Product description

Advanced ligament support designed around natural knee movement

The OssKin Provoke™ Ligament Knee Brace is designed for patients managing torn or deficient knee ligaments, meniscal injury and chronic ligament instability.

Its patented Asymmotion™ hinge system is engineered to follow the knee’s natural three-dimensional movement rather than limiting the joint to simple flexion and extension. This helps provide controlled support while allowing comfortable mobility during walking, work, rehabilitation and approved recreational activity.

The brace uses a lightweight, rigid frame made from high-performance Polyamide 2200, a material used in aerospace and medical manufacturing. OssKin describes the frame as ultra-low-profile, durable and designed to fit close to the leg for discreet wear under loose clothing.

The Provoke features an open-patella and open-popliteal design, rigid double uprights and a supportive hinge configuration intended to protect deficient knee ligaments across the three anatomical planes of movement.

Liberty carries this product in Black, with store options listed as Small, Medium, Large and XL. Professional assessment and fitting are strongly recommended to confirm the correct product, size and clinical suitability.

Key features

Patented Asymmotion™ hinge system

Tracks the knee’s natural three-dimensional movement, including the rotational movement that occurs during bending and straightening.

Ligament support

Designed to support deficient or injured knee ligaments during movement.

Lightweight rigid frame

OssKin reports that the Provoke weighs approximately 10.5 oz, although final weight may vary by configuration.

Low-profile construction

The frame is approximately 7–8 mm thick and designed to fit beneath loose pants or clothing.

Polyamide 2200 material

Constructed from high-performance, aircraft-grade Polyamide 2200 for durability and structural support.

Open-patella design

Leaves the kneecap open and avoids unnecessary pressure directly over the patella.

Open-popliteal design

The back of the knee remains open to help reduce bunching and improve comfort during flexion.

Double-upright support

Rigid medial and lateral uprights help provide controlled knee support.

Designed to minimize migration

The close-fitting design is intended to improve leg tracking and help reduce unwanted brace movement.
