The negative effects of anterior cruciate ligament injury during stroke rehabilitation

Musculoskeletal problems are commonly reported after stroke resulting in abnormal gait biomechanics, pain, and limitation in performing activities of daily living. Anterior circulate ligament is the most frequently injured knee ligament accounting for approximately 50% of all ligament injuries; however, post stroke anterior cruciate ligament injury is rarely reported. We present a case of a 58-year-old female admitted for inpatient stoke rehabilitation after a left middle cerebral artery stroke. After gaining considerable functional recovery, she was planned to be discharged in two weeks’ time when she tripped resulting in a torn anterior cruciate ligament on the hemiperetic side. This resulted in increase in the length of stay and loss of functional gains. We discuss the possible mechanisms and the management plan. Patients with stroke should be monitored for musculoskeletal complications and preventive strategies should be devised to protect from possible ligamentous injuries of the knees.
