PCL Reconstruction

A PCL injury can make even simple movements feel unstable. If your knee feels weak, wobbly, or painful after a fall or impact, your posterior cruciate ligament (PCL) may be damaged. Unlike the ACL, which is often injured in sudden twisting motions, the PCL is usually torn by direct force—like a car accident or a hard fall onto a bent knee.

If left untreated, a torn PCL can lead to long-term knee instability, weakness, and even arthritis. For severe injuries, PCL reconstruction surgery can restore strength, helping you return to daily activities or sports without pain or instability.

Dr. David Sime, a highly experienced orthopaedic specialist, performs PCL reconstruction in Melbourne, using advanced techniques to rebuild the ligament and stabilise the knee.

What Is PCL Reconstruction?

The posterior cruciate ligament is one of the four major ligaments in the knee. It sits at the back of the joint and prevents the shinbone from shifting backward. When it’s torn, the knee can become unstable, affecting balance, strength, and movement.

PCL reconstruction surgery replaces the damaged ligament with a graft—usually from your own body or a donor tendon. The goal is to rebuild the knee’s support system, so you can move without pain or fear of it giving way.

During PCL surgery, Dr. Sime:

• Uses arthroscopy knee surgery to examine the damage and clean up the joint.

• Removes the torn ligament and prepares the area for the graft.

• Secures a healthy tendon in place, allowing it to heal and function as a new ligament.

Most procedures are minimally invasive, which means smaller incisions, faster healing, and less discomfort during recovery.

PCL Replacement

While PCL reconstruction is a common  approach for repairing a torn posterior cruciate ligament, PCL replacement is also a commonly used option. Reconstruction uses a tendon graft to rebuild the ligament, while PCL replacement would involve substitution with an synthetic  implant. In PCL reconstruction surgery,  a well-placed graft provides long-term stability and function, whether tendon or an artificial ligament is decided to be the preferred choice.

Do You Need PCL Reconstruction Surgery?

Not all PCL tears require surgery. Some mild injuries heal with rest, bracing, and physiotherapy. However, PCL reconstruction is often needed if:

• The knee feels unstable, even after rehabilitation.

• The injury is combined with ACL reconstruction surgery or damage to other knee structures.

• The ligament is completely torn and unlikely to heal on its own.

• You experience persistent pain or difficulty walking, climbing stairs, or exercising.

Leaving a PCL tear untreated may lead to long-term issues, including arthritis and ongoing knee instability. If the knee remains unstable after a PCL tear, additional procedures like knee alignment surgery may be recommended to improve joint positioning and function.

What Happens During PCL Surgery?

Dr. Sime’s approach to PCL reconstruction in Melbourne ensures precision and a personalised treatment plan for every patient. The procedure generally includes:

• Arthroscopy knee surgery: To assess and clean the joint.

• Tendon grafting: A healthy tendon is used to replace the damaged PCL.

• Bone tunnel creation: Small holes are drilled to secure the graft in place.

• Stabilisation and healing: The knee is carefully positioned for proper recovery.

The procedure typically takes 1-2 hours, and most patients return home the same day. For patients who have experienced multiple kneecap dislocations along with a PCL injury, patellar dislocation treatment may also be necessary to restore full knee stability.

Recovery After PCL Reconstruction Surgery

Healing from PCL surgery takes time, but a structured rehabilitation program will help you regain strength.

What to expect during recovery:

• First few weeks: Crutches to support healing and mobilisation.

• 4–6 weeks: Gradual introduction of mobility exercises with physiotherapy.

• 3–6 months: Strength-building exercises to restore function.

• 6–12 months: Return to full activity, including sports, with medical clearance.

Rehabilitation is key—the stronger the knee becomes, the better the long-term outcome. Dr. Sime and his team provide a customised plan to ensure a safe and effective recovery.
