Reconstruction of the Anterior Cruciate Ligament (ACL) | PAX Medicus Medical Tourism UK

Posterior Cruciate Ligament (PCL) Reconstruction

The posterior cruciate ligament (PCL) is one of the major stabilising ligaments of the knee. When it is damaged, the joint can become unstable, painful and prone to degenerative changes.

Pax Medicus, as a medical tourism agency, coordinates access to specialist orthopaedic centres offering modern arthroscopic PCL reconstruction and structured rehabilitation pathways.

Understanding the Posterior Cruciate Ligament (PCL)

The posterior cruciate ligament is located behind the ACL and plays a key role in stabilising the knee joint. It prevents excessive backward movement of the tibia in relation to the femur and works with the ACL to control rotational stability

  • Restricts backward movement of the tibia.
  • Supports rotational control of the knee.
  • Keeps knee alignment stable during movement.
  • Protects cartilage and menisci during walking and sport.

Diagnosis of PCL Tears

Diagnosing a PCL injury requires a combination of clinical tests and imaging. Early diagnosis is important to prevent long-term instability and degeneration.

Clinical assessment

  • Detailed medical interview about injury mechanism.
  • Posterior drawer test at 90° of knee flexion.
  • Assessment of tibial sag sign, knee alignment and ligament laxity.

Imaging

  • MRI – gold standard to evaluate PCL, cartilage and menisci.
  • Ultrasound for soft tissue and joint fluid assessment.
  • X-ray to rule out fractures or tibial plateau injuries.

What Is a PCL Injury?

Isolated PCL injuries are less common than ACL injuries. They often occur through high-energy trauma or in combination with other ligament or cartilage injuries. Athletes in contact sports are particularly at risk.

How PCL injuries happen

  • Direct impact to the shin below the knee (“dashboard injury”).
  • Hyperextension of the knee.
  • Falling onto a foot in strong plantarflexion.
  • Combined ACL + PCL tears during high-energy trauma.

Consequences of PCL rupture

  • Knee instability and “giving way”.
  • Abnormal tibia- femur alignment.
  • Excessive external rotation of the tibia.
  • Accelerated cartilage wear and early degenerative changes due to improper load distribution.

Symptoms

  • Pain and swelling.
  • Instability during walking and descending stairs.
  • Reduced confidence in the knee.
  • Sensation that the knee may give way.

When Is PCL Reconstruction Recommended?

Arthroscopic PCL reconstruction is recommended for patients with severe knee instability, combined ligament injuries or significant loss of function.

  • Combined ACL + PCL tears.
  • Tibial plateau fractures or osteochondral injuries.
  • Persistent instability affecting daily activities.
  • Chronic PCL deficiency leading to pain and cartilage overload.
  • Athletes requiring strong knee stability for return to sport.

Without treatment, chronic PCL deficiency can accelerate joint degeneration and lead to early osteoarthritis.

Preparing for PCL Reconstruction

Pre-operative steps

  • Clinical examination and imaging review.
  • Discussion of treatment options and graft type.
  • Anaesthetist consultation and pre-op planning.

Prehabilitation

  • Strengthening muscles that stabilise the knee.
  • Improving circulation and range of motion.
  • Reducing swelling and preventing joint stiffness before surgery.

How PCL Reconstruction Is Performed

PCL reconstruction is carried out arthroscopically under spinal anaesthesia. The minimally invasive technique allows precise reconstruction of the ligament while protecting surrounding structures.

Surgical steps

  • Small incisions for the camera and instruments.
  • Inspection and treatment of all damaged structures.
  • Creation of bone tunnels in the femur and tibia.
  • Placement and fixation of the graft in anatomical PCL positions.

Reconstruction techniques

  • Single-bundle reconstruction – replaces both PCL bundles with one graft.
  • Double-bundle reconstruction – anatomically restores both bundles using two grafts for greater stability.
  • Internal Bracing – preserves the ligament and reinforces it with high-strength tape in recent tears.

Graft materials

  • Autografts – semitendinosus, gracilis or patellar tendon.
  • Allografts – commonly Achilles tendon grafts.
  • Synthetic grafts – increasingly used for selected cases.

Internal bracing provides strong reinforcement, preserves healthy tissue and can significantly speed up recovery when used in the right patients.

Benefits of PCL Reconstruction

PCL reconstruction restores knee stability, reduces chronic pain and helps prevent early degenerative changes. It also improves confidence in walking, sport and daily movement.

  • Better stability and reduction of giving-way episodes.
  • Protection of cartilage and menisci from overload and degeneration.
  • Improved alignment and joint biomechanics.
  • Faster return to activity with structured rehabilitation.

Pax Medicus helps patients access trusted orthopaedic teams, advanced arthroscopic surgery and a fully coordinated treatment pathway through our medical tourism agency.

Recovery After PCL Reconstruction

Rehabilitation after PCL reconstruction is structured and gradual. The goal is to restore knee stability, mobility and strength while protecting the healing graft.

Early recovery

  • Hospital stay typically one day.
  • Knee brace to prevent tibial displacement.
  • Rehabilitation begins on the first day after surgery.
  • Control swelling and protect the graft.

Rehabilitation guidelines

  • Avoid bending the knee beyond 60° during early recovery.
  • No kneeling or crossing legs when sitting.
  • Progressive exercises to restore motion and strength.
  • Supervised physiotherapy for several weeks.

Returning to activity

  • Everyday activities: 2–3 months.
  • Return to sport: usually from 6 months following full clinical assessment.
  • Final clearance depends on biomechanical and functional testing.

Recovery depends on injury severity, surgical technique and commitment to physiotherapy. Some patients with complex injuries may not regain their previous level of athletic performance.
