Further treatment depends on the extent of the accompanying damage to the articular cartilage and any injuries to the ligaments. If only the meniscus is injured, the individual will soon be able to play sport again. We recommend avoiding sudden twisting and stopping movements for three weeks. If there is also cartilage damage, the individual can expect discomfort and swelling for six to eight weeks. If only part of the meniscus is removed (as little as possible, as much as necessary), long-term outcomes are good. However, if the meniscus needs to be completely removed, osteoarthritis can be expected to develop after a period of 10 to 15 years.
Trials are therefore under way to create an artificial meniscus from bovine collagen. This involves using the regenerative capacity of the body to fill the implanted scaffold with the body’s own tissue, while the collagen that is used slowly dissolves. However, this method is still at the clinical-trial stage.
