title: [Clinical diagnostic standard of mediopatellar plica syndrome].
abstract: OBJECTIVE
  To increase the level of clinical diagnosis of mediopatellar plica syndrome.
  
  
  METHODS
  We reviewed the preoperative clinical symptoms of 67 knee joints that were proved to have pathologic mediopatellar plica by arthroscopy.
  
  
  RESULTS
  Mediopatellar plica syndrome had the following clinical symptoms: painful knee and mediopatellar tenderness in all patients; tender bands in 56.7% patients; positive test of flexion or extension with internal femoral condyle pressed in 62.7% patients; positive Mcmarry's sign in 31.3% patients.
  
  
  CONCLUSIONS
  The clinical diagnostic standard of mediopatellar plica syndrome is that the first above-mentioned clinical symptom plus one of other three symptoms could suggest the diagnosis, while the first clinical symptom plus two or three of other three symptoms could define the diagnosis.
