Symptoms of an Unstable Knee
An unstable knee causes pain, swelling, stiffness and a tendency of the joint to buckle or give way.
Diagnosis of an Unstable Knee
When you present with these symptoms, your doctor diagnoses knee instability by performing a thorough physical examination to test the stability of each ligament and may order imaging tests such as X-rays, MRI or CT scans to confirm the diagnosis.
Treatment of an Unstable Knee
Treatment depends on the cause and severity of the condition. Initially, your surgeon may recommend conservative treatments such as rest, ice application, compression and elevation of your leg (R.I.C.E.), physical therapy and use of braces. Pain relieving medications may be prescribed for symptomatic relief.
However, when these conservative treatments yield an unsatisfactory response, surgical correction may be recommended. Considering the type and severity of an injury, your surgeon decides on the surgical repair or reconstruction of the joint by replacing the damaged parts with a prosthesis.
