About Cayenne MIRROR™

About us

Cayenne Mirror™ Partial Knee System is a highly differentiated product for treating early onset of knee arthritis. It was developed by Dr. Jerry Engh, a world-renowned orthopaedic surgeon and industry pioneer in the area of partial and total knee research and development. About us After graduating from Davidson College, he attended medical school at the University of Virginia. Following an internship and residency at Yale-New Haven Hospital, Dr. Engh spent two years as a major in the Army Medical Corps. He then went to work at The Anderson Orthopaedic Clinic, which had been founded by his father, O. Anderson Engh. Dr. Engh was the past president of the Knee Society and had to purchase his own first arthoscope as it was considered too “experimental” at that time.

Hundreds of thousands of people suffering from the debilitating pain of arthritis undergo knee replacement each year. Patient satisfaction and implant performance are directly related to how accurately the implants are positioned to function naturally with the ligaments within the knee, which is to balance the knee. For the surgeon, balancing the knee is the most challenging aspect of the procedure. It was this limitation that led Dr. Engh to rethink the surgical approach from the perspective of re-establishing natural knee balance in combination with preparing the implant surfaces, which only the Mirror system does.

The difference between the Mirror™ Partial Knee System and all other alternatives is in our philosophy to achieve optimal outcomes using cost effective surgical methods. The Mirror™ Partial Knee System steps up where others fall short by providing surgeons a friendly and efficient approach to replacing only the areas of the bone damaged by arthritis, returning knees to their natural range of motion. To offer the procedure, hospitals and surgery centers are not required to acquire expensive equipment or incur additional costs tied to approaches that rely on software from CT or MRI imaging studies to create cutting guides for surgeons.
