Preserving Bone and Tissue

Through 20 years of research Dr. Gerard Engh developed a proprietary surgical procedure to enhance patient outcomes for a bone saving knee replacement including special surgical tools and techniques. The implants are designed as separate compartments for each aspect of a person's knee. With a small incision this bone saving surgery is called a "minimally invasive uni-compartmental knee arthroplasty" because it replaces only the diseased bone.
