to the knee. Other ligaments ACL, or meniscus, may be torn along with a MCL injury. Symptoms The most common symptom following an MCL injury is pain directly over the ligament. Swelling over the torn ligament may appear, and bruising and generalized joint swelling are common 1 to 2 days after the injury. In more severe injuries, patients may complain that the knee feels unstable. Treatment Treatment of an MCL tear depends on the severity of the injury. Treatment always begins with allowing the pain to subside, beginning work on mobility, followed by strengthening the knee to return to sports and activities. Bracing can often be useful for treatment of MCL injuries. Fortunately, most often surgery is not necessary for the treatment of an MCL tear. Treatments For Unhappy Triad Injury Treatment of the unhappy triad usually requires surgery. An ACL surgery is common and the meniscus can be treated during the surgery as well. The MCL is rehabilitated through time and immobilization. Physical therapy after the surgery and the use of a knee brace help speed up the healing process. A typical surgery for a blown knee includes: Patellar tendon autograft (An autograft is a graft that comes from the patient) Hamstring tendon autograft Quadriceps tendon autograft Allograft (taken from a cadaver) patellar tendon, Achilles tendon, semitendinosus, gracilis, or posterior tibialis tendon The goal of reconstruction surgery is to prevent instability and restore the function of the torn ligament, creating a stable knee. There are certain factors that the patient must consider when deciding for or against surgery. An important post-surgical treatment of unhappy triad is Physical Therapy (PT). PT includes exercise ambulatory programs, mobilizations, and modalities to help ease symptoms and speed up the recovery process. The purpose of physical therapy is strengthening muscle and increasing the knee's range of motion without damaging the new grafts. Exercise ambulatory programs are prescribed by a Physical Therapist and should be used during recovery. Physical Therapist will provide immediate knee mobilization manually or with continuous passive motion (CPM) within the first week. Neuromuscular electrical stimulation (NMES) should be used for a span of 6-8 weeks postoperative. Immediate cryotherapy could be used for treatment as well. A combination of functional tests and validated patient-reports are used to determine a patient’s readiness to return to activities.
