Patient-reported outcome and muscle strength after a physiotherapy-led progressive exercise programme and a support brace in patients with an acute injury of the posterior cruciate ligament: a 2-year follow-up study

Posterior Cruciate Ligament (PCL) injuries can be treated surgically or with progressive exercises in combination with a support brace. Nevertheless, larger prospective studies reporting outcome of exercise-related treatment are lacking. We aimed to investigate changes in patient-reported outcome of a physiotherapy-led progressive exercise programme and a support brace in patients with an acute injury of the PCL over 2-year follow-up. Furthermore, to investigate changes in isometric knee muscle strength over 8-month follow-up, and finally to report conversion to surgical reconstruction over 2-year follow-up .
