Intended Use

The VEGA Knee System is indicated for use in reconstruction of the diseased by ostearthritis, theumatoid arthritis, post-traumatic arthritis, the need to revise failed arthroplasties where pain, deformity or dysfunction persist, and for patients suffering from correctable valgus or varus deformity and moderate flexion contracture. Posterior Stabilized (PS) components are also for aon-functioning posterior cruciate ligament and severe anteroposterior instability of the knee joint. The VEGA Knee is designed for use with bone cement. The Columbus Total Knee System is indicated for use in reconstruction of the diseased by osteoarthritis, theumatord arthritis, post-traumatic arthritis, the need to revise failed arthroplasties where pain, deformity or dysfunction persist, and for patients suffering from correctable valgus or varus deformity and moderate flexion contracture. Posterior Stabilized (PS) components are also for and on non-functioning posterior cruciate ligament and severe anteroposterior instability of the knee joint. The Columbus Knee is designed for use with bone cement.

Device Story

The VEGA and Columbus Knee Systems are semi-constrained cemented total knee prostheses. This submission introduces All Poly Tibia (posterior stabilizing and cruciate retaining) implants and an optional centralizer. Components are implanted by orthopedic surgeons in a clinical/OR setting to replace diseased knee joints. The device functions as a mechanical bearing surface; the femoral component articulates against the tibial insert/All Poly Tibia. The centralizer ensures consistent cement mantle around the keel. The system restores joint function, reduces pain, and corrects deformities. X-ray markers (titanium/tantalum/stainless steel) allow for post-operative radiographic visualization. The device is intended for single use.

Clinical Evidence

Bench testing only. Evidence includes biomechanical testing, wear evaluation, mechanical failure (break) analysis, and surface roughness analysis. Biocompatibility data provided for X-ray markers. Validation and verification data provided for new surgical instruments.

Technological Characteristics

Materials: CoCrMo alloy (optional ZrN coating), UHMWPE (tibial insert, patella, All Poly Tibia), PMMA (centralizer), PEEK (tibial plug). X-ray markers: stainless steel (patella), titanium peg and tantalum ball (All Poly Tibia). Design: Semi-constrained cemented prosthesis. Sterilization: Sterile, single-use.

Indications for Use

Indicated for patients requiring knee joint reconstruction due to osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, or revision of failed arthroplasties/osteotomies with persistent pain, deformity, or dysfunction. Includes patients with correctable valgus/varus deformity and moderate flexion contracture. Posterior Stabilized (PS) components indicated for absent/non-functioning posterior cruciate ligament and severe anteroposterior knee instability.

Regulatory Classification

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).

# SUBSTANTIAL EQUIVALENCE

Aesculap Implant Systems, LLC believes that the introduction of All Poly Tibia posterior stabilizing and cruciate retaining implants with an optional centralizer are substantially equivalent to the currently marketed Aesculap VEGA Knee System® (K101281, K121879, K140452, and K143106), Columbus Total Knee System (K022672; K023788; K053390; K071220; K071449 and K120955) and Triathlon® All-Polyethylene Tibial Implants (K123166).

# DEVICE DESCRIPTION

All Poly Tibia posterior stabilizing and cruciate retaining implants are a line extension to the VEGA Knee System® and Columbus Total Knee System, respectively. The posterior stabilizing version is being introduced to the VEGA Knee System® and the cruciate retaining, deep dish version is being introduced to the Columbus Total Knee System. The subject implants are available with an optional centralizer.

VEGA Knee System® is a semi-constrained cemented prosthesis with a posterior stabilized (PS) design. Columbus Total Knee System includes both cruciate retaining and posterior stabilizing variants of the femoral, tibial and meniscal components.

Vega Knee System® Columbus Total Knee System

> K143443 Page 2 of 2

For both knee systems, the femoral component, tibial plateau and extension stems are manufactured from Cobalt Chromium Molybdenum alloy (CoCrMo), available with an optional Zirconium nitride (ZrN) coating. The tibial gliding surface (insert), patella and All Poly Tibia are manufactured from Ultra High Molecular Weight Polyethylene (UHMWPE). The optional centralizer, designed to be used with the All Poly Tibia is made of polymethyl methacrylate (PMMA). The patella and All Poly Tibia incorporate X-ray markers. The materials of the X-ray markers in the patella are wrought stainless steel and the All Poly Tibia X-ray markers consist of a titanium peg and a tantalum ball. The tibial plug is made of PEEK.

VEGA and Columbus Knee Systems are made up of numerous components available in various sizes. The VEGA Knee System® is compatible with Aesculap Columbus cruciate retaining/posterior stabilizing tibial plateaus (CR/PS and CRA/PSA) and augments.

VEGA and Columbus components are sterile and intended for single use only.

# INDICATIONS FOR USE

The VEGA Knee System® and the Columbus Total Knee System are indicated for use in reconstruction of the diseased knee joint caused by osteoarthritis, rheumatoid arthritis, posttraumatic 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.

Posterior Stabilized (PS) components are also for absent or non-functioning posterior cruciate ligament and severe anteroposterior instability of the knee ioint.

The VEGA Knee System® and Columbus Total Knee System are designed for use with bone cement.

# TECHNOLOGICAL CHARACTERISTICS

The addition of All Poly Tibia posterior stabilizing and cruciate retaining implants with an optional centralizer does not change the fundamental scientific technology of VEGA Knee System® or of Columbus Total Knee System.

Similar to the Triathlon® All-Polyethylene Posterior Stabilizing (PS) and Condylar Stabilizing (CS) tibial implants (K123166), the introduction of All Poly Tibia is a monoblock meniscal/tibial UHMWPE component whose design is based on the respective system's UHMWPE tibial insert and CoCrMo tibial components.

VEGA All Poly Tibia (PS) components are compatible with the articulating sizes of the VEGA femur and patella. Similarly, Columbus All Poly Tibia (CR deep dish) is compatible with the articulating sizes of the Columbus femur and patella. The optional centralizer was previously cleared in Aesculap's Excia Hip system (K042344). It is designed to ensure a consistent cement mantle around the keel.

# PERFORMANCE DATA

As a result of the risk analysis, biomechanical testing and a comparison evaluation of wear was performed. The results of the wear evaluation, mechanical failure (break) and surface roughness analysis raised no new issues of safety and efficacy for the design modifications described herein. In addition to the data above, biocompatibility of the X-ray markers was provided as well as information on the validation and verification of the new instruments.
