The Posterior Cruciate Ligament (PCL) is an important ligament located in the center of the knee that connects the femur and tibia. The PCL plays a role in keeping the knee stable and preventing excessive backward movement. When the PCL ruptures, the stability of the knee is lost, which greatly interferes with daily life and sports activities. This article provides a detailed explanation of the symptoms and treatment of posterior cruciate ligament rupture.

Symptoms of posterior cruciate ligament rupture
acute symptoms
- Knee pain : The most common symptom of a PCL tear is deep knee pain, which can be severe, especially immediately after the injury.
- Swelling : After an injury, your knee may swell, which usually peaks within 24 hours.
- Instability : You may feel that your knee is unstable, especially when going down stairs or performing other activities that put stress on your knee.
chronic symptoms
- Persistent pain : Over time, pain may persist, especially after exercise or prolonged walking.
- Limited range of motion : Your knee may have limited range of motion. You may have difficulty fully extending or bending your knee.
- Muscle weakness : The muscles around the knee can become weak, which can lead to further instability in the knee.
Causes of posterior cruciate ligament rupture
The main cause of PCL tears is a strong external force applied to the knee. Specifically, the following situations are possible:
- Car accidents : Hitting your knee hard against the dashboard can tear your PCL.
- Sports injuries : In sports such as soccer, rugby, and skiing, knee injuries can occur due to direct impact.
- Falls : Falling on a bent knee can also tear the PCL.
Diagnosis of posterior cruciate ligament rupture
- History and physical examination : First, the doctor will ask you detailed questions about your symptoms and injuries. Next, they will inspect your knee for swelling or deformity.
- Manual Examination : Manual examinations such as the posterior drawer test and Lachman test are performed to assess knee stability.
- Imaging : X-rays and MRIs can be used to confirm a PCL tear. MRIs are especially useful for showing detailed damage to the ligament.
Treatment for posterior cruciate ligament rupture
Conservative therapy
- Rest and ice : Initial treatment involves resting and icing the knee. Icing for 20 minutes several times a day is recommended to reduce swelling and pain.
- Compression and elevation : Compressing the knee with a compression band or bandage can help reduce swelling, and elevating the knee above heart level can also help reduce swelling.
- Physical therapy : Rehabilitation will be performed to strengthen muscles and improve range of motion. Exercises will be performed under the supervision of a physical therapist to restore stability to the knee.
surgical therapy
Surgery may be considered if conservative treatment does not improve symptoms or if the patient wishes to return to competition.
- PCL reconstruction : The PCL is reconstructed using an autologous tendon (the patient's own tendon) or an artificial ligament. The surgery is usually performed using an arthroscopic procedure.
- Post-operative rehabilitation : After surgery, rehabilitation is done in stages. The knee is immobilized for a few weeks, and then exercises are gradually implemented to increase range of motion and restore muscle strength.
prevention and control
- Proper training : Strengthening the muscles around the knee and keeping them flexible can reduce the risk of PCL tears.
- Use proper equipment : Using knee supports or braces during sports activities can help keep your knee stable and reduce the risk of injury.
- Early treatment : If you experience knee pain or instability, it is important to see a doctor as soon as possible. Early treatment can prevent the condition from worsening.
summary
A posterior cruciate ligament tear is an injury that has a significant impact on the stability of the knee. Early diagnosis and appropriate treatment can speed recovery and help return to daily life and sports activities. If you experience pain or instability, we recommend that you seek medical attention immediately. A combination of physical therapy and surgical therapy can help many patients regain an active life.
