NCT00560664
Numerous surgical techniques have been developped for the treatment of chondral and osteochondral defects of the knee. Among those techniques autologous chondrocyte transplantation (ACT) was promising but have potential drawbacks. A novel development by TBF is available. The aim of this randomized trial is to compared this new ACT technique to mosaicoplasty. Final outcomes were measured at 2 years using clinical evaluation scoring system (International Knee Documentation Committee), MRI and arthroscopy with biopsy. 64 patients are needed to detect a mean IKDC difference of at least 15 points with 90% power at a 5% alpha level. Twelve surgical centers in France are involved.
NCT03909139
Femoro-acetabular impingement is a well known cause of damage to the acetabular labrum and chondrolabral junction. Additionally, it has been proposed that disruption of hip biomechanics resulting from a labral tear causes a faster progression towards osteoarthritis (OA). This progression has been observed to begin with breakdown of the chondrolabral junction with later development of diffuse osteoarthritis. Use of hip arthroscopy has increased dramatically in recent years to treat symptomatic labral tears and potentially avoid the morbidity and cost associated with hip osteoarthritis. Correction of labral pathology presents a technical challenge and many techniques currently exist. Increased understanding of the structure-functional relationship dictated by labral anatomy has led to the development of methods aimed at restoring functional anatomy by re-establishing the labrum's native position and contour on the rim of the acetabulum. Therefore, akin to repairing a torn meniscus in the knee, restoring the anatomic footprint of a torn labrum will reconstitute normal joint biomechanics. Despite the advances in techniques for labral repair, strategies for mitigating or repairing damage to the chondrolabral junction do not yet exist. This area has been shown to consist of hyaline and fibro cartilage. Many techniques for cartilage repair exist, although most are not feasible due to technical challenges specific to the hip joint. The management of articular cartilage defects is one of the most challenging clinical problems for orthopaedic surgeons. Articular cartilage has a limited intrinsic healing capacity, and pathology frequently results in gradual tissue deterioration. Currently, the standard surgical intervention for end-stage degenerative joint pathology is total joint replacement. Early surgical interventions for symptomatic cartilage lesions including cell based therapies such as autologous chondrocyte implantation (ACI), bone marrow aspirate concentrate (BMAC) implantation, or microfracture have been suggested to restore normal joint congruity and minimize further joint deterioration. Techniques such as ACI, which have been successfully used in the knee joint, have limited application in the hip due to the technical difficulties of open procedures.
NCT02503228
With institutional review board approval and informed consent, patients are prospectively enrolled into a registry to follow outcomes after osteochondral allograft (OCA) and/or meniscal allograft transplantation. Patients are included when 1 year followup data are available, including complications and reoperations, patient reported outcome measures (PROMs), compliance with rehabilitation, revisions, and failures. In addition, MOPS grafts are compared to standard preservation grafts, and unipolar, multisurface, and bipolar cohorts, as well as patient compliance variables, are compared.
NCT06915363
The goal of this randomized controlled clinical trial is to demonstrate the safety and effectiveness of the BioPoly® Partial Resurfacing Knee Implant for the treatment of cartilage defects of the distal femur in adult patients with knee pain and symptoms who are candidates for surgical intervention of the knee compared to outcomes for the control group. The primary effectiveness endpoint is Month 24 composite clinical success (CCS) defined by: * no secondary surgical intervention (SSI) and * an improvement from baseline in the Knee injury and Osteoarthritis Outcome Score (KOOS) total score (scaled 0 to 100) of at least 10 points. Researchers will compare the CCS for the investigational device group to a control group receiving the standard of care, either microfracture or debridement). Subjects randomized to the investigational group will receive the BioPoly Knee device and those randomized to the control group will receive the current standard of care, either microfracture or debridement.
NCT04840147
The aim of the study is to compare whether JointRep® plus microfracture is more effective than microfracture alone when treating symptomatic focal articular cartilage lesions in the knee (femoral condyles or trochlea).
NCT04364334
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.
NCT03777735
This observational study is to document the application of a human bone graft in the surgical repair of bone fragment detachment in the knee joint (osteochondral defect) and its subsequent healing process.
NCT05124613
The Covid-19 pandemic has led to the postponement and cancellation of elective orthopaedic surgeries worldwide. These delays to elective procedures combined with ongoing demand have led to increasingly longer waiting list times. This cross-sectional pilot study aims to investigate the change in patients' perceptions of knee pain and function since being waitlisted for surgery. A bespoke survey will be administered to eligible patients over the phone from Trafford General Hospital, Manchester. The survey will also investigate the coping mechanisms and the preventative measures patients are taking to manage symptoms during the pandemic, and question what kinds of communication and support patient would like to be offered whilst waiting for treatment. This study will improve clinicians' and researchers' understanding of how patients are coping with symptoms during this pandemic, and provide information on how to better support patients who are waiting for knee surgery. This information could be used to enhance orthopaedic care during, and in the aftermath, of this pandemic. The information gathered in this study may also be used to inform a larger multi-centre study.
NCT03036878
To evaluate the use of ReNu™ allograft for the augmentation of marrow stimulation for osteochondral lesions
NCT03371121
Aim of the study is to evaluate clinical and radiographic outcomes in patients undergone all-arthroscopic autologous matrix induced chondrogenesis for symptomatic osteochondral talar lesions
NCT01791062
The two-layer bioresorbable HYTOP® matrix consists of an upper layer of highly purified porcine splint-skin which contains natural pores, and a lower layer of highly purified collagen fleece containing hyaluronan (HA). In this study, the medical device will be used and evaluated in a one-step procedure combining microfracturing with surgical implantation of HYTOP®. HYTOP® will support haemostasis in the articular cartilage defect, act as a support for cell growth and as a three-dimensional scaffold for cell differentiation. HYTOP® will protect the underlying tissue after cartilage debridement and/or microfracturing of the subchondral bone. The primary working hypothesis is that HYTOP® is safe and suitable as a cell-free matrix to support haemostasis, as a cover for the cartilage lesion and eventually to enhance cartilage regeneration in a one-step surgical procedure.

CARTIPATCH® is an Autologous Chondrocyte Implantation product including functional cells in a matrix, indicated for the treatment of isolated osteocartilaginous lesions. The submitted protocol is a Phase III multicentric, prospective, controlled and randomized clinical trial, sponsored by TBF Génie Tissulaire, France. The main objective of the protocol is to compare the clinical improvement of the IKDC subjective score between the microfracture-treated group and the CARTIPATCH® chondrocyte graft-treated group , 18 months following surgery. Several secondary objectives were determined. The microfracture procedure will be conducted in one operative step, during arthroscopy and CARTIPATCH® procedure will be conducted in two operative steps: 1. Arthroscopy to collect cartilage; 2. Implantation following arthrotomy about 6 weeks following arthroscopy. Both groups will follow the same rehabilitation program.
