Intended Use

The Freedom® Ultra-Congruent CR Tibial Liner consists of an ultra-high molecular weight polyethylene (UHMWPE) liner that is designed to be used with the Freedom® Total Knee Cruciate Retaining (CR) Femoral Components in the Freedom® Total Knee System. The Freedom® Total Knee System is indicated for the following: - Severe knee joint pain, loss of mobility, and disability due to: rheumatoid arthritis, osteoarthritis, traumatic arthritis, and polyarthritis. - Correction of functional deformities. - Post-traumatic loss of knee join contour, particularly when there is patellofemoral erosion, dysfunction, and/or prior patellectomy. - Moderate valgus, varus, or flexion trauma. - Knee fractures untreatable by other methods. The Freedom® Ultra-Congruent Tibial Liner is intended for cemented use only. This device is for single use only.

Device Story

Freedom Ultra-Congruent CR Tibial Liner is a UHMWPE component of the Freedom Total Knee System; designed for use with Freedom Total Knee CR Femoral Components. Device functions as a bearing surface in total knee arthroplasty; provides stability and articulation in patients requiring joint replacement due to arthritis, deformity, or trauma. Used in clinical settings by orthopedic surgeons; implanted via cemented fixation. Benefits include restoration of knee function, pain relief, and correction of deformities. Device is single-use.

Clinical Evidence

No clinical data provided; substantial equivalence based on bench testing.

Technological Characteristics

Material: Ultra-high molecular weight polyethylene (UHMWPE). Design: Ultra-congruent tibial liner for cruciate-retaining (CR) applications. Fixation: Cemented. Sterilization: Not specified. Connectivity: None. Software: None.

Indications for Use

Indicated for patients with severe knee joint pain, loss of mobility, and disability due to rheumatoid, osteoarthritis, traumatic arthritis, or polyarthritis; functional deformities; post-traumatic loss of knee joint contour with patellofemoral erosion/dysfunction/prior patellectomy; moderate valgus, varus, or flexion trauma; or knee fractures untreatable by other methods. Intended for 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).
