Is your knee painful, swollen, or unstable after a fall, collision, or direct impact to the front of the knee?
You might be dealing with a PCL injury – a posterior cruciate ligament (PCL) injury is one that affects the stability of the knee, especially after high-impact trauma, sports injuries, or road traffic accidents. The PCL is one of the key ligaments inside the knee and helps prevent the shin bone (tibia) from moving too far backward in relation to the thigh bone (femur).
Although PCL injuries are less common than ACL injuries, they can still cause pain, swelling, stiffness, and difficulty returning to normal movement or sport. Some PCL injuries can heal with non-surgical care, while more severe or complex injuries may require surgical reconstruction.
At Mubadala Health Dubai, our worldclass team of orthopedic and sports medicine specialists provide comprehensive evaluation and personalized treatment for PCL injuries, helping patients restore knee stability, improve movement, and return safely to daily activities and sport.
Symptoms of a PCL Injury
The symptoms of a PCL injury vary depending on the severity of the tear and whether other knee structures are also involved.
Common symptoms include:
• Pain at the back of the knee
• Swelling that develops within hours after injury
• Knee stiffness or reduced range of motion
• Difficulty bearing weight
• A feeling that the knee is unstable
• Discomfort when walking downhill or going down stairs
• Tenderness around the back of the knee
• Difficulty returning to sports or physical activity
PCL injuries are commonly associated with contact sports such as football, rugby, and skiing. They can also occur during road traffic accidents, particularly when the front of the knee hits the dashboard during impact.
Diagnosis and Evaluation
Accurate diagnosis is important to confirm the PCL injury, determine its severity, and identify whether other structures in the knee have also been affected.
At Mubadala Health Dubai, evaluation may include:
• Detailed medical history and review of how the injury occurred
• Physical examination to assess knee stability, swelling, and movement
• Specific tests to evaluate PCL function
• MRI scan to confirm the diagnosis and assess the extent of injury
• Evaluation of the ACL, MCL, meniscus, cartilage, and other knee structures
• X-rays if fracture or alignment concerns are suspected
This helps our specialists understand whether the injury is isolated or part of a more complex knee injury, allowing them to recommend the most appropriate treatment plan.
Treatment Options for PCL Injuries
Treatment depends on the severity of the injury, knee stability, activity level, associated injuries, and overall health.
Many isolated PCL injuries can be managed without surgery.
Non-surgical treatment include:
• Rest and activity modification
• Knee bracing to support healing
• Pain and swelling management
• Physiotherapy to restore strength and movement
• Exercises to strengthen the muscles around the knee
• Gradual return to daily activity and sport
The goal of non-surgical treatment is to restore stability, improve function, and reduce the risk of long-term knee problems.
When Is Surgery Recommended?
Surgery may be recommended for more severe PCL injuries, particularly when the knee remains unstable or when other ligaments are also injured.
PCL reconstruction may be considered for:
• Complete PCL tears with instability
• Multiple ligament injuries
• Persistent symptoms despite rehabilitation
• High-demand athletes or active individuals
• Associated injuries involving the ACL, MCL, meniscus, cartilage, or other structures
• Cases where knee function remains limited after conservative treatment
PCL reconstruction is usually performed using arthroscopic techniques. Arthroscopy is a minimally invasive approach that uses small incisions, a tiny camera, and specialized instruments to treat the injury inside the joint. During reconstruction, the damaged ligament is replaced with a tendon graft to help restore knee stability.
Recovery and Rehabilitation
Rehabilitation is an important part of recovery from both non-surgical and surgical PCL treatment.
A structured rehabilitation program may focus on:
• Reducing pain and swelling
• Restoring knee range of motion
• Rebuilding strength
• Improving balance and control
• Supporting safe walking, stair use, and daily movement
• Gradually returning to sport or physical activity
• Reducing the risk of future injury
Recovery timelines vary depending on the severity of the injury, whether surgery is required, and whether other knee structures are involved. Your care team will guide each stage of rehabilitation based on healing, strength, stability, and activity goals.
Why Early Treatment Matters
A significant PCL injury can affect the way the knee moves and absorbs force. If left untreated, it may lead to chronic instability, abnormal joint mechanics, cartilage wear, persistent pain, and an increased risk of early joint degeneration.
Early assessment helps confirm the injury, protect the knee from further damage, and guide the right treatment pathway.
When Should You See a Specialist?
You should consider seeing an orthopedic or sports medicine specialist if you experience:
• Knee pain after a fall, collision, or direct impact
• Pain at the back of the knee
• Swelling or stiffness after injury
• Difficulty walking, bearing weight, or using stairs
• A feeling that the knee is unstable
• Symptoms that do not improve with rest
• Difficulty returning to sport or physical activity
• A knee injury after a road traffic accident or contact sport
Prompt evaluation is especially important if symptoms are severe or if the injury involves more than one ligament.
The posterior cruciate ligament, or PCL, is one of the main ligaments inside the knee. It helps prevent the shin bone from moving too far backward and supports overall knee stability.
A PCL injury can range from mild to severe. Some isolated injuries improve with bracing and physiotherapy, while more severe tears or combined ligament injuries may require surgery.
Yes. Many isolated PCL injuries can be treated without surgery through bracing, physiotherapy, and rehabilitation. Your specialist will assess the severity of the tear and overall knee stability before recommending treatment.
PCL reconstruction may be recommended for complete tears, ongoing instability, multiple ligament injuries, or patients who need to return to high-demand sport or activity.
Recovery depends on the severity of the injury and whether surgery is needed. Many patients require several months of rehabilitation, particularly after surgical reconstruction or combined knee ligament injuries.
