NC93.5/S83.4 Strain or sprain involving fibular or tibial collateral ligament of knee



A strain or sprain to the fibular or tibial collateral ligament of the knee is usually caused by a sudden twist or quick change in direction, or a direct blow to the knee.


Diagnosis is usually made through physical examination and imaging tests such as an X-ray, MRI or CT scan.

Differential diagnosis

It is important to differentiate this condition from other knee injuries such as a meniscus tear, ligament tear, or tendonitis.


Treatment depends on the severity of the injury, but typically includes rest, ice, compression, elevation, and physical therapy. In some cases, surgery may be necessary to repair the ligament.


With treatment, the prognosis for a strain or sprain of the fibular or tibial collateral ligament of the knee is usually good. However, it can take several weeks or months for the injury to heal completely.
