Meniskusimplantate: Indikationen und Ergebnisse

Introduction: Meniscal scaffolds represent an attractive surgical option for patients with persisting symptoms following partial meniscectomy.Methods: Two different scaffolds are currently approved and available for clinical use in Europe: the Collagen Meniscus Implant (CMI®; Ivy Sports Medicine GmbH., Gräfelfing, Germany), a porous collagen-glycosaminoglycan (GAG) matrix of defined geometry, composed of about 97 % purified type I collagen; and the Actifit® Implant (Orteq Ltd., London, UK), a synthetic polymeric scaffold composed of 80 % biodegradable polyester and 20 % polyurethane.Results: With strict observation of the correct differential indications, good/excellent improvement of knee function and increased sports activities can be expected in 70–90 % of patients. Additional pathologies, such as chondral degeneration, instabilities and malalignments must be considered.Conclusion: Although a wide range of conditions could potentially be treated, good results are strictly dependent on close observation of the correct indications.An english version of this article is available as electronic supplemental material under dx.doi.org/10.007/s00142-014-0837-5.
