Knee brace for cruciate ligaments
Functional braces to stabilize the knee after a cruciate ligament rupture, whether for conservative treatment or post-surgical protection.
Cruciate ligament injuries
The cruciate ligaments, located at the center of the knee, are essential to joint stability. The anterior cruciate ligament (ACL) prevents the tibia from sliding forward, while the posterior cruciate ligament (PCL) prevents it from sliding backward. A rupture of either of these ligaments causes significant instability that compromises walking, sports activities, and everyday movements.
ACL rupture is one of the most common sports injuries, often occurring during sudden changes of direction, jump landings, or direct contact. Symptoms include an audible pop at the moment of injury, sharp pain, rapid swelling, and a feeling of knee instability.
The role of the functional brace
The functional cruciate ligament brace is a rigid hinged device that replaces the stabilizing function of the damaged or reconstructed ligament. It controls the anteroposterior and rotational movements of the knee while allowing the flexion and extension needed for daily and sports activities.
This brace plays a crucial role in three clinical contexts: pre-surgically to stabilize the knee while awaiting the procedure, post-surgically to protect the ligament reconstruction during rehabilitation, and as conservative treatment for patients who choose not to undergo surgery.
Our approach
At Marchildon, the assessment for a cruciate ligament brace is a comprehensive process. Your orthotist performs specific stability tests (anterior drawer, Lachman, pivot shift), evaluates your range of motion, and analyzes your gait. They take precise measurements of your thigh, knee, and calf to guarantee an optimal fit.
The brace is then adjusted according to your prescription parameters, including range-of-motion limitation if needed during the post-surgical phase. Regular follow-up allows the brace to be adapted as your recovery evolves.
Our orthotists are members of the Ordre des technologues professionnels du Québec (OTPQ) and the Association des Orthésistes-Prothésistes du Québec (AOPQ).
Frequently asked questions about cruciate ligament braces
When should I wear a brace after an anterior cruciate ligament rupture?
The timing depends on your treatment plan. Pre-surgically, a brace can stabilize your knee while you await the operation. Post-surgically, it protects the reconstruction during rehabilitation. For patients who choose conservative treatment, the functional brace replaces the stability the ligament can no longer provide.
Can I return to sports with a cruciate ligament brace?
Yes, functional cruciate ligament braces are designed to allow a safe return to sport. They provide anteroposterior and rotational stability that compensates for ligament laxity. The return to sport should nonetheless be gradual and approved by your physician and physiotherapist.
What is the difference between an ACL brace and a PCL brace?
Both types of braces aim to stabilize the knee, but they apply their forces in different directions. The ACL brace prevents anterior translation of the tibia, while the PCL brace prevents posterior translation. Your orthotist configures the brace according to your specific diagnosis.
How long should I wear the brace after surgery?
Post-surgically, the brace is generally worn for 6 to 12 months, depending on your surgeon's protocol. Some patients continue to wear it for high-risk sports activities even after complete healing. Your orthotist will adjust the brace as your recovery progresses.
Is the cruciate ligament brace reimbursed by RAMQ?
Yes, physician-prescribed knee braces for cruciate ligaments are eligible for reimbursement by RAMQ, CNESST (workplace accidents), SAAQ (road accidents), and private insurance. Our team guides you through the administrative process.
