A picture of an operation theatre before a knee replacement surgery. The picture shows a monitor used in a minimally invasive knee replacement surgery, local anesthesia instruments and other instruments used in the operation.

Cutting of the knee joint in the initial stage of the knee replacement surgery: This is a traditional type of knee replacement surgery in which incisions of larger sizes are done. This type of surgery results into relatively more blood loss and a longer recovery period. The surgeon in this picture has performed the cut so as to replace the knee joint with an artificial implant made up of metal and plastic.

Beginning of the knee replacement surgery: The surgeon in this picture is inspecting the diseased joint. Early inspection with the help various tests allows the surgeon to detect the defected joint and then efficiently replace it.

A knee replacement surgery and the instruments used in it. The defected part of the knee joint is first detached and then replaced with an artificial implant made up of metal and plastic. This is a critical stage of the surgery.

Artificial implant being placed during a knee replacement surgery. Femur, Tibia and Patella are three different bones which are operated upon. Patella which slides on the Femur is the defected bone which is replaced with the artificial implant.

Final stage of knee replacement surgery before stitching the wound. The picture of knee replacement surgery shows the artificial implant made up of metal and plastic. The implant makes it possible for the lower end of the thigh bone (Femur), upper end of the shin bone (Tibia) and the knee cap (Patella) to move smoothly without any complications.

A view of the knee replacement surgery. The implant fixed in the knee shows the knee femoral component which is attached to the femur bone, a polyethylene articulating surface and the stemmed tibial plate attached to the tibia bone. In most of the cases it has been observed that the implant lasts for more than fifteen years.

Structure of the bone before knee replacement surgery. Knee joint consists of a thigh bone and a shin bone forming a knee joint with a knee cap. The joint is held by strong protective tissue which is called cartilage.

Structure of the bone after the knee replacement surgery. The replaced artificial implant consists of a metal femoral component fixed with Femur, an articulating polyethylene surface and a plate fixed with Tibia.

Picture describing different parts of the implant used in a knee replacement surgery. The metal femoral component is a moulded structure which makes it easier to attach with femur bone. The tibial component is structured so as to easily fix with tibia bone. The plastic spacer helps the joint to move and provide strength.

The incision involved in a knee replacement surgery. This is a traditional type of knee replacement surgery which involves a longer incision a relatively bigger scar.

X- Ray showing a right leg with degenerated medial. The knee joint has lost its efficiency because of the failure of femur, knee cap and tibia to function properly.

Normal knee anatomy. The picture shows a Thigh bone connected with a Shin bone through a Meniscus. Cartilage is the protective tissue which holds the knee joint and provides the strength. This is the anatomy of a healthy knee joint.

Knee with arthritis. The picture shows a degenerated knee joint which has developed knee arthritis. Worn cartilage and torn meniscus results into inefficient functioning of the femur and tibia.

Some pictures showing exercises during knee replacement rehabilitation

Straight leg raises. This exercise is performed in the initial stage of the recovery period so as to enhance the muscular strength.

Ankle pumps. This is a light exercise advised in the initial stage of the recovery period.

Knee straightening exercises. This exercise helps avoid blood clots and stiffness. It also helps improve muscular strength.

Bed supported knee bends. Knee bends is a lighter exercise performed in the initial stages of the rehabilitation period. This exercise is very effective in avoiding blood clots.

Assisted knee bends. This exercise is primarily to improve leg strength.

A healthy knee joint surface. A knee joint consists of three bones. Femur, Tibia and Patella are these three bones. Cartilage is the protective tissue covering all these three bones so as to provide strength to the knee joint.

An arthritic knee joint surface. Knee Arthritis damages the cartilage and the bone surface which impedes the smooth functioning of the joint. The damaged cartilage results into pain which could be treated with the help of knee replacement surgery.
