Knee Sprain: Causes, Symptoms And Treatment

by Administrator 27. June 2016 13:10

The knee joint consists of four major ligaments - Anterior Cruciate Ligament (ACL), Posterior Cruciate Ligament (PCL), Medial Collateral Ligament (MCL) and Lateral Collateral Ligament (LCL). Injury to any of these ligaments is termed as a knee sprain. It may either involve minor stretching of the ligament or it may get completely torn and detached from the bone. This may eventually result in severe instability of the joint.

Causes

  • Sudden twisting of the knee
  • Stretching the knee beyond its range of motion
  • Falling on the knee
  • Sports injury
  • Bending the knee backwards
  • Car accident
  • Extreme force that pushes the knee inwards

Symptoms

  • Pain and inflammation
  • Bruising and stiffness
  • Inability to walk properly
  • A popping sound emanates from the knee at the time of injury
  • The knee may give out when trying to stand
  • Discoloration around the knee
  • Inability to participate in sports activities

Diagnosis

  • The doctor may note down the medical history of the patient along with the symptoms and cause of injury.
  • The doctor may check for inflammation and signs of deformity
  • The strength of the ligaments and range of motion of the knee will also be tested
  • Further diagnostic tests such as X-rays may be conducted to identify a fracture or severe ligament damage
  • Magnetic Resonance Imaging (MRI) or arthroscopy may also be required in some cases

Treatment

  • Resting the injured joint and keeping the leg elevated above heart level
  • Application of ice packs to the injured area may help in reducing inflammation
  • An elastic bandage may be used to compress pain and swelling
  • The doctor may suggest wearing a knee brace to provide support to the joint and allow it to heal completely
  • Non-steroidal anti-inflammatory drugs (NSAIDs) may be prescribed to provide relief from swelling

Surgical treatment

Surgical intervention may be required in case of severe sprains. The doctor may perform knee reconstruction surgery. In this procedure, a tissue graft may be taken from the patellar or hamstring tendons and inserted in place of the torn ligaments.
