Partial knee replacement is an innovative treatment option for those living with mid-stage knee osteoarthritis (OA) that has not yet progressed to all three compartments of the knee.
Knee pain with activity in only one part of your knee, usually on the inner knee and/or under the knee cap.
X-rays that show arthritis in only one compartment of your knee.
Start-up knee pain or stiffness when activities are initiated from a sitting position.
Failed to respond to non-surgical treatments such non-steroidal anti-inflammatory medication, therapy and injections.
In a partial knee replacement, only the arthritic portion of the knee is resurfaced. This preserves healthy bone and tissue, giving you more options for the future and a more rapid recovery. Recent advancements in orthopedics now allow for a much higher level of precision, smaller incisions, and much faster recovery. Customized implants replace parts of your knee by mirroring the surface contours of your knee to help provide greater coverage and implant fit.
The procedure is performed through a four to six inch incision over the knee. Tactile, intelligent robotic arm technology and 3-D visualization of the knee guides the surgeon in controlled resurfacing of the pre-defined knee disease, saving as much of the patient’s healthy bone and surrounding tissue as possible. Computer modeling of the patient’s pre-surgical plan using CT scan data and, during the procedure, real-time visual, tactile, and auditory feedback facilitates ideal implant positioning and placement. It is this level of planning and surgical accuracy in treating earlier stage knee osteoarthritis that can result in a more natural feeling knee and motion.
In many cases, patients are permitted to walk soon after surgery, drive a car within two weeks and return to normal daily activities shortly thereafter.
Knee problems might or might not be treated with knee replacement right away. Doctors often suggest trying other treatments first. These can include weight loss, medicines, knee braces, injections, or physical therapy. If these treatments do not help enough, doctors then suggest knee replacement.
A partial knee replacement is a medical term for knee surgery replacing the cartilage of only one compartment of the knee. This could consist of one of the three compartments, the medial (inside), lateral (outside), or patellofemoral (front or knee cap). When two or three of these compartments of the knee have severe arthritis a total knee replacement is likely more appropriate versus a partial knee replacement. If you’re experiencing knee pain, ask your surgeon if you’re a good candidate for surgery.
