A meniscal repair has a higher success rate given an adequate blood supply to the peripheral rim. [36] [failed verification] The interior of the meniscus is avascular, but the blood supply can penetrate up to about 6 millimetres (0.24 in). Therefore, meniscus tears that occur near the peripheral rim are able to heal after a meniscal repair. [1]
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.
A bucket-handle tear of the knee is a specific type of meniscal injury characterized by a longitudinal tear of the medial or lateral meniscus, where a displaced inner fragment resembles the appearance of a "bucket handle". [1] This displaced meniscal fragment often remains attached at the anterior and posterior horns but dislocates into the ...
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.
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.
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.
New RSV vaccines are now available to help prevent serious infection in people over 60. Doctors explain the RSV vaccine and its side effects in older adults.
The procedures are more commonly performed to treat meniscus injury and to perform anterior cruciate ligament reconstruction. [3] While knee arthroscopy is commonly used for partial meniscectomy (trimming a torn meniscus) on middle aged to older adults with knee pain, the claimed positive results seem to lack scientific evidence.
