What is the ligamentum mucosum?
The ligamentum mucosum (LM), or infrapatellar plica, is a non-isometric structure of the knee joint that traverses from the intercondylar notch of the femur to the infrapatellar fat pad.
What is plica in the knee?
A plica is a fold in the membrane that protects your knee joint. Most people have four folds in each knee. Sometimes the plica located in the middle of your knee becomes irritated. This is called plica syndrome and it’s characterized by pain, swelling and instability.
What is Infrapatellar plica?
The infrapatellar plica, or ligamentum mucosum, is the most common plica in the knee. It is a normal structure, formed at approximately the 8th to 12th weeks of gestation, that is present when the primitive embryologic septum between the medial and lateral compartments of the knee does not completely regress.
How do I get rid of knee plica?
Knee plica problems usually get better without surgery. You’ll need to rest your knee for a while and put ice on it. Your doctor may suggest anti-inflammatory pain medicine, like ibuprofen or naproxen, and stretching your leg muscles, especially your quadriceps and hamstrings.
How long does it take for plica to heal?
Most cases of plica syndrome respond well to physical therapy or a home exercise program. These usually involve stretching your hamstrings and strengthening your quadriceps. Most people start to feel relief within six to eight weeks of starting a physical therapy or exercise program.
What is the Hoffa fat pad?
Hoffa’s (infrapatellar) fat pad (HFP) is one of the knee fat pads interposed between the joint capsule and the synovium. Located posterior to patellar tendon and anterior to the capsule, the HFP is richly innervated and, therefore, one of the sources of anterior knee pain.
Can plica come back?
Of note the plica may grow back after excision but is usually not symptomatic any longer. A plica is an embryonic remnant commonly present in the population. Normally it consists of a thin, vascular, pliable band of tissue that originates from the synovial wall and crosses the synovial joint.
How do you fix plica syndrome?
What is Suprapatellar plica?
The suprapatellar plica, also referred to as the plica synovialis suprapatellaris, superior plica, supramedial plica, medial suprapatellar plica or septum is a domed, crescent shaped septum that generally lies between the suprapatellar bursa and the tibiofemoral joint of the knee.
