In most cases, a torn MCL will not require surgery. MCL injuries are graded 1, 2 and 3.
Grade 1 tears are considered mild sprains. Treatment consists of icing, physical therapy and anti-inflammatory medications. Most patients can get back to pre-injury level of activity without difficulty.
Grade 2 tears are moderate to partial tears of the MCL. A brace is usually recommended to provide stability to the knee. You may or may not require crutches. The remainder of treatment is the same as a Grade 1 injury. Recovery may take four to six weeks.
Grade 3 tears are considered complete tears of the MCL. A consultation with an orthopaedic physician is usually recommended. If the injury is isolated to an MCL tear, patients may need to use crutches for a week or two. A brace would be used to provide stability to the knee during the healing process. The remainder of the treatment plan would be the same as Grade 1 or 2. Generally speaking, the recovery time may take two to four months of treatment.
