Knee Sprain – McKinney, TX
Knee sprain refers to a medical condition when one or more of the ligaments that support the joint are stretched or torn. The knee joint is one of the largest in the body that bears maximum weight and is subjected to a lot of movement. It is supported by four ligaments that connect the bones and help us in walking, running, turning and twisting the leg.

Knee sprains can be categorized into different grades depending on the intensity of the injury and level of damage caused.
These are as follows:

  • Grade 1- this is a minor injury when only a few fibres of the ligament are stretched or torn
  • Grade 2- the ligament is stretched beyond its capacity but the knee function remains intact
  • Grade 3- complete damage of the ligament occurs and it tears apart into two pieces

Causes

  • Physical combat during sport activities
  • Twisting or forceful turning of the foot while it is in contact with the ground
  • If the upper body is twisted while the foot is fixed on the ground
  • Unusual or forceful sideways twisting of the knee
  • Direct hit to the joint
  • Vehicular accidents
  • Overpronation of the foot or flatfeet make a person susceptible to sprains
  • Inherent weakness of the hip abductor muscles
  • Overuse or repeated micro injuries to the joint may damage the ligaments over the time
  • Exercising
  • A fall from a height
  • Past knee injuries increase chances of a sprain

Symptoms

  • The patient may feel considerable pain immediately after the injury
  • Swelling
  • Bruising or discoloration of the skin around the joint
  • The patient may feel the ligament snapping or hear a pop at the time of injury
  • Tenderness
  • Inability to bear body weight
  • The joint feels unstable
  • Visibly twisted or deformed knee
  • Stiffness

Diagnosis

  • Details of the time and mode of injury, medical history and symptoms of the patient are taken into consideration
  • The injured knee is checked through observation and palpation to assess the location of damage and loss of range of motion
  • X-ray imaging may be required to check for bone damage
  • MRI and CT scan reveal soft tissue damage and help assess the grade of injury

Treatment

  • Grade 1 and 2 injuries may be treated by conservative methods while grade 3 injuries require surgical intervention. These may include one or more of the following methods.
  • Rest the injured leg and weight bearing should be avoided
  • Soft bandage may be used for compression and support
  • Ice packs may be applied to curb swelling in the first 24-72 hours of injury
  • The knee should be kept elevated at chest level while resting
  • Pain killers and some anti inflammatory medicines may be prescribed
  • Some gentle exercises and muscle strengthening techniques may be practised under a physical therapy session for improved mobility and flexibility.
  • Use of a splint or a knee brace may be recommended

Arthroscopic surgery may be required in case of severe damage. It is carried out using minimally invasive procedures and the damaged ligaments are either removed, replaced or tightened
