Intended Use

The MAK OSS Femoral Knee Components are intended for cemented use only.

Device Story

MAK OSS Femoral Knee Components are optional femoral knee components used with the Orthopedic Salvage System (OSS) for total knee replacement. The device includes resurfacing or segmental femoral components that utilize the OSS yoke and axle to limit knee extension and prevent hyperextension. The subject device features a modified locking pin design with reduced diameter and added locking tabs. The device is intended for use by orthopedic surgeons in clinical settings. It is implanted to restore joint function and stability in patients with severe joint disease, trauma, or tumor-related bone loss. The locking pin modification ensures secure component fixation. The device benefits patients by providing a constrained, stable knee joint replacement option.

Clinical Evidence

No clinical data. Substantial equivalence was demonstrated through bench testing (verification of insertion and extraction forces).

Technological Characteristics

Femoral knee components featuring a modified locking pin made of wrought Co-Cr-Mo alloy (ASTM F-1537). The pin is 0.002 inches smaller in diameter than the predicate and includes integrated locking tabs. The system is a constrained, cemented prosthesis (KRO).

Indications for Use

Indicated for patients requiring total knee replacement due to painful/disabled joints from avascular necrosis, osteoarthritis, rheumatoid arthritis, or traumatic arthritis; correction of varus, valgus, or post-traumatic deformity; revision of unsuccessful osteotomy, arthrodesis, or previous joint replacement; ligament deficiencies; tumor resections; treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur; or trauma. When used with the Compress Segmental Femoral Replacement System, indicated for correction/revision of unsuccessful osteotomy, arthrodesis, or previous joint replacement; tumor resections; revision of failed total joint arthroplasty; and trauma.

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).

## Device Description:

The MAK OSS Femoral Knee Components are intended to be used as an optional femoral knee component for use in coniunction with the cleared Orthopedic Salvage System. The MAK OSS Femoral Knee Components include either resurfacing or segmental femoral components that utilize the yoke and axle of the OSS System but limit extension of the knee to limit or prevent hyperextension.

## Intended Use:

The MAK OSS Femoral Knee Components are intended for cemented use only.

# Indications For Use:

Biomet's MAK OSS Femoral Knee Components are intended for use in conjunction with the OSS System for total knee replacement procedures. Specific indications for the OSS System are:

- 1. Painful and disabled joint resulting from avascular necrosis, osteoarthritis, rheumatoid arthritis, or traumatic arthritis.
- 2. Correction of varus, valgus or post-traumatic deformity.
- 3. Correction or revision of unsuccessful osteotomy, arthrodesis, or previous joint replacement.
- 4. Ligament deficiencies.
- 5. Tumor resections.
- 6. Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement, unmanageable by other techniques. *
- 7. Revision of previously failed total joint arthroplasty.
- 8. Trauma.

These devices are to be used with bone cement unless a proximal femur is indicated for use (USA).

*Not applicable to Regenerex Ultra Porous Construct titanium knee augment usage (not licensed in Canada), or any other knee component.

When components of the Orthopedic Salvage System are used with Biomet's Compress Segmental Femoral Replacement System, they are intended for uncemented application and indicated for:

- I. Correction or revision of unsuccessful osteotomy, arthrodesis, or previous joint replacement.
- 2. Tumor resections.
- 3. Revision of previously failed total joint arthroplasty.
- 4. Trauma.

## Proposed Change(s):

This Traditional 510(k) is being submitted for design modifications made to the cleared Biomet MAK OSS Femoral Knee Components locking pin.

## Technological Characteristics:

The modified MAK OSS locking pin is manufactured from the same wrought Co-Cr-Mo alloy conforming to ASTM F-1537 as the predicate MAK OSS locking pin. The pin diameter has been reduced by 0.002 inches and is longer than the predicate pin. It incorporates tabs to lock the pin in place. No other changes to the MAK OSS components are proposed by this submission. The intended use and the indications for use are identical to the predicate Systems.

{2}------------------------------------------------

# Non-Clinical Testing:

Verification testing was conducted to demonstrate that the design modification made to the locking pin would not adversely affect the insertion or extraction of the locking pin. The testing demonstrated that the locking pins could be easily inserted and still maintained adequate extraction force.

# Clinical Testing:

Clinical testing was not required to demonstrate substantial equivalence of the design modifications proposed to the cleared predicate devices.
