Good evening How long does it normally take to recover from a sprained MCL in the Knee? thank you

Symptoms of a medial collateral ligament injury tend to correlate with the extent of the injury. MCL injuries are graded on a scale of I to III.
• Grade I MCL Tear
This is an incomplete tear of the MCL. The tendon is still in continuity, and the symptoms are usually minimal. Patients usually complain of pain with pressure on the MCL. It's recovery time is 1-2 weeks. Treatment: resting from activity, Icing the injury and anti-inflammatory medications
• Grade II MCL Tear
Grade II injuries are also considered incomplete tears of the MCL. The pain and swelling is more significant, and usually a period of 3-4 weeks of rest is necessary. The use of a hinged knee brace is common in early treatment.
• Grade III MCL Tear
A grade III injury is a complete tear of the MCL. Patients have significant pain and swelling, and often have difficulty bending the knee. Instability, or giving out. A knee brace or a knee immobilizer is usually needed for comfort, and healing may take 6 weeks or longer. Complete rehab can take 3-4 months.
