A hinged knee brace is a medical device that supports and stabilizes the knee joint. It features rigid supports, often made of metal or plastic, on either side of the knee. These supports connect via a hinge mechanism that aligns with the knee’s natural axis of rotation. Its primary function is to provide external support, helping to stabilize the knee.
Providing Stability and Controlled Movement
Hinged knee braces offer stability by mimicking the knee’s natural movement while limiting unwanted motion. The hinges allow for normal bending and straightening of the leg (flexion and extension). They also prevent excessive movement in harmful directions, such as hyperextension (bending too far backward) or unnatural side-to-side movements (valgus or varus stress), which can strain ligaments.
The brace’s rigid uprights work with the hinges to provide controlled support. These bars run along the thigh and shin, applying pressure to the knee to prevent deviations and buckling. This external framework helps maintain proper knee alignment, reducing stress on injured ligaments and cartilage. By guiding the knee through a safe range of motion, the brace protects healing tissues and reduces load on compromised areas.
Common Applications
Hinged knee braces are frequently used to support knee health and recovery. They are often recommended for ligament injuries, such as tears to the ACL, MCL, or PCL. The brace provides stability, allowing injured ligaments to heal while preventing re-injury. For example, after an ACL injury, it stabilizes the joint and prevents excessive twisting or hyperextension.
These braces are also used during post-surgical rehabilitation, offering controlled support as the knee recovers. They allow for gradual increases in range of motion while protecting the surgical site. For osteoarthritis, a hinged brace can stabilize the joint and reduce pressure, alleviating pain. Athletes in high-impact activities or contact sports may use them to prevent injury or re-injury, as they provide robust stability during dynamic movements.
Broader Advantages and Professional Guidance
Beyond mechanical stability, hinged knee braces offer several other benefits. They can reduce pain by limiting painful movements and distributing pressure evenly across the knee joint. This stability and pain relief can increase confidence during daily activities. A brace also protects against further injury, especially when returning to activities after healing.
Hinged knee braces are medical devices, and their proper selection and fitting are important for effectiveness and safety. Consulting a healthcare professional (doctor, physical therapist, or orthotist) is advisable before use. Experts assess the condition, recommend support, and ensure correct fitting. A well-fitted brace is crucial to ensure it functions as intended and avoids issues like skin irritation or inadequate support.
