Intended Use

The OptiGen™ Total Knee System is indicated for patients with severe knee pain and disability due to: - Rheumatoid arthritis ● - Post-traumatic arthritis, osteoarthritis, or degenerative arthritis ● - Failed osteotomies, unicompartmental replacement, or total knee ● replacement - Moderate varus, valgus, or flexion deformities . This device is indicated for cemented use only.

Device Story

OptiGen™ Total Knee System is a semi-constrained cemented prosthesis for total knee arthroplasty. Components include femoral (PS, CR), tibial, tibial bearing, patellar, and accessory parts (locking bars, cement plugs). Device replaces damaged knee joint surfaces to alleviate pain and restore function in patients with severe arthritis or deformity. Implanted by orthopedic surgeons in a clinical/OR setting using bone cement. System design, materials, and mechanical performance are intended to mimic established total knee systems. Benefits include improved joint mobility and pain reduction.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included static tests (A/P and M/L shear, tensile pull-off, locking bar removal, A/P and M/L draw, I/E rotation, patellofemoral subluxation, tibial tray, post shear, femorotibial and patellofemoral contact) and dynamic tests (tibial tray, post shear).

Technological Characteristics

Semi-constrained cemented prosthesis. Materials: CoCrMo Alloy (ASTM F75) for femoral components; Titanium Alloy (ASTM F136) for tibial components and locking bars; UHMWPE (ASTM F648) for tibial bearings and patellar components. Designed for primary application with bone cement.

Indications for Use

Indicated for patients with severe knee pain and disability due to rheumatoid arthritis, post-traumatic arthritis, osteoarthritis, degenerative arthritis, failed osteotomies, failed unicompartmental/total knee replacement, or moderate varus, valgus, or flexion deformities. Cemented use only.

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).
