An 81 year old male presented with finger point pain on the medial (inside) part of his knee. He was debilitated by the pain and was seeking options for treatment. After asking the patient a number of questions, examining the patient, and reviewing his x-rays I decided to do a partial knee replacement. 3 months post-surgery he had no pain, had 140° of movement, and was enjoying playing golf again.
Front view - The x-ray on the above left shows osteoarthritis (OA) of the medial (inside) compartment of the knee (red circle). The x-ray on the right shows the partial knee replacement. As you can see only one part (the medial part) has been replaced.
Side view - These x-rays are from the same patient taken from the side of the knee. The x-ray on the left shows the knee before the operation and the x-ray on the right shows the partial knee replacement.
