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 ...
The meniscus is a C-shaped piece of fibrocartilage located at the peripheral aspect of the knee joint that offers lubrication and nutrition to the joint. Each knee has two menisci, medial and lateral, whose purpose is to provide space between the tibia and the femur, preventing friction and allowing for the diffusion of articular cartilage.
Each knee has an inside (medial) and an outside (lateral) meniscus.The menisci play several key roles that are vital in maintaining the health of the knee. [2] Specifically, they act as shock absorbers and load sharers, increase the stability of the knee, and provide lubrication and nutrition to the bearing surface (articular cartilage) of the knee.
One meniscus rests on the medial tibial plateau; this is the medial meniscus. The other meniscus rests on the lateral tibial plateau; this is the lateral meniscus. [3] [4] The menisci are nourished by small blood vessels but have a large area in the center with no direct blood supply (avascular).
Portland Trail Blazers rookie Greg Oden underwent the procedure on his right knee in early September 2007 and missed the entire 2007–2008 NBA season. At only 19 at the time of the surgery, doctors were confident that he would return to at or near his full strength by the 2008–2009 season; he had a second microfracture surgery, this time on ...
The lateral meniscus is also known as the external semilunar fibrocartilage. It is a fibrocartilage band on the lateral side of the knee joint and can easily be injured with torsional stress or direct force. Each knee has a medial and lateral meniscus, consisting of connective tissue and collagen fibers. Menisci are needed to distribute the ...
In March 2023, Ball had a cartilage transplant procedure on the knee after a torn meniscus in January 2022. That surgery, in which damaged cartilage is repaired with cartilage cells from the ...
Knee arthroscopy, or arthroscopic knee surgery, is a surgery that uses arthroscopic techniques. It has, in many cases, replaced the classic open surgery that was performed in the past. Arthroscopic knee surgery is one of the most common orthopaedic procedures, performed approximately 2 million times worldwide each year. [2]
