The anterior cruciate ligament (ACL) is one of the most commonly injured ligaments of the knee. Approximately 52,000 ACL injuries occur every year in the UK, about half of which need to undergo reconstruction. Most ACL injuries occur during sports, when the knee is subject to twisting, sudden changes in direction, over extension or a direct blow.

Knee instability and its effects

After injury, people will experience different levels of knee instability, which will not only limit activities but may also cause pain and discomfort, and potentially increase the likelihood of degenerative knee arthritis. In recent years, more and more research has shown that early mobilisation and rehabilitation are helpful and effective for ACL injuries. 

Interventions for improving Knee Stability

Treatments for ACL injuries may include surgery or rehabilitation, both are aimed at restoring joint stability. Surgical interventions rebuild static stability by implanting replacement tissue, while rehabilitative interventions reinforce dynamic stability through different approaches:

  • Protection provides external compression or restraint to prevent excessive joint motion.
  • Muscle Strengthening Increase muscle strength of lower extremity to decrease stress on ligaments.
  • Proprioception improves sensory feedback to detect joint motion more accurately.
  • Coordination enhances muscle coordination to improve movement control.

How an Orthopaedic brace helps the healing process

Knee braces mainly provide extra stability for the injured joint during healing. Besides protecting the knee by compressing the surrounding soft tissues or restraining joint motion, a brace can help restore joint dynamic stability by enhancing proprioception. Studies have shown that a knee brace can increase joint proprioception and improve neuromuscular control and functional performance.

Recommended Products

Treatment pathways for ACL injury are aimed at increasing tissue healing and restoring joint stability. According to different grades of instability, different supports are appropriate to the demands of the healing process.
