Intended Use

1. Painful and disabled knee joint resulting from avascular necrosis, osteoarthritis, rheumatoid arthritis, or traumatic arthritis. 2. Correction of varus, valgus or posttraumatic deformity. 3. Correction or revision of unsuccessful osteotomy, arthrodesis, or failure of previous joint replacement. 4. Ligament deficiencies. 5. Tumor resection. 6.

Device Story

OSS 9cm Cobalt Chrome Tibial Bodies are orthopedic implants used in knee joint reconstruction and salvage procedures. The device serves as a structural component in the Orthopedic Salvage System (OSS). It is surgically implanted by an orthopedic surgeon in a clinical/hospital setting to replace or augment bone segments during revision arthroplasty, tumor resection, or trauma management. The device provides mechanical stability to the knee joint. It is intended for use with bone cement. The primary modification from the predicate is the material change from Ti-6Al-4V titanium alloy to Co-Cr-Mo cobalt chrome alloy.

Clinical Evidence

No clinical data was considered necessary to establish substantial equivalence.

Technological Characteristics

Material: Co-Cr-Mo cobalt chrome alloy. Form factor: 9cm resection tibial body. Fixation: Cemented. The device is a component of the Orthopedic Salvage System.

Indications for Use

Indicated for patients with painful/disabled knee joints due to avascular necrosis, osteoarthritis, rheumatoid arthritis, or traumatic arthritis; varus, valgus, or posttraumatic deformity; failed osteotomy, arthrodesis, or joint replacement; ligament deficiencies; tumor resection; non-unions; or femoral neck/trochanteric fractures. Contraindicated for use without bone cement unless a proximal femur is indicated.

Regulatory Classification

Identification

A knee joint femorotibial metal/polymer constrained cemented prosthesis is a device intended to be implanted to replace part of a knee joint. The device limits translation or rotation in one or more planes and has components that are linked together or affined. This generic type of device includes prostheses composed of a ball-and-socket joint located between a stemmed femoral and a stemmed tibial component and a runner and track joint between each pair of femoral and tibial condyles. The ball-and-socket joint is composed of a ball at the head of a column rising from the stemmed tibial component. The ball, the column, the tibial plateau, and the stem for fixation of the tibial component are made of an alloy, such as cobalt-chromium-molybdenum. The ball of the tibial component is held within the socket of the femoral component by the femoral component's flat outer surface. The flat outer surface of the tibial component abuts both a reciprocal flat surface within the cavity of the femoral component and flanges on the femoral component designed to prevent distal displacement. The stem of the femoral component is made of an alloy, such as cobalt-chromium-molybdenum, but the socket of the component is made of ultra-high molecular weight polyethylene. The femoral component has metallic runners which align with the ultra-high molecular weight polyethylene tracks that press-fit into the metallic tibial component. The generic class also includes devices whose upper and lower components are linked with a solid bolt passing through a journal bearing of greater radius, permitting some rotation in the transverse plane, a minimal arc of abduction/adduction. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).

Dear Mr. Baker:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
