Fixation of osteochondral fragments in the human knee using Meniscus ArrowsÂŽ
The aim of this study is to compare the hold in bone of Meniscus ArrowsÂŽ and Smart NailsÂŽ, followed by the report of the results of the clinical application of Meniscus ArrowsÂŽ as fixation devices. First, pull-out tests were performed to analyse the holdfast of both nails in bone. Statistical analysis showed no significant difference; therefore, the thinner Meniscus ArrowÂŽ was chosen as fixation device in the patient series of two patients with a symptomatic Osteochondritis dissecans fragment and three patients with an osteochondral fracture of a femur condyle. The cartilage margins were glued with TissuecollÂŽ. All fragments consolidated. Second look arthroscopy in three patients showed fixed fragments with stable, congruent cartilage edges. At an average follow-up period of 5Â years no pain, effusion, locking, restricted range of motion or signs of osteoarthritis were reported. Based on the results of the pull-out tests and available clinical studies, Meniscus ArrowsÂŽ and Smart NailsÂŽ are both likely to perform adequately as fixation devices in the treatment of Osteochondritis dissecans and osteochondral fractures in the knee. They both provide the advantage of one stage surgery. However, based on their smaller diameter, the Meniscus ArrowsÂŽ should be preferred for this indication
