Indications for Use
The MAKO Surgical Unicondylar Knee is a single use device intended for cemented reconstruction of the medial or lateral femur and corresponding tibial surface of moderately disabled and/or painful knee resulting from osteoarthritis, traumatic arthritis provided there is evidence of sufficient bone to seat the implant. Indications for use include moderate joint impairment from painful arthritis (osteo and/or post-traumatic), and as an alternative to tibial osteotomy in patients with unicompartmental arthritis.
Device Story
MAKO Surgical Unicondylar Knee System is a cemented, single-use knee prosthesis; replaces medial or lateral femorotibial surfaces. Components include CoCr femoral component and UHMWPE tibial component with radiographic marker pin. System includes manual surgical instrumentation (sizers, templates, trials, drills, impactors) for implantation. Used by surgeons in clinical settings for patients with moderate joint impairment from arthritis. Provides mechanical reconstruction of the knee joint; restores joint function; alleviates pain associated with unicompartmental arthritis.
Clinical Evidence
Bench testing only. No clinical data provided.
Technological Characteristics
Materials: Femoral component (CoCr per ASTM F-75), Tibial component (UHMWPE per ASTM F-648 Type 2), Radiographic marker (Titanium wire per ASTM F-1341). Design: Non-constrained, cemented, metal/polymer femorotibial prosthesis. Congruency: 20-27%. Sterilization: Gamma radiation for implants; prevacuum steam for instrumentation. Packaging: Double sterile barriers; tibial component in Argon gas.
Indications for Use
Indicated for patients with moderate joint impairment from painful osteoarthritis or post-traumatic arthritis requiring cemented reconstruction of the medial or lateral femur and corresponding tibial surface; alternative to tibial osteotomy for unicompartmental arthritis; requires sufficient bone stock to seat the implant.
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).
