Knee Pain Related to Injuries

A knee injury can affect any of the tendons, ligaments surrounding the knee joints, cartilages, ligaments and bones that form the joint itself. Some of the reason for pain in knee can be due to the more common knee injuries which are listed below as these can flare up and hurt you all the time if they are not treated properly.

ACL Injury 

An ACL injury is nothing but a tear of the anterior cruciate ligament (ACL) which is amongst the 4 ligaments and one of the strong bands of tissue that connect the shinbone (tibia) to your thighbone (femur). This reason for pain in knee is particularly common in people who are active in sports like volleyball, basketball, soccer or other sports which require sudden changes in direction.


Another reason for pain in knee is where the bones including the kneecap (patella) can be broken during accidents or falls. Also, people whose bones are weakened and brittle by osteoporosis can sometimes sustain a sudden or unexpected knee fracture even with mild stresses like bending over or coughing etc.

Knee Bursitis

The reason for pain in knee can be because of the injuries which causes inflammation in the bursae (small sacs of fluid under the skin and above the joint to cushion the outer side of the knee joint) which helps the tendons and ligaments to glide smoothly over the joint. Overuse, repeated bending and kneeling or falls can irritate the bursa on top of your kneecap leading to pain or swelling.

Patellar Tendinitis

Tendinitis causes inflammation and irritation of more or more tendons (the thick fibrous tissues that aids in attaching the muscles to bones). The inflammation is the reason for pain in knee that can occur when there is an injury to the patellar tendon which runs to the shinbone from the patella (kneecap) and allows you to run, jump and kick. Runners, cyclists, skiers, and those who are involved in jumping sports and activities highly develop patellar tendinitis.

Torn Meniscus

The meniscus is the tough, and rubbery cartilage which acts as a shock absorber between your thigh bone and shinbone. It can be torn if there is a sudden twist in your knee making it the reason for pain in knee especially while bearing weight on it.

  • Septic Arthritis – when the reason for pain in knee is due to infection which leads to swelling, pain and redness, septic arthritis occurs often with a fever causing no trauma before the onset of pain but it can require immediate medical attention when there is a quick extensive damage to the knee cartilage.
  • Gout – when uric acid crystals build up in the joint, it gives rise to this type of arthritis by commonly affecting the big toe, and can also occur in the knee.
  • Pseudogout – It is another reason for pain in knee where calcium-containing crystals start developing in the joint fluid affecting mostly the knee.

Mechanical Problems of Knee

Some of the mechanical problems which are considered to be the reason for pain in knee can be because of:

  • Hip or Foot Pain

  • Iliotibial Band Syndrome

This reason for pain in knee occurs when the tough band of tissue that extends from the outside of the hip area to the outside of the knee (iliotibial band) becomes so tight when it rubs against the outer portion of the thigh bone. Cyclists and distance runners are more prone to iliotibial band syndrome.

  • Patellofemoral Pain Syndrome 

Tightness, muscle imbalance and alignment problems of the legs usually cause this condition. It can be the reason for pain in knee as it causes occasional ‘buckling’ (knee is unable to bear your weight). It is not because of an injury and is more common for women compared to men.
