Partial Knee Replacements Provide Quicker Recovery for Those Eligible

While partial knee replacements are common in Europe, patellofemoral replacements remain largely unused in the United States, despite many benefits for patients. Ronald Grelsamer, MD, Associate Professor of Orthopedic Surgery at The Mount Sinai Medical Center, is one of the few doctors in the tri-state area with a sustained interest in patellofemoral replacements. The technique allows for less surgical dissection, a shorter hospital stay, as well as a shorter period of rehab and superior motion when compared to total knee replacement surgery. However, patellofemoral surgery is reserved for patients whose arthritis is confined to the patellofemoral compartment, i.e. the kneecap and the underlying bone.

As a less invasive surgery, only the arthritic part of the knee is replaced. The kneecap is resurfaced with a plastic button, customized for each patient, and a metallic shield is placed in the trochlear groove of the thighbone.

"I've had a particular interest in this surgery for decades because of the success I have seen with my patients," said Dr. Grelsamer. "With half a million people receiving knee replacements a year, this technique helps many people return to their normal routine due to the shorter recovery and rehabilitation required. Although the surgery may not be appropriate for some situations, patients should be aware of the option."

Dr. Grelsamer, a highly regarded knee and hip surgeon, is at the forefront of orthopaedic research and technology, integrating the latest treatments and surgery options into his practice. Dr. Grelsamer is consistently recognized as one of New York Magazine's Best Doctors of New York, and in Castle Connolly's America's Top Doctors.

Dr. Ronald Grelsamer is an active member of the American Academy of Orthopaedic Surgeons, the Orthopaedic Research Society, the Société Française de Chirurgie Orthopédique et Traumatologique, and the International Patellofemoral Study Group. In February, 1993, he was honored with a grant from the Orthopaedic Research and Education Foundation Award, and, in 1995, with the Research Award from the American College of Sports Medicine – Greater New York Chapter.
