A meniscus tear is normally repaired by the removal of the torn or damaged tissue via a partial meniscectomy. This can be effective in the short term but often it only gives temporary pain relief. In many cases the pain returns in time due to the loss of meniscal tissue and the cushioning function provided by a healthy meniscus. Over a longer period there is overwhelming evidence that degenerative changes occur, which, if left untreated, can lead to articular cartilage damage, the onset of osteoarthritis and eventually a total knee replacement.
In such cases helps the product Actifit®. Actifit® is implanted via arthroscopic surgery into the meniscal defect and as the damaged meniscal tissue heals Actifit® gradually dissolves and is removed naturally from the body.
Actifit® is a honeycomb scaffold that enables blood to flow through it and provide an anchor for new cellular in-growth as the body’s natural healing process takes place. Once the damaged section of the meniscus has been cut away and the meniscus resected to an area with good blood supply, the Actifit® implant is cut to size and stitched into place. Over time, the new cellular in-growth matures into new meniscus like tissue. This will help restore the cushioning function of the meniscus and delay the onset of osteoarthritis.
