Although medial collateral ligament (MCL) injuries were treated surgically in the past, recent studies have clearly shown that these injuries are best treated nonoperatively. Use of a knee immobilizer is discouraged for extended periods of time because loss of range of motion is likely. Thus, the use of a hinged knee brace is favored. Some physicians recommend that motion be restricted to approximately 30 to 60 degrees for the first portion of brace treatment, but there is no universal consensus on how long or how much restriction should be recommended.
