Partial knee replacement - series

Normal anatomy

Cartilage covers the end of bones in joints to provide shock absorption during movement.

Normal anatomy

Indication

Normal cartilage on the end of the femur is compared to worn, damaged femoral cartilage.

Indication

Incision

A small cut (incision), typically about three inches, is made over the area of the knee that is damaged.

Incision

Procedure

The damaged bone is removed and replaced with an implant (prosthetic) made of plastic and metal.

Procedure

Aftercare

Most patients have a rapid recovery and have considerably less pain than they did before surgery and go home the day after surgery (unlike the 3 or 4 days required by a total knee replacement).
