Knee Injuries Stem Cell Treatment

Stem Cells are being used for Knee InjuriesStem Cell Treatment for knee Injury
Acute knee injury causes pain and swelling with problems bending the knee and taking weight. If the swelling occurs immediately, it can suggest a ligament tear or possible fracture.

If the swelling arises over a period of many hours, meniscal or cartilage injuries may be the cause. .

Longer-term symptoms that point to knee problems will include pain and swelling in addition to other complaints. Inflammation in the joint may be caused by even minor activity.

Giving way, or a feeling of instability of the knee, or, popping or grinding in the knee is associated with cartilage or meniscus tears.

"Locking" is the term used when the knee joint refuses to completely straighten, and this is almost always due to torn cartilage. In this situation, the torn piece of cartilage folds upon itself and doesn't allow the knee to extend.

 

 

Meniscus and Stem Cell Therapy

Regeneration of meniscus cartilage in a knee treated with percutaneously implanted Autologous Mesenchymal Stem Cells.

Mesenchymal Stem Cells are pluripotent cells found in multiple human tissues including bone marrow, synovial tissues, and adipose tissues. They have been shown to differentiate into bone, cartilage, muscle, and adipose tissue and represent a possible promising new therapy in regenerative medicine.

Because of their multi-potent capabilities, mesenchymal stem cell (MSC) lineages have been used successfully in animal models to regenerate articular cartilage and in human models to regenerate bone.

The regeneration of articular cartilage via percutaneous introduction of mesenchymal stem cells (MSC's) is a topic of significant scientific and therapeutic interest.

Current treatment for cartilage damage in osteoarthritis focuses on surgical interventions such as arthroscopic debridement, microfracture, and cartilage grafting/transplant. These procedures have proven to be less effective than hoped, are invasive, and often entail a prolonged recovery time.

We hypothesize that autologous mesenchymal stem cells can be harvested from the iliac crest, expanded using the patient's own growth factors from platelet lysate, then successfully implanted to increase cartilage volume in an adult human knee.

We present a review highlighting the developments in cellular and regenerative medicine in the arena mesenchymal stem cell therapy, as well as a case of successful harvest, expansion, and transplant of autologous mesenchymal stem cells into an adult human knee that resulted in an increase in meniscal cartilage volume.

Mesenchymal stem cells for the treatment of neurodegenerative disease.

Regen Med. 2010 Nov;5(6):933-46

Authors: Joyce N, Annett G, Wirthlin L, Olson S, Bauer G, Nolta JA

Mesenchymal stem cells/marrow stromal cells (MSCs) present a promising tool for cell therapy, and are currently being tested in US FDA-approved clinical trials for myocardial infarction, stroke, meniscus injury, limb ischemia, graft-versus-host disease and autoimmune disorders.

They have been extensively tested and proven effective in preclinical studies for these and many other disorders.

There is currently a great deal of interest in the use of MSCs to treat neurodegenerative diseases, in particular for those that are fatal and difficult to treat, such as Huntington's disease and amyotrophic lateral sclerosis.

Proposed regenerative approaches to neurological diseases using MSCs include cell therapies in which cells are delivered via intracerebral or intrathecal injection. Upon transplantation into the brain, MSCs promote endogenous neuronal growth, decrease apoptosis, reduce levels of free radicals, encourage synaptic connection from damaged neurons and regulate inflammation, primarily through paracrine actions. MSCs transplanted into the brain have been demonstrated to promote functional recovery by producing trophic factors that induce survival and regeneration of host neurons.

Therapies will capitalize on the innate trophic support from MSCs or on augmented growth factor support, such as delivering brain-derived neurotrophic factor or glial-derived neurotrophic factor into the brain to support injured neurons, using genetically engineered MSCs as the delivery vehicles. Clinical trials for MSC injection into the CNS to treat traumatic brain injury and stroke are currently ongoing. The current data in support of applying MSC-based cellular therapies to the treatment of neurodegenerative disorders are discussed.

Increased knee cartilage volume in degenerative joint disease using percutaneously implanted, autologous mesenchymal stem cells.

Pain Physician. 2008 May-Jun;11(3):343-53

Authors: Centeno CJ, Busse D, Kisiday J, Keohan C, Freeman M, Karli D

The ability to repair tissue via percutaneous means may allow interventional pain physicians to manage a wide variety of diseases including peripheral joint injuries and osteoarthritis. This review will highlight the developments in cellular medicine that may soon permit interventional pain management physicians to treat a much wider variety of clinical conditions and highlight an interventional case study using these technologies

Continuous improvement after multiple mesenchymal stem cells transplantations in a patient with complete spinal cord injury. Cell Transplant. 2015 Mar 24; Authors: Danuta J, Olga M, Anna W, Stanislaw K, Marcin M Abstract Interruption of spinal cord (SC) continuity leads to functional loss below the lesion level. The purpose of this study was to evaluate the safety and efficacy of bone marrow nucleated cells (BMNCs) and multiple mesenchymal stem cells (MSCs) transplantations in spinal cord injury (SCI). A patient with total SC interruption at the Th2-3 level underwent experimental therapy with BMNCs and MSCs transplantations followed with intensive neurorehabilitation treatment. At admission, 6 hours after SCI, the patient was scored ASIA A, had a Th1 sensation level, paraplegia with sphincter palsy and was without the ability to control trunk movement. Neurophysiology examination showed bilateral axonal damage to the motor and sensory neural fibers with no motor unit potentials or peripheral motor nerve conduction in the lower extremities. The standard therapy had been applied and had not produce any positive results. The patient was treated with autologous BMNCs injected intravenously (3.2x10(9)) and intrathecally (0.5x10(9)) 10 weeks after the SCI and with five rounds of MSCs every 3-4 months (1.3-3.65x10(7)) administered via lumbar puncture. Total number of transplanted MSC cells during the course of treatment was 1.54x10(8). There were no complications related to transplantations, and no side effects related to the therapy during 2 years treatment. The ASIA score improved from A to C/D (from 112 to 231 points). The sensation level expanded from Th1 to L3-4, and the patients' ability to control the body trunk was fully restored. Bladder filling sensation, bladder control and anal sensation were also restored. Muscle strength in the left lower extremities improved from plegia to deep paresis (1 on the Lovett scale). The patient's ability to move lower extremities against gravity supported by the movements in quadriceps was restored. The patient gained the ability to stand in a standing frame and was able to walk with the support of hip and knee ortheses. Magnetic resonance imaging (MRI) revealed that at the Th2/Th3 level, where the hemorrhagic necrosis was initially observed, small tissue structures appeared. Our results suggest that repeated intrathecal infusions of mesechymal stem cells might have the potential to produce clinically meaningful improvements for SCI patients.
