Symptomatic Suprapatellar Plica (A Case Report)

Abstract
|
|
|
The plica synovialis is a membranous fold or ridge found in the synovial lining of a joint. Four such plicae are seen with regularity within the human knee joint. Thes3e folds are normal structures that represent remnants of embryonic development of the knee joint. However, when there is inflammation with associated fibrosis, hyalinization and/or calcification of the plica can produce bowstring action causing loss of elastisity resulting in symptomatology vaguely resembling tehose of other
internal derangements of the knee. Controversy exists within the orthopedic community as to whether a suprapatellar plica can develop pathologic changes sufficient to cause disabling knee symptoms.
A 38 years old male patient complained of pain and limitaiton of motion in the right knee. Arthroscopy revealed complete type suprapatellar plica without any evidence of abnormality in the other internal structures. His symptome was completely
relieved after arthroscopic excision of the suprapatellar plica during the follow-up period of 12 months. We believe this can be regrarded as a rare case of suprapatellar plica syndrome and report it as such.
