Indications for Use
The MAKO Modular Knee Compartmental Implant System is indicated for single or multi-compartmental knee replacement used in conjunction with the MAKO Tactile Guidance System in individuals with osteoarthritis or post traumatic arthritis of the medial tibiofemoral and/or patellofemoral articular surfaces. The MAKO Modular Knee Compartmental Implant System is for single use only and is intended for implantation with bone cement.
Device Story
MMKC is a modular knee implant system comprising unicompartmental (MMKC-Uni) and patellofemoral (MMKC-PF) components. Used for medial tibiofemoral and/or patellofemoral replacement. System requires use with MAKO Tactile Guidance System (TGS) for surgical implantation. Components include femoral, tibial inlay, tibial onlay, tibial baseplate, and patellar implants in various sizes. Materials include CoCr, UHMWPE, and Ti6Al4V. Instrumentation (sizers, templates, trials, drills, etc.) provided in reusable trays. Device is implanted by surgeons in an OR setting using bone cement. TGS provides tactile guidance to assist in precise component placement. Benefits include restoration of joint function in patients with degenerative or post-traumatic arthritis.
Clinical Evidence
No clinical data provided. Substantial equivalence is based on bench testing, material biocompatibility per ASTM standards, and design comparison to legally marketed predicate devices.
Technological Characteristics
Materials: CoCr (femoral/patellofemoral), UHMWPE (inlay/onlay/patella), Ti6Al4V (baseplate), Titanium wire (marker). Components: Modular femoral, tibial, and patellar implants. Sterilization: Gamma radiation for implants; steam for instrumentation. Connectivity: Requires integration with MAKO Tactile Guidance System (TGS). Biocompatibility: Compliant with recognized ASTM standards.
Indications for Use
Indicated for individuals with osteoarthritis or post-traumatic arthritis of the medial tibiofemoral and/or patellofemoral articular surfaces requiring single or multi-compartmental knee replacement. Intended for use with bone cement.
Regulatory Classification
Identification
A knee joint femorotibial metal/polymer non-constrained cemented prosthesis is a device intended to be implanted to replace part of a knee joint. The device limits minimally (less than normal anatomic constraints) translation in one or more planes. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral condylar resurfacing component or components made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components made of ultra-high molecular weight polyethylene and are intended for use with bone cement (§ 888.3027).

Description: The MMKC is composed of a unicompartmental implant system (MMKC-Uni) and a PF implant system (MMKC-PF). MMKC-Uni and MMKC-PF may be used in various combinations to create: a single unicompartmental femorotibial replacement for the medial side of the knee; a patellofemoral replacement; or a bicompartmental patellofemorotibial replacement for the medial side of the knee. MMKC-UNI is designed for use when load bearing ROM is expected to be less than or equal to 155 degrees.
