A strain or sprain of the tibiofibular ligament is caused by a force or stress that is greater than the ligament can withstand. This can occur during strenuous activity such as running, jumping, or landing from a height, or as a result of a sudden twist or turn of the knee or ankle.
Diagnosis of a strain or sprain of the tibiofibular ligament is based on a physical examination and medical history. The doctor may also order imaging tests such as X-ray or MRI to confirm the diagnosis.
Other possible diagnoses that need to be considered include tendonitis, bursitis, fractures and dislocation.
Treatment for a strain or sprain of the tibiofibular ligament typically involves rest, ice, elevation and immobility of the affected area. Non-steroidal anti-inflammatory drugs may also be prescribed to reduce pain and inflammation. Physical therapy may also be recommended to help restore strength and function.
Most strains and sprains of the tibiofibular ligament can heal with rest, ice and elevation. However, if the injury is severe, surgery may be necessary to repair or replace the ligament. The prognosis for a full recovery is generally good with appropriate treatment.
