Functions of the Stifle (Knee) Orthosis

The stifle orthosis is designed to provide targeted stabilization of the canine knee joint in cases of ligament injury or joint instability. When the cranial cruciate ligament (CCL) is compromised, abnormal cranial translation and rotation of the tibia relative to the femur can occur, increasing stress on the menisci, articular cartilage, and surrounding soft tissues. At the same time, compensatory overload of the supporting muscle chains may develop.

A properly designed knee brace helps stabilize the stifle joint, limit abnormal tibial movement, and support controlled, functional motion. By improving joint stability and load distribution, the orthosis may contribute to pain reduction and support tissue recovery as part of a comprehensive treatment or rehabilitation plan.

By enabling earlier and more controlled use of the affected limb, a stifle orthosis can help reduce excessive compensatory loading of the contralateral (unaffected) limb. This is clinically relevant, as dogs with unilateral CCL injury are at increased risk of overloading the opposite limb during recovery.

The overall goal of knee orthotic support is to improve joint stability, promote balanced movement, and support long-term musculoskeletal health while minimizing secondary strain associated with altered gait mechanics.

Who Is a Stifle (Knee) Orthosis Intended For?

A stifle orthosis may be considered for dogs requiring stabilization and controlled support of the knee joint in a range of clinical situations, including:

• Cranial cruciate ligament (CCL) injury
  In cases of partial or complete ligament rupture, a knee brace may be used to support joint stability and help limit abnormal movement that could contribute to secondary joint damage.

• Conservative management prior to surgery
  In selected cases of partial ligament injury where surgical intervention is not immediately indicated, a stifle orthosis may support joint stability as part of a conservative treatment approach while clinical decisions are being evaluated.

• Post-operative support during recovery
  Following surgical repair, a knee brace may assist controlled loading of the joint during the healing phase and support a gradual return to functional movement.

• Support of the contralateral limb during rehabilitation
  In dogs recovering from unilateral stifle surgery, orthotic support may be considered to help stabilize and protect the opposite limb during periods of altered weight-bearing.

• Stabilization in patients not suitable for surgery
  For dogs that are not candidates for surgical intervention due to age, concurrent health conditions, or other limiting factors, a stifle orthosis may provide supportive stabilization as part of long-term management.

Each case is individually assessed to determine whether orthotic support is clinically appropriate and aligned with the dog's overall health status, functional needs, and treatment goals.
