A knee X-ray and/or blood test – this can assist to exclude certain types of arthritis or inflammation. Magnetic Resonance Imaging – to observe cartilage condition and assess deterioration; Arthroscopy – a low invasive approach to image the inside of the knee joint by inserting an endoscope into the knee joint.

Though articular cartilage damage is not life-threatening, it does strongly affect one's quality of life. Articular cartilage damage is often the cause of severe pain, knee swelling, substantial reduction in mobility and severe restrictions to one's activities. Over the last decades, however, research has focused on regenerating damaged joints.
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.
Generally, the term "meniscus" is used to refer to the cartilage of the knee, either to the lateral or medial meniscus. Both are cartilaginous tissues that provide structural integrity to the knee when it undergoes tension and torsion. The menisci are also known as "semi-lunar" cartilages, referring to their half-moon, crescent shape.
In the adult the articular surface is about 12 cm 2 (1.9 sq in) and covered by cartilage, which can reach a maximal thickness of 6 mm (0.24 in) in the centre at about 30 years of age. Owing to the great stress on the patellofemoral joint during resisted knee flexion, the articular cartilage of the patella is among the thickest in the human body.
ACI articular cartilage repair procedures take place in three stages. First, cartilage cells are extracted arthroscopically from the patient's healthy articular cartilage that is located in a non load-bearing area of either the intercondylar notch or the superior ridge of the femoral condyles.
Removal of the meniscus cartilage leads to progressive, degenerative arthritis of the knee joint. Replacing the badly damaged or deficient meniscus with a meniscus transplant from a human donor restores normal knee structure and helps protect the remaining joint surfaces. Meniscal transplantation is relatively uncommon, although it is gaining ...
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 ...
