Functional training for the restoration of dynamic stability in the PCL-injured knee

Functional training for the purpose of restoring dynamic joint stability ha s received considerable interest in recent yeats. Contemporary functional t raining programs are being designed to complement, rather than replace, tra ditional rehabilitation protocols. The purpose of this clinical commentary is to present a management strategy for restoring dynamic stability in the posterior cruciate ligament (PCL)-injured knee. The strategy presented inte grates five key concepts: (a) planned variation of exercise, (b) outcomes-b ased assessment, (c) kinetic chain exercise, (d) proprioception and neuromu scular control, and (e) specificity of activity. Pertinent research finding s and a clinical rationale are provided for using functional training in th e restoration of dynamic stability in the PCL-injured knee.
