral radius geometry to address sliding of the femur on the tibia and GLIDERIGHT™ Articulation to support accurate replication of normal patello-femoral kinematics.

DJO launched the OaraScore™ Outpatient Arthroplasty Risk Assessment tool as a direct response to the removal of TKA procedures from the Centers for Medicare & Medicaid Services inpatient-only list. Using multi-disciplinary algorithms and data, this software provides clinicians with information needed to assess an appropriate post-operative length of stay after TKA. OaraScore’s values are derived by evaluating nine critical co-morbidity factors and overall medical conditions, all in real time. In addition to using OaraScore to determine if patients are low or high risk for outpatient surgery, the software also tracks readmission rates and compares encrypted data to all other physicians utilizing the tool.

Episurf Medical commenced limited European launch of the Epioscopy® artificial intelligence-based knee visualization tool, designed to provide interactive, 3D images of possible structural deviations in the pre-planning process for minimally invasive procedures. Following the visualization, Epioscopy enables an implant to be tailored to a patient’s specific anatomy and pathology.

Medacta launched the MOTO™ Medial Partial Knee, a compartment-specific, fixed-bearing solution for unicompartmental knee arthroplasty, of particular interest for surgeon use in an outpatient setting. Design of each compartment derives from an anthropometric database of >45,000 CT and MRI knee scans, while instrumentation is designed to support precise bone resection.

Ortho Development announced the first surgery to take place in the People’s Republic of China using the Balanced Knee® System. BKS implants and instrumentation address primary and revision procedures; >70,000 of the devices are implanted worldwide. A patented locking mechanism is designed to minimize micro-motion between the plastic tibial insert and titanium tibial baseplates.

Smith & Nephew commenced full release of the JOURNEY™ II XR bi-cruciate retaining total knee in Japan and the U.S. Features include a design intended to accurately replicate the knee anatomy, a tibial baseplate designed for optimal fixation and fatigue strength, use of the VERILAST™ bearing surface to support implant survivorship and enabling technologies like NAVIO™ robotics-assisted surgery and VISIONAIRE™ patient-matched adaptive guides.

Zimmer Biomet commenced launch of the Persona® Trabecular Metal™ Tibia. Alongside the Persona TM Femur and TM Patella, the tibial design rounds out the company’s fully cementless total knee offering.
