A tear of a meniscus is a rupturing of one or more of the fibrocartilage strips in the knee called menisci. When doctors and patients refer to "torn cartilage" in the knee, they actually may be referring to an injury to a meniscus at the top of one of the tibiae. Menisci can be torn during innocuous activities such as walking or squatting.
Meniscal repair: Preferred for young patients or those with tears in the vascular (red-red) zone, which has healing potential. Arthroscopic sutures are used to repair the torn meniscus. Partial meniscectomy : [ 7 ] If the tear is in a non-repairable location (white-white zone) or the meniscal tissue is extensively damaged, the displaced ...
grade 1: the cartilage has a soft spot, blisters, or superficial wear; grade 2: minor tears of less than one-half the thickness of the cartilage layer; grade 3: lesions have deep crevices of more than one-half the thickness of the cartilage layer; grade 4: the cartilage tear is full thickness and exposes the underlying (subchondral) bone
The effect of low doses of radiation on carcinogenesis also are disputed. [62] Although MRI is associated with biological effects, these have not been proven to cause measurable harm. [29] Iodinated contrast medium is routinely used in CT and the main adverse events are anaphylactoid reactions and nephrotoxicity. [63]
Side-to-side movements of the knee should be avoided. The patient is allowed to bear weight as tolerated and should perform quadriceps strengthening exercises along with range of motion exercises. The typical return-to-play time frame for most athletes with a grade III medial knee injury undergoing a rehabilitation program is 5 to 7 weeks.
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. Large tears to the meniscus may require surgical repair or removal. In terms of a meniscus tear, the doctor can categorize the injury ...
Bilateral varus stress AP radiographs comparing the injured leg to the normal side are useful in assessing the lateral joint space for opening after a potential injury. [2] [13] More than a 2.7 mm increase between sides indicates a fibular collateral ligament tear, while greater than 4.0 mm indicates with a grade III posterolateral knee injury ...
Medial meniscus intact (green). MRI, coronal T2 *-weighted GRE sequence. The MRI image in the article. Is it the left knee or the right? Comes.amanuensis 12:20, 10 August 2013 (UTC) Looks like a left knee, normally the structures on the left side (such as the iliotibial tract visible here) are seen on the right in the picture. However it could ...
