An introduction to the plica.

Physical therapy literature has been void of information concerning the plica. The authors discuss the literature available past and present. Using current published information and clinical experience, the authors have described the functional anatomy, the evaluation, the surgery, and the prevention and postoperative rehabilitation programs. Case studies were used to demonstrate conservative and nonconservative approaches in treating the plica syndrome. J Orthop Sports Phys Ther 1982;3(4):171-177.
