Hospital for Special Surgery (HSS) recently presented findings at the American Orthopaedic Society for Sports Medicine annual meeting. The presentation highlighted advancements in a historic orthopedic procedure, knee osteotomy, which is being revitalized to help patients with bowed legs. This procedure aims to restore proper limb alignment and enhance knee function, potentially delaying or avoiding knee replacement surgery.
Knee osteotomy was first introduced in the late 1800s. It involves cutting and reshaping the shinbone or thighbone to relieve pressure on the knee joint. Initially used as a treatment for arthritis and other orthopedic conditions, its popularity waned with the advent of modern knee replacements in the 1970s. However, surgeons have continued to refine this technique, using it today to address bowleg deformity and prevent knee replacement surgery.
Bowleg deformity can affect individuals of all ages and may result from various causes, including illnesses like Blount’s disease, improperly healed fractures, and vitamin deficiencies.
A comprehensive review led by Anil S. Ranawat, MD, Chief of the Hip and Knee Division of the Sports Medicine Institute at HSS, revealed positive outcomes for patients who underwent knee osteotomy. These patients reported significant improvements in quality of life with less pain and better movement. Dr. Ranawat stated that “the development of new technologies” has enabled surgeons to resolve knee pain more effectively.
Osteotomy has evolved beyond a one-size-fits-all approach due to patient-specific instrumentation (PSI). This involves using a patient’s CT scan and digital software for virtual surgery planning tailored to individual anatomy and needs.
While younger patients under age 50 faced challenges with traditional knee replacements due to high infection rates and complications, new patient-specific technologies have improved osteotomy’s safety and precision. Dr. Ranawat noted that “new patient-specific technologies have revolutionized” this procedure.
HSS continues to lead in advancing knee osteotomy techniques by integrating modern technology to improve surgical precision and outcomes. Dr. Ranawat emphasized their proactive approach: “We want our younger patients to know they don’t have to live with pain or rush into a knee replacement.”
The incorporation of artificial intelligence, machine learning, advanced imaging, and robotic-assisted surgeries is expected to further revolutionize knee osteotomy in the future.
