Intended Use

The EVOLUTION™ Unicondylar Knee System is indicated for use in knee arthroplasty in skeletally mature patients with the following conditions: 1. non-inflammatory degenerative joint disease: including osteoarthritis, traumatic arthritis, or avascular necrosis 2. correction of functional deformity; ... . . . . . revision procedures where other treatments or devices have failed: and treatment of fractures 3. that are unmanageable using other techniques. The EVOLUTION™ Unicondylar Knee System is indicated for patients with unicompartmental joint disease secondary to the above indications with or without valgus, varus, or flexion deformities where all ligaments are intact. The EVOLUTION™ Unicondylar Knee System is for cemented use only.

Device Story

The EVOLUTION™ Unicondylar Knee System is a cemented, metal/polymer semi-constrained or non-constrained knee prosthesis. It replaces damaged joint surfaces in patients with unicompartmental knee disease. The system consists of cobalt chrome femoral components, titanium alloy tibial bases, and UHMWPE tibial inserts (universal or conforming). It is intended for use by orthopedic surgeons in a clinical/surgical setting. The device restores joint function and corrects deformities by providing a stable, articulating surface. Clinical benefit is derived from pain relief and improved joint mobility in patients with degenerative joint disease or failed prior interventions.

Clinical Evidence

Bench testing only. Evaluation included static stability, contact area, lock detail, femoral component strength, range of motion, and wear testing. Results indicate the system is equivalent to predicates and capable of withstanding expected in vivo loading.

Technological Characteristics

Materials: Cobalt Chrome Alloy (femoral), Titanium Alloy (tibial base), UHMWPE (tibial inserts). Design: Unicondylar knee prosthesis, cemented use only. Components: Femoral (sizes 1-5), Tibial inserts (universal/conforming, sizes 1-5, 8-12mm thickness), Tibial bases (sizes 1-5), All-poly tibial components (universal/conforming, sizes 1-5, 7-12mm thickness).

Indications for Use

Indicated for skeletally mature patients with unicompartmental joint disease secondary to non-inflammatory degenerative joint disease (osteoarthritis, traumatic arthritis, avascular necrosis), functional deformity, failed prior treatments, or unmanageable fractures. Requires intact ligaments. For cemented use only.

Regulatory Classification

Identification

A knee joint femorotibial metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace part of 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 consist of a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).

Intended Use The EVOLUTION™ Unicondylar Knee System is indicated for use in knee arthroplasty in skeletally mature patients with the following conditions: - 1. non-inflammatory degenerative joint disease: including osteoarthritis, traumatic arthritis, or avascular necrosis - 2. correction of functional deformity; ... . . . . . - revision procedures where other treatments or devices have failed: and treatment of fractures 3. that are unmanageable using other techniques. {1}------------------------------------------------ The EVOLUTION™ Unicondylar Knee System is indicated for patients with unicompartmental joint disease secondary to the above indications with or without valgus, varus, or flexion deformities where all ligaments are intact. The EVOLUTION™ Unicondylar Knee System is for cemented use only. #### B. Device Description The design features of the EVOLUTION™ Unicondylar Knee System are summarized below: - . Femoral components manufactured from Cobalt Chrome Alloy - Femoral component sizes 1 5, Resurfacing- or Resection-based . - . Tibial inserts manufactured from UHMWPE - . Tibial insert: Universal, sizes 1 - 5 - Tibial insert: Conforming, sizes 1 5, left and right . - . Tibial component thickness: 8, 9, 10, 11, 12mm - . Tibial bases manufactured from Titanium Alloy - Tibial base sizes 1 – 5, left and right - . All-poly tibial components manufactured from UHMWPE - . All-poly Universal: sizes 1 - 5, left and right - . All-poly Conforming: sizes 1 - 5, left and right - . All-poly tibial component thickness: 7, 8, 9, 10, 11, 12mm The EVOLUTION™ Unicondylar Knee System was evaluated via mechanical testing and engineering analyses; including static stability, contact area, lock detail, femoral component strength, range of motion, and wear testing. A review of these results indicates that the EVOLUTION™ Unicondylar Knee System components are equivalent to predicate devices and are capable of withstanding expected in vivo loading without failure. #### C. Substantial Equivalence Information The indications for use of the EVOLUTION™ Unicondylar Knee System are identical to the previously cleared predicate devices. The design features and materials of the subject devices are substantially equivalent to those of the predicate devices. The fundamental scientific technology of the modified devices has not changed relative to the predicate devices.
