ACL reconstruction surgery
Back

ACL Reconstruction Surgery is a procedure to replace a torn anterior cruciate ligament (ACL) in the knee. The ACL is a crucial ligament that helps stabilize the knee joint, often damaged due to sports injuries or accidents. In this surgery, a graft (typically taken from the patient's own tendon or from a donor) is used to replace the damaged ligament. The surgery is performed arthroscopically, using small incisions and a camera for guidance. The goal is to restore knee stability, allowing the patient to return to physical activities and sports after a period of recovery and rehabilitation.

Who Need ACR Reconstriction Surgery

ACL reconstruction surgery is commonly performed on individuals who have suffered a torn or ruptured anterior cruciate ligament (ACL), often due to sports injuries or trauma. Conditions that typically require this procedure include:

  • Complete ACL tears
  • Partial ACL tears with instability
  • Sports-related knee injuries (e.g., football, basketball, skiing)
  • ACL injuries combined with other ligament or meniscus damage
  • Chronic knee instability or repeated giving way

Key Takeaways

  • Type of Procedure: Minimally invasive surgical procedure using arthroscopy
  • Duration: Typically takes 1 to 2 hours, depending on the complexity of the injury.
  • Anesthesia Used: General anesthesia is commonly used. In some cases, regional anesthesia (such as spinal or epidural) may be used.
  • Recovery Time: Initial recovery typically takes 2 to 3 weeks to regain basic mobility. Full recovery and return to sports can take anywhere from 6 to 9 months, depending on the progress of rehabilitation.
  • Indication of ACL Reconstruction Surgery

    ACL (anterior cruciate ligament) reconstruction surgery is typically recommended for individuals with significant knee instability due to a torn ACL. Common indications include:

    • Complete ACL Tear: Confirmed by MRI or clinical tests and causing knee instability.
    • Persistent Knee Instability: Recurrent episodes of the knee "giving way," especially during sports or daily activities.
    • Active Lifestyle: Individuals who wish to return to sports or physically demanding jobs that involve pivoting, jumping, or quick directional changes.
    • Associated Knee Injuries: Presence of additional injuries such as meniscal tears, cartilage damage, or ligament injuries that may worsen without surgical intervention.
    • Failure of Non-Surgical Treatments: When physical therapy and bracing do not provide adequate knee stability.
    • Young Age: Younger patients involved in high-impact activities often benefit from surgery to prevent long-term joint damage.

    ACL reconstruction helps restore knee stability, prevent further joint damage, and enable return to physical activities safely.

    Preparing for ACL Reconstruction Surgery

    • Consultation with Your Surgeon: Discuss the procedure, risks, and recovery plan in detail. Address all your questions and concerns.
    • Medical Evaluation: Undergo required tests, such as X-rays or MRI scans, to assess the extent of the injury.
    • Pre-Surgery Exercises: Strengthen your leg muscles through prescribed exercises to improve post-surgery recovery.
    • Medications: Inform your doctor about any medications you are taking, as some may need to be adjusted or stopped before surgery.
    • Stop Smoking and Alcohol: Avoid smoking and alcohol, as they can hinder healing and increase complications.
    • Fasting: Follow fasting instructions (usually 6-8 hours) before surgery to ensure safety during anaesthesia.
    • Home Preparation: Arrange for mobility aids like crutches and set up a comfortable recovery area at home.
    • Transportation and Assistance: Plan for someone to drive you to and from the hospital and assist you during the initial recovery days.
    • Mental Readiness: Stay informed and mentally prepared for the procedure and the recovery process ahead.

    ACL Reconstruction Surgery Procedure

    • Anesthesia Administration: General or regional anaesthesia is used to keep the patient comfortable and pain-free throughout surgery.
    • Arthroscopic Examination: A small camera (arthroscope) is inserted through tiny incisions to inspect the knee joint and confirm the extent of damage.
    • Removal of Torn ACL: The damaged ligament is carefully removed using surgical tools through additional small incisions.
    • Graft Harvesting: A tendon graft, often from the patient's hamstring or patellar tendon, is prepared to replace the torn ACL.
    • Graft Placement: The graft is introduced into the knee and carefully positioned via small holes drilled into the thigh bone (femur) and shinbone (tibia).
    • Fixation: The graft is held in place with screws or other fixing devices to ensure stability during the healing phase.
    • Closure: Sutures or staples are used to close the small incisions, followed by a sterile dressing.
    • Postoperative Stabilization: A knee brace or bandage is used to immobilize and protect the knee immediately after surgery.
    • Monitoring and Recovery: The patient is moved to the recovery room for monitoring before being discharged with detailed post-surgery care instructions.

    Common Complications After ACL Surgery

    • Infection: Rare, but possible at the incision sites.
    • Blood Clots: Can form in the legs, leading to swelling or pain.
    • Knee Stiffness: Difficulty straightening the knee.
    • Graft Failure: The graft may fail to heal properly or become loose.
    • Nerve Damage: In rare cases, nerves can be injured.
    • Swelling and Pain: Swelling may persist beyond the normal recovery period.
    • Scar Tissue: Excessive scarring may limit knee movement.

    ACL Reconstruction Surgery Recovery Time

    • First two weeks: Use crutches and a brace to control pain, reduce swelling, and re-establish fundamental knee movement.
    • Weeks 3-6: Start physical therapy to enhance range of motion, strength, and stability.
    • 3 to 6 months: Gradually resume non-contact activities and sports-specific training.
    • 6 to 9 months: Complete recovery for high-impact sports, depending on strength and knee stability tests.

    Strict devotion to physiotherapy and follow-ups leads to a smoother recovery.

    Precautions After ACL Reconstruction Surgery

    • Rest and Elevate: Rest your knee and keep it elevated to reduce swelling.
    • Pain Management: Take prescribed pain medications as directed.
    • Use Crutches and Brace: Use crutches to avoid putting weight on the knee and wear a knee brace for support.
    • Avoid Stress on Knee: Don't put too much weight on the operated leg during the first few weeks.
    • Follow Physical Therapy: Do your exercises to regain strength and movement.
    • Avoid Strenuous Activities: No running or intense exercises until cleared by your doctor.
    • Watch for Infection: Keep an eye on any signs of infection, like redness or drainage.
    • Healthy Diet: Eat well to support healing and tissue recovery.
    • Gradual Return to Activities: Slowly increase activity levels as your doctor advises.
    • Follow-Up Visits: Keep all doctor appointments to track progress.
