The population for whom meniscal transplantation is appropriate has expanded. Survival data from a recent, long-term follow-up study shows that meniscal transplantation is also successful in older, arthritic patients with a success rate of 89.4% (42 of 47 transplants) at an average of 4.4 years.
[citation needed] There is little medical follow-up after meniscectomy and official medical documentation tends to ignore the imperfections and side-effects of this procedure. If the meniscus was repaired, the rehabilitation program that follows is a lot more intensive. After the surgery, a hinged knee brace is sometimes placed on the patient.
The procedure is less effective in treating older patients, overweight patients, or a cartilage lesion larger than 2.5 cm. [11] Further on, chances are high that after only 1 or 2 years of the surgery symptoms start to return as the fibrocartilage wears away, forcing the patient to reengage in articular cartilage repair.
Healing of the medial meniscus is generally not possible unless the patient is very young, usually <15 years old. Damage to the outer third of the meniscus has the best healing potential because of the blood supply, but the inner two thirds of the medial meniscus has a limited blood supply and thus limited healing ability.
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.
The body's inflammatory response to surgery likely plays an important role, at least in elderly patients. Various research initiatives during recent years have evaluated whether actions taken before, during and after surgery can lessen the possible deleterious effects of inflammation. For example, anti-inflammatory agents can be given before ...
These side effects arise in approximately 10–20% of users, are mild to moderate in severity, and can be managed by slowly adjusting medication doses. [192] Less common secondary effects include muscle cramps , decreased heart rate ( bradycardia ), decreased appetite and weight, and increased gastric acid production.
Lateral meniscal tears are more common in acute ACL injuries, whereas medial meniscal injuries are more common in chronic ACL-deficient knees and more amenable to repair. [ 9 ] Meta-analysis shows that in acute injuries of the ACL associated with a meniscus tear, 44% were of the medial meniscus, whereas 56% were of the lateral meniscus; in ...
