In the simplest terms possible, meniscus repair is a minimally-invasive surgical procedure that basically stitches together the portions of the tear much like you would do to repair an article of clothing. Relatively speaking, meniscal repair, or preservation, is a newer treatment option than the original treatment method of a meniscectomy during which a surgeon removes all or part of the damaged meniscus.
The increase in popularity among both patient and surgeons for meniscal repair comes at the same time as the long-term consequences of removing the meniscus, specifically its potential role in the development of osteoarthritis, are becoming more apparent1. In addition, recent technological advances have made repairs of the meniscus potentially easier, faster and stronger than ever before.
A primary concern for most patients following any type of knee surgery is the development of osteoarthritis and the potential need for future surgeries.2 Meniscus repair is popular with patients because it helps reduce these risks.2
Not all meniscus tears are suitable for repair. Your surgeon will recommend the best treatment option for your situation based on the type of meniscus tear, its size, location, and consideration for your age and activity levels.
Unlike meniscus repair, a meniscectomy is a type of surgery where at least some portion of the damaged meniscus is removed. Whether to remove all or part of your meniscus is typically based on issues like the location, length, pattern, and stability of the tear, as well as the overall condition of the rest of your meniscus. Your surgeon may also take into consideration the condition of the rest of your knee, your age, and any age- or injury-related degeneration that has already occurred.
As you might expect, whenever any portion of your meniscus is removed, there is the possibility for a reduction in the cushioning and shock absorbing benefits the meniscus provides. Depending on the amount of meniscus that is removed, the initial impact of this loss may not pose much of an issue. However, over time, friction caused by the repeated motion of the knee can cause the remaining cartilage around the damage to wear away and lead to a condition known as osteoarthritis.
Because of the potentially negative impact a total meniscectomy can have on a patient’s ability to be active, surgeons generally try to remove as little of the meniscus as possible. However, under some clinical conditions a surgeon may only be able to perform a meniscectomy.
Fact: Sure, every patient hopes for a speedy and painless recovery – but that’s not the only thing to be considered. You may be sacrificing long-term joint health for short-term convenience. It’s always smart to weigh the consequences and compare your options.
Tear is stitched together and natural meniscus shape maintained.
Preserves tissue and may return normal knee joint pressure3.
Along with rehabilitation, repair can facilitate the return to near normal activity levels.
Meniscus tissue is removed in part or whole.
Potential of accelerated advanced arthritis4 and higher risk for knee replacement in less than 9 years5,6
May lead to diminished long-term sports performance, mobility, and total knee health7
In a 2010 study, 81% of patients having a meniscus repair did not show any significant osteoarthritis at the time of follow up, while 60% of meniscectomy patients did show osteoarthritic changes. Functional scores showed no difference between the two procedures, however 94% of meniscal repair patients returned to their previous level of sport activity compared to only 44% of the meniscectomy group. There was a significant drop in sport activity in the meniscectomy group only.8
Following meniscus repair surgery, patients typically wear a brace for 4-6 weeks, and may need the support of crutches. Heavy lifting may be restricted during this time. Regular rehabilitation exercises are commonly prescribed to restore knee mobility and strength. Generally, patients return to near normal active lifestyles after surgery and rehabilitation.9
Individual results may vary. There are risks associated with any surgical procedure including meniscus repair. Meniscus repair is not recommended for everyone. Consult your physician to determine if this procedure is right for you.
