ACI-C Versus AMIC. A Randomized Trial Comparing Two Methods for Repair of Cartilage Defects in the...

Osteochondritis DissecansOsteoarthritis2 more

ACI-C versus AMIC: A controlled randomized trial comparing Autologous Chondrocyte Implantation ( ACI) and Autologous Matrix Induced Chondrogenesis (AMIC) for repair of cartilage defects in the knee. Eighty patients (Forty in each group) having symptomatic cartilage defects in their knee are planned to include in this study. Both techniques will use the ChondroGide membrane from Geistlich to cover the defects. ACI includes an arthroscopy to harvest cartilage for cell cultivation in our lab located in Tromso. 3-4 weeks later using a mini arthrotomy the cells will be implanted under the ChondroGide membrane. The AMIC group will be listed for a mini arthrotomy, cleaning of the defect, microfracture and cover of the defect using the same ChondroGide membrane. In both groups stitches and fibrin glue will be used to fix the membrane. Inclusion criteria: Age between 18-60, Informed consent signed by patient, Symptomatic cartilage defect. Size more than 2 square cm. Exclusion criteria Alcohol or drug abuse during the last three years, Inflammatory joint disease, Serious illness Preoperative examination and follow up: Clinical examination and registration of KOOS (a validated knee score), VAS (visual analog pain scale) and Lysholm knee score. Radiographs of the involved knee including weightbearing standing radiographs of both knees. Kellgren- Lawrence classification will be used for grading of OA. Patients will be checked after 1, 2, 5 and 10 years following surgery. Symptomatic patients having a new cartilage resurfacing operation or prosthesis will be listed as failures of the initial treatment. Hypothesis: AMIC will be equal to ACI, and if that is the case this would be a benefit for the patients and the society. AMIC is much cheaper compared to ACI (needing an expensive cell cultivation and two surgeries). Data will be analyzed using the SPSS statistical package.

Knee Registry (Knieregister)

Knee PathologyOsteoarthritis4 more

Rationale: In view of patient care, patient characteristics and treatment parameters are registered for all patients visiting the Mobility Clinic of the University Medical Center Utrecht for orthopaedic knee treatment. Patients also fill out questionnaires for function, pain and mobility of the knee, before and after treatment. Objective: The main objective of this registry is to collect patient characteristics and treatment parameters together with data from the questionnaires in a database. This knee registry can be used for future research questions. Study design: This is a longitudinal observational registry. Study population: All patients that visit the Mobility Clinic will be asked to participate in the knee registry. Patients that meet one or more of the following criteria will be excluded: are below the age of 16, not able or willing to sign the broad consent form, not being able to read and understand Dutch language, or receiving medical treatment for their knee elsewhere. Main study parameters/endpoints: Data will be collected for future research for which the purpose is not known at this time. When new research will be conducted, study parameters will be set. A study application has to be submitted to the institutional ethical review board of the University Medical Center Utrecht. Patients do not need to be asked permission for the use of their data for each study individually. Only when additional information is needed. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The burden for patients to participate in this registry is minimal and consists of time. Any future results may be beneficial for patients. Participation or refusal to participate in the registry has no consequences for their treatment.

Prognostic Analyses on a Validation Series of Patients With Waldenström's Disease

Waldenstrom's DiseasePrognostic Index

Waldenström's macroglobulinemia (WM) is defined by the association of bone marrow lymphoplasmocytic infiltration and monoclonal immunoglobulin M (IgM). A mutation in the MYD88 gene is found in up to 90% of patients, and a mutation in the CXCR4 gene in approximately one third of patients. Treatment should be initiated in cases of cytopenia, bulky disease or when the physicochemical or immunological properties of IgM explain the occurrence of amyloidosis, cryoglobulin, neurological manifestations, or hyperviscosity syndrome (due to the presence of a large amount of IgM). However, approximately 30% of patients are diagnosed without any symptom and therefore they do not meet the criteria for initiating treatment. At the time of initiation of the first treatment, the prognosis is usually estimated with the International Prognostic Index (IPSSWM) which is based on five variables: age, platelet count, haemoglobin concentrations, β2-microglobulin and monoclonal component concentration. Serum albumin and lactate dehydrogénase (LDH) levels also retain a prognostic role and these two characteristics have been incorporated in a proposal for a revision of this index. Improving prognostic assessment at the time of the first treatment initiation and taking into account the prognostic impact of events occurring in the course of evolution, should improve the strength of treatment decision at the time of initial treatment and during the follow-up. It should also help to design clinical trial for fast and effective evaluation of new treatments. Our work should also help to adjust clinical monitoring of asymptomatic patients. Prospective and retrospective multicenter prognostic study with a descriptive objective, associated with a biological collection appropriately annotated and stored. A retrospective series including 470 patients with symptomatic WM is already available. The follow-up of these patients will be updated and an additional series of 250 symptomatic patients will be prospectively enrolled. 250 asymptomatic patients will be also enrolled.

Psychological Response and Readiness Associated With OCD of the Knee

Osteochondritis Dissecans KneePsychological Stress

This study primarily aims to determine whether patients diagnosed with osteochondritis dissecans (OCD) of the knee experience psychological stress due to their diagnosis and treatment plan. Secondarily, this study aims to determine whether knee OCD patients experience a change in stress and depression as they progress through their standard-of-care treatment plan, and whether they have impaired psychological readiness for return to sport.

Defect of Articular CartilageOsteochondritis Dissecans

The Cartilage Autograft Implantation System (CAIS) is designed as a single surgical treatment of damaged knee cartilage using the subject's own healthy cartilage obtained from a non-weight or low weight-bearing region. CAIS is indicated for the repair of articular cartilage lesions and osteochondritis dissecans (OCD) of the knee through cartilage regeneration.

The purpose of this study is to evaluate preoperative objective measurements and operative objective measurements to determine if there is any effect to postoperative outcomes. Patients who were 13 years old or greater at the time of arthroscopic osteocapsular release were followed clinically and radiographically to determine best practice and optimal treatment and technique, risk and rate of complication, and postoperative outcomes.
