The Columbus Total Knee System is indicated for use in reconstruction of the diseased knee joint caused by osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, the need to revise failed arthroplasties or osteotomies where pain, deformity or dysfunction persist, and for patients suffering from correctable valgus or varus deformity and moderate flexion contracture.
The Columbus Knee is designed for use with bone cement.
The Ultra Congruent Tibial Insert is a gliding surface for the Columbus Total Knee System made from UHMWPE. The ultra congruent insert is designed with increased contact area that provides improved stability in flexion and extension. The Columbus UC gliding surfaces range in height from 10 mm to 20 mm and in size from T0/T0+ to T5
The provided text does not contain information about specific acceptance criteria, study methodologies, sample sizes, expert qualifications, or ground truth establishment relevant to the performance evaluation of the Columbus Total Knee System Ultra Congruent Tibial Insert.
Instead, the document is a 510(k) summary for a medical device. It describes:
- Company and Device Information: Manufacturer, contact, trade name, common name, classification, regulation number, and product code.
- Substantial Equivalence: The claim that the new device is substantially equivalent to previously cleared devices (predicate devices) based on similar design and materials.
- Device Description: A brief overview of the device, its material (UHMWPE), and its intended design features (increased contact area for improved stability).
- Indications for Use: The medical conditions and patient types for which the device is intended.
- Technological Characteristics: Comparison of the new insert with predicate devices, highlighting similarities in shape, size, material, and increased surface area.
- Performance Data (Planned): This section states what testing will be done or is applicable, rather than reporting actual results or acceptance criteria met. It lists "All required testing per 'Draft Guidance for the Preparation of Premarket Notifications (510(k)s) Applications for Orthopedic Devices-The Basic Elements' will be done where applicable. In addition testing will be completed as applicable per the following:" followed by a list of relevant guidance documents for orthopedic implants and materials.
- FDA Correspondence: A letter from the FDA confirming the device's substantial equivalence to predicate devices and allowing it to be marketed, subject to general controls.
Key Takeaway:
The document describes the regulatory pathway and rationale for market clearance (510(k) process) for the Columbus Total Knee System Ultra Congruent Tibial Insert. It does not provide the detailed performance study results or acceptance criteria that would typically be found in a clinical trial report or a comprehensive performance data section. The "Performance Data" section merely outlines the types of guidance documents under which testing would be conducted, not the results themselves.

SUBSTANTIAL EQUIVALENCE
Aesculap®, Inc. believes that the Ultra Congruent Tibial Insert for the Columbus Total Knee System is a line extension of the standard and deep dish tibial inserts that were cleared as components of Aesculap's Columbus Total Knee System (K022672 and K023788). It is also substantially equivalent to the ultra congruent inserts that were cleared for the VKS Knee System (K022204).
DEVICE DESCRIPTION
The Ultra Congruent Tibial Insert is a gliding surface for the Columbus Total Knee System made from UHMWPE. The ultra congruent insert is designed with increased contact area that provides improved stability in flexion and extension. The Columbus UC gliding surfaces range in height from 10 mm to 20 mm and in size from T0/T0+ to T5

Dear Mr. Hull:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21

§ 888.3560 Knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a knee joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components and a retropatellar resurfacing component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.
