Abstract

Introduction: The aim of this paper is to get the surgeon familiar with black cartilage and massive synovitis while performing a total joint replacement operation including preoperative, intraoperative and postoperative tips and pearls. Case presentation: Two Caucasian male patients, one with knee osteoarthritis and one with both knee and hip osteoarthritis. Conclusion: The black cartilage and softened bone does not heal different from the normal bone, therefore internal fixation of the fractures and cement less fixation of the prosthesis will not fail. Caution should be paid for excessive bleeding after total synovectomy. Patients have to be informed about consecutive operations and recurrent postoperative effusions.
