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.
