Knee stiffness explained by a neglected giant synovial chondromatosis (Historical case)

Synovial chondromatosis of the knee is a benign synovial dystrophy characterized by the formation of cartilaginous nodules (chondromas). Their early diagnosis and treatment are primordial to preserve the joint and prevent its degeneration. Its treatment remains controversial, adopting many attitudes, arthroscopic chondromas extraction or arthrotomy, arthroscopic synovectomy, high tibial osteotomies or even a prosthetic replacement. The literature reports many sporadic cases of synovial chondromatosis of the knee each one with its clinical and therapeutic particularity ; In this sense we report our historical case of giant synovial chondromatosis neglected source of knee stiffness, operated by open surgery bothly anterior and posterior approachs allow to extract 600 grams of chondromas agglomerated into several diffuse masses.
