Waking up stem cells already in your knees and getting them to fix the wear and tear damage causing your pain may shed light on the importance of stem cell numbers in stem cell therapy. In this article I will explore whether numbers of stem cells or the ability to communicate a healing message among existing stem cells will provide a “good heal” to damaged joints.
In 2011, doctors at the University of Aberdeen published research in the journal Arthritis and rheumatism that provided the first evidence that resident stem cells in the knee joint synovium underwent proliferation and chondrogenic differentiation following injury. In other words the number of stem cells in an injured knee increased and began to turn themselves into cartilage.(1) This paper, presenting the idea that stem cells in an injured knee increased in numbers in preparation of healing has been cited by more than 40 medical studies.
Biological knee reconstruction is a new and popular term to describe the surgical procedure of combined meniscal allograft transplantation and surgical cartilage repair. It is recommended to patients with painful, meniscus-deficient knees and full-thickness cartilage damage.
In 2014 the idea that cell-based therapies, such as bone marrow derived stem cell injections, began to catch on in the athletic world as an alternative to surgical procedures. In the Orthopaedic journal of sports medicine doctors wrote:
Hyaluronic acid is a naturally occurring substance that is a major component of the protective synovial fluid that surrounds the knee.
In its natural form it is also a key component of wound healing. In its processed form used for injection purposes, hyaluronic acid is NOT a key healing component as attested to by suggestions and recommendations that these injections are stop gaps until knee replacement can be performed.
Some debate whether to get hyaluronic acid injections or stem cells. Research suggests stem cells may provide the answer to get both. (more…)
New research into the healing world of the knee meniscus is fascinating. Despite decades of traditional medical beliefs that because of its poor or even absent network of blood vessels and blood supply, parts of the knee meniscus cannot heal, researchers are discovering the meniscus is in fact, always trying to heal itself.
A recent study from doctors in Australia outlined the frustrations and challenges an overweight or obese person suffers with their knee pain.
- Most obese and overweight patients are not satisfied with their body weight, want to lose weight and want to participate in a diet program.
- They feel weight loss and better health would help with their knee pain.
- Despite this: They were more likely to report continuing weight gain.
- While many overweight patients rated food intake to be a main determinant of their weight problems , the more obese participants more frequently believed genetic and metabolic factors to be important.
- When asked to chose one program diet or exercise – that they thought would help them with their weight loss goals – it was almost an even split – 53% thought physical activity – 47% thought diet.(1)
