Active clinical trials for "Osteochondritis Dissecans"

The purpose of this study is to evaluate the safety and effectiveness of using Chondro-Gide® collagen membrane either sutured or glued compared to microfracture alone in the treatment of symptomatic cartilage defects of the knee.

The purpose of this study is to compare the functional, clinical and radiographic outcomes associated with trans-articular drilling versus retro-articular drilling, two commonly employed techniques of operative treatment for stable forms of juvenile osteochondritis dissecans (JOCD) lesions. This study also aims to better define the natural history of this condition in its most commonly identified pathological state (as a stable lesion) following surgical intervention by determining the rate of radiographic healing and any need for secondary surgery.

This study is an observational study to test and validate a questionnaire and statistical model used to determine patient preferences regarding treatment for any one of 11 musculoskeletal conditions: hip arthritis, knee arthritis, hip labral tears and femoroacetabular impingement (FAI), osteochondritis dissecans, Achilles tendon rupture, patellofemoral dislocation, distal radius fracture, and fractures of the hip, ankle, tibia, and proximal humerus. This study aims to understand how multiple treatment variables, including pain, rehabilitation time, cost, and choice of surgical versus non-surgical intervention, impact patients' decision-making processes and ultimate choice of treatment.

This is a 1:1 randomised pilot study in 30 patients in 1 site in Helsinki, Finland. The investigators hypothesize that function, pain, type and quality of cartilage in adult patients with osteochondritis dissecans of the knee will be better in the DBX group compared to the mosaicplasty group.

In this study,the Autologous chondrocyte implantation (ACI)technology and cell sheet technology are used to Cells Sheet-Autologous Chondrocyte Implantation(CS-ACI) for treating Cartilage Defects.The Safety and Efficacy Study of CS-ACI are evaluated.

Background: Matrix-associated autologous chondrocyte implantation (MACI) has been recently used to treat cartilage defects. The investigators had previously developed a biphasic osteochondral composite as the construct for chondrocyte implantation. The investigators further conducted this feasibility study of such device to treat patients with osteochondral lesion of the knee joints.

The purpose of this pilot study is to investigate the efficacy and safety of autologous transplantation, under arthroscopy, of Bone Marrow Mesenchymal stem cells, using, with a cell separator, a fresh non-culture expanded Autologous Bone Marrow derived Mesenchymal Stem, mixed and activated with proteins scaffold in patient with Knee cartilage defects and osteoarthritis. Based on extensive preclinical investigations, the technology of using freshly isolated bone marrow mononuclear cells mixed with proteins seems safe and most effective for a one-step correction of cartilage defect and restoration of the osteochondral complex, because the same mixture can generate cartilage in the vasculature-free knee joint, and bone in the environment of bone defects.

The rationale for this research study is to evaluate the effect on clinical outcomes of weight bearing as tolerated after forage surgery for the treatment of osteochondral defects of the ankle, thus potentially eliminating the need for a period of immobilisation or non-weight bearing after surgery. The investigators hypothesize that their will be no difference in functional outcomes between weight bearing as tolerated as compared to non-weight bearing for six weeks after forage surgery for OCD of the ankle.

The Cartilage Autograft Implantation System (CAIS) is a single-stage procedure in which cartilage is harvested from non-critical regions of articular cartilage, but then immediately morcellated and loaded onto a polymer membrane-scaffold, which is subsequently used to fill the chondral defect. The autograft-membrane composite is fixed to the defect with a biodegradable staple. The investigators aim to evaluate this new technique through a pilot clinical trial involving 36 patients randomized into microfracture and CAIS treatment arms (randomisation ratio 1:2), with a minimum follow-up of 1 year, using both clinical and radiological (magnetic resonance imaging) outcomes. If the results of this pilot trial are successful, the investigators plan to expand the study by recruiting more patients to achieve a suitably-powered trial. Primary hypothesis 1: That functional scores will increase by at least 0.5 SD over pre-operative values, by 1 year following the CAIS procedure Primary hypothesis 2: That articular cartilage height will have a sustained increase of at least 2 mm at 1 year following the CAIS procedure Primary hypothesis 3: That functional scores in the CAIS group will be equivalent or superior to those in the microfracture group

Osteochondral defects (OCD) of the talus are pathologic lesions of the talar cartilage and its subchondral bone and might severely deteriorate the quality of life. For the treatment of multiple and/or large talar OCDs and in patients with failed previous surgical treatment the Ankle Spacer was developed. Six patients are included in a prospective clinical and radiological study with a follow-up of two years.
