What Everybody Ought to Know About Collateral Ligament Sprains

The collateral ligaments are found either side of your knees and assist with controlling the sideways motion of your knee and brace it against unusual movement.  You can sustain a sprain to these ligaments via any direct contact to the knee or hard muscle contraction.  According to OrthoInfo, these can be graded to tell the level of injury as follows:

Grade 1 Sprains. The ligament is mildly damaged in a Grade 1 Sprain. It has been slightly stretched, but is still able to help keep the knee joint stable.

Grade 2 Sprains. A Grade 2 Sprain stretches the ligament to the point where it becomes loose. This is often referred to as a partial tear of the ligament.

Grade 3 Sprains. This type of sprain is most commonly referred to as a complete tear of the ligament. The ligament has been split into two pieces, and the knee joint is unstable.

The most commonly injured collateral ligament is on the medial side (the side closest to the other knee).  You may experience swelling and pain around the site injury, and a feeling of giving way in the knee.  These injuries can be treated conservatively with icing, bracing and physiotherapy to restore range of movement and muscle strength.

If the injury is more severe or has not healed conservatively it will require surgical repair, which your specialist knee consultant will discuss with you.  You will also require physiotherapy after surgery to regain full range of movement and muscle strength for knee stability.  After treatment, you will gradually return to sports activities.
