Revolutionizing Knee Repair

Mirror – A true representation of your natural knee.

Partial Knee

The MIRROR™ Partial Knee System is a revolutionary solution designed to balance a patient’s soft tissue during unicompartmental knee arthroplasty. The Mirror instrument set allows the surgeon to prepare the femoral condyle using the patients' own unique, natural knee motion to balance soft tissue. This results in a kinematically-correct, patient-specific resurfacing of only the areas affected by arthritis.

Why Choose a Partial Knee Replacement Over a Total Knee Replacement

Total knee replacement, also known as total knee arthroplasty, is a highly successful surgical procedure. It is not the only surgical treatment option for knee osteoarthritis, though. Some patients are candidates for partial knee replacement, also known as unicompartmental knee replacement.

For patients with only one diseased knee compartment, a partial knee replacement can be an excellent option especially for those interested in maintaining an active lifestyle with a high degree of mobility and balance. Partial knee replacement procedures offer faster recovery times, greater range of motion, less bone and tissue resection, and fewer complications.

The knee has three compartments:  the medial (inside) compartment, the lateral compartment (outside of the knee) and the patellofemoral compartment (in front of the knee). In most knee osteoarthritis patients, only one compartment of the knee is affected and it is usually the medial compartment. The lateral compartment can be affected, but it is less common.

A partial knee replacement involves replacing only the affected compartment of the knee and keeps more of the patients own body structure remains intact. On the other hand, a total knee replacement involves replacement of all three compartments of the knee and removes all of the ligaments.   For a partial knee replacement procedure, the anterior and posterior cruciate ligaments are preserved and minimal bone is removed during the procedure, leaving available the option of a total knee replacement at a later date.
