Does a PCL Injury Require Surgery?

No, a PCL injury does not always require surgery. Most low-grade posterior cruciate ligament injuries heal with non-surgical treatment like rest, crutches, and a knee brace. However, if you have a completely torn PCL that affects other ligaments like the ACL or MCL, orthopedic surgeons may recommend surgical repair using a PCL graft.

At Total Orthopedics & Sports Medicine, our board-certified knee specialists treat all types of posterior cruciate ligament (PCL) injuries. To start, we use imaging tests like MRIs and CT scans to check the damage inside your knee joint. After that, we create a treatment plan that may include NSAIDs, a knee brace, or surgical PCL reconstruction. Call us at 855-321-6784 to relieve knee pain and start your recovery.

When Should You Consider Surgery for a PCL Injury?

You should consider surgery for a PCL injury if you have grade III PCL tears (complete tear), ongoing knee instability, or sharp knee pain. You may also need surgery if the injury prevents you from returning to normal activities, sports, or physical work. Other than that, you should consider surgery when a PCL injury damages other knee ligaments (the anterior cruciate ligament/medial collateral ligament).

To restore complete knee stability, surgeons may recommend one of the following procedures, depending on your injury type:

• PCL Reconstruction: Surgeons remove the torn posterior cruciate ligament and replace it with a new graft. The graft may come from your tissue or a deceased donor, and it stabilizes the knee joint.
• Multiligament Reconstruction: Surgeons perform this procedure when a PCL injury occurs with other ligaments, like the ACL or LCL. They repair or reconstruct all damaged ligaments in one surgery to restore full knee function.
• Revision PCL Surgery: Doctors recommend this if a previous PCL surgery failed or the graft did not heal properly. Surgeons revise the old reconstruction by replacing it with a new graft.

What Factors Impact the Decision of PCL Reconstruction?

Surgeons consider factors like your age, activity level, and whether you’re an athlete or a laborer. Beyond that, they check the degree of knee instability, ligament laxity, and additional ACL, MCL, or LCL injuries. Here’s how each of these factors helps determine if PCL reconstruction is suitable for you:

Age and Activity Level

Younger, active individuals often require PCL reconstruction, especially if they engage in sports or physical labor. This is because their knee joints face significant stress daily, so a torn PCL can quickly lead to serious instability. However, younger patients tend to heal faster and respond better to surgery. On the other hand, older adults may have slower healing, so doctors may avoid surgery unless symptoms are severe or long-lasting.

According to NCBI, a case-control study reviewed PCL reconstruction in patients aged 50 and older. Then, the researchers compared them with younger patients. Older adults had lower functional scores on tests like IKDC, Lysholm, and Tegner. They also showed more looseness in the knee joint (posterior laxity). Moreover, the success rate was also lower (78.6% vs. 100%)

Other Ligament Injuries

PCL injuries often occur with damage to other key ligaments, such as the ACL, MCL, or LCL. When more than one ligament is torn, the knee loses its stability and strength. In such cases, surgeons usually recommend multiligament reconstruction during a single procedure. Repairing all injured ligaments at once helps restore joint function, improves balance, and reduces the risk of permanent limited mobility.

Knee Instability and Laxity

Surgeons look for signs of looseness in your knee, known as ligament laxity. To begin, they use the posterior drawer test. According to PubMed, this test is the most accurate clinical method for diagnosing PCL laxity. During this test, the surgeon gently pushes the shin bone and thigh bone backward while the knee is bent. If the bone moves too far, it signals PCL damage and may indicate the need for reconstruction.

Overall Health

Your overall health strongly affects whether PCL reconstruction is a safe and effective option. For example, certain medical conditions can make healing slower and raise the risk of complications after surgery, such as:

• Diabetes
• Obesity
• Heart disease
• Smoking
• A weakened immune system

That’s why our surgeons carefully review your medical history, physical condition, and ability to recover before making a final decision. Contact us today to explore your safest treatment options.

Are There Different Grades of PCL Tears?

PCL injuries are classified into three grades: grade I (mild sprain), grade II (partial tear), and grade III (complete tear). Each grade affects knee stability differently and requires a different treatment approach based on injury severity. Here’s what each grade involves and how it impacts your movement and knee joint:

Grade I: Mild Sprain

A Grade II PCL injury involves minor ligament stretching without a tear. According to NIH, this level of injury shows 1–5 mm of backward movement (posterior translation) of the tibia. Because the ligament remains mostly intact, the knee stays stable, and symptoms are usually mild. In these cases, most people recover with:

• Rest and temporary activity modification
• A knee brace to limit backward motion
• Exercise to rebuild strength

Grade II: Partial Tear

A Grade II PCL injury involves a partial tear of the ligament fibers. This damage weakens the PCL’s ability to stabilize the knee, especially during twisting or pivoting movements. As the ligament strain increases, the knee joint feels unstable and gives way under pressure. This often leads to swelling, tenderness, and moderate pain.

Grade III: Complete Tear

A Grade III PCL injury is a complete rupture of the ligament, often accompanied by a popping sound at the time of injury. This leads to significant instability, difficulty walking, and immediate swelling. Moreover, the knee may buckle during movement, making it difficult to walk or bear weight. To restore stability and support long-term knee function, your surgeons may recommend surgical treatments such as:

• Autograft PCL reconstruction
• Allograft PCL reconstruction
• Double-bundle PCL reconstruction

How Do Knee Specialists Diagnose PCL Injuries?

To diagnose a PCL injury, knee specialists begin asking about your symptoms, such as pain, swelling, or instability after the injury. They also review how the knee injury happened, such as from a fall, a sports impact, or a car accident. This information helps them understand the severity and location of the damage.

Next, they conduct a thorough physical exam. This includes checking for joint swelling, skin tenderness, bruising, and how well your knee bends and straightens. If your knee moves unusually or feels weak under pressure, it may suggest damage to the PCL or other ligaments.

To confirm their diagnosis, specialists also use advanced imaging tools like:

• MRI shows the condition of soft tissues like ligaments, cartilage, and menisci.
• X-rays help rule out bone fractures or joint dislocations.
• CT scans give a detailed view of bone alignment and any joint damage.

What Are Non‑Surgical Treatment Options for PCL Injuries?

Non-surgical treatment for PCL injuries usually begins with rest, ice, compression, elevation (RICE), and pain medication. Doctors also recommend bracing to prevent unnecessary movement and protect the healing ligament. Here’s how each method reduces pain, supports the joint, and restores function over time:

• Rest: Limits knee movement and protects the ligament during early healing. This prevents further damage and gives tissues time to recover.
• Ice: Helps reduce swelling and pain after the injury. Moreover, applying it regularly lowers inflammation and speeds up recovery.
• Compression: Compression wraps help reduce fluid buildup in the joint, improve blood flow, and keep swelling from worsening.
• Elevation: Raising the leg above heart level helps drain excess fluid. This eases pressure inside the knee and reduces stiffness.
• Pain Medication: Over-the-counter NSAIDs like ibuprofen or naproxen relieve pain and lower swelling around the ligament.
• Bracing: A PCL-specific brace prevents the tibia from moving too far backward, which protects the healing ligament.

Can PCL Injuries Be Treated with Regenerative Medicine?

Yes, specific PCL injuries, especially mild or partial tears, can be treated with regenerative medicine. For example, treatments like platelet-rich plasma (PRP) or stem cell therapy use your body’s own healing cells to repair the damaged ligament. These methods may ease pain, speed up recovery, and improve strength over time. However, they work best when the knee is still stable and no other major ligaments are torn.

If you’re dealing with a PCL injury and want to avoid surgery, our doctors can assess whether regenerative options like PRP or stem cell therapy are right for you. Reach out today to explore safe, non-invasive treatments that support healing and help you return to daily activities.

Do PCL Injuries Affect an Athlete’s Performance?

Yes, PCL injuries can significantly impact athletic performance, especially in sports that require cutting, jumping, or sudden stops. In high-impact activities football, soccer, basketball), even a mild PCL tear may reduce knee stability and slow reaction time. Without proper treatment and rehabilitation, athletes may struggle with balance, speed, and joint control.

In more severe cases, a complete tear may lead to chronic instability, limiting an athlete’s ability to pivot or bear weight on the affected leg. This affects an athlete’s ability to play at full intensity or maintain proper form under pressure. Over time, the body may develop poor movement patterns, placing extra stress on nearby joints and muscles. That’s why a targeted rehabilitation program is essential for restoring complete joint control and preventing long-term complications.

How Can You Prevent PCL Tears?

You can prevent PCL tears by strengthening leg muscles, improving joint control, and avoiding high-risk movements. In particular, exercises that target the quadriceps and improve hamstring flexibility help protect the ligament during sudden impacts. When performed consistently, targeted exercises gradually build knee support and reduce stress on the PCL, lowering the risk of injury. Here are some effective exercises that help prevent PCL injuries:

• Wall sits: Strengthen the quadriceps without straining the knees
• Hamstring curls: Improve posterior thigh support and control
• Step-ups: Enhance balance and activate stabilizing muscles
• Leg presses: Build overall leg strength while protecting the joints
• Glute bridges: Support knee alignment through hip activation

In addition to strength training, use safe movement patterns in sports and daily routine. For instance, wearing sport-specific shoes and an elastic bandage, using proper equipment, and practicing balance drills reduce strain on the knee. These preventive steps improve knee stability, reduce stress on the PCL, and lower the risk of injury during activities.
