The posterior cruciate ligament (PCL) is one of the major intra articular stabilizers of the knee. The PCL can be found deep in the back of the knee, specifically connecting the femur, the thigh bone to the tibia, and the shinbone, and is critical in keeping the knee joint stable. PCL tear can considerably limit the patient’s ability to function and enjoyable lifestyle, especially for those who are physically active or athletes. This blog features information about the causes, PCL injury symptoms, and treatments of PCL tears concerning the points of view of Dr Siddharth Aggarwal, an orthopedic surgeon.
What Is a PCL Tear?
A PCL tear refers to a situation whereby the posterior cruciate ligament is either strained, torn, partially, or wholly. While ACL injuries are quite common, PCL injuries are somewhat less common but just as disabling. The severity of the tear is categorized into three grades:
- Grade I: Slight injury in which no parts of the joint are dislocated, but there is stretching of PCL.
- Grade II: This sort of injury is described as partial thickness and indicates that the PCL is partly torn and the knee is only mild -Moderately lax..
- Grade III: Complete Ligament (PCL) tear with a fair amount of knee instability.
In worst scenarios, the PCL injury can be combined with other bone, ligament, or cartilage injuries of the knee joint.
Causes of a PCL Tear
PCL tears are often a result of high leverage force or a particular force impact on the knee joint. Common causes include:
- Direct Impact: The most common of these is when the front of the knee is hit while the leg is flexed at the knee joint. This is often seen in:
- Motor Vehicle Accidents
- Sports Injuries: Sports that involve tackling or pushing such as football, rugby, or hockey, and contact sports that involve frequent falls such as ice hockey.
- Hyperextension: If the knee is stretched backward beyond what is considered normal then the PCL could be damaged. This is particularly true in physical actions that are characterized by frequent moments of deceleration or change in direction such as basketball or soccer respectively.
- Overuse and Strain: Daily stress or overworking of the knee during sports or exercising damaging or stressing the ligament to the extent that it cannot support the knee any further is a common cause of injury.
- Falls and Accidents: Falling on the side of the leg bowed and getting to rest on a bent knee is also likely to lead to a PCL tear if the force applied is strong.
Symptoms & Signs of a PCL Tear
If a PCL tear is diagnosed early, no other harm to the knee joint or other structures will happen. Common symptoms include:
- Pain and Swelling: In the first days after the injury, pain in the knee and back (in the calf region). One of the prominent features iis that swelling occurs within a few hours because of either inflammation or bleeding.
- Instability: A sensation of the knee buckling that may occur during walking or stair descent or on squatting..
- Limited Range of Motion: Pain when trying to bend or extend the knee as far as one would want.
- Stiffness: Generalized stiffness around the knee joint, which makes it painful to move.
- Bruising: In some instances, you may get a minor skin break and experience discoloration around the knee or shin.
If these are some of the symptoms you notice after you have been involved in a knee-related injury see an orthopedic specialist like Dr. Siddharth Aggarwal.
Process of a PCL Tear
The physical examination to diagnose a PCL tear entails; imaging findings, patient history, and physical examination. Common diagnostic methods include:
- Physical Examination: However, the doctor will evaluate the features of knee stability, the flexibility of the knee joint, and the sensations of pain. Other tests such as the posterior drawer test help in identifying the extent of injury done to the PCL.
- Imaging Tests
- X-rays: Because there might still be issues with the bone such as fractures.
- MRI (Magnetic Resonance Imaging): Enlarged images of soft tissues such as PCL can be seen to establish the size of the tear.
- Patient History: Knowing how the injury happened allows identification of the source of the problem as well as the management plan.
Treatment for PCL tear
In regard to the treatment of a PCL tear, this largely depends on the extent of the injury as well as the patient’s activity level. There are options around treatment without having surgery and with having surgery.
Non-Surgical Treatments
Grade I and Grade II tears may be managed without surgery. These include:
- Rest and Ice: In this case, it is recommended that the patient should avoid activities that stretch the knee. Use of Ice to control inflammation and pain.
- Physical Therapy: Those exercises could help strengthen the knee through the quadricep and hamstring muscles. Active-assisted exercises to regain as much and as soon as possible the normal use of joints.
- Bracing: A knee brace may be prescribed for use to make sure the joint is stabilized well for the duration of the healing period.
- Medications: Painkillers, which include non-steroid anti-inflammatories drugs (NSAIDs).
Surgical Treatments
In some cases where the degree of tear is Grade III or where the conservative treatment has not shown any positive outcome, surgery may be required. Surgical options include:
- PCL Augmentation and Reconstruction: The damaged ligament has to be repaired by using a graft and the common source is the patient’s hamstring, Ankle or patellar tendon. Less invasive approaches always assure quicker rehabilitation.
- Arthroscopy: An operation is conducted through small incisions, with the help of a camera to address the problem with the ligament. Exercise needs to be done after surgery to build muscle strength, balance, and the normal function of the joint.
