Questions

AI-generated answers, 18 Sep 2026

Written by a language model from registry data. Not verified by deviCERTS or the manufacturer. The registry data above is the record.

  • What types of knee surgeries is the GEMINI SL Total Knee System designed for, and how does its modularity benefit patients?

    The GEMINI SL Total Knee System is designed for total knee arthroplasty, including both primary and revision surgeries. Its modular components allow for customization to fit individual anatomical needs, ensuring better alignment and function. This adaptability supports patients with severe degenerative joint diseases like arthrosis or arthritis, providing tailored structural support and improved mobility.

  • Is the GEMINI SL Total Knee System reusable, or is it intended for single-use in the operating room?

    The GEMINI SL Total Knee System is explicitly sterile and intended for single-use in surgical settings. This aligns with standard orthopedic implant protocols to ensure patient safety and sterility during procedures.

  • What special coating does the GEMINI SL system feature, and why is it included?

    The system includes the LINK PorEx (TiNbN) inhouse coating, which is applied to enhance biocompatibility and osseointegration—meaning it promotes better bone attachment to the implant. This coating also helps reduce wear, improving long-term performance and durability for patients.

  • How are the components of the GEMINI SL system sized, and can they be used with other LINK knee implants?

    The components come in predefined sizes to match anatomical requirements, ensuring proper fit and function. They are designed to be compatible with the broader LINK SL Knee Family concept, allowing seamless integration with other implants in the same system for consistent surgical planning.

  • What regulatory pathways does the GEMINI SL Total Knee System follow, and what does that mean for its use in the U.S. and EU?

    The system follows FDA 510(k) clearance (K212742) under a Special 510(k) pathway, classified as FDA Class II, and complies with the EU Medical Device Regulation (MDR). This means it has undergone regulatory review for safety and effectiveness in both markets, ensuring it meets stringent standards for orthopedic implants.
