[5] [6] [14] The historic quantified definition of grades I, II, and III represented 0–5 mm, 5–10 mm, and >10 mm of medial compartment gapping, respectively. [15] LaPrade et al. reported, however, that a simulated grade III sMCL injury showed only 3.2 mm of increased medial compartment gapping compared to the intact state. [15]
The knee joint contains two crescent-shaped fibrocartilaginous structures, the menisci (medial and lateral), which serve as shock absorbers and stabilize the joint during movement. 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 ...
[7] [unreliable source?] More chronic injury occurs with osteoarthritis, made worse by obesity and high-impact activity. The medial meniscus and the medial compartment are more commonly affected than the lateral compartment. Often, moderate to severe injury or injury past early middle age to the meniscus will indicate a total knee replacement.
The components of each of these compartments can experience repetitive strain, injury or disease. [1] Running long distance can cause pain to the knee joint, as it is a high-impact exercise. [2] The location and severity of knee pain may vary, depending on the cause of the problem. Signs and symptoms that sometimes accompany knee pain include: [1]
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.
Injury. The tear of meniscus is among the most common knee injuries. It is usually caused by torsional stress; twisting or turning of the knee too quickly with the foot planted on the ground while the knee is flexed. The feeling of a "pop" in the knee is usually felt when the meniscus is torn.
Depending on the grade of the injury, the lowest grade (grade 1) can take between 2 and 10 weeks for the injury to fully heal. Recovery times for grades 2 and 3 can take several weeks to several months. Treatment of a partial tear or stretch injury is usually conservative. Most injuries that are partial and isolated can be treated without ...
A forceful medial blow to the knee can cause collateral ligament injury. A reduction in range of motion and pain are symptoms of collateral ligament injury. Meniscus injuries: acute or repeated injury to the meniscus – the shock absorber of the knee – causes meniscus injuries. A person with meniscus injuries experiences difficulty squatting ...
