articular capsule of the knee joint
The articular capsule of the knee joint (commonly referred to as capsular ligament) is wide and lax; thin in front and at the side; and contains the patella ("knee cap"), ligaments, menisci, and bursae.〔Platzer (2004), p 206〕 The capsule consists of a synovial and a fibrous membrane separated by fatty deposits anteriorly and posteriorly.〔Platzer (2004), p 210〕
== Synovial membrane ==
Anteriorly, the reflection of the synovial membrane lies on the femur; located at some distance from the cartilage because of the presence of the suprapatellar bursa. Above, the reflection appears lifted from the bone by underlying periosteal connective tissue.〔 In a standing posture, the suprapatellar bursa is seemingly redundant. It is however also referred to as the ''suprapatellar synovial recess'' as it gradually unfolds as the knee is flexed; to open up completely when the knee is flexed 130 degrees.〔''Thieme Atlas of Anatomy'', pp 400-401〕 The suprapatellar bursa is prevented from being pinched during extension by the articularis genus muscle. On the tibia, the anterior reflection and attachment of the synovial membrane is located near the cartilage.〔
Anteriorly, the infrapatellar fat pad is inserted below the patella and between the two membranes. It extends from the lower margin of the patella above, to the infrapatellar synovial fold below. With its free upper margin, this fold extends dorsally through the joint space to surround the two cruciate ligaments from the front, thus dividing the surrounding joint space into two chambers. Laterally of this are a pair of alar folds.〔
Posteriorly, the femoral attachment of the synovial membrane is located at the cartilaginous margin of the lateral and medial femoral condyles, why the joint space has two dorsal extensions. Between these, the synovial membrane passes in front of the anterior and posterior cruciate ligaments, why these ligaments are both intracapsular and extra-articular with their tibial attachment located exactly on the cartilage margin. Both the lateral and medial meniscus are, however, located within the synovial capsule.〔
