The knee joint, which appears like a simple hinge-joint, is one of the most complex joints in the body.
The knee joint is made up of the femur (thigh bone), tibia (lower leg bone) and patella (the kneecap). All these bones are lined with articular cartilage (surface cartilage). This articular cartilage acts like a shock absorber and allows a smooth, low friction surface for the knee to move on. Between the tibia and femur lie two floating cartilages called menisci. The medial (inner) meniscus and the lateral (outer) meniscus rest on the tibial surface cartilage and are mobile. The menisci also act as shock absorbers and stabilizers. The knee is stabilized by ligaments that are both inside and outside the joint. The medial and lateral collateral ligaments support the knee from excessive side to side movement. The (internal) anterior and posterior cruciate ligaments support the knee from buckling and giving way. The knee joint is surrounded by a capsule (envelope) that produces a small amount of synovial (lubricating) fluid to help with smooth motion. Thigh muscles are important secondary knee stabilizers.
We tend to ignore our knees until something happens to them that causes pain. If we take good care of our knees now, before there is a problem, we can really help ourselves. In addition, if some problems with the knees develop, an exercise program can be extremely beneficial. To understand the functions, conditions, surgeries & procedures of the knee better, we have included an interactive animated presentation.Knee anatomy

Arthritis of the Knee joint
The term arthritis literally means inflammation of a joint, but is generally used to describe any condition in which there is damage to the cartilage.

Total Knee Replacement (TKR).
A total knee replacement (TKR) or total knee arthroplasty is a surgery that resurfaces an arthritic knee joint with an artificial metal or plastic replacement parts called the ‘prostheses’

Revision knee replacement.
This means that part or all of your previous knee replacement needs to be revised. This operation varies from very minor adjustments to massive operations replacing significant amounts of bone and hence is difficult to describe in full.
