Ottobock Liner and Below-Knee Prosthetic Leg Analysis Report

Device Identification

The examined images contain two main orthopedic/prosthetic components. The first component is a modular below-knee (transtibial) prosthetic leg with a cosmetic foam covering, including the foot and calf sections. The second component is a prosthetic liner product, which is a soft tissue interface used between the residual limb and the socket.

Brand and Model Information

Based on the data obtained from the images, the brand and model analysis is as follows:

• Prosthetic Liner (Image 2): A white Ottobock logo, vertically positioned on the outer surface of the product, is clearly legible. Characteristic graphic patterns belonging to the brand are located directly below the logo.
• Below-Knee Prosthetic Leg (Image 1): No logo, brand label, or model name is present on this component. Therefore, no definitive data regarding the brand of the leg module has been provided.

Areas of Use

These products are used in orthopedic rehabilitation and prosthetic applications. The Ottobock liner is used to protect the amputated limb (residual limb), prevent friction between the prosthetic socket and the skin, and provide suspension (the prosthesis’s attachment to the body). The cosmetically covered prosthetic leg is designed to restore walking function and provide an anatomical leg appearance for patients who have undergone a below-knee (transtibial) amputation.

Physical Characteristics and General Condition

Below-Knee Prosthetic Leg:

• Color and Covering: The product is covered with a skin-colored (beige) cosmetic foam. The covering extends from the toes to below the kneecap.
• Surface Details: In the middle of the calf area, a circular protrusion is observed beneath the foam covering. This section likely indicates the location of a mechanical part belonging to an active vacuum valve or suspension system.
• Foot Structure: The foot section is produced in a realistic form with toe details.
• Socket Connection: At the upper part, the rigid socket opening where the residual limb will enter is visible.

Prosthetic Liner:

• Color and Texture: The product appears in a matte white/translucent gray color. Its surface is smooth, giving the impression that it is made from silicone or thermoplastic elastomer (TPE) material.
• Form: It has a conical structure, starting cylindrically and rounding at the distal end (bottom part).

Quantity Information

A total of 2 items are present in the analyzed images:

• 1 cosmetic covered below-knee prosthetic leg.
• 1 Ottobock brand prosthetic liner.

Cosmetic and Mechanical Condition

The condition of both products is as follows:

• Wear and Tear Analysis: Both products are in new or display item condition. No discoloration, sweat stains, or silicone abrasion are observed on the liner. No tears, unravelling, or soiling have been detected on the prosthetic leg’s cosmetic covering.
• Cleanliness: The surfaces are clean. No biological residue or dirt layer due to use is present.
• Deformation: No signs of collapse, warping, or damage compromising integrity have been found in their physical forms.

Accessories and Missing Parts

The original boxes, user manuals, or warranty documents for the products are not included in the images. The prosthetic leg stands as a single assembly; patient-specific connection adapters or in-socket suspension pins are not detailed in the visual.

Conclusion Assessment

The displayed products appear ready for use and clean in terms of condition. The brand recognition of the Ottobock-branded liner has been confirmed. The below-knee prosthesis is a medical device with a completed cosmetic covering, no apparent mechanical issues, and preserved aesthetic integrity. There are no signs of significant wear or damage.
