• Submission Type: Special
• Regulation: 21 CFR 888.3560
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

1) Painful and disabled knee joint resulting from osteoarthritis, rheumatoid arthritis, traumatic arthritis where one or more compartments are involved, Failure of previous joint replacement procedure, 2) 3) Correction of varus, valgus, or posttraumatic deformity. 4) Correction or revision of unsuccessful osteotomy or arthrodesis Device designed for use in patients with metal sensitivity. . Standard surgical and rehabilitative procedures are indicated with this device. . The device is a single use device intended for use with bone cement. .

Device Story

Titanium femoral knee components (Maxim and AGC systems) for total knee arthroplasty; intended for patients with metal sensitivity. Device consists of Ti-6Al-4V alloy femoral components treated with nitrogen ion implantation. Used in surgical settings by orthopedic surgeons; implanted via bone cement. Provides structural replacement for damaged knee joint surfaces; restores joint function; corrects deformities. Modification from predicate limited to change in vendor for nitrogen ion implantation process; design, materials, and sizing remain identical to predicate.

Clinical Evidence

No clinical data provided; substantial equivalence based on non-clinical laboratory testing.

Technological Characteristics

Material: Ti-6Al-4V alloy. Surface treatment: Nitrogen ion implantation. Form factor: Femoral knee components (Maxim and AGC). Fixation: Cemented. Single-use. No software or electronic components.

Indications for Use

Indicated for patients with painful/disabled knee joints due to osteoarthritis, rheumatoid arthritis, or traumatic arthritis; failure of previous joint replacement; or need for correction of varus, valgus, posttraumatic deformity, or failed osteotomy/arthrodesis. Suitable for patients with metal sensitivity. Single-use only; requires bone cement.

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).
