6-year follow-up of 84 patients with cartilage defects in the knee : knee scores improved but recovery was incomplete
Løken, Sverre; Heir, Stig; Holme, Ingar Morten K.; Engebretsen, Lars; Årøen, Asbjørn (Journal article; Peer reviewed, 2010-10)Background and purpose: The natural history of focal cartilage injury is largely unknown. In this study we investigated 6-year outcomes in patients with arthroscopically verified, focal, fullthickness cartilage injuries ... -
Autologous chondrocyte implantation to repair knee cartilage injury : ultrastructural evaluation at 2 years and long term follow up including muscle strength measurements
Løken, Sverre; Ludvigsen, Tom C.; Høysveen, Turid; Holm, Inger; Engebretsen, Lars; Reinholt, Finn P. (Journal article; Peer reviewed, 2009-07-02)Autologous chondrocyte implantation (ACI) usually results in improvement in clinical scores. However, long-term isokinetic muscle strength measurements have not been reported. Biopsies from the repair tissue have shown ... -
Bone marrow mesenchymal stem cells in a hyaluronan scaffold for treatment of an osteochondral defect in a rabbit model
Løken, Sverre; Jakobsen, Rune B.; Årøen, Asbjørn; Heir, Stig; Shahdadfar, A.; Brinchmann, J. E.; Engebretsen, Lars; Reinholt, Finn P. (Peer reviewed; Journal article, 2008-07-01)The purpose of this study was to evaluate the efficiency of using mesenchymal stem cells (MSC) in a hyaluronan scaffold for repair of an osteochondral defect in rabbit knee. Bone marrow was harvested from the posterior ... -
Intraarticular location predicts cartilage filling and subchondral bone changes in a chondral defect
Heir, Stig; Årøen, Asbjørn; Løken, Sverre; Sulheim, Steinar; Engebretsen, Lars; Reinholt, Finn P. (Journal article; Peer reviewed, 2010-10)Background and purpose: The natural history of, and predictive factors for outcome of cartilage restoration in chondral defects are poorly understood. We investigated the natural history of cartilage filling subchondral ... -
Microfracture technique versus osteochondral autologous transplantation mosaicplasty in patients with articular chondral lesions of the knee: a prospective randomized trial with long-term follow-up
Ulstein, Svend; Årøen, Asbjørn; Røtterud, Jan Harald; Løken, Sverre; Engebretsen, Lars; Heir, Stig (Journal article; Peer reviewed, 2014-01-21)Purpose: To compare long-term functional and radiological outcome following microfracture technique (MF) versus osteochondral autologous transplantation (OAT) mosaicplasty for treating focal chondral lesions of the ... -
No degeneration found in focal cartilage defects evaluated with dGEMRIC at 12-year follow-up
Engen, Cathrine Nørstad; Løken, Sverre; Årøen, Asbjørn; Ho, Charles; Engebretsen, Lars (Journal article; Peer reviewed, 2016-11-24)Background and purpose: The natural history of focal cartilage defects (FCDs) is still unresolved, as is the long-term cartilage quality after cartilage surgery. It has been suggested that delayed gadolinium-enhanced ...
