Plica surgery in the knee is performed to remove a plical fold of joint lining that is being troublesome, perhaps because it is catching in the joint. The procedure is usually arthroscopic (keyhole).

Surgery for plica syndrome

Surgery may be indicated when the patient repetitively experiences symptoms, which may include:

  • inflammation of a plica, due to an impact injury
  • nipping of a mediopatellar plica between femur and patella
  • nipping of a suprapatellar plica between femur and the quads tendon
  • inflammation of the Hoffa fat pad, when a tethered infrapatellar plica is subjected to increased stresses, such as with an adolescent growth spurt
