Filter by:Non-interventional study to evaluate safety and efficacy of NOVOCART 3D in adult and adolescent patients with full thickness cartilage defects after the treatment with NOVOCART 3D.
The purpose of this study is to evaluate the safety and efficacy of human umbilical cord mesenchymal stem cell(hUC-MSC) for articular cartilage defect of knee.
Subjects will be selected among the investigators' patient population who are already scheduled to receive a marrow stimulating procedure (MSP), with or without the addition of BioCartilage. During the surgical operation for MSP, a portion of the patient's blood is taken out and used to form a patch to cover a cartilage defect of the knee. Currently it is considered standard of care to either form the patch using only a portion of the patient's blood, or form the patch using a portion of the patient's blood combined with an FDA-approved augmentation such as BioCartilage. This study will collect outcomes data and MRI for patients that are undergoing MSP with and without BioCartilage augmentation, then compare the data between those who received BioCartilage and those who did not. The primary endpoint is to determine whether subjects receiving a marrow stimulating procedure (MSP) augmented with BioCartilage have improved outcomes (measured using quality of life indicators, functional outcomes, and MRI) compared to subjects who receive MSP without the use of BioCartilage.
Non-interventional study to evaluate safety and efficacy of NOVOCART® Inject in patients with full thickness cartilage defects in the hip.
The investigators hypothesized that intra-articular injections of Platelet-rich Plasma (PRP) to treat knee degenerative articular cartilage pathology could determine pain relief and recovery of knee function with overall clinical outcome comparable or even better than viscosupplementation, which is a common injective approach applied in this kind of pathology. To this purpose the investigators designed a double blind randomized controlled trial comparing PRP vs viscosupplementation. A power analysis has been performed for the primary endpoint of IKDC subjective score improvement at the 12-month follow-up for PRP. From a pilot study, a standard deviation of 15.2 points was found. With an alpha error of 0.05, a beta error of 0.2 and a minimal clinically significant difference of 6.7 points corresponding at 1/3 of the documented mean improvement, the minimum sample size was 83 for each group. Considering a possible drop out of 15%, 96 patients per group are required for total 192 patients, selected according to well-defined inclusion criteria (see 'Eligibility criteria' section). Patients are then assigned to two different treatment groups, according to a randomization list. The first group of treatment consists of three weekly intra-articular injections of autologous PRP obtained with the following procedure: a 150-ml autologous venous blood sample undergoes 2 centrifugations (the first at 1480 rpm for 6 minutes to separate erythrocytes, and a second at 3400 rpm for 15 minutes to concentrate platelets) to produced 20 ml of PRP. This unit of PRP is then divided into 4 small units of 5 ml each. One unit is sent to the laboratory for analysis of platelet concentration and for a quality test, 3 units are stored at -30° C. The second treatment group consists of patients receiving three weekly injections of hyaluronic acid (Hyalubrix 30 mg/2ml, Fidia Farmaceutici Spa, Italy;Molecular Weight: 1500 kDa). To guarantee the blinding of the patients, all of them undergo blood harvesting to obtain autologous PRP which will be used only in half of them, according to the aforementioned randomization list. One week after the PRP production, the injective treatment starts, with 3 weekly injections of PRP or HA. At the moment of the injection the syringe is properly covered to prevent the patient from discovering the substance he was receiving. After the injection, patients are sent home with instructions to limit the use of the leg for at least 24 h and to use cold therapy/ice on the affected area to relieve pain. During this period, the use of non-steroidal medication is forbidden. Patients are prospectively evaluated basally and at 2, 6, and 12 months of follow-up using clinical subjective scores and objective parameters to determine clinical outcome (see 'Outcome measure' section). Patient satisfaction and adverse events will be also reported. All the clinical evaluations are performed by a medical staff not involved in the injective procedure, in order to keep the study double blinded. At the end of the study, the nature of the injected substance is revealed to the patients.
Induction of autologous repair chondrogenesis to regenerate injured articular cartilage using bone marrow mesenchymal stem cells (MSCs) after in vitro expansion under restricted culturing conditions.
PST (pulsed signal therapy) is a unique form of pulsed electromagnetic field therapy (PEMF) for stimulating healing of damaged structures such as cartilage, bones and soft tissues. The physical effect of the pulsed electromagnetic field (PEMF) has been focus of research in various studies, with cartilage being the most studied, and which has demonstrated an increase in the synthesis of proteoglican and collagen in vitro. This is an randomized, controlled and double blind clinical trial. The main objective is to evaluate clinical improvement regarding anterior knee pain after PST intervention in patients with patellar condropathy.
The purpose of this study is to assess the potential benefit of enhancing knee surgery for cartilage injury using some of the patient's own cells, taken from fat tissue, that may be able to help cartilage to regenerate.
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.
The purpose of this study is to determine how safe a knee injection called Synvisc-One® is in patients with a condition called chondromalacia patella and how well in works in treating the condition. Chondromalacia patella is a common cause of kneecap pain or front knee pain. Often called "Runner's Knee," this condition often affects young, otherwise healthy individuals. Chondromalacia is due to irritation of the undersurface of the kneecap. The undersurface of the kneecap, or patella, is covered with a layer of smooth cartilage. This cartilage normally glides effortlessly across the knee during bending of the joint. In some individuals, the cartilage on the undersurface of the knee cap becomes irritated and soft, resulting in pain. Potential treatments for this condition include rest, injections (numbing or anti-inflammatory medications to reduce swelling and pain), and/or guided strengthening exercises which may help reduce pain. Other Treatments are being evaluated. This study is about Synvisc-One® an experimental device that has been approved by the Food and Drug Administration (FDA) for the treatment of pain in osteoarthritis (OA) of the knee in patients who have failed to respond to treatments that do not involve drugs or surgery and simple pain medication such as acetaminophen. Synvisc-One® is a gel-like substance that, when injected into a joint, acts to lubricate and cushion the joint. Synvisc-One® is made from hyaluronan, which is a molecule that is found normally in joint fluid. Synvisc-One® has not been proven to be safe or helpful in patients with chondromalacia patella (cartilage irritation or softening of the undersurface of the 'knee cap'). So far, this drug/device has been given to over 10,000 people who have knee pain (due to osteoarthritis) and has been proven safe and effective in patients with moderate to severe pain due to knee joint osteoarthritis.
