Guide price only. Final cost is confirmed after assessment.

Anterior cruciate ligament (ACL) reconstruction is a surgical procedure to fix a tear in the ACL ligament in your knee. During the surgery, the torn ligament is replaced with a tissue graft of a tendon from another area of your knee. Not every individual who has an ACL injury will need ACL reconstruction surgery, but it can make a significant difference to your activity level and daily life if it is the right treatment option for you. Our specialists will be able to discuss with you whether surgery might be needed during your consultation.

ACL reconstruction step by step

ACL reconstruction is usually performed arthroscopically through small incisions. A camera and precision instruments are used to prepare the knee and position the graft.

  • Graft selection (commonly hamstring or patellar tendon) based on your profile.
  • Bone tunnels are created in femur and tibia for accurate graft placement.
  • Fixation is secured, then tension and knee motion are checked before closure.

Typical operative time is around 1 to 3 hours, followed by a structured rehabilitation programme that is as important as the surgery itself.

Frequently Asked Questions

What is recovery like from ACL reconstruction?

Full ACL reconstruction recovery can take around six months to a year with exact times varying from patient to patient. During your recovery you should see a physiotherapist who will provide a tailored rehabilitation programme featuring exercises that allows you to gain full strength and range of motion in the knee. Before returning to sport as normal, the physiotherapist will want to check that you are both mentally and physically ready.

How do ACL injuries occur?

ACL injuries are some of the most common types of knee injury and often occur doing sports like tennis, squash, skiing, football, and rugby. The ACL can tear if your lower leg is extended too far forward or if your knee/lower leg is twisted. This can be done by landing from a jump incorrectly, stopping or changing direction suddenly, or colliding with another person (like a football tackle).

What are the signs of a torn ACL?

If your ACL is torn, the knee can lose its full range of movement and will likely become quite unstable. As a result, it can be difficult to complete certain movements like doing a turn on the spot. It might not sound that serious, but a tear in the ACL for some individuals can mean they can no longer play their sport until the issue is resolved with ACL reconstruction.

Bioactive Gels for Natural Cartilage Regrowth and Joint Health

Bioactive gels represent a groundbreaking advancement in cartilage repair, promoting the natural regrowth of durable hyaline cartilage rather than just symptom relief. These gels serve as scaffolds attracting chondrocytes and stem cells to regenerate smooth, shock-absorbing cartilage, offering an innovative alternative to traditional joint injections. Clinical studies demonstrate their efficacy in filling cartilage defects, improving joint function, and reducing pain. Technologies include collagen-based and peptide-based gels that closely mimic natural cartilage matrix, enhancing cellular regeneration. Led by experts like Professor Paul Lee at the London Cartilage Clinic, these treatments combine advanced gel therapies with personalized rehabilitation for optimal outcomes. While ongoing research continues, bioactive gels offer promising long-term solutions for osteoarthritis and cartilage injury patients seeking genuine healing and improved mobility.

Inflamed Meniscus Symptoms and Management in the UK

An inflamed meniscus, a crucial knee cartilage, causes pain, swelling, and stiffness impacting mobility. Common in athletes and older adults, inflammation arises from injury, overuse, or aging. Effective management ranges from rest and physiotherapy to surgery for severe cases. Recent studies link inflammation to osteoarthritis progression and explore molecular mechanisms like microRNAs affecting healing. Early expert assessment ensures accurate diagnosis and personalised treatment. Specialist care, as provided by orthopaedic experts like Professor Paul Lee, supports optimal recovery and pain-free movement. Awareness of symptoms and timely intervention are key to restoring knee function and preventing long-term joint damage.
