| description | 【Abstract】 A case of swelling and anterior painful
knee due to tear of mediopatellar plica is reported. The patient
also felt clunk of the patellofemoral joint and knee
locking. Under arthroscopic examination, a thick and fibrous
plica was found medial to patellar, and a bucket tear along
the plica from medial patellar retinaculum to infrapatellar fat
pad. Polarized microscopic examination showed collagen
fiber fragment and loss of light reflecting property. Neuroimmunohistology
suggested up-regulation of synovial plica
innervation in the area around the crack. This may be related
to the pain. The bucket tear of mediopatellar plicacaused
pain and lock of knee are more common than previously
reported.
