Common Injuries - Knee

Anterior Cruciate Ligament (ACL) Tear

A tear in the Anterior Cruciate Ligament is a common knee injury resulting from the change in turning and suddenly going different directions.  Some ways in which the ACL is torn also include over extending the knee, and landing a jump with the knee bent and twisting. 

Chondromalacia Patella

Commonly referred to as Runner’s Knee, Chondromalacia Patella is damage to the cartilage underneath your kneecap. This is caused by excessive overuse of the knee, misalignment of the kneecap, or arthritis. Some people experience swelling to their kneecap and others have even reported a grinding sensation while running or walking. 

Patella Tendonitis

Also known and Jumper’s Knee, this injury involves the tendon connecting the patella to the shinbone, and Patella tendonitis is most common in athletes that are frequently jumping in sports causing the patella to inflame.  

Knee Arthritis

Knee arthritis is a form of osteoarthritis that is caused by progressive knee joint degeneration usually from overuse or a pervious injury to the knee. A few symptoms of knee arthritis are knee swelling and pain which is usually found in middle aged people.

Lateral Collateral Ligament (LCL) Injury

The Lateral Collateral Ligament is located on the outside of the knee, and connects the shin bone to the thigh bone. This injury is usually caused by the knee twisting suddenly during sports.

Medial Collateral Ligament (MCL) Tear

The Medial Collateral Ligament is located on the inside of the knee, and connects the shin bone to the thigh bone.  This injury is usually caused by the knee twisting suddenly during sports.

Osgood Schlatters

Most common in adolescents aging anywhere from 9-14 who are involved in physical sports or who have experienced a “growth spurt.” Osgood Schlatters is the overuse of the knee which results in a small lump appearing right below your knee cap causing pain.

Osteochondritis Dissecans

This disorder is usually apparent in teenagers and rarely occurs later in life. Osteochondritis Dissecans is a disorder in which pieces of bone break off of the knee joint making it difficult for regular knee use. When this disorder is present there is much swelling and knee pain.

Patella Fracture

An injury involving the kneecap is a patella fracture.  Usually this injury includes a direct blow or fall on the kneecap. A patella fracture can also occur from the quadriceps muscles contraction while the knee joint straightens.

Posterior Cruciate Ligaments (PCL) Tear

In most Posterior Cruciate Ligament tears no visible swelling or pain is evident, and it is usually caused by direct force to the upper shin.  The Posterior Cruciate Ligament is stronger and larger then the Anterior Cruciate Ligament, and as long as no other knee structures are injured the healing time is shortened a great deal.

Tibia/Fibula Fracture

Many times the fibula breaks along with a tibia break because the bones are connected, and the tibia is the only weight bearing of the two.  The tibia is considered the shin bone, and the fibular is the considered the splint bone along the outside of the leg.

Torn Cartilage Knee Injury

The specific cartilage in the knee is referred to as the meniscus, and provides a cushion between the knee bones.  Once part of the meniscus is torn the knee will swell up and be very painful.  Tearing cartilage is a very common injury for athletes.
