When To Call A Professional

Call your doctor immediately if your knee becomes swollen or deformed, even if it is not painful. This is especially important if you cannot bear weight on your injured knee or if the knee feels as if it will buckle or "give out."

Prognosis

About 90% of patients with ACL injuries fully recover, as long as they faithfully follow a good rehabilitation program. As a long-term complication, some patients with Grade III ACL injuries may eventually develop symptoms of osteoarthritis in the injured knee joint. According to one study, 50% to 60% of patients who suffered a severe ACL sprain showed X-ray evidence of knee osteoarthritis within 5 years after their ACL injury.
