Introduction Osteoarthritis of the knee carries a lifetime risk of roughly 45 percent and increases to 60 percent amongst obese individuals.
Osteoarthritis of the knee carries a lifetime risk of roughly 45 percent and increases to 60 percent amongst obese individuals. Degradative enzymes are overexpressed in the knee and prevalence increases with each decade of life. Progression according to imaging can be graded as localized (focal) or diffuse, meaning it affects more than 75 percent of the region.
It can also be graded as normal, doubtful, mild, moderate or severe (grade 0โ4 on the Kellegren Lawrence scale). Case presentation While in your clinic, you are seeing a 56 year old football coach with knee pain. He states he knows he has arthritis in his knee, but would like to know how severe this is.
He has definitive osteophytes and possibly some mild joint space narrowing. This description correlates best with which grade of the Kellgren and Lawrence System? Grade 3 Many patients will likely present to a sports medicine practice and ask if there are any ways to reverse or prevent further damage when diagnosed with knee osteoarthritis.
No conventional or pharmacological therapies have demonstrated unequivocal efficacy in halting disease progression and injections of molecular compounds to assist healing, such as corticosteroids, may only have pain reducing effects. Regenerative therapies have gained traction over the past ten to fifteen years, as osteoarthritis is a degenerative process. This is especially the case in the challenging subset of younger OA patients, who have high functional demands yet limited indications for invasive surgical treatments.
Other interested patients may be middle-aged and expect to maintain a high activity level or want to postpone surgical intervention. It is proposed that endogenous mesenchymal stem cell (MSCs) are depleted in the disease process of osteoarthritis and stem cell therapies may have potential for repair or regeneration of cartilage. Mesenchymal cells are able to differentiate into several cell types such as osteoblasts, chondrocytes, or adipocytes and have high plasticity, limited self-renewal capabilities, and immune-suppressive and anti-inflammatory actions.
If you are experiencing symptoms that may be related to stem cell treatment for knee osteoarthritis, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
