The knee joint is the largest joint in the human body and consists of three bones, the movements of which are guided exclusively by muscles, ligaments and tendons. Two crescent shaped cartilaginous discs are located between the femoral bone and the tibial bone on the inner and outer sides of the knee joint. These discs distribute the load on the joint over a large area and act as a buffer or shock absorbing system. Their structure is clearly different from that of the articular cartilage. The latter is a 1-2mm layer that covers the entire bone surface within the joint. An elastic and aqueous tissue, the articular cartilage provides a low friction gliding surface. Injury or damage to these structures is often irreparable and can, over the medium to long term lead to articular wear, better known as arthritis. The knee joint is divided into three compartments: The medial femoral condyle and medial surface of the tibia The lateral femoral condyle and lateral surface of the tibia. The deep surface of the patella and the corresponding surface of the front of the patella.

Is é an comh glúine an comhpháirteach is mó i gcorp an duine agus tá sé comhdhéanta de thrí cnámha, na gluaiseachtaí a threorú go heisiach ag matáin, ligaments agus tendons. Dhá Crescent dioscaí loingeánacha múnlaithe suite idir an cnámh femoral agus an cnámh tibial ar an taobh istigh agus amuigh ar an comhpháirteach glúine. Is é an struchtúr soiléir difriúil ó na cartilage articular. , Soláthraíonn an cartilage articular a cuimilte íseal gliding dromchla. Tá díobháil nó damáiste do na struchtúir seo go minic irreparable is féidir agus, thar an meántéarma agus mar thoradh fadtéarmach a chaitheamh articular, níos fearr ar a dtugtar airtríteas. Is é an comh-glúine roinnte ina trí urrainn: An dromchla medial condyle agus medial femoral an tibia An dromchla cliathánach condyle agus cliathánach femoral an tibia. An dromchla ucht an patella agus an dromchla chomhfhreagracha de na tosaigh ar an patella.
