For example, the superior plica is also known as the suprapatellar plica, plica synovialis suprapatellaris, superomedial plica, and medial suprapatellar plica. It has also been called the superomedial plica, a term referring to the frequent location of this synovial fold along the medial side of the suprapatellar pouch. View larger version (187K).
Suprapatellar plica syndrome was considered when (1) the patient complained of anterior knee pain and had localized tenderness above the suprapatellar pouch, (2) magnetic resonance imaging revealed.
The suprapatellar plica is found in the suprapatellar pouch, an area behind the kneecap extending up behind the quadriceps tendon. The suprapatellar plica is typically a domed, crescent shape, sitting between the suprapatellar bursa and the knee joint, and may be connected to part of the medial plica.MRI confirms that the unusual appearance of the suprapatellar pouch of the knee on ultrasound is due to a complete suprapatella plica entrapping fluid, producing localized synovitis and distorting the quadriceps fat pad. There is minor central quadriceps insertional tendinosis.The synovial plica of the knee joint is considered a remnant of the septum that existed in the patellofemoral joint during fetal life.1 The synovial plica is classified into four distinct anatomic patterns: superior, medial, inferior, and lateral. In particular, a medial patellar plica is called a “shelf” and is a well-known disease.2 A suprapatellar plica, which is little known, divides.
The suprapatellar plica is seen in several forms in adult patients, with a prevalence of 89% at autopsy (10). At MR imaging, the suprapatellar plica is best visualized on a sagittal view as a bandlike low-signal-intensity structure posterior to the patella (Fig 3). At arthroscopy, a complete suprapatellar plica (Fig 4) is suggested only by the presence of a short suprapatellar pouch. The.Read More
Figure 2: Schematic image of the Sakakibara classification Type B mediopatellar plica, lateral plica, and cord-like structure complex located in the suprapatellar pouch of the knee. The suprapatellar plica has been described as a synovial fold in the suprapatellar pouch of the knee joint that is present in approximately 20% of the population. This fold can become symptomatic after injury and.Read More
Results: The suprapatellar plica was present 73.8% and classified into 6 types which were arch type, medial type, lateral type, perforated type, pillar type and complete type. The medial synovial.Read More
From June 1991 to March 1993, 400 knees in 363 patients were studied arthroscopically to clarify the arthroscopic anatomy of the plica and determine the classification of the plica. The various patterns of the synovial plicae were classified according to their shape and size from the arthroscopic view. Incidences of the synovial plica at the knees were: suprapatellar plica, 87.0%.Read More
OBJECTIVE. Injury to the infrapatellar plica (ligamentum mucosum) has not been previously described in the radiology literature to our knowledge. This article shows the MR imaging appearance of inj.Read More
Their classification is based on the location as lateral, mediopatellar, suprapatellar, and infrapatellar. Mediopatellar plica is commonly symptomatic. The purpose of this study was to identify magnetic resonance (MR) characteristics of the medial plica and to correlate with arthroscopy for cause confirmation in patients with painful knee. Materials and Methods: The current study was.Read More
Classification of each other type of plica becomes confusing because each one has multiple sub-groups. It is important to know that the suprapatellar plica does have attachments to the quadriceps tendon and depending on the size and shape, may create impingement between the patellar tendon and femoral trochlea in the range of 70-100 degrees of knee flexion. Similarly, the medial patellar plica.Read More
Terminology. The term is generally used interchangeably with suprapatellar pouch, but really it is only when the suprapatellar plica forms a complete septum and splits the pouch in two that a distinct bursa exists. If excessive fluid forms in this bursa it may be called a suprapatellar cyst.Read More
Synovial plicae are normal anatomical structures of the knee that may become symptomatic. MRI is an established technique for evaluating the anatomy of the knee, and it is a valuable tool for detecting plicae because of its high resolution resulting in increased tissue characterisation. At MRI, knee plicae appear as low-signal-intensity structures of variable size and thickness, and they are.Read More
In arthroscopic studies, its prevalence has been reported between 18% and 80% in various studies and different results have been presented.(4,5) Medial plica starts from the suprapatellar plica or medial joint wall, the oblique moves along the wall, and ends on the level of the infrapatellar fat pad. Plica has a flexible structure, glide on the femur condyles, and are generally asymptomatic.Read More
