Figure 3 - X-ray of a partial, or unicompartmental, knee replacement. This operation is done for patients whose arthritis is limited to one side of the knee. It may be done through a very small incision, and recovery from this procedure is usually much quicker than that seen with traditional total knee replacement.

Figure 5 - Knee arthritis can affect any of the three compartments of the knee. Medial-sided knee pain, located on the part of the knee that faces the opposite knee, is the most common location for arthritic pain.

Figure 8 - This patient had diffuse arthritis throughout his knee from an old fracture of the tibia (shinbone), which at that time was treated with the two screws that are visible. This patient was later treated with a total knee replacement, similar to the one shown in Figure 9.

Figure 10 - This patient's arthritis was confined to the medial ("inside") compartment of her knee on x-rays, and her pain was localized to that part of the knee as well. She was a good candidate for minimally-invasive partial knee replacement.

Figure 11 - Minimally-invasive partial knee replacement may be performed for either medial ("inside" of the knee) or lateral ("outside" of the knee) arthritis patterns, provided the symptoms are limited to that one part of the knee. X-rays of two knee replacements are shown here. On the left is a lateral replacement, and on the right is a medial replacement.

Figure 5 - This clinical photograph shows a typical incision used to insert a minimally-invasive partial knee replacement. The average length of the incision used in this procedure is 3 inches. Smaller incisions help permit faster recovery, and lead to less post-operative pain, compared to traditional knee replacement surgery.
