Spheroids of human autologous matrix-associated chondrocytes, sold under the brand name Spherox, is a medication used to repair defects to the cartilage in the knee in adults who are experiencing knee pain and problems moving the knee. [1] It is used where the affected area is no larger than 10 cm 2 (1.6 sq in). [1]
Because mesenchymal stem cells may regenerate cartilage, cartilage growth in human knees using autologous cultured mesenchymal stem cells is under research and preliminary clinical use, and appears to be safe as of 2016. [11] An advantage to this approach is that a person's own stem cells are used, avoiding tissue rejection by the immune system ...
Marrow-nucleated cells are used every day in regenerative orthopedics. The knee microfracture surgery technique relies on the release of these cells into a cartilage lesion to initiate fibrocartilage repair in osteochondral defects. [13] In addition, this cell population has also been shown to assist in the repair of non-union fractures. [14]
A 2017 review described the evidence as moderate for knee osteoarthritis. [15] A 2016 review found benefit but there was a moderate degree of variability between trials and risk of bias. [16] In 2019, the American College of Rheumatology recommended against prolotherapy for knee osteoarthritis. [17]
Mesenchymal stem cells (MSCs), also known as mesenchymal stromal cells or medicinal signaling cells, are multipotent stromal cells that can differentiate into a variety of cell types, including osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells which give rise to marrow adipose tissue).
In osteoarthritis, joint injection of glucocorticoids (such as hydrocortisone) leads to short term pain relief that may last between a few weeks and a few months. [5] Injections of hyaluronic acid have not produced improvement compared to placebo for knee arthritis, [6] [7] but did increase risk of further pain. [6]
After an image of Karl-Anthony Towns wearing a knee brace surfaced over the weekend, ESPN's Ramona Shelburne reported on Sunday that he underwent treatment in both knees and other parts of his body.
They are given by injection. [2] Common side effects may include joint pain, rash, vomiting, and headache. [4] Serious side effects may include heart attacks, stroke, increased cancer growth, or pure red cell aplasia. [2] It is unclear if use is safe during pregnancy. [5] [6] They work similar to naturally occurring erythropoietin. [1]
