Posterior Cruciate Ligamen Injuries

 Posterior Cruciate Ligament Injuries 

The back cruciate ligament is spotted in the back of the knee. It is one of some ligaments that unite the femur (thighbone) to the tibia (shinbone). The back cruciate ligament keeps the tibia from moving rearward too far.

A damage to the back cruciate ligament necessities a forcing drive. A standard clarification for harm is a bowed knee hitting a dashboard in a car accident or a football player falling on a knee that is turned.


A few skeletal substances meet to structure your knee joint: your thighbone (femur) and shinbone (tibia). Your kneecap sits in front of the joint to give some security.

Bones are copartnered to better bones by ligaments. There are four key ligaments in your knee. They act incline toward robust ropes to keep the skeletal substances as a solitary unit and keep your knee stable.

Collateral ligaments. The proposed are found on the sides of your knee. The average pledge ligament is on the inside and the horizontal insurance ligament is on the outside. They control the sideways movement of your knee and support it in opposition to irregular development.

Cruciate ligaments. The proposed are found within your knee joint. They cross one another to shape a "X" with the front cruciate ligament in front and the back cruciate ligament in back. The cruciate ligaments control the over and over again movement of your knee.

The back cruciate ligament keeps the shinbone from moving counter directionally too far. It is stronger than the first cruciate ligament and is hurt less habitually. The back cruciate ligament has a few parts that intermingle into one structure that is concerning the measure of a single's modest finger.


Damages to the back cruciate ligament are not as normal as different knee ligament wounds. Truth be told, they are frequently subtle and additional troublesome to assess beyond different ligament wounds in the knee.

Numerous times a back cruciate ligament damage happens as well as damages to different structures in the knee for example cartilage, different ligaments, and bone.

Injured ligaments are considered "sprains" and are graded on a severity scale.

Grade 1 Sprains. The ligament is mildly damaged in a Grade 1 Sprain. It has been slightly stretched, but is still able to help keep the knee joint stable.

Grade 2 Sprains. A Grade 2 Sprain stretches the ligament to the point where it becomes loose. This is often referred to as a partial tear of the ligament.

Grade 3 Sprains. This type of sprain is most commonly referred to as a complete tear of the ligament. The ligament has been split into two pieces, and the knee joint is unstable.

Posterior cruciate ligament tears tend to be partial tears with the potential to heal on their own. People who have injured just their posterior cruciate ligaments are usually able to return to sports without knee stability problems.


An injury to the posterior cruciate ligament can happen many ways. It typically requires a powerful force.

  • A direct blow to the front of the knee (such as a bent knee hitting a dashboard in a car crash, or a fall onto a bent knee in sports)
  • Pulling or stretching the ligament (such as in a twisting or hyperextension injury)
  • Simple misstep

The typical symptoms of a posterior cruciate ligament injury are:

  • Pain with swelling that occurs steadily and quickly after the injury
  • Swelling that makes the knee stiff and may cause a limp
  • Difficulty walking
  • The knee feels unstable, like it may "give out"
 Doctor Examination

In the midst of your first visit, your expert will banter with you concerning your symptoms and medicinal history.

Around the same time as the physical examination, your master will check every single trace of the structures of your hurt knee, and difference them with your non-hurt knee. Your hurt knee may appear to hang rearward when bended. It might slide backward too far, in particular when it is bended past a 90° edge. Contrasting tests which may suit your pro avow your investigation fuse X-shafts and alluring thunder imaging (MRI). It is achievable, regardless, for the aforementioned pictures to appear standard, particularly if the harm happened above and past 3 months when the tests.

X-rays. Although they will not show any injury to your posterior cruciate ligament, X-rays can show whether the ligament tore off a piece of bone when it was injured. This is called an avulsion fracture.

MRI. This study creates better images of soft tissues like the posterior cruciate ligament.


Nonsurgical Treatment

If you have injured just your posterior cruciate ligament, your injury may heal quite well without surgery Your doctor may recommend simple, nonsurgical options.

RICE. When you are first injured, the RICE method - rest, ice, gentle compression and elevation — can help speed your recovery.

Immobilization. Your doctor may recommend a brace to prevent your knee from moving. To further protect your knee, you may be given crutches to keep you from putting weight on your leg.

Physical therapy. As the swelling goes down, a careful rehabilitation program is started. Specific exercises will restore function to your knee and strengthen the leg muscles that support it. Strengthening the muscles in the front of your thigh (quadriceps) has been shown to be a key factor in a successful recovery.

Surgical Treatment

Your doctor may recommend surgery if you have combined injuries. For example, if you have dislocated your knee and torn multiple ligaments including the posterior cruciate ligament, surgery is almost always necessary.

Rebuilding the ligament. Because sewing the ligament ends back together does not usually heal, a torn posterior cruciate ligament must be rebuilt. Your doctor will replace your torn ligament with a tissue graft. This graft is taken from another part of your body, or from another human donor (cadaver). It can take several months for the graft to heal into your bone.

Procedure. Surgery to rebuild a posterior cruciate ligament is done with an arthroscope using small incisions. Arthroscopic surgery is less invasive. The benefits of less invasive techniques include less pain from surgery, less time spent in the hospital, and quicker recovery times.

Surgical procedures to repair posterior cruciate ligaments continue to improve. More advanced techniques help patients resume a wider range of activities after rehabilitation.


If your medicine includes surgery or not, recovery plays an essential part in getting you once more to your day by day exercises.

An exercise based recuperation project will help you recapture knee unyieldingness and movement.

Depending on if you had surgery, exercise based recuperation will start 1 to 4 weeks following your method.

To what extent it takes you to recuperate from a back cruciate ligament damage will rely on the severity of your damage.

Joined together wounds regularly have a moderate recuperation, but most patients do well as time goes on.
