Medial Gutter Knee Compartment

Medial compartment near the middle of the knee on the inner side patellofemoral compartment consisting of the kneecap and part of the femur oa can affect one or more of these compartments.

Medial gutter knee compartment.

The medial collateral ligament or mcl is on the inside of the knee. The arthroscope is brought into the medial compartment. The lateral collateral ligament or lcl is on the outside of the knee. The tibiofemoral joint which is the main hinge joint of the knee occurs where the femur meets the tibia and includes an inner medial compartment and an outer lateral compartment.

Although these braces are intended to produce a valgus directed thrust about the knee joint for the purpose of unloading the medial compartment the mechanisms underlying reported benefits of bracing are unclear at present. The anterior cruciate ligament or acl crosses the joint in the front. Each compartment of the knee should be examined in the standard manner. Inspection of the medial compartment is performed with the knee slightly flexed to allow the scope to enter the compartment over the anterior horn of the medial meniscus.

It may be connected with the suprapatellar plica but more frequently has a separate attachment or occurs in the absence of the suprapatellar plica. The knee should be placed in flexion of approximately 20 to 30 and the valgus force applied to open up the medial compartment. At this point the anteromedial. Walking distance is often reduced with difficulty climbing or descending stairs.

Next the medial compartment is opened by straightening the knee and placing a valgus force on the leg. It is one of the medial patellar stabilizers together with the medial retinaculum and the vastus medialis oblique muscle 5. The mediopatellar plica originates from the medial wall of the knee joint runs obliquely downward and inserts into the synovium covering the infrapatellar fat pad. The medial patellofemoral ligament mpfl belongs to the anterior medial supporting structures of the knee 1 3 and it is the main structure preventing the patella from lateral displacement at 50 60 restraining force 1 7 9.

The suprapatellar pouch the patello femoral compartment the medial gutter the medial compartment the anterior compartment the lateral. Medial compartment osteoarthritis often develops gradually and causes pain over the anteromedial aspect of the knee on weight bearing and exercise.
