Partial Knee Replacement Surgery
Evolution of Partial Knee Replacement Surgery
Partial knee replacement surgery is the process of surgically removing a few millimiters of damaged cartilarge and bone from the affected compartment and replacing or resurfacing the that single area with metal and plastic. It can be performed for any of the above mentioned three compartments, although is is most commonly performed to replace the medial or inside region of the knee. The advantages of this procedure are that more of the native knee are retained by the patient which is thought to lead to faster recovery and more anatomic or normal motion within the knee joint.
In order to benefit from partial knee replacement, patient’s must meet certain indications prior to surgery which include pain in only one region of the knee, x-rays demonstrating loss of cartilage in only one are, a stable knee without evidence of ligamentous injury, good range of motion, and a body mass index within an acceptable range. The surgery is performed by making a small incision and the front of the knee and with the use of cutting guides, resecting the regions of damaged bone and cartilage and replacing them with metal and plastic components. Following surgery patients are typically permitted to walk on their new knee the same day and are discharged from the hospital within 24, and more often this operation is performed on an outpatient setting, same day surgery.
