Complete suprapatellar plica is a rare congenital anomaly that separates the suprapatellar bursa from the knee joint cavity. Although the pathological incidence of this condition is not known, it can cause patellofemoral symptoms, anterior knee pain, and rarely hemarthrosis. We report a patient with a hematoma in an unusual location just three weeks after an arthroscopic procedure, associated with a complete suprapatellar plica undetected during primary surgery. The hematoma was not in the synovial cavity, rather between the quadriceps tendon and the synovial membrane and presenting with pain and catching. This unusual location has not been reported before. Repeat arthroscopic surgery with drainage of hematoma and plica resection relieved the symptoms.
完全性髌上皱襞是一种罕见的先天性异常，它将髌上囊与膝关节腔分隔开。尽管这种情况的病理发生率尚不清楚，但它可导致髌股症状、膝前疼痛，很少引起关节积血。我们报告一例患者，在关节镜手术后仅三周，在一个不寻常的位置出现血肿，与初次手术时未发现的完全性髌上皱襞有关。血肿不在滑膜腔内，而是位于股四头肌腱和滑膜之间，表现为疼痛和卡顿。这种不寻常的位置以前未见报道。再次进行关节镜手术，引流血肿并切除皱襞后症状缓解。
