The knee is a complex structure subjected to heavy repetitive loads. It is no surprise that the joint is frequently injured, prompting the need for expert advice on how to rehabilitate it. The optimum treatment of knee injuries depends on thoroughly examining the anatomy and biomechanics to identify structural and functional impairments. In rehabilitation, any intervention should be tailored based on the patient’s specific impairments to optimize functional progression and to avoid recurrent injuries. Although exercise rehabilitation for knee injuries has been well illustrated for various acute and chronic conditions, its use can be controversial in the literature. Controversies can primarily concern the type and timing of exercise performed in rehabilitating knee injuries. The most discussed issues in the rehabilitation of knee injuries are the type and timing of exercise performed. Not only does this section incorporate current exercise rehabilitation, but it gives detailing/illustrating injury spesific rehabilitation exercises. It is hoped that the reader will find these more focused, practical applications helpful.
