Knee Injury

Knee – the largest joint in the human body, is the most common site for injury among young athletes. The knee joint comprises three bones namely the Femur (upper leg bone), the Tibia (lower leg bone) and the Patella (kneecap). An injury to any of these bones causes immense pain in the knee joint. A knee injury can also occur when the muscles, tendons and four critical ligaments i.e. the Anterior Cruciate Ligament (ACL), the Posterior Cruciate Ligament (PCL), the Medial Collateral Ligament (MCL), and the Lateral Collateral Ligament (LCL), get damaged.

Common Knee injuries


A fracture in the Patella, Femur or Tibia bone is termed as a knee fracture. The main causes of this injury are direct blow (from falling off a bicycle, motor vehicle collision, athletic accidents etc), jumping activities (such as basketball, gymnastics, football etc) or falling from a significant height. A person who has suffered a knee fracture typically experiences pain, swelling, bruising and tenderness in the knee area. The treatment of the knee injury depends upon the type of fracture and which particular bone is broken.  Accordingly, splints, casts, medication or surgery may be recommended.


A Knee Dislocation occurs when the bones of the knee slide out of place. The main causes for this type of knee injury are high energy trauma from motor vehicle crashes, sports injuries and falls. A person with Knee Dislocation experiences extreme pain, tenderness and swelling in the knee. The knee gets bent and cannot be straightened. The treatment of the knee injury starts with ice application (to control swelling). The affected knee is then immobilized using a splint. The knee doctor will then assess the extent of dislocation and accordingly proceed with the realignment of the bones.

Anterior Cruciate Ligament (ACL) Injuries

An ACL Injury occurs when the knee is bent, twisted or straightened beyond its limit. The knee injury is most common in athletes participating in soccer, football, and basketball. The main causes are changing direction rapidly, landing from a jump incorrectly and falling off from a height. ACL Injury leads to significant swelling and deformity in the knee joint. The affected area may also get discolored due to bleeding from inside of the knee joint.  The doctor performs RICE treatment to alleviate pain and reduce swelling. He may also suggest you to wear a knee brace to stabilize the knee joint and prevent it from injury.

Posterior Cruciate Ligament Injuries

A partial or complete tearing of the Posterior Cruciate Ligament (PCL) in the knee leads to PCL Injury. The knee injury occurs less frequently than ACL Injury and also causes lesser pain and instability. However, the injury is enough to sideline you for several weeks. The Posterior Cruciate Ligament gets injured mainly from overextension of the knee or a blow to the front of the knee while the knee is bent (for instance, motor vehicle crashes or falling hard on knee).   Knee pain, swelling and instability are the common symptoms. The doctor may recommend ICE application, splints and NSAIDs for the treatment of the knee injury.

Collateral Ligament Injuries

A Collateral Ligament Injury occurs when the ligament on the outer side of the knee tears or gets stretched. The knee injury occurs less frequently than other types of knee injuries. Major causes are over stretching of the knee or direct blow to the outside of the knee. A person suffering from Collateral Ligament Injury experiences swelling in the knee joint, accompanied with pain and tenderness in the outer portion of the knee. The treatment involves RICE application, immobilization, physical therapy and NSAIDs.

Meniscal Tears

The knee injury is caused by a forceful twisting or hyper-flexing of the knee joint. It most commonly occurs during sports activities that involve twisting, cutting, pivoting, or tackling. The symptoms include pain, swelling, popping, and feeling of giving way. The knee doctor may perform surgery to repair the damage. However, if the knee injury is not severe, it can be treated with physical therapy and muscle strengthening exercises.

Tendon Tears

It occurs when the quadriceps and patellar tendons in the knee joint get stretched or torn. It is most common in athletes who participate in running or jumping sports. The factors that lead to the knee injury include falls, awkward landing from jumps and direct force to the front of the knee.
