Bucket-handle tear of medial plica

Plicae are synovial folds, classified according to their anatomical relationship to the patella. The medial patellar plica is normally asymptomatic, but it may cause symptoms when it becomes thickened and fibrotic. We describe three cases of bucket-handle tear of the medial patellar plica. They all suffered from anterior knee pain and clicking. Our cases' symptoms began when they incurred twisting injuries to the knee; therefore, we think that they had an asymptomatic plica first. Pain and clicking began because of the bucket-handle portion rubbed over the medial femoral condyle with knee flexion, and they improved after resection of the bucket-handle portion. Consequently, we think that medial patellar plica can be symptomatic not only when it becomes thickened or fibrotic but also when a bucket handle tear occurs.
