These injuries are therefore more common in contact sports like football, but can also result from non-athletic injuries like a bumper or dashboard injury to the shinbone during a car accident. PCL tears can occur in isolation or, more commonly, together with injury to other stabilizing structures of the knee. The athlete will usually complain of knee swelling and pain after a forceful blow or landing. If other ligaments are injured, the knee may also be more unstable with side-to-side or rotational movement as well.
Share on Facebook Ligaments are fibrous soft tissue that connect your bones, stabilize your joints and keep your body aligned. They're often mistaken for tendons, which attach muscle, not bone, to bones.
Ligaments have limited elasticity that allows stretching slightly beyond the usual range of motion, but not much more than a few millimeters to centimeters beyond that. The exact amount of flexibility varies joint by joint and person by person, but ligaments as a rule are not as elastic as muscle tissue.
What Are Ligaments Made Of? Ligaments are made of long strings of collagen that have two main components: Fibroblasts are a type of protein needed for your body to make connective tissue like collagen.
The cells that make up your ligaments are held together by another type of protein, called proteoglycans. When your body produces collagen, the proteoglycan cells synthesize it and make it usable.
How Ligaments Work The long strings of collagen that make up the ligaments are very tough and course, like very thin rope.
They loop around and through the bones in your joints -- and cross over each other to reinforce their strength and keep your joints in place. They also give your joints a bit of cushioning, so you don't have to experience the physical pain of bone hitting bone.
Injury Ligaments have finite elasticity for a reason: If they didn't, your joints wouldn't work. But repeated physical strain can damage them -- that's why some athletes get ligament injuries in knees and other joints.
One example is the ACL injury, a tear in the body's anterior cruciate ligament in the knee. This injury can cause severe pain and even make it difficult to walk. Ligaments in your feet can be injured if you stretch your toes too far inward toward your body. Any ligaments can be torn in this way, but knee and foot injuries are more likely because joints in the feet and knees bear so much of your body's weight.
Healthy Ligaments Unfortunately, there's no one foolproof way of preventing injury to your ligaments. Avoiding obesity helps as excess weight takes a long-term toll on your ligaments and leads to injury over time.
Incorporate strength-conditioning exercises like weight training into your workout to keep your ligaments strong. Just don't push the weights too hard. It's easy to strain your ligaments if you use too heavy a weight too soon.ACL Tear The anterior cruciate ligament is the most commonly injured ligament in the knee.
