Each meniscus has an outer vascular zone (red-red zone), which has a good blood supply and healing potential as well as a central avascular zone (white-white zone), which has limited healing capability. [2] The medial meniscus is more prone to injury due to its firm attachment to the joint capsule and limited mobility.
The operation room costs and hospital charges for that amount of extra time came to about $1,580 more expensive. [42] This also applies to having a torn meniscus during the procedure. Fixing the torn cartilage will increase the procedure time, increasing cost.
In 2008 the U.S. Department of Health and Human Services reported a combined total of 2,295 discharges for the principal diagnosis of tear of lateral cartilage/meniscus (836.0), tear of medial cartilage/meniscus (836.1), and tear of cartilage/meniscus (836.2). Females had a total of 53.49% discharges, while males had 45.72%.
Arthroscopic surgery, however, does not appear to result in benefits to adults when performed for knee pain in patients with osteoarthritis who have a meniscal tear. [18] [12] [19] This may be due to the fact that a torn meniscus may often not cause pain and symptoms, which may be caused by the osteoarthritis alone. [20]
Injuries to the ACL are common, 250,000 ACL injuries occur on an annual basis. This corresponds to a 1 in 3,000 chance of an individual sustaining an ACL injury. Ligaments in the ACL or meniscus are usually torn with an external force being applied to the knee joint. The ACL can be torn without an external force being applied [11]
Note that the numbers above do not correspond to a percentile, but are notionally a percentage of the maximum raw marks available. Various tertiary institutions in Australia have policies on the allocations for each grade and scaling may occur to meet these policies. These policies may vary also according to the degree year (higher percentages ...
The surgery was called "controversial" by many sportswriters, due to a lack of studies on the long-term effects and the fact that an unsuccessful surgery could end an athlete's career. [9] Steadman has also adapted the surgery into a treatment to help reattach torn ligaments (a technique he calls the "healing response"). [citation needed]
A meniscus transplant or meniscal transplant is a transplant of the meniscus of the knee, which separates the thigh bone from the lower leg bone . The worn or damaged meniscus is removed and is replaced with a new one from a donor. The meniscus to be transplanted is taken from a cadaver, and, as such, is known as an allograft.
