Innovative Developments in Treating Knee Osteoarthritis

stickney-300Knee osteoarthritis is a progressive degenerative condition. Up until recently, all treatments have been directed at ameliorating its symptoms, with no hope of stopping disease progression. However, recent trials using Platelet-Rich Plasma (PRP) to treat the disease, rather than just the symptoms, have had encouraging results. 

PRP is concentrated plasma from your own blood that has been separated to include platelets, small blood cells that are loaded with growth factors responsible for healing cells and that help form clots so your body can repair any damage.  Many of these growth factors have been shown to promote cartilage regeneration. Although PRP has been used since 1987 to help with cell regeneration, using it to stimulate cartilage renewal is fairly new. The treatment entails drawing blood and injecting the PRP into the knee.  

Two recent scientific papers reported decreased pain and improved function after PRP injections. In 2011, the Journal of Arthroscopy reported on the comparative results of injecting knees with PRP versus viscosupplementation with Hyaluronic acid, a procedure that injects a lubricating fluid into the joint. At the six-month follow-up, the PRP group had less pain. A second study in the American Journal of Sports Medicine in 2016 reported on the comparative results of injecting PRP versus saline, which was used as a control. The results of this study showed dramatic improvement at six months in both pain and function for the PRP group. There is much more to learn about PRP injections, and a lot of research is ongoing in this field. 

This data is very encouraging. PRP is readily available, easily processed, safe, and one of the only proven regenerative treatments for early arthritis of the knee.

First nationwide prevalence study of hip and knee arthroplasty

The orthopedic community and public are well aware that hip and knee replacement operations are among the most commonly performed operations in the U.S. Figures show around 1 million of these procedures are performed each year. But how many people actually are living with a hip or knee replacement in the United States?

This important measure of the impact of joint arthroplasty on public health, known as prevalence, has been missing until the recent release of the Mayo Clinic orthopedics study.

Treatments that reduce knee buckling may help prevent falls in older adults

Symptoms of knee instability in older adults may indicate an increased risk of falling and of experiencing the various physical and psychological effects that can result from falling, according to a study published in Arthritis Care & Research, a journal of the American College of Rheumatology (ACR). The findings indicate that determining effective treatments for knee instability should be an important priority as clinicians care for aging patients.

Knee buckling, often described as a knee “giving way,” is a symptom of knee instability that frequently affects older individuals, in particular those with knee pain and knee osteoarthritis (OA), and may be caused by muscle weakness and balance difficulties. If knee instability leads to frequent falls and fall-related injuries, exercises and other interventions that stabilize the knee may help maintain older individuals’ health and quality of life.

Knee Replacements : Success Is Process Driven

Successful knee replacements can radically improve your quality of life. On the other hand, if your knee replacement does not go well, it will be a source of never ending frustration and disability. While many people do well, and some do exceptionally well, there are still a fair number of you out there who continue to have problems.

What can be done to maximize your chances of success following a knee replacement?

A successful, well functioning knee replacement will be the result of a reproducible process that should be relatively surgeon agnostic, as well as prosthetic agnostic. That means that there are many surgeons capable of getting you back on your feet. Many are right in your backyard. You shouldn’t succumb to the hype or feel the need to travel to Chicago and pay $60,000 for an ambulatory knee replacement.

Minimally Invasive Total Knee Replacement

Minimally Invasive (MIS) knee replacement is a new technique which can
significantly improve a patient’s rate of recovery from surgery. Dr. Stephen Kelly has been a leader in this field for OA Centers for Orthopaedics. He has successfully performed this procedure more than 500 times with significant improvements in patient’s pain after surgery and very rapid return to function.

Knee replacement surgery traditionally has required a 10-12 inch incision with the cutting of muscle and tendon. This new minimally invasive technique involves …

Graft Properties Affect Knee Ligament Surgery Outcome More Than Surgical Technique

 

In anterior cruciate ligament (ACL) reconstruction, graft stiffness and pre-strain play a more vital role than the choice of surgical technique, indicates a new study from the University of Eastern Finland. The study developed a computational 3D model of the knee joint, which can be used in the prevention of osteoarthritis (OA), specifically OA resulting from trauma.

OA is a major burden to society. It is estimated that over 100 million people suffer from …
