Device Story

MPO Knee Instruments are surgical accessories used to assist in total knee arthroplasty; includes patient-specific PROPHECY Pre-Operative Navigation Alignment Guides. Instruments facilitate positioning of implants and marking of bone. Modification involves updated sterilization instructions allowing use of FDA-cleared containment devices. Instruments are placed in containment devices, wrapped in medical-grade material, and steam sterilized. Used in clinical settings by surgeons. Benefits include standardized, validated reprocessing workflow for surgical instruments.

Clinical Evidence

No clinical or animal testing was required. Evidence consists of bench testing, including steam sterilization validation per AAMI ST77:2013 and AAMI ST79:2017, and vibration testing per ISTA 2A.

Technological Characteristics

Non-sterile orthopedic surgical instruments. Modification involves steam sterilization process using FDA-cleared containment devices (single-level and double-level trays). Validated per AAMI ST77:2013 and AAMI ST79:2017. Mechanical integrity verified via ISTA 2A vibration testing.

Indications for Use

Indicated for skeletally mature patients undergoing knee arthroplasty for noninflammatory degenerative joint disease (osteoarthritis, traumatic arthritis, avascular necrosis), inflammatory degenerative joint disease (rheumatoid arthritis), functional deformity correction, revision procedures, or fracture treatment.

Regulatory Classification

Identification

A knee joint patellofemorotibial metal/polymer porous-coated uncemented 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 is designed to achieve biological fixation to bone without the use of bone cement. This identification includes fixed-bearing knee prostheses where the ultra high molecular weight polyethylene tibial bearing is rigidly secured to the metal tibial base plate.

Special Controls

*Classification.* Class II (special controls). The special control is FDA's guidance: “Class II Special Controls Guidance Document: Knee Joint Patellofemorotibial and Femorotibial Metal/Polymer Porous-Coated Uncemented Prostheses; Guidance for Industry and FDA.” See § 888.1 for the availability of this guidance.

Device Description The device modification consists of an alteration to the sterilization instructions for FDAcleared MicroPort Orthopedics' (MPO) non-sterile knee orthopedic joint replacement instruments. The subject instruments are part of MicroPort Orthopedics' 510(k)-cleared knee product lines and are required to facilitate total knee arthroplasty procedures. The modification will allow the option to sterilize the subject instruments using an FDA-cleared containment device. The subject devices will be placed in an FDA-cleared containment device, which will be double-wrapped in an FDA-cleared CSR wrap or similar type nonwoven, medical grade wrapping material, and then steam sterilized. The modified sterilization process of the subject instruments was successfully challenged and validated through worst-case load configurations using an FDA-cleared containment device. The intended use and sterilization parameters, such as cycle, temperature, and exposure time, remain identical to the predicate devices. #### B. Intended Use MicroPort knee instruments are accessory devices and are intended to be used to assist in the implantation of MicroPort Knee Systems in their cleared Indications for Use as provided below: MicroPort Total Knee Systems are indicated for use in knee arthroplasty in skeletally mature patients with the following conditions: - 1) noninflammatory degenerative joint disease including osteoarthritis, traumatic arthritis, or avascular necrosis; - 2) inflammatory degenerative joint disease including rheumatoid arthritis; - 3) correction of functional deformity; - 4) revision procedures where other treatments or devices have failed; and treatment of fractures that are unmanageable using other techniques. Non-porous MicroPort total knee replacement implants are for cemented use only. Porous coated MicroPort total knee replacement implants, including ADVANCE® BIOFOAM® Tibial System and EVOLUTION® BIOFOAM® Tibial System implants, are for use without bone cement.

The PROPHECY® Pre-Operative Navigation Alignment Guides are intended for use with MicroPort's ADVANCE® and EVOLUTION® Total Knee Systems and their cleared indications for use, provided that anatomic landmarks necessary for alignment and positioning of the implant are identifiable on patient imaging scans. The PROPHECY® Pre-Operative Navigation Alignment Guides are intended for single use only. # C. Technological Characteristics Comparison MicroPort subject non-sterile knee orthopedic joint replacement instruments were successfully validated and sterilized using an FDA-cleared containment device. MicroPort non-sterile orthopedic joint replacement instruments are able to withstand the reported sterilization cycles and achieve sufficient device sterility. # D. Nonclinical Testing Provided below is a summary table of the non-clinical testing that were performed using the subject device. The result demonstrated that the subject device nonclinical test results met the acceptance criteria of the standards. - Steam Sterilization Validation of MicroPort orthopedic joint replacement instruments ● using FDA-cleared containment device (single-level tray) per AAMI ST77:2013 - Steam Sterilization Validation of MicroPort orthopedic joint replacement instruments ● using FDA-cleared containment device (double-level tray) per AAMI ST79:2017 - Vibration Test of MicroPort orthopedic joint replacement instruments using FDA-● cleared containment device per ISTA 2A. ## E. Clinical and Animal Testing No clinical or animal testing were required. ## F. Conclusions The sterilization of the subject devices is substantially equivalent to the predicate devices. The safety and effectiveness of the modified sterilization method of the subject devices is adequately supported by the substantial equivalence information, materials information, and design control summaries data provided within this Premarket Notification. Validation testing and analysis data adequately support the substantial equivalence of MPO Knee Instruments Reprocessing Change.
